Title: Spectacle frame and manufacture thereof
Inventor: TOKUMARU KAORU
IPC: C25D5/56
Filed: 1987-08-21
Abstract: PURPOSE:To obtain a spectacle frame, which is excellent in dimensional stability, heat resistance, weatherability, chemical resistance and toughness and easily pigmented and ornamentally excellent, by a method wherein the spectacle frame concerned is produced by injection-molding synthetic resin mainly made of polyarylate-based resin. CONSTITUTION:A spectacle frame is injection-molded out of synthetic resin mainly made of polyarylate-based resin. In addition, a heat-treated decorative coating layer is formed on a part of or the whole of the frame surface by heat-treating the decorative coating layer together with the spectacle frame at about 150 deg.C. Since the polyarylate resin is thermoplastic amorphous resin and has mold shrinkage factor, which is smaller than that of crystalline resin, and low coefficient of water absorption, the molded frame has high dimensional stability. Further, since the resin has very high heat deformation temperature and its mechanical characteristics are kept even at elevated temperature, the molded frame is excelled in heat resistance. Furthermore, since the resin has excellent ultraviolet light resistance and almost no change in its mechanical characteristics occur even through the exposure to sunlight over a long period of time, the molded frame is excellent in weatherability. In addition, the molded frame has excelled chemical resistance and toughness and high impact strength and characteristics that its toughness is kept in a wide range of ambient temperatures and the like.

Title: Treatment for recovery of copper plating liquid
Inventor: TAKURA TOMOJI
IPC: H05K3/18
Filed: 1990-08-07
Abstract: PURPOSE:To easily remove impurities such as sodium sulfate at low cost by treating a copper plating liquid to remove org. matters by adsorption of active carbon and treating the plating liquid to pass through a reverse osmosis film, having specified permeability for sodium sulfate and sodium formate and specified permeability for copper and chelate compds. CONSTITUTION:Org. matters molten from a substrate into the copper plating liquid or org. matters as byproduct can be removed by passing a copper plating liquid through an active carbon tower since these matters adsorb on the active carbon. After passing the liquid through the active carbon tower, the liquid is then passed through a reverse osmosis film. This reverse osmosis film has >=80% permeability for sodium sulfate and sodium formate and <=20% permeability for copper and chelate compds. By passing the copper plating liquid through the reverse osmosis film, most of sodium sulfate and sodium formate permeate while copper and chelate compds. remain in the liquid which do not permeate the film. Then, this remaining liquid is sent to a liquid before the copper plating treatment, and thus, the plating liquid can be reused.
