Title: Manufacture for overwritable magneto-optical recording medium
Inventor: HOSOKAWA TETSUO
IPC: G11B11/10
Filed: 1993-10-15
Abstract: PURPOSE:To obtain the sufficient durability of the recording medium with reference to a repeated reproducing operation and a repeated recording operation by a method wherein a memory layer and a recording layer are formed by a binary simultaneous sputtering operation by using a target composed mainly of a rare-earth metal and a target composed mainly of a transition metal. CONSTITUTION:A magneto-optical recording medium is formed in such a way that an R layer 2, an M layer 3, an I layer 4, a W layer 5, an S layer 6 and a magnetic layer which is composed of four or more Ini layers are formed at least on a substrate 1. In the magneto-optical recording layer, at least the M layer and the W layer out of the M layer, the W layer and the Ini layers are formed by a binary simultaneous sputtering method by using two targets, i.e., a target composed mainly of a rare-earth metal and a target composed mainly of a transition metal. Thereby, the durability of the recording medium with reference to a repeated recording operation and a repeated reproducing operation is enhanced. In addition, since the Ini layers are formed by the binary simultaneous sputtering method, a laser-beam intensity range which makes the recording medium overwritable can be made much wider.

Title: Production of spectacle frame parts made of metal
Inventor: NOMICHI HIROMI
IPC: G02C5/00
Filed: 1991-09-10
Abstract: PURPOSE:To obtain the lightweight metallic frame of spectacles having high strength by forming the metallic frame parts into hollow and thin structures having uniform film thicknesses by using an electrocasting method. CONSTITUTION:The parts of the metallic frame are produced by the electrocasting method. Namely, matrices are produced on the basis of the prototypes of the respective parts of the spectacle frame and the surfaces of the matrices are plated by the electrocasting method. The matrices are subjected to the electrocasting and, therefore, metallic materials having an electrical conductivity or the materials formed with metallic films on their surfaces are used. Since the matrices are removed after the plating, the matrix materials which are easily soluble or meltable are selected. Fusible alloys, brass and synthetic wax subjected to metal plating are conceivable as the matrix materials. These materials are required to be plated at about >=200mum thickness in order to obtain the strength. The hollow and thin frame parts are obtd. by such means. The metal deposited by the electrocasting method is harder than the original metallic materials and has excellent wear resistance, corrosion resistance and mechanical strength.

When the transistor QN is then turned off, the terminal voltage 2V1 across the capacitors C1 and C3 charges a capacitor C2. Therefore, the output voltage VOUT of this DC-DC converter A becomes twice as high as that of the conventional converter. When the converter is made to output the same voltage, the load to the choke coil L and transistor QN become 1/2.
