Abstract: Optical material, which was already roughly molded, is deposited into a space defined by a top mold, a bottom mold and a drum mold, and is then heated, pressed and molded, thus providing an optical element. By controlling the rate of plastic deformation of the optical material so as to prevent the material from entering clearance sections between the outside diameter of the top mold or of the bottom mold and the inside diameter of the drum mold, an optical element of high precision with no burr nor strain is provided at low cost.

Abstract: A die for press-molding an optical element with high precision comprises a base material made of a material excellent in heat resistance, heat shock resistance and mechanical strength at high temperature, an intermediate layer formed on the base material and made of a thin film excellent in grinding machinability and cutting machinability, and a surface protective layer formed on the intermediate layer and made of a metal thin film excellent in heat resistance and mechanical strength at high temperature and less reactive to a material of the optical element. Additional thin film may be inserted between the base material and the intermediate layer so as to enhance the adhesion strength between the base material and the intermediate layer. In place of the additional thin film to be inserted, a peripheral flange part of the intermediate layer is removed and thus on the removed peripheral part, the surface protective layer is directly adhered to the base material.

Abstract: An ion generating device generates O2−(H2O)n (where n is a natural number) as negative ions and H+(H2O)m (where m is a natural number) as positive ions, and discharges those ions into the air so that airborne germs are killed through an oxidation reaction by hydrogen peroxide H2O2 or radical hydroxyl OH generated through as an active species a chemical reaction between the negative and positive ions. Satisfactory sterilization is achieved when the negative and positive ions are generated in such a way that the concentrations of the negative and positive ions are both 10,000 ion/cc at a distance of 10 cm from the point at which they are generated.
