Title: Self-aligning t gate hemt
Inventor: UMESHIYU KEE MISHIYURA
IPC: H01L21/335
Filed: 1990-11-30
Abstract: PURPOSE: To obtain a self-aligned T-gate high electron mobility transistor(HEMT), having a low parasitic resistance without performing high temperature processings by forming a mask layer having an opening aligned with a gate, so as to cover the surface of the gate and its surrounding area so that the opening can regulate first and second lateral intervals between both ends of the top section of the gate and edge sections of the opening. CONSTITUTION: The width of a mask 42 is decided, so that a first lateral interval 52 can be formed between the upper left end of the cross section of a T-shaped gate 34 and the edge section of an opening 44 adjacent to the upper left end, and a second lateral interval 54 can be formed between the upper right end of the cross section of the gate 34 and the part of the opening 44 adjacent to the upper right end. Metallic electrodes 48 and 50 are respectively stuck to a surface 14a in areas below the internals 52 and 54. The upper section 34b of the gate 34 functions as a mask in a dielectric side wall forming process and inhibits the adhesion of a metal to the surface 14a in an area vertically below the upper section 34b. Since the width of the gate 34 decides the channel width of a HEMT, etc., the channel width can be made narrower.  Therefore, a passivated T-gate HEMT, having a reduced gate resistance, can be obtained.

IPC: G11B7/085
Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To move an optical head to a target track while suppressing vibration at high speed with a simple and inexpensive system by directly driving the optical head by rotation of a motor rod and moving it. SOLUTION: A gear 12 is decelerated by the rotation of a motor 10 through a motor gear 11 and rotated. Then, a rod 13 of which one end part is formed integrally with the gear 12 is also rotated centering a rotation center shaft 16. The other end part of the rod 13 is inserted into an optical head 14 so as to be able to slide, and the optical head 14 is moved straightly along a guide 15 by the rotation of the rod 13. As the radius of rotation of an inserting part of the rod 13 is larger than the radius of rotation of the gear 12, a moving distance of the inserting part of the rod 13 is longer than a moving distance of a point on an outer periphery of the gear 12 in the same time. Therefore, high speed movement of the optical head 14 can be performed by a small rotation angle of the motor 10.

Title: Puffer type gas-blast circuit breaker
Inventor: KOIDE HIDENOBU
IPC: H02B13/02
Filed: 1992-12-18
Abstract: PURPOSE:To reduce the force required for controlling a drive rod so as to miniaturize a driving unit by providing at least one of slide rings with a notched portion, and interposing a compression spring between the slide ring and the circumferential groove of a fixed piston. CONSTITUTION:A slide ring 20 has a triangular notched portion 20A on the sliding-surface 5B side portion of the outer peripheral inside wall of a main puffer chamber 6 and a compression spring 21 is interposed between the notched portion and the bottom surface of a circumferential groove 8A. Thereby gas pressure within the main puffer chamber 6 is not built up in excess but held at a certain value. Since the slide ring 20 has a slit 22, it can be compressed toward its bore until a clearance formed by the slit 22 is eliminated. The force of the compression spring 21 is set so that the slide ring 20 is pressed against the sliding surface 5B until the gas pressure within the puffer chamber 6 reaches the minimum value required for breaking. Since a fixed piston 8 does not compress gas in the chamber 6 in excess, there is no need to increase a controlling force for a drive rod.
