Title: Pendulum type angle detector
Inventor: SHIMIZU MIYUKI
IPC: G01C9/12
Filed: 1983-01-21
Abstract: PURPOSE:To improve durability and reliability by coupling an arm and a weight together through a hinge, and rotating the weight and reducing a thrust-directional component of force when the shaft of a detector body slants from a horizontal state. CONSTITUTION:The angle detector 11 holds the arm 16 invariably perpendicular by the gravitational force of the weight 17. When the boom of a crane equipped with the angle detector 11 is raised, the housing 14 of the angle detector 11 rotates counterclockwise accordingly. Therefore, the weight 17 moves relatively to the housing 14 to rotate the shaft 15 through the arm 16. The angle detector 11 detects the rotation of the shaft 15 through a potentiometer 12 and detects the angular displacement of the boom.

Title: Manufacture of superconducting oxide coil
Inventor: TOMINAGA HARUO
IPC: H01F6/06
Filed: 1988-01-18
Abstract: PURPOSE:To increase the critical current density, by forming a wire rod into a coil shape through application of a pressure to obtain a specified area- reduction factor. CONSTITUTION:Wire rod 4 is obtained by filling and sealing superconducting oxide powder in a pipe made of metal or an alloy, and then by extending or rolling the pipe. After that, the wire rod 4 is formed into a coil shape, drafting the wire rod 4 by an area reduction factor of more than {100(d/2D)+3} with a pair of rolls 2, 3 with grooves whose peripheral speeds are different from each other. In the equation, D is the coil diameter prescribed by the central axis of the wire rod 5 which has gone out of the rolls 2, 3, and (d) is the diameter of the part which the superconducting oxide occupies in the wire rod 5. This prevents the superconducting oxide of the coil periphery from cracking after the formation. Accordingly, the cutting of a path having superconductivity can be avoided, and the critical current density can be increased.

Title: Displaying method for defective chip
Inventor: UENO YOICHI
IPC: H01L21/66
Filed: 1990-01-17
Abstract: PURPOSE:To execute a classification of a defective chip by color without any contact with the surface of the chip during a wafer test process by a method wherein, in a wafer process, the surface of a semiconductor wafer is coated with a photosensitizer in advance and its color is changed in the test process. CONSTITUTION:A semiconductor wafer 1 placed on a movement stand 5 is moved regularly under a light-emitting machine 3. Since the light-emitting machine 3 emits special light 8 by a signal of a controller or a tester 4, the signal is sent from the controller 4 when a defective chip is situated under the light-emitting machine 3 and a photosensitizer 2 on the chip is irradiated with the light 8. The color of the photosensitizer 2 is changed and a discolored region 6 is produced. When the signal is not sent from the controller 4 and the stand 5 is moved, the color of the photosensitizer 2 is not changed and an unchanged region 7 is produced. As a result, this chip can be discriminated from the defective chip. Thereby, it is possible to classify a nondefective chip and the defective chip by color without any contact with the wafer 1; it is possible to prevent the wafer 1 from being damaged and a wafer stand from being damaged. Since the photosensitizer is coated during a wafer process, it is possible to omit the painting operation of a coating agent during a wafer test..
