Abstract: In an anti-reflection silicon oxide and indium-tin oxide (ITO) multilayer film, the uppermost silicon oxide film (25) is thicker than the immediately underlying ITO film (24). An anti-reflection film comprises a multilayer of silicon oxide and indium-tin oxide (ITO) films (21, 22) on a base film (11), the uppermost silicon oxide film (25) being thicker than the immediately underlying ITO film (24). An Independent claim is also included for production of the above anti-reflection film. Preferred Features: The lowermost film (21), adjacent the base film (11), is a SiOx film (x = 0.5-1.9) which is deposited while controlling the degree of oxidation of silicon by measuring the light absorption of the film (21). Prior to forming the lowermost silicon oxide film (21), the base film (11) is subjected to a surface activation treatment by glow discharge using an aluminum electrode. All the films are formed using a dual magnetron sputtering system.

Abstract: PROBLEM TO BE SOLVED: To provide a filter hardly attaching dirts such as dirts of the hands and scale, making the dirt inconspicuous, easy to remove hardly damaging the surface because of being capable of easily sliding, and durable to wear. SOLUTION: A coating composition containing an alkoxysilane compound having a perfluoropolyether group represented by general formula Rf COR1 -R2 -Si(OR3 )3 (in the formula, Rf represents a perfluoropolyether group, R1 usually represents an atom or an atomic group of O, NH, S or the like, R2 represents an alkylene chain, and R3 represents an alkyl group.) is applied to the surface of a reflection preventing film of a single layer or a multilayer whose surface layer mainly comprises silicon dioxide formed on a glass substrate, then dried at 100 deg.C or lower to obtain a filter having reflection preventing property.

Abstract: A magnetic transducer head in which the magnetic core elements of ferromagnetic oxides are sliced obliquely across the junction surface of the core elements, ferromagnetic metal thin films are formed on the resulting inclined surfaces by employing a physical vapor deposition, and the core elements are placed with the respective ferromagnetic metal thin films abutting to each other for defining a magnetic gap therebetween, wherein the improvement consists in that said inclined surfaces with the ferromagnetic metal thin films formed thereon are inclined at a preset angle with the magnetic gap forming surface, in that non-magnetic films having high-hardness are interposed between the ferromagnetic oxide and the ferromagnetic metal thin films, and in that said ferromagnetic metal thin films and the oxide glass fillers are provided on the tape abutment surface by the intermediary of the non-magnetic film having high-hardness. The provision of the non-magnetic film having high-hardness between the ferromagnetic oxide and the ferromagnetic metal thin film is effective to inhibit the reaction otherwise occurring between the oxide and the films, while positively preventing the formation of the boundary layer with inferior magnetic properties. Likewise, the provision of the non-magnetic film having high-hardness between the ferromagnetic metal thin film and the oxide glass is effective to prevent the erosion of the film by the molten glass, while also improving the molten glass fluidity. It should be noted that the non-magnetic films having high-hardness may be provided on the interface only between the core elements and the metal thin films or on the interface only between the metal thin films and the oxide glass.
