Title: Electronic engine control system
Inventor: MAEDA HARUHIKO
IPC: G01F1/68
Filed: 1989-03-20
Abstract: PURPOSE:To reduce measuring errors by providing a suction pipe having at least two or more air paths on the downstream side of a hot wire type air flowmeter. CONSTITUTION:Suction pipes 7 and 10 in which an air path is formed to an engine 8 from the downstream side of a hot wire type air flowmeter are provided with a plurality of air paths 6 and 6a. The suction pipes 7 and 10 are given a difference at least equivalent to a half of a cycle of an air pulsation so that air pulsations passing through the respective pipes are buffered at a converging point of the suction pipes. As a result, at the converging point of the suction pipes 7 and 10, the top of an amplitude of a pulsation is transmitted from one suction pipe while the bottom of an amplitude of a pulsation is transmitted from the other suction pipe to cancel each other. The sectional areas of the suction pipes 7 and 10 are the same so that pulsations transmitted from the suction pipes 7 and 10 are the equal in intensity. Thus, pulsation of a suction can be relaxed on the downstream side of the flowmeter 4 and an injection level of a fuel is controlled by an output signal of the flowmeter 4 as one of sensors composing a system.

Title: Purge control method for name cache mechanism in pass name retrieval
IPC: G06F12/00
Filed: 1992-03-25
Abstract: PURPOSE:To accelerate the retrieval of a pass name and to suppress the reduction of professing efficiency as the whole system by performing the purge of a name cache table setting a range designated selectively (for example, device name, filing system) as a unit. CONSTITUTION:Each name cache table 10 holds not only a file managing table 20a in accordance with file name 11 but the device name 12 as the identifier of the device in which the file exists. For example, when the purge of name cache 1 occurs due to the removal of a hard disk device HD2, the device name 12 of the table 10 is compared with the device name HD2 of a removed filing system, and only a coincidental table 10 is purged. Thereby, no access to a real input/output device occurs in the pass name retrieval of the file controlled by a following HD1, and the retrieval is completed only by performing scan on the name cache 1.

Title: Image forming method and device
Inventor: SATO KAZUHIKO
IPC: G03G15/08
Filed: 1995-03-02
Abstract: PURPOSE: To prevent image deviation from occurring by specifying surface pressure by the pressing force of a transfer roller to a photoreceptor drum. CONSTITUTION: A transfer material is allowed to pass between an image carrier having the superposed toner image of two or more colors and a transfer means, and the toner image is electrostatically transferred on the transfer material altogether while pressing the transfer means so that the surface pressure by the pressing force exerted on the image carrier is <=1000g/cm<2> . In order to form the image at a higher speed, the transfer roller must come into press-contact with and be separated from the photoreceptor drum in the midst of writing at least at the time of consecutive printing, and it must come into press-contact with the photoreceptor drum in the midst of developing even in the case of one print.  In such press-contact and separation, when the surface pressure by the pressing force is 800g/cm<2> , for example, the variation of the circumferential speed of the photoreceptor drum to the rotational angle position of the photoreceptor drum is small and does not influence the image. However, when the surface pressure is 1500g/cm<2> , the variation is larger and if the transfer roller comes into press-contact with or is separated from the photoreceptor drum in the midst of writing by an optical system and in the midst of developing, the deviation in the image is generated.

Title: Compound semiconductor device and method of manufacturing the same
Inventor: MINAMI SHIYUNSUKE
IPC: H01L21/335
Filed: 1990-03-15
Abstract: PURPOSE: To make it possible to manufacture a compound semiconductor element of a new structure wherein cap layers are provided in such a way that they are brought into contact directly with a two-dimensional electronic layer and the source resistance of an HEMT is decreased. CONSTITUTION: Source and drain electrodes 21 and 23 are each formed on the upper part of each N<-> GaAs cap layer 19 and a control electrode, that is, a gate electrode 25, which Schottky contacts with an N<-> AlGaAs source layer 17, is formed on the exposed surface of this source layer 17. In a high electron mobility transistor (MEMT) of this structure, when a voltage is applied to the electrode 25, a donor in the layer 17 is ionized to generate two-dimensional electrons and these generated two-dimensional electrons move at high speed without scattering due to impurities through a channel, which is formed in the surface of an N<-> GaAs buffer layer 13 by a voltage difference between the electrodes 21 and 23. Thereby, a source resistance of the HEMT is decreased and the enhancement of the transfer conductance of the HEMT is contrived.

Title: Semiconductor memory device
Inventor: ISHIKAWA OSAMU
IPC: H01L27/108
Filed: 1984-04-04
Abstract: PURPOSE:To contrive the increase in capacitance per unit area by a method wherein a P type Si substrate immediately under the electrode of an MOS capacitor is provided with the first N-layer, a P-layer connected to the substrate, and the second N-layer continuous to the first N-layer. CONSTITUTION:After the N-layers 9 and 12 are formed in a P type Si substrate 1 by the same diffusion, the P-layer 10 is provided selectively at the intermediate section by ion implantation. Therefore, a capacitor made by P-N junction is formed in the substrate in addition to the MOS capacitor on the surface, and the amount of charge accumulation increases. For example, when the oxide film under the capacitor electrode 5 is 250Angstrom , the MOS capacitance value is 4.14X10<-7>F/ cm<2>, whereas the P-N junction capacitance value is corresponding to about 2X 10<17>F/cm<2> when the concentration of the substrate 1 is 4X10<17>/cm<2>, resulting in the number of the P-N junction planes by two; therefore, this value becomes about twice of the case of utilizing only the surface. Accordingly, the integration can be increased by reducing the element dimension in order to obtain the same capacitance value.
