摘要： PURPOSE:To make information on the payment, the balance or the like so as to be correctly controlled, by making a cash cassette for wrong apparatus so as not to be attached to an automatic cash transaction machine suitable for direct numerical control. CONSTITUTION:In a cash cassette storage space of an ATM (automatic cash transaction machine) 1, there is provided with an identification card reading part 2 for equipment numbers, payment, balance and so on. An identification card memory body 4 is attached to a surface, coming into contact with the ATM1, of a cash cassette 3 to be attached to the ATM 1. Information on equipment numbers of the ATM 1 to be attached, payment, balance and so on are stored in this identification memory body 4. If this cash cassette 3 is attached to the ATM 1, information of the identification memory body 4 is read by the identification card reading part 2, and the contents are checked. When this read identification information is not for the said ATM 1, it is judged to be nonconformance, and such an alarm that rejects this is generated.

摘要： PROBLEM TO BE SOLVED: To suppress increases in the output capacity, size, and cost of a switching type AC signal amplifier. SOLUTION: An adding circuit 2 adds the input voltage Vin inputted from an AC signal source 10 to the switching type AC signal amplifier 1 to a feedback voltage Vfb and a pulse-width modulating circuit 4 converts the added signal Va into a switching signal Vs. An inverter circuit 5 amplifies the electric power of the signal Vs and an output voltage Vout is outputted through a filter 7. The output current Iout of the inverter circuit is detected by a current detecting circuit 6 and converted into a voltage signal Vfb by a current/voltage converting circuit 8 which has a feedback coefficient and forms a feedback circuit. Here, the output impedance of the amplifier viewed from the amplifier and an output terminal is equal to the feedback coefficient and held constant even if the output current Iout or the AC signal inputted from the output terminal vary owing to the variation of a load 11, so that the above output impedance functions as active output impedance.

摘要： PROBLEM TO BE SOLVED: To prevent decrease in reliability of an inverter by carrying out stopping operation of an inverter using a normal microprocessor, even when abnormality is caused in a microprocessor of a controller in a pulse width modulation inverter having a plurality of microprocessors. SOLUTION: A PWM control means, with a plurality of microprocessors CPU 1, 2, and 3 and common memories 4 and 5, is provided. In this case an increment count value (counted value) of the microprocessor itself is stored in the common memory among the microprocessors. When other count values are not detected directly another microprocessor between them detects the counted value and creates an abnormal detection flag of the defective microprocessor, and the abnormal detection flag is stored in the common memory. In this way, mutual operation of microprocessors are detected, and a microprocessor that falls into failure is subjected to a hard restart treatment from hard watchdog timer circuits 7 and 8, while normal microprocessors are used for breaking an breaker 58 or carrying out a stop treatment of a PWM signal 41 to an inverter 51.

摘要： PROBLEM TO BE SOLVED: To provide a vehicle control device excellent in vibration resistance and having improved reliability by substituting a part of printed wires with fuses on a printed circuit mounting the electronic parts of the vehicle control device. SOLUTION: In a vehicle control device 1 constituted of a printed circuit, printed wire fuses 11a, 11b, 11c are used at a portion of a power feed printed wire 10 to a vehicle control device 6 near a connector 13, and they are connected to the connector 13 via a wiring material 12∥a. Printed wire fuses 11d, 11e, 11f are likewise used at a portion of a signal transmission printed wire to a vehicle control device 7 near a connector 14, and they are connected to the connector 14 via a wiring material 12b. The printed wire fuses 11a-11f are made narrower in width than the other printed wire 10 to be easily fused by an overcurrent. When a short-circuit state occurs on the vehicle control devices 6, 7 or cables 8, 9, one of the printed wire fuses 11a-11f is fused.
