Title: Method for preventing corrosion of corrodible metal
Inventor: YAMAMOTO YUJI
IPC: C23C14/34
Filed: 1991-12-26
Abstract: PURPOSE:To improve the corrosion resistance and durability of a corrodible metal such as Ag by forming a satisfactory protective film on the metal. CONSTITUTION:A coating film of a dielectric such as TiO2 is formed on the surface of a corrodible metal such as Ag with an indium tin oxide (ITO) film and the metal is heated in the air. The resulting TiO2/ITO film acts as a nonsacrificial anode and attains the cathodic protection of Ag. Even when part of the corrosion preventive film peels by some cause and the base metal is exposed, unlike a plated metal, this coated metal prevents the progress of corrosion from the exposed part to the entire base metal because the base metal acts as a cathode to the dielectric/ITO film.

Title: Prevention method of marine organism adhesion and device therefor
Inventor: MURAKAMI HIDEO
IPC: A01M29/14
Filed: 1993-12-21
Abstract: PURPOSE:To prevent the adhesion of marine organisms to fixed or moving structures immersed in sea water all the time, by using a waste heat of an engine, etc., without using any repellent such as a ship bottom paint, etc., containing a poisonous material causative of an environmental disruption. CONSTITUTION:An inside surface temperature of a water inlet 20 is kept at 20-60 deg.C, preferably 35-55 deg.C by using secondary cooling water heated by a waste heat of an engine, circulating from a secondary cooling water tank.
