摘要: In a hermetically circulating absorption type refrigerator including a regenerator, a condenser, an evaporator, an absorber and a heat exchanger, the regenerator has an absorbing solution heating tube flux provided between tube plates. The tube plates are encased within a shell of the regenerator. Non-soluble electrodes are arranged between each of the tube plates and the shell. Then, an anti-corrosive current is made to flow through at least one of an end portion of the heating tube, the tube plates and the shell to thereby enhance the anti-corrosion effect together with an anti-corrosive agent or inhibitor.

摘要: A process for the partial hot dipping of a long steel strip is disclosed which comprises forming an oxidation-inhibiting film, oxygen-impermeable and thermally stable in a hot-dipping bath, which film is produced by the chemical reaction of an iron content in the steel strip with an oxidation inhibiting film-forming agent, such as an inorganic phosphoric acid compound, on a predetermined area of the steel strip surface, forming, as required, an intermediate layer comprising an inorganic binder, such as water glass, on the resulting film, forming a carbon-containing, plateing-stopping film as a top coat on the intermediate layer, and hot dipping the steel strip.
