Title: Manufacture of oscillatory-type transducer
Inventor: ISHIGURO HIROSHI
IPC: H01L29/84
Filed: 1992-01-28
Abstract: PURPOSE:To improve electric characteristics and to make it possible to manufacture an oscillatory-type transducer having the excellent external-noise resisting characteristic by constituting oscillatory beam comprising silicon single-crystal material, and constituting a substrate and a vacuum chamber so as to surround the oscillatory beam and forming a shell so as to maintain a gap around the oscillatory beam. CONSTITUTION:A silicon oxide film 209 is formed on a substrate of silicon single crystal. A recess part 203, which forms the substrate side of a vacuum chamber is formed in the substrate corresponding to a required place 202 by etching. Then, first-sixth epitaxial layers are formed by selective epitaxial growth. Finally, a polysilicon layer 213 is formed on the surface of the ground film 209, and the etching injection port is closed. At the same time, seventh and eight epitaxially grown layers 214 and 215 comprising silicon single crystal are formed on the outer surfaces of the fifth and sixth epitaxial grown layers 211 and 212 and the outer surface of the substrate. The polysilicon layer 213 is not in contact with the P layer of the shell. The leaking current of a PN junction become small, and the abnormal signal of the oscillatory beam caused by external noises is prevented.

Abstract: PURPOSE:To obtain a kick type starting device suitable to make an engine small-sized and lightweight and capable of reducing the engine width by providing a clutch claw and a small gear movably and rotatably in the crank shaft direction and integrally with a cover holding shaft. CONSTITUTION:A clutch claw 5 and a helical-teeth small gear 5b adjacent to it are integrally formed on a shaft 5a.

IPC: G11B3/58
Filed: 1979-02-07
Abstract: PURPOSE: To secure elimination of a large amount of dust by giving the contact in sequence between the flocked hair free from the dust and the record disc.  
     CONSTITUTION: The current is supplied to motor 2 along with operation of the air compressor, and then cleaner body 3 is made to touch the surface of record disc 20 which is turning. Thus the dust sticking onto the disc sticks to the flocked hair of cleaner 3, and the dust is carried up to the part where dust cleaning plate 10. Eccentric cam 13 turns by the rotation of motor 2, and thus arm 11 vibrates to cause the vibration of axle 9 and plate 10. As a result, the dust sticking to cleaner body 3 is thrown off to fly into the air. On the other hand, the air within barrel 5 is sucked by the function of the air compressor, and thus the dust flying into the air is sucked through suction hole 6 and then exhausted. The flocked hair of cleaned cleaner body 3 with the dust eliminated touches again disc 20 to adsorb the new dust.

Title: Driving circuit of liquid crystal display device

IPC: G02F1/133
Filed: 1990-01-24
Abstract: PURPOSE:To enable fast operation and obtain high definition by making the operating voltage range of each signal electrode driving means different from the operating voltage ranges of other driving means. CONSTITUTION:When a source electrode 110 is driven, voltages V1 and V2 are supplied by a 1st source driver D12a and voltages V3 and V4 are supplied by a 2nd source driver D22b. When the voltage V1 or V2 needs to be supplied to the electrode 110, a controller C3 holds a control signal FD at 'high' level to place the output of the driver D22b in a high-impedance state. When the voltages V3 and V4 are supplied to the electrode 110, the C3 holds the signal FD at 'low' level to place the output of the driver D12a in a high-impedance state. Which of the voltages V1 and V2 is outputted from the driver D12a is determined according to an external video signal. The driver D22b is the same. Consequently, the high speed operation of the driving means becomes possible to make the definition of a display unit high.

Title: Led driving circuit
Inventor: AOKI KANJI
IPC: H01L33/00
Filed: 1989-01-24
Abstract: PURPOSE:To enable temperature characteristics of light amount of an LED to be corrected sufficiently by means of an LED driving circuit, by providing the diode with temperature characteristics suitable for correcting temperature characteristics of mobility of an output FET and temperature characteristics relating to efficiency of light emission of the LED. CONSTITUTION:An effective gate bias of an output FET is amplified by an amplification circuit 8 to determine an effective gate bias value. If the effective gate bias value is low, the output FET must be large in size. If the effective gate bias value is high, on the contrary, the output will have undesirable constant current characteristics. Accordingly, the effective gate bias value must be selected properly. Output of a reference voltage source depending on difference in work function is once resistance-divided and each divided potential is divided by the resistance and the diode. In this manner, variance in temperature characteristics of output current can be minimized even if difference is caused in temperature characteristics of the resistances and diodes among various productions.
