Title: Fuel injection quantity controller for internal combustion engine
Inventor: KAWAMURA TAMIMASA
IPC: F02D41/00
Filed: 1986-02-28
Abstract: PURPOSE:To secure the smooth drivability by installing a reduction means for gradually reducing the calculation value of the standard fuel injection quantity in a certain rate when the start of reduction of the calculation value is judged, thus preventing the variation of revolution immediately after acceleration. CONSTITUTION:Each signal of a lap type air flow meter 15 and a crank angle sensor 17 is input into a control unit 30. The fundamental injection quantity is calculated in the control unit 30, and when the start of reduction of the calculation value is judged, the calculation value is gradually reduced in a certain rate, having the calculation value on start of reduction as initial value, independently of the signal of the air flow meter 15. A fuel injection valve 19 is opened according to the calculation value of the control unit 30. Thus, the smooth drivability can be secured by preventing the variation of revolution immediately after acceleration.

Title: Semiconductor integrated circuit
Inventor: NISHIZAWA JIYUNICHI
IPC: H01L29/73
Filed: 1981-03-23
Abstract: PURPOSE:To enable to operate a semiconductor integrated circuit at high speed by employing a bipolar transistor being placed under a state that base regions are pinched off approximately, for logical gates of various kinds. CONSTITUTION:An N<+> region 1, an N<-> region 2, P regions 4, 5 and N<+> regions 3, 3' are each the emitters, bases and collectors of an inverted bipolar transistor BPT, and P regions 6, N regions 7, 8 and P regions 9, 9' are each emitters, bases and collectors. Since the base regions 5 existing among the emitters and collectors of the BPT are formed by diffusion from the regions 4, the thickness is thin, the density of the impurities is low and they are brought to a condition that is pinched off approximately. When the BPT designed in this manner is employed for logical gates of various kinds, a small number carrier accumulating effect is slight, and capacity among electrodes is small, thus obtaning a semiconductor IC which can work at high speed.

Filed: 1980-04-02
Abstract: PURPOSE:To simplify the manufacture by reducing etching processes and in addition, to prevent the performance from being fallen by obtaining the photoelectric conversion element without a process to directly etch a photoelectric conversion layer. CONSTITUTION:In2O3 is evaporated on a soda glass plate 1 to form a desired electrode pattern. Al 3 is layer-built to be applied with a resist mask 5, and the Al is etched to form a groove 6. Then, a layer 8 large and a layer 9 small in a band width are layer-built by evaporation in the combination of CdS-CdTe. As2Se3 10 is formed on the layers 8, 9 to further improve a photoelectric characteristic. Then, the Al 3 is etched to make an Al electrodes 11 be attached. With this construction, the manufacturing process is simplified because the laminated layers are not individually etched, and since the photoelectric conversion layer is layer-built by an evaporating method, a long size or a large area can easily be made. In addition, since a chemical etching process is not directly applied to the photoelectric conversion layers. an etching liquid is contaminated and the excellent characteristic can be obtained.

Title: Taste control device in successive rice boiler
Inventor: TACHIBANA TOSHIHIKO
IPC: A23L7/10
Filed: 1988-02-26
Abstract: PURPOSE:To improve a taste by detecting the taste of a grain to be boiled up and adjusting a moisture adding quantity or a pressurizing quantity to the grain based on the detection result. CONSTITUTION:The taste of the grain such as a rice to be boiled up is detected by a texturometer 32 which is a taste detecting means. The texturometer 32 outputs a detecting waveform according to the hardness and viscosity of the grain which are elements to decide the taste of the grain to be boiled up. A microcomputer 41 obtains the hardness and viscosity of the grain from the detecting waveform. When the hardness of the grain is abnormal, the opening degree of a feed water control valve 38 which is a feed water control means is adjusted, the adding quantity of a moisture to the grain is adjusted, and the hardness of the grain is changed. On the other hand, when the viscosity of the grain is abnormal, the open and close of a pressure control valve 18 and a pressure reduction control valve 19 which are pressure control means are adjusted, the pressurizing quantity to the grain is adjusted, and the viscosity of the grain is changed. Consequently, by the controls, the taste of the grain to be boiled up can be maintained prescribed.

Title: Positioning stopper in conveyor
Inventor: KURITA YUTAKA
IPC: B65G54/00
Filed: 1986-02-28
Abstract: PURPOSE:To aim at the prompt stop of a truck, by subtracting such a voltage (current) proportionate to a travel speed from the specified voltage (current) at a period of time when the conveying truck comes nearer to a stopping position but totaling them at a period of time when the truck becomes far off, feeding the primary side of an electromagnet, and generating damping force there. CONSTITUTION:At a period of time when a conveying truck 1 comes nearer to a stopping position 2, restoring force (f) corresponding to voltage V0-K1¦v¦ acts on the truck 1, and at a period of time when the truck becomes far off, restoring force (f) corresponding to voltage V0+K1¦v¦ acts on the truck 1. That is to say, when the truck 1 heads for the stopping position 2, exciting voltage of an electromagnet 6 is held down to low, but when it gets away from it, the exciting voltage of the electromagnet 6 is suddenly increased, whereby such force that pulls the truck 1 back strongly acts on the truck. Therefore, the restoring force (f) acting on the truck 1 varies in an arrow direction on a hysteresis curve with a variation in displacement X of the truck 1 so that energy equivalent to a hysteresis loop area is consumed by the electromagnet 6 and a controller 11 or the like, dispersed and lost to some extent, and the displacement X and the restoring force (f) are focused to zero while describing the hysteresis loop, thus the truck 1 is promptly stopped.
