Title: Input short-circuit protective circuit
Inventor: TSUMIKI TADASHI
IPC: H02H7/12
Filed: 1992-04-08
Abstract: PURPOSE:To prevent a parasitic effect by the backward bias of an output transistor when an input is short-circuited. CONSTITUTION:When an input is short-circuited to a ground, charges charged in a capacitor C1 are discharged under the state, in which an output is stabilized, and large currents intend to flow through the collector of a transistor Q3 to an emitter and a base. The collector potential of a transistor Q5 is lowered to base potential under the state, and the transistor Q5 intends to make currents flow through the base of a transistor Q4. Accordingly, the base currents of the transistor Q3 are interrupted in order to turn the transistor Q4 OFF and no large current flows, thus preventing the breakage of the transistor Q3.

Filed: 1988-04-08
Abstract: PURPOSE:To quickly execute large-scale optical remainder operation with simple constitution by using only optical deflectors to constitute the principal part of an arithmetic unit and using connection due to space propagation of light. CONSTITUTION:An operand is converted to a remainder system and only a light emitting element driving circuit 11 corresponding to the remainder in this method out of a group of light emitting element driving circuits 10-13 is moved to emit the light of a light emitting element 21.

A light receiving element 42 consisting of, for example, a photodetector which receives this light indicates remainder 2 corresponding to the arithmetic result of this method. It is sufficient for another method if a required number of these elements are arranged. Thus, the position which the deflected light reaches indicates the arithmetic result, and optical arithmetic is quickly performed.

Title: Discharge electrode in lightning insulator
Inventor: FURUKAWA SHUJI
IPC: H01B17/46
Filed: 1990-03-30
Abstract: PURPOSE:To prevent impairment or damage of a transmission line as well as deformation of an arcing horn by providing a bending mechanism in which an arc horn can be bent when its interferes with a transmission line, on at least one portion of the arcing horn on the charging side. CONSTITUTION:When the fore end portion of an arcing-horn body 20b interferes with a transmission line 8, the fore end portion of a rockable member 24 tends to be downwardly rocked about a bolt 29. And the fore end portion of the rockable member 24 depressed only the spring member 28 attached a resilience member 26 against the resilient force of the spring 28. As a result, the arcing- horn body 20b is bent by means of a bending mechanism K. When, thereafter, the arcing-horn body 20b ceases to interfere with the transmission line 8, the horn body 20b is restored in its original condition. Accordingly, impact force which is applied to an arc horn 20 when this horn interfere with the transmission line can be absorbed through operation of the bending mechanism K. This makes it possible to mitigate the impact applied to the transmission line 8, so that the damage caused to the transmission line 8 can be made small. At the time, deformation of the arc horn 20 can be prevented.

Title: Wafer filling device for hot water space heater or the like
Inventor: SHIRE TAKASHI
IPC: F24D3/10
Filed: 1989-04-06
Abstract: PURPOSE:To prevent a large quantity of water from continuing to leak even when the tank is damaged or a pipe is disconnected by providing a water filling valve opening time control means which outputs the water filling valve closing signal to the operation control means so as to close the water filling valve regardless of water level data if the water filling valve opening time exceeds a certain limit. CONSTITUTION:In case where a large quantity of water leaks because of the damage of the expansion tank 1 or the disconnected hot water pipe, the water level in the expansion tank 1 becomes low enough to cause the intermediate water level sensor 7 to be turned off and the water filling valve 5 to open to start filling the expansion tank 1. However, because too much water is leaking, the water level will not rise and the high water level sensor 6 will not be turned on, and so, the water filling valve 5 will not be closed. In this instance, the water filling valve opening time limiting means 11 to which the operation signal of the water filling valve 5 is inputted from the operation control means 10 counts the time interval in which the water filling valve 5 remains open, and, if the time exceeds a certain limit, for instance the time interval which would be required to fill the empty expansion tank 1 to its high water level, the water filling valve closing signal is outputted to the opera tion control means 10. In this way, the operation control means 10 closes the water filling valve 5 regardless of water level data.
