IPC: H02P1/52
Filed: 1980-11-11
Abstract: PURPOSE:To reduce the capacity of an AC reactor on an output side by a construction wherein a current flows through a power rectifier and a power inverter in the same direction both at the time of starting and at the time of regenerting power. CONSTITUTION:At the time of starting, circuit breakers 3, 4 for starting are closed to energize a controlling circuit for the power rectifier 10a on the system side and a controlling circuit for the power inverter 11a on the synchronous machine side. When the synchronous machine 1 having reached a predetermined speed, a circuit breaker 8 for synchronous parallel operation is closed by an automatic synchronizer, followed by opening the breakers 3, 4. At the time of regenerating power, the breaker 8 is opened and circuit breakers 5, 6 are closed, and power is regenerated through the power rectifier 10a and the power inverter 11a. Accordingly, the current flows in the same direction in both cases of starting and power regeneration, and the capacity of the AC reactor 7 on the output side can be reduced.

Filed: 1978-12-20
Abstract: PURPOSE: To make it possible to appreciate stability of a breakdown voltage in a short time with a high precision by leaving a PN-junction as it is after flowing the breakdown current to the PN-junction at a prescribed temperature for a prescribed time, and comparing the breakdown voltage of the PN-junction after this operation and the breakdown voltage before the test with each other.

Title: Buffer circuit
Inventor: ORITANI ATSUSHI
IPC: G11C8/06
Filed: 1980-11-12
Abstract: PURPOSE: To increase an operation speed by feeding the output of a buffer circuit back to a front stage and by increasing variations in input signal relatively.  
     CONSTITUTION: When an input A changes from a level L to a level H, a transistor (TR) Q 1  turns on to hold an output B at a level L, and then a TRQ 3  turns off to hold an output C at a level H. Consequently, a TRQ 5  is driven to turn on, and a comparison voltage drops, so an input voltage to the Q 1  rises relatively. As the input A goes down to the level L, the Q 1  turns off and the output B goes up to the level H. Therefore, the Q 3  turns on and the output goes down to the level L, so the Q 5  is driven to turn off, so that the input voltage to the Q 1  drops relatively.
