Title: Circuit for driving piezoelectric element
Inventor: SUZUKI MASASHI
IPC: H01L41/09
Filed: 1986-11-15
Abstract: PURPOSE:To utilize again electric charge stored at the time of diving, and increase power efficiency, by providing a switching circuit which makes electric charge stored in a piezoelectric element flow inversely from a higher potential side to a lower potential side, and charges the piezoelectric element in the state of inverse polarity. CONSTITUTION:When a charge command signal V2 which is applied to the base of a transistor Tr3 takes a high level, the Tr3 turns on and a voltage is applied to a piezoelectric element 2 from a DC power source 1, which charges it in the direction of A. The piezoelectric element 2 expands and contracts, and this displacement is transferred to a dot printer which is an object to be driven. When the charge command signal V2 takes a low level, the Tr3 turns off. After that, when a trigger voltage V3 is applied to the gate 6a of a thyristor 6, it enters a conduction state. The electric charge stored in the piezoelectric element 2 flows in the direction of X through a reactor 5 and the thyristor 6, and charges up the piezoelectric element 2 in the direction of B.

Title: Control device for turbo-charger
Inventor: HARA SHINJI
IPC: F02B37/10
Filed: 1988-10-28
Abstract: PURPOSE:To lighten an unnecessary load on a battery and to secure traveling safety during going back of a car in a turbo-charger having an electric mechanism for superchargedly energizing by providing a control means for stopping the superchargedly energizing executed by the electric mechanism during going back and stopping of a vessel. CONSTITUTION:When a driver presses down an accelerator pedal 3, a potentiometer 31 outputs a signal corresponding with the pressed down amount of the accelerator, and the signal is inputted into a control unit 9. In the case where, when it is judged that accelerating operation has been performed in the control unit 9, a brake is not in its functioning, and a clutch is in a connected state, and moreover shift is at the position of advance, the signal is outputted to an electric motor 24 to make the turbo-charger 2 poweringly operate. Thus a compressor 21 is encouraged in its supercharging action. In addition to that, when even any one of the above-mentioned three conditions can not be realized, the electric motor 24 is not driven, and the supercharging action to be performed by the compressor 21 is done by only torque produced through exhaust generated by a turbine.

Title: Water bath device for vending machine
Inventor: MINAKANE KEIICHI
IPC: G07F9/10
Filed: 1989-10-20
Abstract: PURPOSE:To avoid the occurrence of overall freezing of a water bath by detecting the expiration of a timer means to stop the operation of a compressor at the time when an ice bank cannot be detected because of the occurrence of abnormality in an ice detecting electrode group. CONSTITUTION:The timer means is provided which consists of nor only an ice detecting electrode group 7 but also a counter 11 and a step where it is discriminated whether the counted value of this counter 11 reaches a prescribed value or not. Consequently, the operation of a compressor 1 is forcibly stopped at the time of detecting the expiration of the timer means though an ice bank cannot be detected because of the occurrence of abnormality in the ice detecting electrode group 7. Thus, overall freezing due to excessive cooling is avoided to stably supply cooled water to a cup 5.

Title: Operation unit for zoom lens
Inventor: HIGAKI TOSHINORI
IPC: H04N5/232
Filed: 1994-10-11
Abstract: PURPOSE: To extend a term for replenishing lubricant by automatically supplying the lubricant at the inside of a hollow chamber to an interstice between a sliding tube and a sliding member by difference in pressure between plural oil holes. CONSTITUTION: When a zooming operation is not performed, the lubricant at the inside of the hollow chambers 29 and 30 of the sliding member 6 does not flow out to the outside of the sliding member 6, so that the natural decrease of the lubricant is small. On the other hand, when the zooming operation is performed and the pushing/pulling of an operation bar is performed at high speed, the difference in air pressure is generated between the fitted part made by the sliding member 6 and the sliding tube 10 and the straight groove 10a of the sliding tube 10 when the sliding member 6 moves in an axial direction, so that outside air enters the hollow chambers 29 and 30 from the oil member 6b of the sliding member 6 at the straight groove 10a and the lubricant flows out to the fitted part made by the sliding member 6 and the sliding tube 10 from the oil hole 6a of the sliding member 6.  Thus, a smooth zooming operation and a smooth focusing operation are performed.

At the time of picture recording, a switch 19 is changed over to the LUT 17 and the input picture data is corrected and inputted to a laser driving part 20. Then, the relation between the gradation of the picture data and the average potential is held constant.

Title: Lead storage battery
Inventor: INOUE TOSHIHIRO
IPC: H01M10/60
Filed: 1986-11-17
Abstract: PURPOSE:To improve the energy density, miniaturize the size, and lighten the weight of a lead storage batter by adding TiO or TiO2 to positive electrode active materials. CONSTITUTION:Titanium oxide or titanium dioxide is added to lead oxide used as active materials. At that time, an added quantity of the titanium oxide or the titanium dioxide is 0.3-5 weight % of the lead oxide quantity. If the added quantity of TiO exceeds 5 wt.%, the effect of adding is lost and the capacity decreases considerably. This enables a discharge reaction of a positive electrode to be promoted and an utilization factor of active materials to be improved.

Title: Manufacture of single crystal alloy thin film
Inventor: KONAGAI MAKOTO
IPC: H01L31/04
Filed: 1987-10-30
Abstract: PURPOSE:To contrive to form a single crystal germanium alloy thin film into a large area and also to improve in manufacturing speed of the thin film by a method wherein the mixed gas, in which a specific quantity of hydrogen for silane, germanium compound and fluorosilane is coexisted, is decomposed by electrical discharge at the substrate temperature of 300 deg.C or below. CONSTITUTION:When the mixed gas consisting of silane, a germanium compound and fluorosilane is going to be decomposed by electrical discharge, the mixed gas having the coexisting hydrogen of two or more mol times for silane, a germanium compound and fluorosilane is formed, and the mixed gas is decomposed by electrical discharge. As the single crystal alloy thin film has the tendency that it is liable to be formed in the region having an abandant adding quantity of hydrogen, but the adding of too much quantity of hydrogen is undesirable, because it decreases the growing speed of the single crystal alloy thin film, and the quantity of addition of the hydrogen of 30 times or less of the value of the flow ratio of raw gas supplied to a thin film forming device is considered sufficient. Also, the ingredient ratio of (fluorosilane/(silane+germanium compound)) is 0.5-50. The value of the ratio of germanium compound/silane is to be within the range of 0.01-0.2 in the case of the silicon-germanium alloy of Ge/Si=1/1.

Abstract: PURPOSE:To decrease exposure dose of workers by providing a water seal part above an upper tieplate to seal water for radiation shield and decreasing radiation from a filter element. CONSTITUTION:The ceramic filter 1 contained in a cylindrical body 6 is supported at the bottom with a lower tieplate 18 and at the top with an upper tieplate 9. And above the tieplate 9, a water seal part 7 is provided to shield radiation from the filter 1.

In such a case, water is sealed in the water seal part 7 before the work for removing the filter 1 out of the floor 8a to shield the radiation from the filter 1. In the other direction than the upward, radiation does not reach workers directly owing to the floor 8a. Therefore, the exposure doses of workers is decreased.
