Title: Drive circuit of mosfet
Inventor: KAGAYA ISAMU
IPC: H03K17/687
Filed: 1985-07-19
Abstract: PURPOSE:To attain a drive circuit of a power MOSFET of wide dynamic and static control ranges by providing two circuits each of which a transistor TR and a transformer are connected in series and setting the ratio of turn-on of turn-off to 50% at most. CONSTITUTION:When the input of a control pulse 1 is in the low level, a TR 4 is turned off and a TR 3 is turned on, and an FET 1 is turned on by the output of a pulse transformer 16. When the input of a control pulse 2 is in the low level, the FET 1 is turned on similarly because the same circuit consisting of TRs 3 and 4, the pulse transformer 6, a diode 18, etc. is connected in parallel. When control pulses 1 and 2 are in the high level together, TRs 4 are turned on and TRs 3 are turned off in two said circuits, and a TR 2 is turned on to discharge the eletric charge charged in the gate of an FET 1, and the FET 1 is turned off.

Title: Gas flow regulating valve
Inventor: NISHIYAMA TOSHIKAZU
IPC: F16K1/00
Filed: 1982-09-10
Abstract: PURPOSE:To perform good flow regulation over entire region by moving a valve body back and fro in axial direction through rotation of a link while forming the valve body such that the flow will always change linearly with the rotary angle of link. CONSTITUTION:Upon rotation of a valve shaft 6 by means of a link lever 7, a valve body 2 fixed integrally on a valve rod 3 through a coupling rod levers 4, 5 will move back and fro to vary the flow path area formed between section A of the valve body 2 and section B of a valve seat 8 to vary the flow of fluid to be controlled. Here the profile of the valve body 2 is formed such that the flow will change linearly even when the back and fro motion stroke of the valve body 2 has changed. In other word, the profile (the curve of the outer face at section A) of the valve body 2 is determined on the basis that the variation of said flow path area against the rotary angle of the valve shaft 6 is always maintained constant while correcting the resistance (flow factor). Section C of the abdomen 9 of the valve body 1 is formed into such shape as inflated in accordance to proper curve.

IPC: G01S19/24
Filed: 1993-06-29
Abstract: PURPOSE:To enable the building of analog/digital conversion means and a simplification of the structure of the apparatus without using any special element. CONSTITUTION:A signal received with an antenna 10 is supplied to three systems 34-1 to 34-3. The systems 34-1 to 34-3 are each provided with one A/D converter 22.

Title: Gate turn-off thyristor
Inventor: HAGINO HIROYASU
IPC: H01L29/744
Filed: 1979-12-05
Abstract: PURPOSE:To increase the maximum gate turn-off current of a gate turn-off thyristor by uniforming the impurity concentration in the intermediate P type base region to be connected to the gate electrode so that the trasnverse resistance of the P type base region is lowered without decreasing the reverse gate-cathode voltage. CONSTITUTION:After a P type impurity is diffused into both surfaces of an N type semicondcutor substrate 3, the P type impurity layer on one surface is removed by lapping or the like to form an NB layer 3 and a PE layer 4. Then a PB layer to be an intermediate P type base region having a uniform impurity concentration is formed by epitaxial growth. After an N type impurity is selectively diffused to form an NE layer 1 to be an N type emitter region, electrodes are formed for the NE layer 1, PB layer 2 and PE layer 4 to obtain a gate turn-off thyristor. Thus, because the impurity concentration in the intermediate P type base region is uniform in the depth direction, the turn-off current can be increased without decreasing the reverse gate-cathode voltage.

Abstract: PROBLEM TO BE SOLVED: To provide a photoconductive element free from exfoliation between an electroconductive substrate and a photoconductive film by providing an adhesion- reinforcing film between the electroconductive substrate and the photoconductive film. SOLUTION: A photoconductive film 3 which is an amorphous film based on silicon atoms is provided on an electroconductive substrate 2, and a surface protecting film 4 is laminated on the photoconductive film 3. Further, an adhesion-reinforcing film 5 is added between the electroconductive substrate 2 and the photoconductive film 3.
