Abstract: PURPOSE:To perform the attitude control of a vehicle by utilizing a hydraulic control and to adapt even for a small sized vehicle by composing a hydraulic circuit by arranging a pressure control valve and other various sorts of valves in the space with the hydraulic pump arranged separately from the hydraulic cylinder arranged on a wheel. CONSTITUTION:When a hydraulic pump 10 is driven, a press oil is pressure accumulated on an accumulator 5 and fed to a gas spring 4 via feeding valve 14 and pressure control valve 2. After completion of the pressure accumulation the press oil of the hydraulic pump 10 is returned to a tank 5 via an unloading valve 16 and the accumulation pressure of an accumulator 8 is held by a check valve 12. When the charging pressure of the gas spring 4 rises, the raised oil pressure is returned to the tank 5 via a relief valve 9. When the attitude of a vehicle is changed at this time, the pressure control valve 2 is actuated so as to maintain the oil pressure equivalent to the reaction force of a hydraulic cylinder 1. The charging pressure of the gas spring 4 is then controlled to check the expansion of the hydraulic cylinder 1.

Filed: 1987-06-18
Abstract: PURPOSE:To remove a field delay difference and to attain smooth image movement by adding a variable delay circuit to a digital video specific effect(DVE) generator, a video synthesizing circuit, a key signal generating circuit and a control circuit for managing size processing. CONSTITUTION:The DVE generator 5 executes size processing based on a key signal or a signal outputted from a control circuit 7 and a signal to which a contraction effect is added is supplied to the video synthesizing circuit 4.

Abstract: PURPOSE:To isolate a collector completely from a substrate, by using the collector and an emitter formable by the same process so as to compose a longitudinal type bipolar transistor. CONSTITUTION:After a p-type diffusion layer 4 is used to obtain isolation regions for NPN and PNP transistors and a CMOSFET, p-type impurities are used to perform ion implantation or the like so as to form a (p) well layer 5 and a collector layer 51 into said two transistors by the same process, n type impurities are used to form a base layer 61 and an (n) well layer 6 in the same process in the collector layer 51 and the (P) channel FET part. After the formation of the base layer 71, a P channel FET p<+> S/D diffusion layer 9 and an N channel FET n<+> S/D diffusion layer 84 are formed in the CMOS part. An emitter layer 91 is formed in the base layer 61 at the bipolar part by the same process as the p<+> S/D diffusion layer 9 is formed, and an emitter layer 81, a collector layer 82 are formed in the base layer 71 by the same process as the n<+> S/D diffusion layer 84 is formed. Hence, a circuit high in its collector potential can be used without necessitating the formation of the collector common to ground.

Title: Cantilever displacement detector
Inventor: ITO SHUICHI
IPC: G01B21/30
Filed: 1992-06-11
Abstract: PURPOSE:To improve the resolution of an optical lever and, at the same time, to reduce the size of the title detector by positioning a bisected light receiving element relatively closely to a mirror on a cantilever so that reflected light from the mirror can fall on the light receiving element. CONSTITUTION:A laser beam emitted from a laser diode 20 is directed to a mirror 32 provided on the upper surface of the free end of a cantilever 30 through the outer peripheral section of an objective lens 12 after the beam is reflected by a half-mirror 16. The laser beam reflected by the mirror 32 is directly directed to a bisected light receiving element 28 positioned near a lens barrel 14. When such a constitution is used, the influence of disturbance, such as air fluctuation caused by the passing laser beam, stray light generated when the laser beam is reflected in an enclosure, etc., is reduced, since the wavelength of the light received by the light receiving element 28 is short, and high-resolution and high-sensitivity displacement detection can be performed, since the laser beam reflected by the surface of a sample 36 returns to the light receiving element 28, does not cause any noise, and can be directly made to impinge on the photoreceptor 28 without using any optical parts.

The charged particle reached a surface of the holder 1 is repelled by charge of a surface of the insulator and is not adhered thereto. Further, because the holder is earthed, safe painting can be carried out.

Title: Detecting circuit of false connection
Inventor: UCHIDA YUKIO
IPC: H04M3/26
Filed: 1983-08-22
Abstract: PURPOSE:To detect the presence or absence of a false connection fault between switch drive lines by monitoring the unbalanced current detecting state of a unbalanced current detecting circuit. CONSTITUTION:In closing a switch S1 first, when a switch drive line DL1 is not false connection with other switch drive lines DL2-DLn, a current flows only to a light emitting diode L1 from an independent power supply V to emit light. If any false connection occurs among the drive lines, the current flows to a light emitting diode L2 as well as the light emitting diode L1 at the same time from the independent power supply V. Thus, the presence or absence of the false contact of the switch drive line DL1 is detected by monitoring the light emitting state of the light emitting diodes L1-Ln in closing the switch S1. Similarly, the presence or a absence of the false connection of the drive lines DL2-DLn is detected by closing alternately the switches S2-Sn.
