Title: Method for finishing edge of plate glass
Inventor: TANAKA KEISUKE
IPC: B24B9/10
Filed: 1994-10-26
Abstract: PURPOSE: To improve the edge strength of a glass plate by polishing the end surface of a plate glass into a curved surface shape which projects outward, and finishing the boundary part between the curved surface part of the end surface and the flat surface parts on the front and back sides of the glass smoother than the curved surface part. CONSTITUTION: A curved surface part 3a projecting outward is polished on the end surface of a plate glass 3 by using the outer peripheral surface of a cylindrical wheel 10 to be rotated around its shaft core. A polishing part finer than the abrasive of No.200 is formed on the outer peripheral surface of the cylindrical wheel 10, and irregularities in the front surface of the curved surface part 3a is finished into about 0.03. Next, the boundary part 3c between the curved surface part 3a and the flat surface parts 3b is buff-polished by using the outer peripheral surface of the polishing belt 11 to be rotated. Polishing by the polishing belt 11 is performed by sufficiently pouring aqueous solution of cerium oxide on the part to be polished, and the surface roughness is finished to a few μm.

Title: Production of resinous coating film
Inventor: ASANUMA TADASHI
IPC: C08G18/02
Filed: 1993-10-21
Abstract: PURPOSE:To obtain a satisfactory heat-resistant resinous coating film by heating an aromatic diisocyanate in an organic solvent in the presence of a phosphorus compound catalyst, applying the resulting solution of a polycarbodiimide to a metal plate, drying the coating, and then irradiating the coating with ultraviolet. CONSTITUTION:An aromatic diisocyanate, e.g. benzene diisocyanate, is thermally polymerized in an organic solvent (e.g. benzene, toluene, or dichloroethane) in the presence of a phosphorous compound catalyst to produce a solution of a polycarbodiimide. Examples of the catalyst include 1-phenyl-2-phosphorene-1- oxide. The polymerization is preferably conducted in the presence of a monoisocyanate and an alcohol so as to improve shelf stability. Dissolving an epoxy or cyanate compound in the solution before use is effective in improving film properties. The resulting solution is applied to a metal plate, dried, and then irradiated with ultraviolet, for example, with a medium-pressure mercury lamp at 250 deg.C for 2hr. The thus-obtained resinous coating film is satisfactory in heat resistance and adherence and has higher hardness than the film cured by heating only.
