Title: Semiconductor device
Inventor: YOSHIMOTO HIDEAKI
IPC: H01L21/768
Filed: 1984-04-06
Abstract: PURPOSE:To produce a compact MOSFET subject to high output while improving the current density by a method wherein drain region and source region are subdivided into multiple regions to make electrode come into contact with any specified parts through the intermediary of insulating films. CONSTITUTION:An insulating film 13 comprising e.g. a silicon oxide film is formed on a substrate 10 while electrode layers 14-1, 14-2, 15-1, 15-2 respectively coming into contact with each region 11-1, 11-2, 12-1, 12-2 are formed through the intermediary of contact holes formed into the insulating film 13. Besides, a gate electrode 16 is formed between drain regions and source regions through the intermediary of a gate insulating film 20 and then a silicon oxide film 17 covering the surface is formed while a conductor layer 18 connecting the drain regions 14-1, 14-2 with each other and another conductor layer 19 connecting the source regions 15-1, 15-2 with each other are formed through the intermediary of contact holes formed into the silicon oxide film 17. Resultantly, an MOSFET subject to high output and high speed operation may be produced since the mutual conductance of MOSFET and the current between drain and source regions are increased while the ON resistance between drain and source regions is decreased.

IPC: H03M7/16
Filed: 1984-04-06
Abstract: PURPOSE:To convert gray codes into binary codes with the small volume of a program by noticing the regularity of the gray codes to convert the gray codes into the binary codes. CONSTITUTION:Generally, the conversion of gray codes Bn-1, Bn-2...B1, B0 into binary codes has regularity for converting the gray codes by the processing of (n-1) times such that B0 is inverted if B1=1(1), B1 and B0 are inverted if B2= 1(2), Bm-1 and after are completely inverted if Bm=1(m), and Bn-2 and after are completely inverted if Bn-1=1(n-1) when the least significant bit (LSB) is B0 and the most significant bit (MSB) is Bn-1. Thus, the gray codes are converted into the binary codes by using said regularity.

IPC: H01F7/16
Filed: 1989-03-20
Abstract: PURPOSE:To bring the operation of an actuator into the state of certainty by a method wherein a current value is changed according to the direction of power supplied to a coil by a driving circuit. CONSTITUTION:When a control signal is inputted to a terminal 14, a current is made to flow to a coil 8 from a power source 12, plasma 9 moves to one side against the energization of a spring member 10 by the magnetic field of the coil 8, and the plasma 9 comes in contact with a base 11A. Then, when the power supplied to the coil 8 is stopped, a plunger 9 is supported in the state wherein it is brought into contact with the base 11A by the magnetic field of a permanent magnet 11. Then, when a control signal is inputted to a terminal 15, a current is made to flow on the coil 8 from a power source 12 passing through another path, a magnetic field is generated on the coil 8 in the direction where the magnetic field of the magnetic field 11 is negated, and the plunger 9 is shifted to the other direction. Accordingly, the value of current is controlled according to the load of the plunger, and a solenoid device 7 can be functioned reliably as an actuator by adjusting the magnetic field generated on the coil 8.

IPC: H01L23/50
Filed: 1990-03-19
Abstract: PURPOSE:To improve an assembly accuracy and workability to insert a lead pin to a printed wiring board by providing a second cut bending section, which is cut and bent in a slanting manner to the surface of a second band body and a band-shaped end whose width is narrower than the width of the second band body. CONSTITUTION:Printed wiring boards 9 and 10 are successively fitted into respective second band bodies A, B, and C by way of through holes 9a and 10a, corresponding to respective second band bodies A, B, and C. They are positioned and maintained hierarchically at each first cut bending section 5 belonging thereto and at a position opposite to a second cut bending end 6 whose width is narrower than the width of the second band body A, B, and C. Each cut bending section 2 is accordingly deformed as the printed wiring boards 9 and 10 are inserted, which does not prevent their insertion. They are returned to their original positions when the printed wiring boards are located at an opposite position having a span equivalent to the thickness. This construction makes it possible to keep each mutual span between the printed wiring board and the right angle between the printed wiring boards and lead pins accurately, thereby improving the assembly accuracy.

Filed: 1990-03-19
Abstract: PURPOSE:To perform the same access operation as that of an ordinary RAM cell as providing with a RAM function also with a ROM function by mixing a RAM cell and a ROM cell in the same cell area of a semiconductor chip. CONSTITUTION:Each of the ROM cells 2a, 2b is comprised of one transistor and one capacitor similarly as the RAM cells 1a-1d. Since the ROM cell 2a always outputs a signal with an H level to a bit line, the inverse of BL 2 by turning on the transistor TR5 when a word line WL2 is selected and goes to the H level, it goes to the ROM cell which outputs (H) based on selection. Also, the ROM cell 2b goes to the ROM cell which outputs (L) by turning on the transistor TR6 when a word line WL4 is selected and goes to the H level. Therefore, it is possible to read out cell information by making access the ROM cells 2a, 2b similary as access to the RAM cells 1a-1b.

IPC: F02M7/08
Filed: 1979-06-04
Abstract: PURPOSE: To avoid amount variations of fuel discharged by an acceleration pump by connecting a damper case which is devided by a diaphragm in a damper equipment to a pump barrel of the acceleration pump.  
     CONSTITUTION: Once a throttle valve 1 is abruptly opened, a piston 3 of an acceleration pump 2 coincident with the valve comes in motion, causing fuel in a pump barrel 5 to be ejected from a nozzle 7 via a check valve 6. The nozzle 7 blocks inrush of fuel so that a pressure in the pump barrel 5 rises high. A diaphragm 9 in a damper case 11 connected to the pump barrel 5 is pulled against a spring 10 to moderate the pressure rise. Fuel discharged from the acceleration pump 2 can be prevented from varying in amount.
