Title: Optical disk
Inventor: TAJIMA TETSUO
IPC: G11B7/24047
Filed: 1986-06-11
Abstract: PURPOSE:To improve transparency, heat resistance and moisture resistance by using a polycarbonate resin consisting of a specific repeating unit and having the softening point within a set range as a base material. CONSTITUTION:The polycarbonate resin consisting of the repeating unit expressed by the formula and having the softening point within a 150-300 deg.C range is used as the base material. An optical disk consisting of the polycarbonate resin is susceptible to deformation such as warpage and twist by the effect of heat if the softening point is lower than 150 deg.C and molding is considerably difficult if the softening point is higher than 300 deg.C and such is undesirable in either case. The polycarbonate resin is transferred with pits for recording signals by an injection molding or press molding method using a metallic mold set with a stamper, by which the disk base material is molded.

Abstract: PROBLEM TO BE SOLVED: To prevent generation of chip deposition and chip dropping by rotating the tip end of arms, after welding is completed, as the rotation shafts, wherein the arms protruding towards a welding piece, and welding chips to be installed at the tip end of the arms are equipped. SOLUTION: The spot welding is carried out with a spot welding gun 21, to which the welding chips 31 are installed at both of the tip end, by contacting the chips 31 with joining parts W1, W2 of a piece W to be welded. Then, both arms 23, 23 tip ends are made to be rotated with the tip end cores as the rotating shafts. By doing so, one or both of welding chips 31 are twisted at the contacting points with the welding piece W within a range of 10-30 deg., and are separated from the welding piece W even when they are deposited with the welding piece W. Twisting of 10 deg. or less is not sufficient to release the deposition. The twisting operation of 30 deg. or more is not desirous, as a moving volume of the arms 23 becomes too large.

Title: Semiconductor substrate
Inventor: TAKAHASHI YASUHITO
IPC: H01S5/00
Filed: 1993-06-04
Abstract: PURPOSE:To provide a substrate that greatly improves the efficiency of hole injection by growing II-V compound having a small lattice constant on a p-type substrate, and deforming its valence band through distortion in preparing a blue luminous element having an oscillation wavelength of 500nm or so. CONSTITUTION:A p-ZnSSe 2 of a small lattice constant is grown on a p-GaAs substrate 1, and the boundary is greatly distorted to largely deform the valence band of the p-ZnSSe. As a result, degeneration is eliminated, and the light holes come above the heavy holes. Further, the band gap is narrowed, and the light holes come to contribute to conduction. This reduces the height and effective mass of barriers against holes, which increases transmittivity and greatly improves the efficiency of hole injection.

Title: Supersonic cleaning method
Inventor: TOKOROYAMA FUKUSABUROU
IPC: H01L21/306
Filed: 1984-07-02
Abstract: PURPOSE:To inhibit cleaning unevenness and stimulative noise by blocking the formation of quasi-fault voids by a method wherein the pulse width of pulses which modulate supersonic waves is adjusted according to the kind of cleaning liquids and the peak output of supersonic waves. CONSTITUTION:Cavitation is generated by radiating supersonic waves in the cleaning liquid. The supersonic waves are impressed by pulse modulation. The modulation period T is adjusted according to the kind of cleaning liquids, and pulse widths t1 and t2 are adjusted according to the peak output of supersonic waves. Since the radiation of supersonic waves is stopped for a short time at every fixed time on account of pulse modulation, voids do not grow so large. Therefore, the generation or formation of quasi-fault voids can be inhibited.
