Title: Wafer notch position detector
Inventor: IMANISHI AKIFUMI
IPC: H01L21/68
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To provide a wafer notch position detector which is capable of accurately detecting the position of a notch at all times, without causing any damage to the surface of a wafer and being affected by disturbance light or the like. SOLUTION: A wafer W is held by the edge with a holding means 1, whereby the holding means 1 is restrained from coming into contact with the surface of the wafer W, so that the surface of the wafer W can be protected against damage. The image of a part or all of the surface of the wafer W is picked up by an image sensing means 4 which is installed confronting the wafer W, and the position of a notch is detected by a notch position detecting means 5 based on the above image. Furthermore, it is preferable that an optical means generates a brightness difference between the wafer and its background on a picked-up picture image.  For instance, if the surface of a wafer is a mirror surface, a lighting means is installed at a position so as not to irradiate the image sensing means 4 direct with a reflected light from the surface of the wafer W, and a light scattering member 2 is provided to the background of the wafer W, the edge profile of the wafer W as a boundary between the wafer and the background is clearly reproduced, so that the position of a notch can be accurately detected, and a wafer notch position detector can be lessened in size because a rotating mechanism can be dispensed with.

Title: Connector for circuit board
Inventor: DAIKUHARA OSAMU
IPC: H01R13/52
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To remove granular material between a contact of each contactor of a low insertion force connector for a circuit board and each electrode pad of the board at the time of connection of the board so as to prevent a poor electrical connection between the connector and the board. SOLUTION: A main body 12 of a connector 10 has a reception part 18 which detachably receives a connection board. An inner wall 20 of the reception part 18 is formed with a guide face 22 and an oscillation fulcrum 26. The guide face 22 guides the connection board, while the oscillation fulcrum 26 supports the connection board at an edge part of a board insertion opening 16 side of the guide face 22 when the connection board is oscillated. Each contactor 14 has a contact 44 near its free end, which slidingly contacts with each electrode pad on a surface of the connection board. When the connection board is inserted, the oscillation fulcrum 26 of the reception part 18 of the main body 12 and the contact 44 of each the contactor 14 slidingly contact respectively with a rear surface of the board and with each the electrode pad.  When the connection board is completely inserted, a connection position between the oscillation fulcrum 26 and the rear surface of the board is relatively positioned far from a connection position between each the contact 44 and each the electrode pad in a view from a front end edge of the board.

Title: Rolling stock
Inventor: IWAI KENJI
IPC: C08L101/00
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To reduce noise inside a car in low cost and effectively without increasing weight of a vehicle by bonding damping resin on a truck frame and a part or whole of a hollow inner surface of a bolster. SOLUTION: When damping resin is bonding, the resin is bonded to a part, or whole surface of a hollow inner surface of a hollow structure throughout whole length in longitudinal direction. The damping resin 3 is bonded so as to cover whole rib part 1a which is an upper transmitting path of a bolster 1 formed by aluminum alloy extruded material and a truck frame. As a part bonded the damping resin having lower rigidity has larger absorbing action of oscillation energy, the resin is bonded to the rib part, 1 whose plate thickness is formed thicker than that of a face plate part. Whereby, noise inside a car can be reduced in low cost and effectively without increasing weight of a vehicle.

Abstract: PURPOSE:To detect the absolute position in many number of arbitrary rotations, by coupling the gears of two detecting parts each comprising a ring shaped resistor and a semi-circular terminal plate, and detecting the absolute position based on the detected outputs of the detecting parts. CONSTITUTION:First and second detecting parts (a) and (b) are composed of the following parts: ring shaped resistors 5 and 6; semi-circular terminal plates 7 and 8; first sliders 11 and 13 and second sliders 12 and 14, which are slidden on said resistors and terminal plates; and gears 9 and 10. The gears 9 and 10 are intermeshed each other. A shaft 1 of the first detecting part (a) is fixed to a rotary member for detecting a rotary position to be detected. Terminal voltages V1-V4 at said sliders 11-14, which are generated when the rotary member is rotated many times, are inputted into an operating electronic circuit. The operating electronic circuit outputs a voltage, which is linearly changed during the rotations of 0-(n) times, i.e., a voltage, which expresses the absolute position in many numbers of rotations, based on the terminal voltages. The number of many rotations, which can be detected, can be set by changing the gear ratio of the gears 9 and 10.

Title: Manufacture of high conductor using metal-metal oxide composite system
Inventor: SUMIDA NOBUO
IPC: H01B12/00
Filed: 1987-08-01
Abstract: PURPOSE:To improve the critical current property by composing a metal and a metal oxide coexistently, and controlling the interface structure and electron condition of the both components. CONSTITUTION:As a high dielectric rate substance, a metal and a metal oxide of the same type are selected to realize a metal-metal oxide coexistent system. By using a copper wire of the diameter 30mum, for example, it is baked up in the air at about 400 to 800 deg.C for about 15min to form an oxide over the surface. That is, CuO is produced at the outer surface of the copper wire, and CuxO is formed between the inner side of the CuO and the metal copper. The ratio of the metal with no relation to the mutual reaction with the metal oxide is made as little as possible. As a material to present a superconductive performance at a high temperature, a copper family metal such as silver and gold which is liable to make the oxidization and reduction easily other than copper, a platinum family metal such as osmium, iridium, platinum, ruthenium, rhodium, and palladium, or mercury is preferable. An alloy including such metals is also effective. In such a way, a superconductive material using a metal of a high electron density and a good ductility and malleability can be developed.
