Title: Reversing mechanism for semiconductor chip
Inventor: KOMURA MASARU
IPC: H01L21/52
Filed: 1986-10-13
Abstract: PURPOSE:To eliminate a repetitive operation and to improve the productivity by a method wherein a holding head of a semiconductor chip is supported at a support base so as to be turned by 180 deg. and the head is linked with a half-turn driving means. CONSTITUTION:A chip which is held in a definite direction is sucked and held at the lower end of a pipe 15 of a holding head 11.

Abstract: PURPOSE:To always keep the temperature in a constant temperature oven constant even when an ambient temperature exceeds a temperature corresponding to a zero coefficient of a crystal resonator by employing a Peltier element used in common as two means as a heater and a cooling body so as to attain free temperature control in the constant temperature oven. CONSTITUTION:A Peltier element 15 is fixed onto an outer circumferential face of a constant temperature oven 10 having a crystal resonator in its inside, and the direction of a current flowing to the Peltier element 15 is controlled to heat or cool the Peltier element thereby keeping the temperature in the constant temperature oven constant.

Inventor: BOO ATSUPEERU
IPC: F16D1/08
Filed: 1990-09-12
Abstract: PURPOSE: To provide a compact coupling dispensing with reconstruction by interposing a coupling member radially expanded by supply of a pressure fluid, between first and second parts so as to apply larger coupling force to the first part, and allowing rotation between the coupling member and the second part. CONSTITUTION: A coupling 10 couples an axle-type first part 11 to a hub-type second part 12. A coupling member 15 has a pressure medium chamber 16 partitioned radially inward and outward by sleeve parts 17, 18. When a pressure medium such as oil is fed, the sleeve parts 17, 18 expand to connect the first and second parts 11, 12. The sleeve part 17 is thick-walled, and its coupling force to the hub (second part) 12 is smaller than its coupling force to the axle (first part) 11. When a pressure relief device comprising a corrugated pipe 25, a ring 26 and an arm 27 is triggered, the coupling 10 is freely rotated on the axle 11. After a slip caused by high torque in a short period, the hub is rigidly fixed to the coupling member 15. The compact coupling dispensing with reconstruction is thus obtained.
