Title: Formation of antireflection film
Inventor: OGURA TOSHIAKI
IPC: G02B1/11
Filed: 1986-09-02
Abstract: PURPOSE:To obtain an antireflection film having excellent adhesiveness and durability by subjecting an optical glass element formed by press forming of an etched glass article to an ion bombardment treatment in air or inert gaseous atmosphere in a vacuum vessel, then forming the antireflection film thereon. CONSTITUTION:The stock of lead glass is ground to a biconvex spherical shape of a prescribed radius of curvature and, for example, 8mm central wall thickness in rim diameter. After such glass stock is immersed in, for example, 10% hydrofluoric acid at a prescribed temp., the stock is cleaned with distilled water and is dried by a drying machine. The glass article obtd. by repeating such immersion stage is press-formed for 2min under, for example, 10kg/cm<2> molding pressure at a specified temp. by using a pair of mirror-finished dies respectively having the specified radius of curvature. MgF2 is thereafter deposited on the optical glass element by a vacuum deposition method. More specifically, the inside of a vacuum vessel subjected to evacuation is heated and a prescribed voltage is impressed to a bombardment electrode to generate glow discharge, by which the ion bombardment treatment is executed and the MgF2 is formed to the prescribed optical film thickness by resistance heating.

Title: Automatic centering bearing
Inventor: KUMAZAWA SHIN
IPC: F16C33/74
Filed: 1983-11-02
Abstract: PURPOSE:To enable production of a sealing effect even if centering is widely deviated, by a method wherein a cylindrical member, swung integrally with a bearing member, is mounted to the bearing member, and a sealing member, which seals a gap between the cylindrical member and a rotary shaft, is attached to the cylindrical member. CONSTITUTION:Cylindrical members 11 and 12 are threadedly attached to both sides of a bearing member 3 by means of O-rings 9 and 10 in a manner to hold a liquid-tight state. Sealing members 13 and 14, which seal a gap between each of the cylindrical members 11 and 12 and a rotary shaft 7, are respectively located to the external parts of the cylindrical members 11 and 12, and the interior of each of the cylindrical members 11 and 12 is formed as an oil chamber 15. When bending occurs to the rotary shaft 7, the cylindrical members 11 and 12, to which the sealing members 13 and 14 are attached, are swung integrally with the bearing member 3. This, even if a swing amount is increased, prevents the occurrence of a change in a relative position between each of the sealing members 13 and 14 and the rotary shaft 7 and enables production of normally stable sealing effect.

IPC: C01B33/02
Filed: 1994-08-31
Abstract: PURPOSE: To make a single crystal silicon obtained from a polycrystal silicon higher purity by successively cleaning the surface of a polycrystal silicon contaminated by iron atom with an oxidizing chemical, water and a chemical capable of decomposing oxidized film. CONSTITUTION: A polycrystal silicon mechanically worked by grinding, polishing, etc., in order to pull up single crystal silicon and having the surface contaminated by an iron 1 kept in a metal state or an iron 2 kept in an atom state and diffused in the vicinity of the surface is cleaned with an oxidizing chemical such as aqua regia. Thereby, a reaction forming oxidized film on polycrystal silicon surface by oxidation and a reaction dissolving and removing the iron 1 kept in metal state are simultaneously advanced and the iron 1 kept in metal state and the iron 2 kept in atom state are gathered into the interface between the polycrystal silicon and the oxidized film. Then the surface of the polycrystal silicon is washed with water to remove the oxidizing chemical and cleaned with a chemical capable of decomposing the oxidized film, e.g. hydrofluoric acid.  Thereby, the iron atom taken in the interior of silicon oxidized film is dissolved and removed by H2 SiF6 produced, accompanied by removal of the silicon oxidized film, because the acid is extremely strong acid.
