Title: Semiconductor vapor growth device
Inventor: SASAOKA CHIAKI
IPC: H01L21/205
Filed: 1987-07-03
Abstract: PURPOSE:To make a raw gas exchangeable steeply, by providing a raw gas supply tube with a pipeline switching valve and making an exhaust pipe branch to suck the raw gas inside the raw gas supply pipe and a reaction tube when the valve is opened. CONSTITUTION:When a valve 105 is closed, a raw gas is introduced into a reaction tube 104 via a raw gas supply pipe 106, a flow rate regulator 102, and a raw gas supply pipe 107. When the valve 105 is opened, the raw gas flows to an exhaust pipe 103 via a flow rate regulator 101. However, since the flow rate in the flow rate regulator 101 is larger than that of the flow rate regulator 102, one part of the gas in the reaction tube 104 also passes through the raw gas supply tube 107 and flows to the exhaust pipe 103. Accordingly hot only the raw gas flowing through the raw gas supply pipe 106 but also the raw gas remaining in the raw gas supply pipe 107 is exhausted through the exhaust pipe 103 to rapidly interrupt the supply of the raw gas.

Abstract: PURPOSE:To aim at miniaturization and lightening through preparing a design rational to the mechanical load by setting the average shell diameter of each lightning protection insulator in such a manner that it is the more small the more far from the column- substance side, and then setting the creepage distance thereof in such a manner that it is the more short the more far from the column-substance side. CONSTITUTION:The current limiting element structure, such as the total length L1-L3 and the number of pieces, of each of the lightning protection insulators 8A-8C is made identical to each other, and then, the aerial effective insulating length thereof is also made almost identical to each other, and further, the shell diameter D1-D3 of each of the insulators 8A-8C is made suitable to the mechanical load. Therefore, the lugs 13a of hood are made uniform, and the shell diameters D1-D3 are made smaller in the order of 8A, 8B and 8C according to the distance from the column- substance side, and then, the creepage distance l1-l3 are set to be shorter one after another. Thus, the length of a connected assembly can be made to the shortest, and the hood diameter can also be made to the smallest. Thereby, a lightning protection insulator unit can be miniaturized and lightened, and at the same time, the draining of rain water is performed at each insulator, and consequently, the lightning protection characteristics can be improved.

Title: Mandrel bar for hot manufacturing seamless tube and hot manufacturing method of seamless tube
Inventor: IIDA SUMIO
IPC: B21B25/00
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To obtain a mandrel bar having longer life without generating burning even when the bar is used for rolling high alloy steel containing chromium by forming a chromium plating film in the range of the specific thickness on the mandrel bar. SOLUTION: The chromium plating film of 60-200 μm thick is formed on the surface of a base metal of the mandrel bar. The major cause of generation of burning is peeling of the chromium plating by heat cracks and a lot of burnings are generated in parts where the base metal of the bar is exposed by the elimination of the chromium plating film by wear, so it is necessary to thicken the chromium plating film and, when the thickness is 60-200 μm, the life is rapidly improved. The surface roughness Ra in the direction of the axial length of the base metal is defined as >=0.1 to <4 μm. Tool steel for hot working is preferable as the base stock of the mandrel bar. Even when the bar is used 100 passes or more in rolling the high alloy steel containing >=2 wt.% Cr in rolling with a mandrel mill, burning is not generated.

Title: Semiconductor inspection device
Inventor: SAITO TOSHIYA
IPC: H01L21/66
Filed: 1990-06-26
Abstract: PURPOSE:To improve the precision of measurement data by automatically changing the ultrasonic wave pulse voltage applied to the probe in accordance with changes in the temperature of the submersion medium in order to keep the ultrasonic wave attenuation constant independent of the temperature of the submersion medium. CONSTITUTION:A container 1 is filled with water and a measurement sample 3 is placed on the bottom of the container. Next, in order to increase resolution, a few tens of MHz ultrasonic wave is generated by an ultrasonic wave pulse generator 6. This ultrasonic wave pulse is applied to a probe 4 and the electromechanically-converted ultrasonic waves are sent toward the sample 3. When the water temperature increases, the viscosity changes and the rate of attenuation of the ultrasonic waves is altered. This in turn affects the strength of the ultrasonic wave echo signal. However, by monitoring the water temperature, when a water sensor 5 detects changes in the water temperature, a water temperature monitor 8 controls the ultrasonic wave pulse generator 6 accordingly and the output of ultrasonic waves is automatically adjusted, eliminating the effect of water temperature. This improves the precision of measurement data.

Title: Slippage detection for vehicle
Inventor: SATOMI YUTAKA
IPC: G01P3/56
Filed: 1986-07-17
Abstract: PURPOSE:To detect a tire slippage without determining any actual vehicle speed, by judging that a slippage has occurred when a ratio or a difference between rotational speeds of right and left drive shafts of a vehicle as calculated exceeds a slippage criterion. CONSTITUTION:Rotation sensors 1 and 2 detect rotational speeds NL and NR of right and left drive shafts 3 and 4 respectively to be outputted to a controller 5. An angle sensor 6 detects an angle S of steering of a steering wheel to be outputted to the controller 5. The controller 5 calculates a rotational speed ratio phi=NL/NR. Subsequently, thresholds T1-T4 are calculated by a specified formula to judge on the occurrence of a slippage based on the angle S inputted. Then, the rotational speed ratio phi is checked to be within a range of the thresholds T1 and T2 and when it is within the range, no slippage is determined to occur while a slippage is determined to occur, when it exceeds the range and an output of an engine is restricted. Moreover, the rotational speed ratio phiis checked to be within the range of the thresholds T3 and T4 and when it is within the range, no slippage is determined to occur and a normal injection value is outputted.
