Abstract: PURPOSE:To obtain a smooth surface by applying a high-frequency bias voltage to a substrate and selectively resputtering a film grown on the projecting parts of the substrate in the stage of forming a high permeability magnetic film on the substrate by a sputtering method. CONSTITUTION:Ar is introduced into a vessel 8 to maintain a prescribed vacuum degree therein. A high-frequency voltage is impressed from a power source 3 to a target 1 to generated plasma and a high permeability Fe-Ni alloy film is formed on the Al alloy substrate 4 formed by subjecting the surface to an alumite treatment from Fe-Ni 2. Electrons from the plasma are accumulated in the substrate and the same state as the state in which a negative bias voltage is impressed is attained when the high-frequency voltage is impressed from a power source 6 to a substrate holder 5. The Ar<+> ions in the plasma arrive at the substrate and balance near the substrate 4. The average negative DC bias is thus determined. The film grown on the projecting parts of the substrate is selectively resputtered by the Ar<+> ions arriving at the substrate, by which the surface is smoothed and the vertical magnetic recording medium having a good surface characteristic is obtd. The spacing quantity between a magnetic head and the medium is decreased and the substantial reproduction voltage is obtd.

Subsequently, this preform is brought into contact with a fluid of a material (carbon dioxide, ethane, etc.) forming a fluid in the supercritical state for about 2-5hr, by which the molding auxiliary is removed so that it remains by about 10-40wt.% based on the preform. By this method, the preform free from the disorder of short-fiber orientation and also free of cracking, bulge, etc., can be obtained. Further, the molding auxiliary remaining in the preform is removed in a preform-preheating stage before casting at the time of manufacturing a metallic composite material.

Abstract: PURPOSE: To record and store an image by exposing a recording material to optochemically active rays according to the image, making transfer from the recording material into a receptor material from the recording material and forming a luminescent latent image inside, and exposing the latent image to rays. CONSTITUTION: An X-ray source 1 emits X rays 2 that are modulated by the internal organization of a man 3 whose X-ray photograph is taken. The modulated X-ray beams hit against an X-ray conversion screen 4 and a reverse side X-ray conversion screen 5. Both screens 4 and 5 emit optically active rays that are absorbed by a recording material in the form of a web 6. Optically active rays that are absorbed in the web 6 form a luminescent latent image inside. The light stimulus of the luminescent latent image obtained in the web 6 is performed by laser beams emitted by a laser device 8. A light deflection device 9 deflects laser beams so that laser beams hit against the web 6 in linear operation format while the web 6 is being wound onto a take-up roll 10. A photo detector 11 receives fluorescence separated from the stimulus light.
