Filed: 1979-10-02
Abstract: PURPOSE:To facilitate the deburring of the molded resin in the lead frame for the integrated circuit, by selectively performing the treatment of the surface of the material in the region on which a gold or silver film is formed, and improving the close contacting property of the film. CONSTITUTION:The surface of the lead frame of an iron-nickel alloy is selectively masked with a masking jig such as silicon rubber and the like. A partial aventurine surface 8' having the diameter of concave and convex parts of about 20mum and the roughness of 0.1-0.2mum is obtained by the etching for 30-90sec by using acid comprising sulfuric acid, fluoride, and hydrogen peroxide. Then, a silver film 9, which is about 20mum thick and has strong contacting property, is formed by silver- plating the partial aventurine surface 8'. Thereafter, a semiconductor element is placed on the film part, bonding is performed, and the molding is made by resin. The silver film 9 has excellent contacting property because of the partial aventurine surface 8'. Since aventurine treatment is not applied on an outer lead part 7, the deburring work is easy.

Abstract: PURPOSE: To prevent the fluctuation in amt. owing to gas locking and changing over by starting the injection from other pressurizing tank prior to the end of injection by a pressurizing tank as a device of injecting sodium hyochlorite for disinfection into water.  
     CONSTITUTION: A sodium hypochlorite soln. is supplied from a storage tank to a pair of pressurizing tanks A, B and is pressurized by a compressor 12. The injection is accomplished by opening the injection valve 3a of the tank A and through a flow rate control system. When the liquid level lowers on the injection and a liquid level gage 6a detects a low level LL, the pressurizing valve 2b and injection valve 3b of the tank B are opened to start injection in parallel. Further when the liquid level of the tank A lowers down to an injection level LL, a pressurizing valve 2a and an injection valve 3a are closed. Since none of pumps are used in this way, there is no possibility of gas locking and the fluctuation in flow rate owing to changing over is prevented.

An optical head secures an approximately 8 GB recording capacity by irradiating an optical disk 12 with the laser beams having the wavelength of less than 680 nm through the optical system with the numerical aperture of more than 0.7. At that time, a working distance WD is set to less than 560 μm and the mass-production of the heads are made possible. Thus, the video recording time and the operability comparable to a video tape recorder are obtained and the editing, which effectively uses the random access function of the optical disk device, is made possible.
