Title: Driving method for active matrix liquid crystal element
Inventor: KANEKO SHUZO
IPC: G09G3/36
Filed: 1990-03-22
Abstract: PURPOSE:To obtain the display element requiring high-fineness driving by impressing a grounding signal upon lapse of a prescribed period of time after a recording signal voltage is impressed. CONSTITUTION:The open characteristic of both sides of a cell for holding the recording voltage signal Vx impressed to a picture element (liquid crystal) as a recoding voltage Vw is maintained for the time required for the change in the optical state of the picture element and thereafter, both ends of the cell are once switched ideally to an earth or ground voltage (voltage=0), by which the long impression of the recording voltage Vw with respect to a reset voltage Vr is obviated and a DC offset is decreased. The reset voltage Vr and recording voltage Vw of different polarities are impressed for nearly the same period of time, by which the recording state is fixed and since the memory characteristic of the liquid crystal itself is utilized for holding the optical state between one frame, the deterioration in the display quality by the DC offset is drastically lessened. The formation of a fine-fitness direct viewing type flat display or projection television is possible in this way.

Title: Supercharging pressure controller in exhaust turbosupercharging type internal-combustion engine
Inventor: HASEGAWA KUNIO
IPC: F02B37/12
Filed: 1983-04-19
Abstract: PURPOSE:To make supercharging pressure at acceleration controllable into a smooth stable characteristic curve, by constituting two pressure transmission passages leading to a waste gate valve installed in a passage, which bypasses an exhaust turbine of a supercharger, with a delay device and a pressure on-off valve installed jointly. CONSTITUTION:In time of quick acceleration in an engine which therefore suddenly opens a throttle valve 9, supercharging pressure goes up suddenly but a suddent rise in this pressure is fittingly delayed for a proper time long with a delay device 22 inside a first pressure transmission passage 19 and transmitted to a pressure chamber 18 of a waste gate valve 15. And, when the supercharging pressure reaches to a range of acceleration setting supercharging pressure P1 of a pressure on-off valve 24 inside a second pressure transmission passage 23, the said valve 24 opens whereby the supercharging pressure is transmitted to the pressure chamber 18 by way of the passage 23, thus the waste gate valve 15 is opened. At this time, the pressure on-off valve 24 is gradually opened because air inside its atmospheric interconnecting chamber 26 is gradually leaked via an auxiliary delay device 32 so that sudden opening in the waste gate valve 15 is being prevented.

Title: Apparatus for judging corrosion resistance of coating film
Inventor: SUZUKI MASAYUKI
IPC: G01N17/00
Filed: 1982-04-28
Abstract: PURPOSE:To carry out accurate measurement and to make it possible to judge the initial deterioration of a coating film, by a method wherein a charge pulse is imparted to a metal test piece coated with a coating film from a capacitor having predetermined quantity of electricity accumulated therein and the change with the elapse of time in the potential of electrified charge is used as the change in the difference of potential with reference potential to carry out measurement. CONSTITUTION:When a carbon steel coated with a minium paint in a thickness of 100mum is used as a metal test piece 1 while a platinum plate is used as an opposed electrode 2 and saturated calomel as a reference electrode 3 to be immersed in a saline solution 4 with 3% concn. at a room temp. and double layer capacity CD and polarization resistance RP are measured, the measured values directly after immersion are unstable and measurement is impossible. After a day is elapsed, CD is 0.15F/cm<2> while RP is 3X10<9>OMEGAcm<2> and the reproducibility of indicating potential before and after measurement is good. After three months are elapsed after immersion, CD is 1.3F/cm<2> while RP is 3X10<7>OMEGAcm<2> and, thereafter, CD is rapidly increased while RP is rapidly reduced to ascertain corrosion under the coating film. As is apparent from the foregoing, RP and CD are made stable directly after measurement is initiated to enable measurement.

Title: Driving device for scanning type optical system
Inventor: KITABAYASHI JIYUNICHI
IPC: G03B27/50
Filed: 1980-05-27
Abstract: PURPOSE:To scan an optical system at a constant speed and to return it at a high speed, by driving the optical system in one direction through a cam device and by returning the optical system by the righting moment of a spring in an independently provided spring expanding device. CONSTITUTION:When an optical system unit 1 at a scan starting position, electric motors 10 and 25 are driven under a command. When a plate cam 7 is rotated clockwise (as shown by an arrow) by the electric motor 10, the optical system unit 1 moves and scans to right through a lever 13. Since a spring 16 is weakened at this time, its scanning speed is constant. On the other hand, as the electric motor 25 drives the driven pulley of a clutch device 20 counterclockwise, a hook member 18 moves to right against the strength of a spring 17. At a scan ending point, the electric motors 10 and 25 stop and the clutch device 20 is turned off, thereby returning the optical unit 1 engaged with the hook member 18 at a high speed by the strong retaining strength of the tension spring 17.
