Title: Method of processing semiconductor substrate, semiconductor substrate, method of evaluating semiconductor crystal, and method of manufacturing semiconductor device
Inventor: YAMADA NAOKI
IPC: H01L21/66
Filed: 1994-12-07
Abstract: PURPOSE: To avoid oxygen deposition near surface by a method wherein a surface processed and exposed semiconductor substrate at a specific temperature is put in a nitrogen gas atmospheric furnace and then the furnace is heated up to outside diffusion heat treatment temperature to detect the oxygen diffused outside from CZ-Si crystalline surface. CONSTITUTION: An insulating film 2 such as SiO2 etc., formed on a semiconductor substrate as Si etc., to expose the semiconductor substrate. Next, surface exposed semiconductor substrate 1 is put in a furnace at the temperature not exceeding 300 deg.C (e.g. 100 deg.C) and in N2 gas atmosphere. Next, the frame is heated up to outside diffusion processing temperature e.g. 1150 deg.C for heat treatment to outside diffusion process the impurities such as the oxygen, etc., in the semiconductor substrate surface part. Through these procedures, the oxygen density in the depth of 5μm from the semiconductor substrate 1 surface dose not exceed 1E5 (atoms/cm<3> ) while that in the depth exceeding 10μm exceeds 5E7 (atoms/ cm<3> ).

Title: Rolling bearing used in magnetic field environment
Inventor: YAMAMOTO KENJI
IPC: C10M103/00
Filed: 1993-12-03
Abstract: PURPOSE:To make rotation smooth in the case of being used under the magnetic field environment by forming inner and outer bearing rings of steel, and forming rolling elements between both bearing rings of ceramics. CONSTITUTION:When a first joint member 3 is rotated by drive mechanism, attracting force acts between the permanent magnets 8A, 8B of the magnet ring 7 of the first joint member 3 and the permanent magnets 19A, 19B of the magnet ring 18 of a second joint member 15, and the second joint member 15 is rotated by the same quantity in the same direction as the first joint member 3. Since both inner and outer rings 11, 12 and 22, 23 of ball bearings 9, 21 are formed of steel, and the balls 13, 24 of the ball bearings 9, 21 are formed of ceramics, the increase and fluctuation of torque under the influence of the magnetic field can be suppressed. Also, since the magnetic flux is concentrated on the groove 14 of the outer ring 12 and the groove 25 of the inner ring 22, abrasive powder generated from both inner and outer rings 11, 12 and 22, 23 made of steel is collected into the grooves 14, 25 by the attracting force. The abrasive powder is thereby prevented from biting into a raceway track so as to make rotation smooth.

After the vehicle passes at least the point tp2, a constant-speed transit curve Va of the vehicle C is set beforehand based on the characteristics and elongating amount of the towing rope and the running resistance value of the entire system at the command speed of collision. Then, acceleration is performed by speed control to the vicinity of the command speed in accordance with the instructed value of the accelerations obtained from time to time by the operation of the function of the running resistance of the moving body. The resistance value is computed by using at least two points during the acceleration of the moving body as references.

IPC: B62J13/02
Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To provide a motor bicycle belt cover wherein its deformation can be prevented due to improved rigidity without any increase in weight or cost. SOLUTION: A plurality of ribs 21e (21e1 to 21e8) are mounted on the internal corner portion of a belt cover 21 covering a belt 19 of a motor bicycle at regular intervals along the longitudinal direction of the vehicle body. Height of each rib 21e is made variable so that a clearance δ between the ribs 21e and the belt 19 at rest becomes larger toward the forward portion of the vehicle body. Thereby a plurality of ribs 21e improve rigidity of the belt cover 21, enabling prevention of deformation of the belt cover without any increase in weight or cost. Furthermore, the height of each rib 21e can be set to the maximum as long as interference with the belt 19 when driven can be avoided. And reinforcement effect of the belt cover 21 by means of a plurality of ribs 21e can be obtained most efficiently.  These are because the height of each rib 21e is made variable such that the clearance δ between the rib 21e and the belt 19 at rest becomes larger toward the forward portion of the vehicle body.
