Organic EL Panel Control
Problem: In order to compile a production control history, data such as the lot number, serial number, and production date has to be documented for each panel. Using a paper-based system, though, makes it difficult to achieve complete production control starting at the initial stages of the process. It would be helpful if the panels could be controlled individually instead of in lots. Use an exposure device to directly mark each panel with a 2-dimensional code containing the production data for the glass substrate and the process history data. Read the 2-dimensional codes with a 2-dimensional Code Reader, and control the entire production process over a network.
Controls Parts for High-speed Mounters
Problem: Control is based on instruction sheets and so human error can occur when cassettes are mounted to the mounter. Also, in order to prevent errors, multiple reading is used. This means that work efficiency is low and personnel expenses are high. The remaining number of parts is ascertained, in cassette units, using paper and the human eye. This is insufficient for effective control and leads to large stock losses. In particular, stock inventory is not possible unless the line is stopped for several days. The parts mounted to the mounter are insufficient and there are frequent mounter stoppages due to missing parts. Read the part information (e.g. part number, part name, and quantity) written in the bar code on the part reel, and write the information to the Data Carrier (ID Tag) mounted to the cassette. After mounting the cassette to the mounter, automatically read the cassette information, check the part information and remaining quantity, and perform verification with the mounting program. Use an alarm to provide notification of cassette mounting errors and insufficiencies in remaining parts. After the mounting process is completed, write the latest information on the number of remaining parts, based on the mounter's data, to the Data Carrier.
Individual Wafer Control
Problem: Until now, in the production of DRAM, for example, wafers have usually been processed in lots of 25 (i.e., in wafer carrier units). The switch, however, towards high-diversity, low-volume production (e.g., custom LSI) has made individual wafer control necessary. In order to avoid reducing the number of IC chips produced per wafer, the markings used for individual wafer control must be as small as possible. Mark the back surface of each wafer with wafer ID (2-dimensional code) satisfying the specifications of the SEMI T7 standards using a laser marker. (The surface can be marked with a wafer ID consisting of 13 alphanumeric characters in an area of 4 × 1 mm.). When the wafers are introduced into the processing equipment, read the wafer ID (2-dimensional code) with a 2-Dimensional Code Reader and send the information to the equipment

For inspection processes, write the inspection results (i.e., OK or NG) to the ID Tags. At the end of each process, write instructions relating to process completion flags and the next process as appropriate. At the final process, read all the information in the ID Tags, and store it in the host for lot control.

When the charge/discharge inspection is finished, write classification information based on the inspection results to the ID Tags.

To classify the batteries, read the classification information stored in the ID Tags, and perform sorting (automatically) with a robot.
Automatic Recognition and History Management for Molds

It reads the mold information and molding conditions from the ID Tag using an Antenna (R/W Head) mounted to the molding machine. At the same time, it also reads the shot count, and checks that the mold is within its service life specifications. After the molding process is completed, it writes information (e.g., shot count) from the molding machine to the ID Tag (Data Carrier).

Filling Inspection for Plastic Containers
Problems: Beverage production lines where plastic containers, for example, are filled with liquid, have a short tact time and require a high degree of accuracy. The foodstuff industry is subject to particularly stringent levels of product control (e.g., HACCP). Generally speaking, filling control is performed by measuring the weight of the plastic container once in the empty state and then again after the filling has been completed. The difference is calculated to confirm that the weight agrees with the specified value. Data must be exchanged, however, with the host at each measurement, necessitating a complicated system configuration. If, as a result of the inspection, the filling weight is found to disagree with the specified value, correction is necessary. A way of performing the necessary sorting control quickly, simply, without sacrificing reliability is required. Mount ID Tags to the jigs holding the products. If round jigs are used, mount the ID Tags to the bottom of the jigs and install the Antenna underneath to ensure access even if the jigs turn around. Measure the weight of each container in the empty state and write the result to the ID Tag. Write the filling machine number to the ID Tag to distinguish it from machines at subsequent processes. Measure the weight of the container again after the filling is completed and write the total to the ID Tag. In the weight inspection process, read the empty-state weight and total weight from the ID Tag and check the difference at the host system. At this point, if the difference disagrees with the specified value, send the item to the correction process. At the sametime, read the filling machine number stored in the ID Tag.
Quality Control for Food Products
Problems: Food products demand a high degree of safety. The importance of managing a wide variety of information, such as the date and place of production, the best-before date, and the destination direction is greater than ever and has made quality control of foodstuffs very difficult. Food products cartons are cleaned with alcohol, detergent, warm water, or steam and so machines that have a low resistance to chemicals or high temperatures, or that may allow bacteria to proliferate cannot be used. Mount Data Carriers (ID Tags) housed in a double layer of PFA (Fluororesin) to the cartons or pallets, and in addition to the product name, weight, and quantity, store information regarding the data and place of production, the best-before date, and the destination direction in the Data Carriers. Perform sorting and delivery work after confirming safety using the production date and best-before date information obtained from the Data Carriers and issue a form itemizing the relevant information.
Automated Raw Material Mixture and Measurement System
Problems: Using (paper) instruction sheets leads to incorrect combinations due to misplacement. When incorrect combinations occur, they are not discovered until the final inspection process. In each process, read combination information from the ID Tags mounted to the containers and add the specified weight of each raw material from the hoppers. Write the combination result (i.e., the weight) to the ID Tags.
Automated Inspection and Sorting of Blood Samples
Problems: In systems that perform batch control of sample racks and trays with bar codes, the inspection instructions and sorting information are handled at the host system. This gives rise to complicated programs and configurations, making it difficult to change the system when required. A new bar code label must be attached each time the sample racks and trays are cleaned. The labels have to be attached carefully without being creased. Read information from the bar codes on the test tubes with a bar code reader, and store that information along with inspection instructions and sorting information in the ID Tags embedded in the sample racks and trays. Write inspection history information and inspection results to the ID Tags and, in the final process, upload the information to the host system.
Automation of Systems for Mixing and Measuring Medicines
Problems: Using (paper) instruction sheets leads to mixing errors due to misplacement. Changing the system to accommodate new products is extremely difficult. In each process, read product and mixing information written beforehand to ID Tags mounted to the pallets, and add the specified weight of each substance from the tanks. Write the mixing result (i.e., the weight) to the ID Tags and then read this information in the inspection process to check the actual weight of the contents.

Lot Control and Condition Control in Plating Processes
Problem: Components are inserted in a plating bath for metal plating. When multiple components are inserted, each of the individual components must be managed. Paper and labels are used for this purpose in other processes, but they cannot be used here because the components are inserted into the bath. Human errors and missing components can result because it is difficult to keep track of which components, from which lots, are in the plating process. In some cases, the plating conditions are determined prior to plating and written up into work instructions for manual input. Due to the short life cycles of products today, and the speed at which model revisions occur, this instruction system becomes quite rushed and subject to human error and other mistakes. An operating method with greater accuracy and efficiency is needed. Mount a Data Carrier (ID Tag) onto the plating basket (pallet) carrying the components. Write the component data, lot data, urgent-item flag data, and plating conditions onto the Data Carrier. Mount a R/W Head (Antenna) onto the controller of the plating device. Prior to placing the components into the bath, use the a R/W Head to read the lot data, product data, and plating conditions simultaneously, and automatically make the condition settings for the plating device. In order to achieve more advanced work process management, configure a system that writes the work start and end times for each plating job. This will enable process history and process progress control, making it easy to determine where components are in the process at any time.
Controls Carrier Boxes within Processes
Problem: The components, dies, etc., that are needed for the processing and assembly lines of home appliances are conveyed in carrier boxes or totes. A paper list is placed in the boxes, and the parts are sorted while checking the list at each process. This system is inefficient and lends itself to human error. Many companies would like to improve on it without having to make a large investment. Bar code labels are attached to carrier boxes, and a bar code reader is used to read the labels at each sorting stage. However, when labels become soiled, they cannot be read or they cause reading errors. Or, to lessen the parts control burden on the host computer, companies have switched to a system that issues parts-distinguishing labels for each component instead of carrier box-distinguishing labels, but the cost of issuing the labels and the extra work of replacing them is driving up operating costs. Companies are therefore seeking to improve on this system. Mount Data Carriers (ID Tags) onto the carrier boxes carrying the components. Use a special holder that allows the Data Carrier to be easily mounted and removed for this. Write bit data to the Carrier Data for distinguishing components (for example, 00000000 for component A, 00000001 for component B, 00000010 for component C, and 00000011 for component D; up to 258 components can be distinguished with eight bits). Install a system with Intelligent Flags and a PLC at each process to automatically read the component bits and sort the components accordingly.
Processes and Assembles CRTs and Displays
Problem: Bar code labels or photoelectric mechanical flag seals are attached to the pallets of hanger conveyors that are used to transport small lots of CRTs or monitors for TVs and PCs in the processing and assembly lines. Because the hangers sway, the reading depth changes and the labels or seals sometimes cannot be read, causing the line to stop. The number of models being produced has increased due to diverse user needs and the appearance of LCD and plasma TVs. This has created the need for frequent line changes, and the resulting complex processes make control by a host computer extremely difficult. Mount a Data Carrier (ID Tag) onto the hanger pallet carrying the product. Write the data to distinguish models in bits (for example, 0000 for product A, 0001 for product B, and 0010 for product C, allowing 16 models to be distinguished with four bits). Install a system with Intelligent Flags and a PLC at each process. When the work at each process ends, write the process end flag data onto the Data Carrier. Use a "1" flag for ending, and a "0" flag for not ending (for example, for four processes, use 0001 for the end of process 1, 0011 for the end of process 2, and 0111 for the end of process 3. These will enable process progress management).
Progress Control and History Notification within Processes
Problem: Since the production processing and assembly time, as well as the holding time, for each process in the production line cannot be accurately obtained, it is impossible to determine where to start in making process improvements aimed at raising productivity. Obtaining the progress status for each process in the production line is an important factor in achieving supply chain management (SCM), but it is extremely difficult to control this on a host computer because the processes are split into several branches and then merged. Mount a Data Carrier (ID Tag) onto the pallet carrying the product, or onto a workpiece. In addition to product information, write the work start and end times as they occur for each process onto the Data Carrier. Then, at the final process, read the time data that was written for each process and create a graph containing the process history and corresponding time data to analyze the processes. When the work at each process ends, write the process end flag data and instructions for the next process onto the Data Carrier.
Standardizes and Improves the Operating Rate of Production Lines
Problem: When multiple automated lines are used for production, there is no simple way of standardizing and maximizing the production volume of each line. It is also difficult to determine the operating condition of each automated machine. In a production system where the work results and inspection results from the preceding process are used to determine which automated line the product will be sent to for the next process, control by the host computer is difficult, and errors are extremely troublesome to handle. Mount a Data Carrier (ID Tag) to each pallet, write the work data for the automated machine (automated machine number used, lot number, tool used, work program number, etc.), and use this to send the product and components to an available line. The instructions are read by each automated machine, and the work is done. The work start time and end time are written to the Data Carrier. For inspection processes, the inspection results are written together with the automated line number that should be used next, and the subsequent work is done at that automated line.

Work Instructions for a Construction Equipment Assembly Line
Problem: Human error problems occur because operators are making line changes as they look at paper-based instructions. Store the work instructions (model information, welding instructions, programs, etc.) into the ID Tag, and mount it to the carriage. The work instruction data inside the ID Tag can be read by a non-contact reader to help automate the process.
Instructions for an Auto Body Welding Line
Problem: Human error problems occur because operators are making line changes as they look at paper-based instructions. Bar codes were previously used, but errors occurred in reading. Store the work instructions (model information, welding instructions, programs, etc.) into the ID Tag, and mount it to the carriage. The work instruction data inside the ID Tag can be read by a non-contact reader to help automate the process.
Instructions for a Finished Vehicle Inspection Line
Problem: The efficiency of the present, paper-based system of inspection instructions is extremely poor because the operator has to step out of the vehicle at each step to make the settings. Since the inspection results are entered by hand, human error is likely and the process requires considerable time. Automate the setting process with non-contact reading of the inspection instructions (such as vehicle model data and inspection data) stored in ID Tags. Eliminate manual entry by writing the inspection results directly into the ID Tag in the inspection process.
Tool Management for Machining Centers
Problem: Managing tools for machining centers, lathes, and hobbing machines on paper, by storage location, or by writing directly on the tools with a marker pen leads to delays and processing errors due to incorrect setting. Associating the information required for tool management (e.g., usage time and tool length) with the actual tools is difficult. Process the pull-stud or drive-key groove of each tool so that an ID Tag (dimensions: 8 dia. × 5 mm or 12 dia. × 5 mm) can be attached using adhesive, and store tool management information (e.g. tool number, name, usage time, and tool length) in the ID Tags. In addition, store information obtained by the tool presetter (e.g., initial tool length and compensation values) in the ID Tags.
Tire Types and Destination Discrimination
Problem: The manufacture and delivery of tires is carried out systematically based on a production plan. Urgent items, however, must be sorted by hand, giving rise to human error, such as destination direction, model discrimination, and quantity counting errors. The hangers vary with the size and type of tire and so conveyance efficiency is very low. Sorting is performed using bar codes on the tires but dirt on the label can lead to reading errors and it takes time to check the tires. When mounting a tire onto a hanger, write information regarding the tire type, the destination direction, and urgent-item flags to a Data Carrier (ID Tag) mounted to the hanger. Perform sorting (automatically) based on information regarding the tire type and destination direction read from the Data Carrier using a R/W Head (Antenna) mounted to the sorting point in the hanger conveyance system. Display information related to urgent-item flags on display devices.
Picking Instructions for Assembly Parts
Problem: Performing picking work using (paper) instruction sheets results in human error. Time wasted looking at instruction sheets results in low work efficiency. Store pallet numbers, picking station numbers, and picking instructions (e.g., picking component numbers and picking quantities) to Data Carriers (ID Tags) mounted to the pallets. At each picking station, read the information from the Data Carrier, turn ON the lamp for the rack corresponding to the picking component number and, at the same time, display the picking quantity. The operator puts the displayed quantity of the displayed component in the pallet.
Model Discrimination and Process Control for Engine Assembly Lines
Problem: In engine assembly lines that use mechanical flags and bar codes for model discrimination and process instructions, the production line sometimes has to be stopped because of mechanical failures or other factors, such as not being able to read the bar codes because of oil or coolant. Although mixed production lines can be handled, increasing diversification of client needs has led to further increases in the number of different models, and switching between different types of operation must be performed with more efficiency and stability than ever before. Mount Data Carriers (ID Tags) to the pallets or jigs. Write model information and process information to the Data Carriers, read the information at each process station, and, based on this information, switch the operation type (if necessary) and perform processing. After completing a process, enable the processing completion flag for that process.
Automated Pouring in Casting Processes
Problem: When pouring is based on visual confirmation of a number plate mounted to the mold, the influence of dust, high temperatures, vibrations, or other conditions particular to the production site make work very difficult. The number plate is difficult to see because of dust, increasing the likelihood of human error. The versatility to switch between different types of operation and high work efficiency, essential for responding to a variety of needs, are difficult to attain. Store information about the mold number and pouring hole position in Data Carriers (ID Tags) mounted to the molds. Read the information from the Data Carriers on the molds with an Antenna mounted to the pouring machinery, and perform pouring work (automatically) based on this information.

Heater for an Exhaust Gas Analyzer
Problem: Using our existing 4 to 20mA transmission output to send signals about 40 to 50 meters to the measurement room without having to pay extremely high cable costs. Furthermore, a large number of Temperature Controllers per device (about 25, including 12 for control and 12 for alarms) are required, and space constraint in the heating device control panel. Change the present 4- to 20-mA transmission output to RS-485 for a major education in wiring and labor. Use E5ZN Modular Temperature Controllers to save space.
Shortens Temperature Stabilization Time
When the crucible temperature (sensor 1) is used for control, the crucible itself reaches the set temperature, but the liquid does not. By using cascade control, if sensor 2 and 3 are used for control, the response is slow and sufficient control is sufficient. Bottom line: The liquid temperature needs to reach the set temperature as quick as possible.

The Ionizer can be installed between the guard and the printing stage.
Contractor Entry and Exit Management
Problems: Because the contractors entering and leaving through company gates tend to be concentrated in certain times of the day, the gates become crowded and distribution efficiency drops. This also causes traffic jams in the surrounding roads which inconveniences the local community. An entry/exit control system is necessary that will maintain high levels of security with regard to regular contractors while also increasing efficiency. Install an Antenna at the gates to read data (contractor's name, driver's name, truck number) from ID Tags held by the drivers, and write that data and the entry/exit time to a database. The driver does not need to leave the truck to do this. He can simply face the ID Tag in the direction of the Antenna to pass through the gate. By comparing the times read from the ID Tag when passing through the entry and exit gates, the peak traffic times inside the company grounds can be determined.
Branch Control for Automated Warehouse Delivery
Problems: Components from an injection molding machine are loaded onto pallets and transported by a conveyor belt, but the transport line has a large number of merging and branching locations so it is difficult to trace them at the host system. After setting up the line, several different components are produced by each injection molding machine. A simpler form of control is needed. The simplest, lowest-cost system is desired for sorting and controlling the branching of these components. Write the component classification data onto an ID Tag attached to the pallet following the injection process. Control the branching at a point immediately before the pallet enters the automated warehouse. Use the self-execution mode of the V670 to conduct branching control, thus simplifying control at the host system.
Forklift Management in Warehouses
Problems: Products on pallets are transported by forklift both inside and outside the warehouse, but it is necessary to have better control over forklifts entering and leaving the warehouse for product-liability reasons. Instructions to tell the forklift drivers which warehouse number to go to are generally given either in the form of job sheets or by wireless communications. Sometimes, however, drivers end up going to the wrong warehouse due to human error. A better system is needed. Place an ID Tag on the roof of the forklift (secure with a magnet if necessary). Then install one Antenna each at the entrance and exit of the warehouses. (For the most accurate control, these should ideally be designated as one-way routes. This point must be covered by control measures.) Store the number of the forklift and, if necessary, the name of the driver, in the ID Tag. The Antennas will then read the data from the ID Tag each time the forklift enters and leaves the warehouse, and send it to the host system. A system can also be built so that an alarm is sent to the forklift driver if he tries to enter the wrong warehouse. For additional control, the time that the forklift passes each Antenna can be written to the ID Tag. That data can later be uploaded to a database to show the operational flow of the forklifts.
Warehouse Pallet Control
Problems: Products and components in the warehouse are stacked on pallets (for example, T11 pallets) and managed, but retrieving the specified pallets with a forklift takes too much time because the operators have to visually confirm each pallet, and the operators sometimes make mistakes. A better method is desired. The method of attaching labels, for example, with bar codes, to the pallets has been considered, but the workflow would be much more efficient if the desired pallet could be identified without the operators having to get off of the forklift each time. Attach an ID Tag to each pallet, and write the pallet number onto the ID Tag. Then install an Antenna on the forklift and connect it to a PLC or other control unit on the forklift. The operator can then drive to the pallet storage area by following either a work instruction sheet or wireless communications, confirm that the pallet number read by the Antenna contains the desired cargo, and load it onto the forklift (basic application method). By also writing product information in addition to the pallet number onto the ID Tag, the information that is read by the Antenna when the pallet is loaded onto the forklift can by sent to the host system by wireless communications to help managing distribution control data inside the warehouse.
Cargo Container Management
Problems: Containers are used for transporting a wide variety of cargo, and each time the cargo changes, someone has to issue a paper or plastic plate, mount it to the holder on the container, and visually check the contents for accuracy. This system is not very efficient. When using plates labeled with bar codes for this purpose, the labels get dirty or wet since the containers are used outdoors where they are affected by the climate. The bar codes can then no longer be read accurately, and the overall management lacks stability. Mount an ID Tag to the container holding the cargo, and install an Antenna near the loading and/or unloading locations. Information can then be written to and read from the ID tag mounted to the container. In addition to the basic container number, the ID Tag can also store the necessary cargo data, destination data, station data, date, courier name, contractor name, security data, and more. To provide even more thorough control of the cargo destination, Antennas can be installed at each point to be confirmed along the route and every branching location. The data can then be read as the cargo passes by to make sure that it is following the specified route correctly.
Inventory Control for Automated Warehouses
Problems: Linking warehouse inventory systems based on bar codes to other systems for picking, sorting, or another kinds of operation necessitates the creation of a network. This makes the overall system very complicated. Dirt on bar code labels attached to pallets can cause reading errors. Mount Data Carriers (ID Tags) to the pallets and store the pallet number and information about the contents of the pallet (e.g., component numbers, model numbers, and quantities) in the Data Carriers. In response to a storage instruction, read (automatically) all the information in the Data Carrier, and, after checking the contents, store the pallet in the specified rack, and record the rack number of the stored pallet in the host computer. In response to a delivery instruction from the host computer, take the pallet from the applicable rack, and after checking the pallet information, send the pallet to the picking or sorting process.
Motion Control for High-speed Conveyor
Problems: Motion control for high-speed conveyors, such as OHTs and sorters, can be performed with mechanical flags that use photoelectric sensors and optical communications devices. With systems based on mechanical flags, however, position displacement caused by shocks and vibration can result in malfunctions. Wear-and-tear can lead to problems related to light-source deterioration, and malfunctions due to dirt can occur. In order to develop a faster system, a greater level of autonomy is needed. RFID technology would give the required level of autonomy but, generally speaking, the communications speed would be too slow. Mount ID Tags to the OHTs and install Antennas at stations and junctions as required. Store OHT unit numbers and other relevant information in the ID Tags. When an OHT reaches a station, read the unit number with the Antenna, and send the OHT to the specified location by switching points as necessary via the control system (e.g., PLC) connected to the Antenna.
Enhances Automatic Control of AGVs
Problems: There are AGVs (Automatic Guided Vehicles) and RGVs (Rail Guided Vehicles) that run while sensing magnetic tape attached to the floor. They must stop at stations to load or unload cargo, and control is required to ensure that they proceed in the correct direction at junctions. This kind of control can be performed with wireless devices and sensors but depending on the installation, positioning, and environmental conditions, the sensors used may not have sufficient detection accuracy. A way of allowing the system to be changed more simply is needed. Embed Data Carriers (ID Tags) in the stations and at junctions. Incorporate an Intelligent Flag in each vehicle and connect it to the PLC or (Control Board) already built into the vehicle to control vehicle motion. Write the station number or junction number in the Data Carriers as bit data (e.g., 00000001 for station 1 and 00000010 for station 2). Either program control information (e.g., stop, decelerate) for each station in the PLCs, or send control information to the PLCs when required using a wireless device. Motion control of the AGVs will be based on the data read by the Intelligent Flags.

Efficient Management of Construction Equipment Rentals
Problems: Rental management of large equipment like construction equipment is often done by hand using a control ledger, but this results in considerable added work, such as entering the paper-based data into a personal computer for management. A more efficient and accurate system is desired. Because rental equipment is generally stored outdoors, it is necessary to use metal labels for bar code control, which raises costs. Use screws to mount an ID Tag directly to the construction equipment, and write the vehicle data and control number onto the ID Tag in advance. Each time the equipment is rented, add the customer data and rental period information to the ID Tag, and send this data to the control host. Install Antennas at the entrance/exit gates, then read the ID Tag data when a truck transporting the construction equipment passes through the gate, and send that information to the host for use in controlling all equipment that leaves the site. When the rental equipment is returned, read out the data from the ID Tag that is attached to the equipment as it passes through the gate, and simultaneously retrieve the rental information from the control host software. * The antenna conforms to IP62, and should be housed in a waterproof box. Consult your OMRON representative concerning the location for installing the Antenna when using a microwave-type RFID, because the signal sometimes reflects off of metal, or interferes with wireless LAN systems.
Motion Control for Raw Material Transportation Systems
" Problems: Tracking control can be used to move AGVs around a factory to transport roll paper for printing. Using tracking control, however, means that the AGVs must be moved in order, and a large amount of time is lost waiting in line. With tracking control, the motion of the transportation vehicles is determined in advance and it is very difficult to make operation changes (e.g., interruptions). Write motion instructions (e.g., type, destination) to Data Carriers (ID Tags) mounted to the AGVs. Read the Data Carrier information at the stations and perform motion control of the AGVs as appropriate (e.g., instructions to move to material supply stations, standby stations, or production stations). "
Fruit Sorting Systems
Problems: Selecting, sorting, or delivering fruit using mechanical flags (for variety discrimination) on special pallets gives rise to complicated mechanical parts with frequent malfunctions. Creating new mechanical flags to deal with new varieties uses up time and money. Water and dirt can cause reading errors in bar code systems. Store information obtained by a sorting machine, such as size, grade, and sugar content, in the Data Carriers (ID Tags) mounted to the pallets. Position Intelligent Flags at the sorting stations, read the information from the Data Carriers, and sort the fruit according to size, grade, or sugar content.
Management of Rental Machinery
Problems: Warehouse inventory control of rental machinery is complicated because it involves many different items. For example, it is necessary to keep track of which machinery has been rented out, which machinery has been returned, and what condition the machinery is in (e.g., how clean it is). Clerical errors can occur in management systems based on hand-written forms. Collating all the information into, for example, daily or monthly reports can be very difficult. Perform inventory control using ID Tags mounted to the machinery. Write information about the machinery, such as the machinery number and the status of the machinery (e.g., reserved/available, processed/not processed after return, clean/dirty), to the ID Tag.

Operational Control for Construction Tramcars
Problems: A company wants to automate the control of tramcars that are used to transport machinery and materials for tunnel construction and other works, in order to increase worker safety and improve the work environment. It is difficult to determine the present location and destination of the tramcars using a control system of only wireless devices and sensors. Mount an Antenna to the tramcar, and connect it to the equipment for controlling the tramcar operation (programmable controller, wireless device, etc.). Position an ID Tag at each point along the track where control is required. Write the basic position information into each ID Tag. The tramcar can then run automatically (stop, slow down, branch, etc.) according to instructions issued from above ground by wireless communications, while reading the data in the ID Tags.
