Title: Valve operating system
Inventor: KANEKO KIKUO
IPC: F16K41/00
Filed: 1985-02-05
Abstract: PURPOSE:To secure the sealing properties at the valve-rod penetrating section of a valve by providing a sealant around the fulcrum supporting pat located within the valve-rod penetrating section on the cover for capping a valve box. CONSTITUTION:A tapered hole 7 and a supporting hole 8 adjacent to the tapered hole are made at the central part of a cover 5 which is fixed to the edge of the upper opening of a valve box 1. A valve rod 9 is supported at its part in a state where the rod is allowed to function as a lever by the peripheral edge of the supporting hole 8, and a valve 10 is attached to the lower end of said valve rod 9 in such a manner that the valve faces towards a valve hole 2 and also in adjacent to a valve seat 4. A sealant 12 located in the circumference of the supporting hole is fixed so as to be one with said valve rod 9 which penetrates the center of the supporting hole, and the peripheral part of the sealant is held between the upper end of the valve box 1 and the cover 5. The sealant 12 is located in the immediate vicinity of the fulcrum of the circular motion of said valve rod 9, and accordingly, it hardly deforms in spite of the circular motion of said valve rod 9.

Title: Power supply circuit for protecting reverse voltage
Inventor: YAMAMOTO SUSUMU
IPC: H02H11/00
Filed: 1983-02-10
Abstract: PURPOSE:To prevent the circuit destruction of a power supply at reverse connection of the power supply by supplying an input to a control circuit from the midway point between a resistor connected to a power supply terminal and a diode connected reversely. CONSTITUTION:A transistor TR2 for applying load and a control circuit 3 connected to the base and detecting an emitter-base potential and controlling the circuit current are provided to a power supply 1. Further, the power supply connecting section of the circuit 3, i.e., the input point is electrically conducted from the midway point between a resistor 6 connected to the power supply 1 and a diode 7 of reverse connection. If the polarity of the power supply 1 is reversed, a current by the application of reverse voltage flows through a junction separating region existing in the diode 7 and the circuit 3 as a forward current to the junction. Since this current is limited by the resistor 6, the excess of current is prevented.
