Title: Protective circuit for semiconductor circuit
Inventor: TAKEUCHI MINORU
IPC: H01L23/62
Filed: 1982-06-28
Abstract: PURPOSE:To attain a protective function without attenuating an analog signal even when the circuit is used for an external connecting terminal transmitting or receiving an analog signal value and without largely increasing chip size by constituting the protective circuit without using a series resistor. CONSTITUTION:With a capacitor 13, one terminal is connected to an input terminal 2, and the other terminal is grounded through a high resistor 14. With a MOST 12, a drain is connected to the input terminal 2 and a gate to a node between the capacitor 13 and the high resistor 14 and a source is grounded, and it emits normal threshold voltage. In the circuit, the gate voltage of the MOST 12 rises instantaneously through the capacitor 13 when high voltage is applied to the input terminal 2. Since the MOST 12 does not emit high threshold voltage as seen in conventional circuits, conductance is large, sufficient currents flow, the voltage of the input terminal 2 attenuates suddenly, and the semiconductor circuit A to be protected is protected.

Title: Field-type conductor sensor
Inventor: OOHASHI HIROSHI
IPC: G01V3/08
Filed: 1979-08-31
Abstract: PURPOSE: To sense the movement of a conductor along the sensing wires without malfunction by arranging a pair of parallel sensing wires on both sides of an exciting wire so that the positions of the sensing wires are interchanged every fixed interval to detect the cyclic change in the difference voltage between the pair of sensing wires.  
     CONSTITUTION: A pair of parallel sensing wires 13 and 14 are arranged on both sides of the exciting wire 12 so that the positions of the sensing wires 13 and 14 are interchanged every fixed interval. When a human body moves along the sensing wires 13 and 14, their induced voltage VD and VE vary with the movement, and the difference voltage VD-VE can be obtained through a differential operational amplifier 15. The difference voltage is compared with a voltage VH in a comparator 16, which generates a pulse when VD-VE>VH. The difference voltage is also compared with a voltage VL in a comparator 17, which generates a pulse when VD-VE<VL. When counting, for example, three pulses outputted from the comparators 16 and 17 through an FF18, a counter 19 drives a transistor 20 to actuate a relay 21. The constitution permits the sensing of the movement of a conductor along the sensing wires as well as prevents the malfunction caused by the swinging trees and the like.

Inventor: TANIGUCHI SHIGEKI
IPC: A47K10/36
Filed: 1988-05-10
Abstract: PURPOSE:To prevent paper from getting wet even if scattered water is spryed over a paper holder by letting a cover be positively supported by the side plates of a substrate box with pivotally supporting members, letting curved rounding section covering the rib of the substrate box be included in the upper rear section, and thereby letting the both side plates of the substrate box and the both side plates of a cover be formed in a size large enough in such a way as to lie upon each other at all time. CONSTITUTION:A substrate box 1 is opened at its front and lower section wherein a rib 5 is provided for the front upper section of it while projections 6 supporting a cover 2 are also provided for the side of the rib 5. And a bar 3 which rotatably supports a rolled paper 4, is pressed into side plates. The cover 2 is rotatably supported by the substrate box 1 with the projections 6 in such a way to cover the side plate sections of the substrate box 1, including a curved rounding section 8 which covers the rib 5 of the substrate box 1 from above, at its upper section. Since the cover 2 lies upon the substrate box 1 at all time, when a holder is splashed with water with the rolled paper mounted, water falls down to a floor along the side direction of the rib 5 provided at the front section, and water scattered onto the cover 2 falls down to the floor from the front and sides of it, thereby preventing the paper 4 inside from getting wet so as to be available for use.

Title: Tap winding for transformer
Inventor: HAYASHI KENICHI
IPC: H01F27/28
Filed: 1977-09-22
Abstract: PURPOSE: To supprrss a circulating currert between a plurality of lines of parallel conductors, by specifically desinging the number of turns and the arrnngement of tap winding divided into two groups, with a point of advantage made remaining to be held as in a case of making a constitution of the tap winding with multi helical windings.  
     CONSTITUTION: Nember of turns per every tap is made larger in taps 1, 3, 5, 7 by one turn of winding than in taps 2, 4, 6, 8. Each tap is situated in a position  vertically symmetrical in the winding, accordingly, a fringing of leakage flux at an  end part of the winding, because of a reverse direction becoming in the flux making  an interlinkage at a top and bottom end just with a loop constructed by each  parallel conductor, will not cause an induced voltage. Consequently, no flow of the  circulating current will eliminate an overheating locally caused in the winding
