Patent JP-S62124744-A (JP)
Title: Etching method
Inventor: SASAKI YOSHITAKA
IPC: H01L21/306
Filed: 1985-11-26
Abstract: PURPOSE:To prevent the generation of insufficient etching by dipping a wafer in an etchant approximately half and generating largely moving bubbles on the surface of an etchant liquid through bubbling from the bottom. CONSTITUTION:Bubbles are generated from pipes 13a and 13b and holes 14a and 14b through etching, a large number of large bubbles 15 are also formed on the level of an etchant 12, and bubbles are generated successively from the pipes, thus gradually shifting bubbles 15 on the level upward. Accordingly, large bubbles 15 transfer along the surfaces of wafers 10, thus removing small bubbles, which are formed as the result of a chemical reaction among aluminum on the wafers and the etchant 12 and adhere on the surfaces of the wafers.

Title: Stored mirror control device of vehicle
Inventor: KAWASHIMA NAOKI
IPC: B60R1/06
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To enable the traveling while a mirror is stored without damaging the automatic developing function by the vehicle speed and without requiring any troublesome operation. SOLUTION: In a stored mirror control device, when the initial signal is outputted from a mirror switch 3 after an ignition switch 2 is turned on, the automatic developing function to develop a mirror 5 by the vehicle speed (the non-development preventing function) is canceled. Traveling can be achieved while the mirror 5 is stored only by storing the mirror 5 after the ignition switch 2 is turned on.

Title: Production of magnetic recording medium
Inventor: HONDA KAZUYOSHI
IPC: G11B5/85
Filed: 1989-10-11
Abstract: PURPOSE:To obtain such a magnetic medium which causes little wearing of a head by heating the surface of the medium after forming a magnetic layer, applying a liquid lubricant on the medium and then polishing. CONSTITUTION:A magnetic layer essentially comprising Co-Cr or Co-Cr-Ni is formed on a long-sheet polymer substrate by vapor deposition. The obtained medium is heated in an oxygen atmosphere, coated with a liquid lubricant and then properly polished. By polishing the surface, sharp projections or the like which cause wearing of a head can be removed. Without applying the lubricant, surface profiles required for maintaining the traveling property of the medium are also diminished by polishing. However, by applying the liquid lubricant before polishing, only sharp projections can be removed.

Title: Method and equipment for manufacturing self-adhesive film or sheet
Inventor: KONISHI MASAAKI
IPC: C09J7/02
Filed: 1990-10-02
Abstract: PURPOSE:To make it possible to obtain a good self-adhesive undergoing little change in constitution with less usage of an inert gas by providing a light-screened section between a continuous coating section and an irradiation section, filling a whole chamber with an inert gas, and keeping the concentration of oxygen in the atmosphere below a specified ppm. CONSTITUTION:A base film 1 and a double-side release paper 11 are introduced through inlets 6 into a chamber A and put together through a back-up roll 22. In a coating section 2, a photosensitive composition 21 is applied to the base film 1 by adjusting the gap between the back-up roll 22 and a metering roll 23. The base film 1 coated with the composition 21 is laid on top of the sheet 11, which pass through a light- screened section 3 and go into an irradiation section 4. The composition is irradiated with light emitted from an irradiation device 41 and polymerized to give a self-adhesive. Since the chamber A is filled with an inert gas and the concentration of oxygen in the atmosphere is kept at 1000ppm or lower, the concentration of oxygen dissolved in the composition will be reduced to 0.1ppm or lower by irradiation with light so that the polymerization proceeds, thus giving a good adhesive. The base film 1 coated with this self-adhesive and the release paper 11 are withdrawn through an outlet 7 and rolled up on a product take-up machine 5.
