Inventor: ROBAATO PII SHIYAATAMU
IPC: C08G59/30
Filed: 1989-10-12
Abstract: Epoxy resins containing aliphatic, non-hydrolyzable chlorine atoms are prepared by hydrochlorinating an epoxy resin thereby forming a chlorohydrin intermediate product; reacting this intermediate product with epichlorohydrin in the presence of a Lewis acid; and dehydrochlorinating the resultant product. The epoxy resins containing aliphatic, non-hydrolyzable chlorine atoms are useful for some coating formulations.

Title: Selective heating method of multilayer metal film
Inventor: IWASAKI TAKASHI
IPC: H01L21/28
Filed: 1984-12-14
Abstract: PURPOSE:To make it possible to heat the specified layer of multilayer metal films, which are formed on a semiconductor substrate and the like, selectively, by projecting light or an electromagnetic wave having a wavelength, which is selectively absorbed by the special layer of the multilayer metal films, on the multilayer metal films. CONSTITUTION:Light or an electromagnetic wave having a wavelength, which is selectively absorbed by the specified layer of multilayer metal films, is projected on the multilayer metal films. Thus the specified layer is selectively heated. For example, when only Ge in the multilayer metal films comprising gold and germanium is to be fused, light corresponding to 958-1,064 deg.C or light having a wavelength of 5,500Angstrom  corresponding to 958 deg.C is applied. The Au atoms reflect the light. Therefore, the light selectively reaches Ge. Therefore, the specified metal layer is selectively heated and the semiconductor substrate is not heated. The volatile component is not evaporated from the substrate. The isolated metal of an electrode, which is provided on a semiconductor wafer, is selectively heated. Therefore, the effect of the isolated metal is ensured.

Title: Heat-resistant corrosion-preventive coating film
Inventor: TOKUNAGA KIKUO
IPC: C09D5/08
Filed: 1987-10-20
Abstract: PURPOSE:To form the title coating film which has good adhesiveness, uniformly, and denseness, provides improved corrosion resistance, and is free from trouble due to silica scaling, by attaching a mixture containing an alkaline earth metal carbonate to the surface of a heat exchanger tube in a high-temperature section with an aluminate binder. CONSTITUTION:This heat-resistant corrosion-preventive coating film is formed by attaching a mixture containing at least one alkaline earth metal carbonate to the surface of a heat exchanger tube in a high-temperature section of, e.g., an oil-fired boiler, a boiler for power generation or a boiler for sodium carbonate recovery with an aluminate binder (e.g., an aqueous solution of sodium aluminate). Since an alkaline earth metal carbonate is dispersible thoroughly in an aluminate binder, a coating film with good adhesiveness, uniformity, and denseness can be obtained, the corrosion resistance can be remarkably improved and there is nothing to worry about the trouble due to silica scaling in a process of concentrating a waste liquor in a boiler for sodium carbonate recovery.
