Abstract: The present invention provides a low-temperature plasma generator as an electric discharger which is used for discharging electricity in dry air, humid air or water, thereby removing an offensive odor, sterilizing bacteria, purifying water and so on. In the low-temperature plasma generator, rod electric conductors are inserted in through-holes formed in rod ceramics dielectric members and extending in longitudinal directions thereof, both ends of the electric conductors and the dielectric members are integrally joined and sealed by glass or an inorganic or organic adhesive, so as to constitute a plurality of electrodes, and the electrodes are connected to each other through the ceramics dielectric members in line-contacted relation.

Abstract: A process for manufacturing zinc-silica composite plated steel performed by electrolyzation in a galvanization bath containing fine grains of silica, particularly colloidal silica fine particles. Surfactant having cationic property, such as polyoxyethylenelaurylamine or dodecyltrimethylammonium chloride is further added to the galavinization bath so that a zinc-silica layer is formed over the steel. The plated steel surfaces are further treated with a silane coupling agent, such as gamma-aminopropyltriethoxysilane. The steel plated with zinc-silica composite thus obtained has excellent resistance against corrosion and adhesion to organic paints or organic adhesives. The steel is suitable for various steel members and sheet iron for automobile bodies and parts which require high corrosion resistance.
