Title: Manufacture of grain-oriented silicon steel sheet minimal in iron loss
Inventor: NISHIIKE UJIHIRO
IPC: C21D8/12
Filed: 1986-06-12
Abstract: PURPOSE:To reduce iron losses due to mirror-finishing treatment of silicon steel sheet surface, by removing the surface oxides of a mirror-finished grain- oriented silicon steel sheet, by further polishing the above into a smooth surface having a specific roughness, and then by applying stress relief annealing. CONSTITUTION:After the surface oxides formed on the surface of the finish- annealed grain-oriented silicon steel sheet are removed, the above surface is finished into a smooth surface of <=0.3mum surface roughness Ra by means of mechanical polishing by use of polishing roll, buff, etc. This steel sheet is laminated or wound up in a coil and, in the above state of close adhesion, the sheet is subjected to stress relief annealing in a nonoxidizing atmosphere. In this way, remarkable reduction in iron losses can be attained. Moreover, if an acidic protective coating, such as Al2O3, etc., having tension-providing function as well as superior heat resistance is formed, after the formation of smooth surface, prior to stress relief annealing in the above method, magnetic properties can be improved to a greater extent.

Title: Laser reflecting mirror
Inventor: HIGUCHI FUMIAKI
IPC: G02B5/08
Filed: 1988-05-31
Abstract: PURPOSE:To eliminate the stains of a reflecting mirror without damaging the surface at a low cost by forming a thin film consisting of molybdenum on a reflecting mirror base plate consisting of copper or alloy essentially consisting of copper. CONSTITUTION:The thin film 7 consisting of the molybdenum is formed on the reflecting mirror base plate 1 consisting of the copper or the alloy essentially consisting of the copper. The surface hardness is thereby increased in the same manner as with a laser reflecting mirror consisting of the molybdenum as a base plate. Even if, therefore, sputters and the scorches of mists, etc., are deposited on the reflecting mirror during the use thereof, such stains can be wiped away by a solvent such as trichloroethylene or alcohol to clean the surface. Removal of the stains such as sputters with a nylon brush, etc., is possible as well. The inexpensive cleaning of the laser reflecting mirror is attained in this way and the surface flawing is obviated even if the surface stains are removed.
