Title: Vapor growth device
Inventor: KAWAI HIROHARU
IPC: H01L21/203
Filed: 1993-05-31
Abstract: PURPOSE:To protect a susceptor from deposits during vapor phase epitaxy in a reaction chamber by allowing gas, containing no source of deposit, to flow along the chamber wall opposite the susceptor. CONSTITUTION:Gas which does not contain the material is permitted to flow in a vapor growth reaction chamber 2, especially to a base 1, namely on a wall that faces the arranging body 15 for the base. As for the gas which does not contain the material, H2 gas or inactive gas N2 or Ar is used and the gas is permitted to flow in an arrow (a) direction, which is almost same as an arrow (b) direction in which the material gas is supplied to the vapor growth reaction chamber 2. Thus, the inner wall facing a wafer 1 in the vapor growth reaction chamber 2 is protected from deposits, which may be blacked and delivered onto the wafer by vibrations or turbulent flows of the material gas, and stable vapor growth is performed.

IPC: F16D27/112
Filed: 1979-10-08
Abstract: PURPOSE: To reduce leaked magnetic flux from an electromagnetic clutch and mechanically stabilize the clutch even at high temperatures, by forming grooves in the entire inner peripheral face of an outer disc and the entire outer peripheral face of  an inner disc plate and inserting into the thus-formed grooves ring-shaped binder  made of a nonmagnetic material.  
     CONSTITUTION: Grooves 221b, 222b having rugged parts 221d, 222d respectively at the bottoms thereof are formed in their corresponding disc plates 221, 222. Into these grooves 221b, 222b, substantially ring-shaped binder materials 223 made of a nonmagnetic material are inserted. Then, the disc plates 221 and 222 are pressed to each other to cause a plastic flow of the binder materials 223, thereby mechanically fixing the disc plates 221, 222 together. Since the binder material is made of a nonmagnetic material, leaked magnetic flux would be reduced. On the other hand, since each groove bottom is roughened, a sufficient mechanical strength can be obtained against revolution torques and the clutch can be mechanically stabilized even at high temperatures.

Title: Solid electrolytic tube of sodium-sulfur battery
Inventor: SUGIMOTO KOJI
IPC: H01M10/39
Filed: 1988-05-27
Abstract: PURPOSE:To depress the absorption of moisture and improve working properties such as preservation, transportation and assembly by providing a beta-alumina layer against the surface of a solid electrolytic tube body made of beta''-alumina. CONSTITUTION:In a solid electrolytic tube 5, a thin beta-alumina layer 5b having a limited sodium content which is not so sensitive to moisture is formed against the surface of a bottomed cylindrical solid electrolytic tube body 5a made of beta''-alumina by heating only the surface thereof by a gas burner. beta-alumina has a high electric resistance, compared with beta''-alumina. However, the formation of the thin beta-alumina layer on the surface of the body 5a composed of beta''-alumina enables a reduction in influence of water and also provides those having almost the same electric resistance. Hence, even if the tube 5 is preserved in the atmosphere for a long time, the absorption of moisture is depressed, and the sodium ion conductivity is properly maintained. Thus, the reduction in performance of the battery can be prevented.

Title: Vehicle speed control device of vehicle with continuously variable transmission
Inventor: ASHIZAWA HIROYUKI
IPC: B60W10/06
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To stably control the vehicle speed even in the state where the engine torque is saturated in an uphill road or downhill road by changing the time contact of a filter processing applied to the target driving force and actual vehicle speed by a disturbance estimating means, when the saturated state of the engine torque is detected by an engine torque saturation detecting means. SOLUTION: A disturbance estimating device can precisely estimate a disturbance such as traveling resistance on the basis of the difference between the output of a model to be controlled and the output of an actual subject to be controlled. The cutoff frequency (time constant) of a low pass filter in a compensator is set according to saturation or non-saturation of engine torque. The engine torque of an engine 10 can be regulated by controlling the intake air by a throttle actuator, the fuel injection by an injector and the ignition timing by an ignition plug. The change gear ratio of a belt type continuously variable transmission 11 can be regulated in non-stage by varying the radiuses of a primary pulley and a secondary pulley by a hydraulic mechanism.
