Abstract: A welding machine power supply apparatus outputs welding current in accordance with welding conditions set through operation of a display and setting unit (20). When a welding operation is ended while the welding machine power supply apparatus is operating, the welding conditions effective at the time the welding operation is ended are automatically stored in a memory (16). When any ones or more of the welding conditions at the time when the welding operation is resumed by the use of the welding machine power supply apparatus are different from the one or ones which were effective when the welding operation was ended, a load button (70), a rotary encoder (64) and a set button (72) are operated to cause a control unit (14) to read out the welding conditions stored in the memory (16) which were effective when the welding operation was ended, and to set the read-out welding conditions in the welding machine power supply apparatus.

Abstract: A card includes a magnetic track portion on which value information representing a prepaid amount and one of serial number data consecutively assigned in an issuance order are magnetically recorded, and a serial number printing portion in which a number representing the serial number data is marked with a laser beam. A card issuing apparatus includes a recording/reproducing unit and a laser marking unit. The recording/reproducing unit magnetically records value information representing a prepaid amount and one of serial number data consecutively assigned in an issuance order in a first area of the card, and reads out the serial number data magnetically recorded in the first area. The laser marking unit marks a number represented by the serial number data read out by the recording/reproducing unit in a second area of the card with a laser beam.

Abstract: A card includes a magnetic track portion, a first bar code area, and a second bar code area. Value information representing a prepaid amount and management information for card management are magnetically recorded in the magnetic track portion. The first bar code area is formed parallel to the magnetic track portion at a position not overlapping the magnetic track portion. The first bar code area is recorded with a first bar code representing the value information. The second bar code area is formed in a direction perpendicular to the first bar code area at a position not overlapping the first bar code area. The second bar code area is printed with a second bar code representing the management information. A method of checking this card is also disclosed.

Abstract: A card issue system includes a data terminal, a card issue apparatus, a common memory, interface, and a data bus. The data terminal receives card issue information including a card issue command. The card issue apparatus performs a card issue process on the basis of the card issue information from the data terminal. The common memory is arranged in the card issue apparatus and stores card issue process result information. The interface performs data interface between the data terminal and the card issue apparatus, and the card issue information from the data terminal is transmitted to the card issue apparatus through the interface. The data bus connects the common memory and the data terminal, and the card issue process result information stored in the common memory is transmitted to the data memory through the data bus.

Abstract: A magnetic card includes a magnetic layer, a bar code, a protection layer, and a pseudo bar code. The magnetic layer is formed on a substrate, records magnetic information, and reflects light. The bar code is formed on a predetermined area of the magnetic layer by a light absorption material and detected by a lack of reflected light from the magnetic layer. The protection layer is formed on the predetermined area of the magnetic layer and protects the bar code. The pseudo bar code is formed on the magnetic layer and intermingled with the bar code. An address information code is provided on the card for determining the bar code form the pseudo bar code. A card reader apparatus using this magnetic card is also disclosed.

Abstract: A data write apparatus includes a card conveyor path, a recording head, a sensor circuit, a Central Processing Unit (CPU), a drive circuit, and an enable section. A magnetic card is conveyed in the card conveyor path. The recording head is arranged on the card conveyor path and performs a recording operation on the magnetic card by energizing a winding coil. The sensor circuit is arranged on the card conveyor path near the recording head and detects the magnetic card conveyed in the card convey or path to output a detection signal. The CPU outputs write data to be written on the magnetic card in response to the detection signal from the sensor circuit. The drive circuit energizes the winding coil of the recording head on the basis of the write data from the CPU to perform the recording operation.

Abstract: A task processing apparatus includes a main CPU, a plurality of sub-CPUs, a first starting section, a second starting section, and a notification section. The plurality of sub-CPUs independently execute a series of difference tasks set in advance in accordance with a predetermined sequence. The first starting section is arranged in the main CPU to output a first starting signal for starting the first sub-CPU, of the plurality of sub-CPUs, which executes a first task at the start of the series of tasks. The second starting section is arranged in each of the sub-CPUs except for the last sub-CPU. When the task in a given sub-CPU is completed, the second starting section outputs a second starting signal for starting the next sub-CPU which executes the next task. The notification section is arranged in the last sub-CPU of the plurality of sub-CPUs. The notification section supplies a processing completion signal indicating completion of the series of tasks to the main CPU when the last task is completed.

Abstract: A card loading device includes an elevator, a roller, a card loading port, and two sensors for detecting the feeding of cards, exhausting the feeding of cards and the reloading of cards. The elevator raises/lowers a plurality of accumulated cards. The roller is arranged at a card feed position and rotated clockwise to feed a card located at an uppermost position of the accumulated cards and brought into contact with the roller when the elevator is raised. The card loading port has an opening slightly larger than a thickness of a card and loads a card fed by the roller. The two sensors can detect the proper and the improper loading of a fed card at the card loading port. When a card has been improperly loaded, the sensors send a signal that reverses the roller direction (counterclockwise) and lowers the elevator, thereby exhausting the card from the card loading port.
