Title: Drive circuit for high voltage high speed semiconductor switch
Inventor: TAKEYASU YOSHIYUKI
IPC: H03K17/78
Filed: 1986-02-24
Abstract: PURPOSE:To eliminate the need for a special shield for an optical coupling part by realizing the insulation between a high voltage circuit and a drive circuit through the optical coupling so as to attain the miniaturization and so as to use a modulation light for the transmission of a switch signal thereby eliminating the effect of an external disturbing light. CONSTITUTION:A high voltage power supply 1 is impressed to a load 1 via a transistor (TR) 2. Then a signal to switch TR 2 is fed from a photodetection demodulation circuit 9. A pulse generator 7 decides a time to switch the TR 2 and the pulse from the pulse generator 7 drives a light emitting element 8. Then light subjected to modulation by the pulse generator 7 and the light emitting element 8 is irradiated onto the circuit 9, which demodulates the modulated light to supply a switch signal to the TR 2. Further, a continuous light generated from a DC power supply 4 and a light emitting element 5 is irradiated to a photoelectric battery 6, resulting that the battery 6 generates a voltage and supplies power to the circuit 9. Then the insulation between the high voltage circuit and the drive circuit is executed by the optical coupling between the light emitting element 5 and the battery 6 and between the light emitting element 8 and the circuit.

Title: Electromagnetic shutter
Inventor: MURATA YOSHITAKA
IPC: G03B9/10
Filed: 1986-02-24
Abstract: PURPOSE:To improve the moving speed of shutter blades with the small quantity of input energy by holding the shutter blades at their closed states against the elastic force of an elastic member and generating electromagnetic force in the traveling direction at the start of traveling of the shutter blades. CONSTITUTION:A shutter front blade 1a rotates a shutter rear blade 1b against the elastic force of a spring 8. Consequently, the spring 8 is electrostatically charged, electromagnetic force reversed from the charging direction is generated on flat coils 2a, 2b and the blades 1a, 1b are released from their holding states. Simultaneously, electromagnetic force in the same direction as the elastic force of the spring 8 is applied to the blades 1a, 1b and the blades 1a, 1b are rotationally traveled in accordance with the force. Since the blade 1b starts to travel with a time delay from the blade 1a, a slit is formed between the blades 1a, 1b and exposure can be attained. Since auxiliary force is applied to the blades 1a, 1b by the electromagnetic force at the start of traveling, the blades 1a, 1b are rapidly traveled. Thereby, increasing input energy can be reduced.

IPC: G01R31/08
Filed: 1990-02-21
Abstract: PURPOSE:To speedily and accurately specify an accident occurrence position without making a patrol by impressing a voltage to an area where the gas insulation opening and closing device(GIS) is stopped from operating because of the presence of a ground fault point, and deciding the ground fault point. CONSTITUTION:For example, a ground fault accident occurs in a section 16 of the GIS which is sectioned with insulating spacers 10 and 11. A generated arc moves fast in the GIS along a conductor and stops at the spacer 11 and the arc stays at the insulating space part until a ground fault current is cut off. Breakers 1 - 4 are tripped under the command of a protection relay and a thick-line part is disconnected from the system. In this state, an AC power source 17 is connected to the secondary side 8a of a gas PT (gas insulation voltage transformer) 8 for an A type bus to excite the PT 8 reversely and when an AC voltage is impressed to the stop range of the thick-line part, partial discharger is caused at the spacer 11 which is damaged by the arc at the time of the ground fault because of an AC voltage generated by the reverse excitation. A high frequency pulse voltage which is induced owing to the partial discharge is detected by the buried electrode of the insulating spacer. Further, the damage insulating spacer is specified.
