Title: Method for cutting ceramics with laser beam
Inventor: KOBAYASHI TAKURO
IPC: B23K26/38
Filed: 1985-02-12
Abstract: PURPOSE:To prevent occurrence of cracks in products, by providing a coating layer of an inorganic substance on the upper surface of a work and simultaneously performing laser beam irradiation and gas blowing upon the work from the top side. CONSTITUTION:A coating layer 2 made of an inorganic substance which does not evaporate or destructively vaporize is formed on the upper surface of a work 1 of a ceramic material. The tip of a torch 3 is positioned onto the coating layer 2 and a laser beam 5 is condensed to the coating layer 2. When the laser beam 5 is irradiated, a gas of O2, etc., is supplied into the torch 3 from a gas supplying tube 6 and simultaneously blown upon the coating layer 2. High-temperature molten matters 8 produced by the laser beam 5 are made to flow by the blown gas and melt the work 1 and the mixed molten matters 9 are finally blown off by the gas. Since the thermal shock of the laser beam 5 is eased when this cutting method is applied, occurrence of cracks in the work 1 can be prevented.

Filed: 1989-02-06
Abstract: PURPOSE: To obtain a molded product, wherein two thermoplastic layers are present in a superposed state, by a two-component injection molding method by adding a polyarylene sulfide, pref., polyphenylene sulfide as at least one component. CONSTITUTION: When a polyarylene sulfide, pref., polyphenylene sulfide is used in a two-component injection molding method, an injection-molded product wherein the polyarylene sulfide becomes a core and the periphery thereof is surrounded by a second component can be formed. This molded product can be easily subjected to metal plating, printing or coating and high-order surface gloss is obtained. For example, the reflecting plate of a head lamp is produced from the two-component injection-molded product but, in this case, the polyarylene sulfide becomes a core and other thermoplastic substance, for example, polycarbonate becomes an outer shell. By this constitution, a head lamp having high heat resistance, not affected by a sudden temp. change and having high mechanical strength and excellent surface characteristics can be produced.
