Title: Manufacture of optical disk base
Inventor: FUKAMACHI YUICHI
IPC: G11B7/26
Filed: 1986-11-13
Abstract: PURPOSE:To provide a manufacturing method of an optical disk base having a high reliability, in a few manhour, by applying specific ultraviolet rays to photo-setting resin (2P) where a guide groove is formed. CONSTITUTION:A short wavelength UV of ultraviolet rays having a peak in 250nm or shorter is applied to 2P where a guide groove is formed. As the ultraviolet rays possess sufficient energy to cut off a chemical bond, a monomer ingredient remaining in the 2P can be removed from the 2P through cure due to crosslinking reaction. Then a degassing process can be omitted by removing water content in the resin thermally in a short period of time. As a 2P layer is several mum in thickness, the 2P itself is heated with the short wavelength UV, and adhesion strength between the 2P and the base is improved. Therefore, manufacturing of an optical disk base superior in reliability such as heat resistance and moisture resistance becomes possible.

Title: Method of isolating semiconductor device through trenches
Inventor: SHIN YU-GYUN
IPC: H01L21/76
Filed: 1998-09-24
Abstract: PROBLEM TO BE SOLVED: To improve the junction leakage current characteristic by recovering a damaged layer caused during forming of the trench isolation and forming regions, from which O impurity is removed. SOLUTION: This method comprises the steps of etching a semiconductor substrate to form trenches 16, forming a thin thermal oxide film 28 on the walls of the trenches 16, heat treating at about 1,000-1,200 deg.C for about 1-8 hrs. to recover the substrate damaged during forming of the trenches, removing O impurity 20 from the substrate, filling up the trenches 16 with an insulator to form element isolating regions. The heat treating step for recovering the damaged layer caused during the formation of the trenches 16, prior to the trench lifting permits the compacting step heat treating temp. of a CVD oxide film for filling up the trenches to be lowered, and hence the distortion possibility of the semiconductor substrate can be be lessened to improve the element junction leakage current characteristic.

IPC: H01M2/12
Filed: 1986-11-13
Abstract: PURPOSE:To make it possible to exhaust gas within a container without the coming off of a metallic sealing plate from a metallic container when the inner pressure of a battery is increased by forming a vacant space between the inner surface of the opening bent end of the metallic container and the cut-out part of an insulating sealing member. CONSTITUTION:A circular cut-out part 31 is installed in a part of a cylindrical side wall 30 of an insulating sealing member 28. A metallic sealing plate 32 is placed on the sealing member 28, and the opening 33 of a metallic container 21 is shrunk in a radius direction. The upper end of the wall 30 is bent on the upper surface of the periphery of the sealing plate 32. The sealing strength of the sealing plate 32 is weak in the cut-out part 31, and a vacant space 34 is formed between the inner surface of the opening 33 and the cut-out part 31. When gas pressure inside a battery is increased, the sealing plate 32 is easily lifted in the cut-out part 31, and the gas is exhausted outside through the vacant space 34. Therefore, the breakage of a battery caused by an increase in gas pressure can be prevented.

Title: Method and mold for manufacturing molding
Inventor: TANAKA TAKAYOSHI
IPC: B29C45/57
Filed: 1995-10-19
Abstract: PROBLEM TO BE SOLVED: To obtain a molding that shrink is prevented without providing a gas channel of a particular thick part in the molding. SOLUTION: To manufacture a molding having a rib, a nitrogen gas filling port 27 is provided near a gate 24 for charging a molten resin. When 40 to 90% of the molten resin 3 is charged in a mold 2, the injection of the gas is started from the port 27. After the gas starts to be invaded into the resin 3, the injection of the gas is stopped, and the pressure of the gas in the mold 2 is reduced to the necessary minimum limit to secure the quality of a molding. The injected gas is spread in the entire rib molding part 30B of the mold 2 along a rib molding part 30B to urge the resin 3 toward the molding surface. Accordingly, even if a hollow part called 'a gas channel' is not particularly provided, shrink is prevented and the external appearance failure due to the channel is eliminated as well.
