Title: Fuel supply controller of internal-combustion engine
Inventor: TAKIZAWA SATORU
IPC: F02D41/08
Filed: 1982-04-06
Abstract: PURPOSE:To improve operative stability at idle operation, by calculating a basic fuel supply amount from the speed at the preceding time of fuel injection and the speed at the present point of time. CONSTITUTION:In accordance with a signal from an idle switch when a throttle valve is fully closed, a fuel injection amount is obtained in accordance with a speed obtained from an expression No+alpha(N-No). Here No is an engine speed used at the preceding time of fuel injection and N is an engine speed at the present point of time. alpha is, for instance, 0-2.0. When the engine speed is change, fuel is never supplied in a follow-up state to a change of the engine speed, and adjustment of a supply amount is controlled so as to be delayed by the amount of the constant alpha and relaxed with respect to the change of the speed. In this way, operative stability is improved at idle time.

Title: Charging device for electrophotographic copiers
Inventor: TSUTSUMI TAKASHI
IPC: G03G15/02
Filed: 1978-05-18
Abstract: PURPOSE: To prevent the occurrence of jam, electric shock, short-circuiting, etc. by letting the  charging rollers convered with dielectric also serve as photosensitive feed rollers.   
     CONSTITUTION: Charging rollrs 1, 2 covered with dielectric are opposedly disposed and charging  slide brushes 3, 4 are slide-contacted respectrively thereto and are connected to power source E,  E'. Then photosensitive paper P is fed by passing between the charging rollers 1, 2. This causes  the dielectric surfaces to be charged positive and negative owing to the potential differences from  the cores of the charging rollers 1, 2, thus when photosensitive paper P is fed by passing between  the both rollers 1, 2, the negative charges are injected onto the photosensitive material layer of the  front thereof and positive charges to the back thereof. The potentials of the dielectric surfaces are  then divided in accordance with Paschen's law and the electrostatic capacity ratios of the photosensitive paper P and dielectric, whereby the photosensitive paper P is charged. Hence, the charging rollers 1, 2 also serve as photosensitive paper feed rollers and this lets the photosensitive paper  P be stably fed and the occurrence of jam be prevented. In addition, there is no danger for electric  shock, shorting, etc. because high voltage is not directly applied to the photosensitive paper P.

Title: Semiconductor device
Inventor: YOSHIKAWA TOSHIBUMI
IPC: H01L23/60
Filed: 1983-04-01
Abstract: PURPOSE:To obtain the titled device whose static capacitance is small and static withstand voltage is large, and which has static shielding effect on the charges from outside by arranging a metallic conductor on an oxide insulation film in the periphery of the upper surface part of an ion implantation resistor by excluding said part, in a bi-polar integrated circuit. CONSTITUTION:By excluding the upper surface part of the ion implantation part (P<+> part 5 serving as a resistor), only its periphery is shielded with the metallic conductor (Al) 6. Thereby, the capacitance reduces to one-several numbers, and the static withstand voltage multiplies by several times. The capacitance and the static withstand voltage are determined by the ratio of the thickness of the oxide insulation film, but, in this case, determined by the part 2 (5,000-10,000Angstrom ) of a thicker film. The width (d) in removing the metallic conductor 6 is approx. 10mu, and accordingly the static shielding effect can be made so as to hardly vary with the charges from outside.
