Title: Semiconductor integrated circuit
Inventor: IKEDA ISATO
IPC: H01L27/08
Filed: 1984-06-04
Abstract: PURPOSE:To obtain the same capacitance by a capacitance element having a small area by making film thickness in a region for the capacitance element thinner than that in regions except said region. CONSTITUTION:A gate oxide film 4a, which is interposed between a first polycrystalline Si layer 3 and a second polycrystalline Si layer 5 and forms a capacitance element, is shaped in thickness thinner than a gate oxide film 4b in a section, which is the same layer as the oxide film 4a and does not form the capacitance element. When potential is applied between the first polycrystalline Si layer 3 and the second polycrystalline Si layer 5, charges are stored in the gate oxide film 4a. Since the thickness of the gate oxide film 4a in a region in which the capacitance element is shaped is made thinner than that of the gate oxide film 4b in another region at that time, the capacitance of the capacitance element is made larger than that of a device in which the whole film thickness of a gate oxide film 4 is equalized. Accordingly, the degree of integration of a semiconductor integrated circuit can be improved.

Title: Method and device for tube-bending by using high frequency induction heating
Inventor: YOSHIDA MIKI
IPC: B21D7/16
Filed: 1985-05-29
Abstract: PURPOSE:To equalize a heating temperature and a cooling speed on the periphery of a working tube, and to reduce a variance of a material characteristic by making an air flow in the forward direction by jetting air to the rear side of a heating part, and preventing a jet cooling water from being returned into the heating part by this air flow. CONSTITUTION:A high frequency current is supplied to a high frequency induction heating coil 3 from a high frequency power source 2, and a part right under the heating coil 3 of a tube 1 to be bend-worked is heated. In this case, coolins water is supplied to the hollow inside of the coil 3 from a feed water pump 10, also it is jetted to the tube 1 from many jet nozzles which is provided on the heating coil 3, and the part to which a heating bend is ended is quenched. In this case, air is jetted vertically extending over the whole periphery of the pipe 1 from an air ring 9 through a feed pipe 13 from an air pump 12. Air hits against the surface of the pipe 1, flows forward and backward in the axial direction, and the air flow in the forward direction prevents cooling water jetted from the cooling water nozzle from being returned into the heating part. When the heating part is heated up to a hot working temperature area, the pipe 1 is bended by turning a turning arm 8 by an extruding device 4.

Title: Lubricating oil pressure adjusting device of internal combustion engine
Inventor: MASUDA GOJI
IPC: F01M1/16
Filed: 1990-05-07
Abstract: PURPOSE:To optimally control the control of lubricating oil pressure of an internal combustion engine by controlling the pressure to open a relief valve receiving each signal of oil temperature, engine revolution, and oil pump outlet side hydraulic pressure. CONSTITUTION:A control unit 20 controls the electricity conducting state to an electromagnet 17 receiving each signal from an oil temperature sensor 21 to detect main gallery oil temperature, revolution sensor 22 to detect the revolution of an engine, and hydraulic pressure sensor 23 to detect the hydraulic pressure of the outlet side of an oil pump. The pressure to open a relief valve is variably controlled by moving up a movable body 15 due to the repulsion of the electromagnet 17 and a permanent magnet 19. Due to this constitution, the supply oil pressure by an oil pump 2 is lowered mainly in middle speed area while the oil temperature is high. Therefore, the friction of an engine and the drive resistance of the oil pump 2 in the middle speed area can be lowered to perform the optimum control of lubricating oil pressure.

Title: Erasing method for non-volatile semiconductor memory device and non-volatile semiconductor memory circuit
Inventor: SHIMAZAKI TAKAAKI
IPC: G11C17/00
Filed: 1990-05-02
Abstract: PURPOSE:To improve the controllability of a threshold voltage after erasion and to prevent erroneous erasion by impressing a voltage on a control gate in the case of erasion, detecting a channel current and simultaneously interrupting the impression of a high voltage for erasion. CONSTITUTION:The high voltage for erasion is impressed to a source 6 or a drain 7, and the desired voltage for threshold value control is impressed to a control gate 5. Then, a device 8 to detect the channel current is connected to the source 6 or the drain 7, and the impression of the high voltage for erasion is interrupted simultaneously with the detection of the channel current. Namely, when the high voltage for erasion is impressed on the source 6 or the drain 7 and the threshold voltage is lowered since electrons escape by a floating gate 3, the channel current starts flowing after the threshold voltage is almost equal to the desired voltage impressed on the control gate 5. This channel current is detected and simultaneously, the impression of the high voltage for erasion is interrupted. Thus, the threshold voltage to be regulated by the voltage impressed on the control gate 5 can be obtained.

Title: Inversion device for chip bonder
Inventor: KARASAWA NOBUKICHI
IPC: H01L21/60
Filed: 1979-09-10
Abstract: PURPOSE:To invert an arm for adsorbing a chip fixed to a rotary axis by linking a lever oscillating recillating reciprocally with a toothed wheel by a coupling rod wherein a pinion engaging with the toothed wheel is rotated. CONSTITUTION:A chip is adsorbed to the nozzle of an arm when the curve 20a with the minimum diameter of a cam 20 reaches a lever 23 and the lever 23 will rotate when a curve 20b reaches the lever and a toothed wheel 27 rotates in the same direction through a coupling rod 30. A pinion 36 will rotate due to the above process and the arm fixed to the pinion turns reversely. When a curve 20c with the maximum diameter reaches the lever 23, the nozzle will stop at a predetermined position and a working gadget falls down on the nozzle by a separate mechanism to receive the chip by synchronizing control and the working gadget 15 will rise after adsorbing the chip. Then, when the curve 20d of the cam 20 reaches the lever 23, the lever 23 starts to rotate in a reverse direction by a spring 26 and the nozzle will return to the original position when the curve 20a reaches the lever 23. After this process, repeated supplies of chips are continued. The final position of the nozzle will be decided either by adjusting the position contacting with the toothed wheel 27 by moving a stopper 27 or by adjusting the length of the coupling rod 30.
