摘要： An inorganic ion exchanger prepared by kneading a blend of anatase type titanic acid or amorphous titanic acid with sulfuric acid, hydrochloric acid or phosphoric acid and water, extrusion molding the blend, and thereafter, heat treating the extruded product at an elevated temperature. The inorganic ion exchanger has high strength in water and is suitable for use in the removal or the concentration and recovery of injurious or beneficial materials contained in water.

摘要： A disk substrate is supported by a support base formed on a center pin which is vertically movable on a selective basis, a table is set below the disk substrate, and a stamper is positioned on the table by means of a guide ring or the like. A ring-shaped portion of resin which is cured upon radiation of ultraviolet rays is set on the stamper. The center pin is then caused to descend by means of a drive mechanism, to a first position, at which position the disk substrate is on the point of contact with the resin. Then, the disk substrate is caused to descend intermittently in units of very small amounts, to a second position, at which position the entire periphery of the ring-like resin is brought into contact with the disk substrate. From the second position, the disk substrate is made to descend by means of the a load of a weight while, at the same time, the ring-shaped portion of resin is drawn by vacuum suction from its central position, thereby forming on the surface of the stamper a resin layer on which a record, formed on the stamper, is imprinted.

摘要： An optical recording medium is disclosed, which has a substrate and a recording film formed on the substrate. The recording film has a film comprising tin as the main component and passive state-forming metal layers formed on both sides of the tin film. The optical recording medium has a high recording sensitivity, a good signal quality and a high reliability. The optical recording medium is prepared by forming a first passive state-forming metal layer, a film comprising tin as the main component and a second passive state-forming metal layer in sequence on a substrate, and preferably heating the thus-obtained laminate.
