Filed: 1981-03-09
Abstract: PURPOSE:To obtain a light and compact ceramic turbo-charger for an internal combustion engine by selecting the material for a shaft to be equalized in the total thermal expansion with a turbine casing and others at any high temperature. CONSTITUTION:A shaft 7 and bearings 5 and 6 are constructed of heat-resisting and wear-resisting materials such as ceramic and the like. Exhaust gas is spirally introduced from an inlet 1A for operating a turbine 9, and exhausted from a center part 1B, while air is sucked from a center part 2B, compressed by an impeller 8, and sent out from 2A. As this shaft 7 is thermally expanded, the coefficient of the thermal expansion of the shaft 7 is selected to be equalized with the total thermal expasion of a supporting bearing 5, a spacer 4, and a casing 1. Meanwhile, for preventing the leakage of gas, a disk-shaped labyrinth 10 is fitted to the shaft 7 and caught by a labyrinth packing 15 made of carbon, and between them, the compressed air from the gap between a casing 2 and the shaft 7 is introduced for sealing by pressure. Besides, the intermediate part of the shaft 7 is float-supported by ceramic balls 11.

Abstract: PURPOSE:To improve withstand voltage between a gate and a source by forming a dummy gate jointly using isotropic and anisotropic etching and selective ion implantation using this dummy gate as a mask. CONSTITUTION:Using a photoresist 4 as a gate mask, a part of a silicon dioxide film 3 is obliquely processed by isotropic etching and the remaining part is vertically processed by anisotropic etching. Then, the processed silicon dioxide film 3 is used as a dummy gate to perform selective ion implantation for forming an n<+> conductive layer 5. The photoresist 4 is uniformly etched until a part of the dummy gate 3 is exposed for etching-off with a solution of a fluoric acid system in order to make the photoresist 4 up of an undercut construction. A gate metal 6 forming Schottky junction with an n-type active layer 2 is vacuum-evaporated on the under-cut part and the photoresist 4. Thereby, the distance between a gate metal 6 and the n<+> conductive layer 5 can be enlarged for heightning withstand voltage between the gate and a source.

Title: Driving method of liquid crystal optical element
Inventor: HIRAI YOSHINORI
IPC: G09G3/18
Filed: 1993-01-29
Abstract: PURPOSE:To switch a liquid crystal optical shutter, which is made large in area by using a liquid crystal solid compound, at a high speed for a large-area panel by adjusting the timing of the impression of a driving voltage pulse between confronting electrodes. CONSTITUTION:This driving method uses a voltage waveform that accelerates the accumulation of electric charges in electrodes between which the liquid crystal solid compound is sandwiched at the time of impressing voltage or a voltage waveform which accelerates the releasing (removal) of electric charges from the electrodes at the time of voltage removal so as to eliminate a factor of impedance to response. Namely, a voltage Von+Va which is higher than a normal driving voltage Von is impressed for Ya ms at the time of impressing voltage to accelerate the accumulation of electric charges. Further, when the voltage is removed, a voltage -Vb which is opposite in sign from the On voltage right before it is impressed for Yb ms between lead-out electrodes. Consequently, delay due to the accumulation or releasing of electric charges is reduced and the response of the liquid crystal optical shutter can be approximated to the original characteristic limit that the liquid crystal solid compound has.

Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To prevent the external appearance of a product from deteriorating and the fixation between a mat and the pressurizing surface of a top surface plate from occurring by a method wherein this clamping device consists of a clamping means between the top surface plate and a bottom surface plate under the state that a fiber reinforced synthetic resin layer (an FRP layer) is interposed between the pressurizing surface of the top surface plate and the mat. SOLUTION: In order to manufacture an inorganic plate, a semi-drying method or a drying method for curing and hardening mats 20 under a clamped state with a clamping device 11 is applied by forming each mat by scattering a stock mixture mainly made of a cement and a wooden reinforcing material such as wooden piece or the like on a conveying plate 19.

The water temperature is detected by the heat exchanger thermistor 37. In the case where the temperature detected is not higher than the prescribed temperature, steam produced together with combustion is cooled and condensed by the water in the heat exchanger 32 to be drain. The controlling means 40 closes the electromagnetic valves 21, 22 and the air blower 12 is actuated to exhaust drain.
