Abstract: An information processing device is described which is capable of easily changing a current application to new one during inputting data for said application through a composite input screen and of effectively using the input data between applications. Two or more kinds of application programs are stored in a store means such as ROM. Every application mode may have respective input items stored as adapted record structure in a store means such as RAM. The device is provided with a reading means for reading data inputted and stored in each application mode and a correcting means for correcting the read-out data and has a function for displaying data inputted or corrected on a display screen.

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.
