Abstract: The electrostatic printing method of the present invention comprises arranging and adhering an original plate which is composed of an electrode and a plate layer having built-in a letterpress, intaglio plate, or gravure plate pattern or a mask sheet having ion-permeable openings on one or both sides of an image receiving sheet having an electrode and an image receiving layer, and forming a predetermined electrostatic pattern on the image receiving layer of the image receiving sheet by applying a voltage between the electrode of the original plate and the electrode of the image receiving sheet or by performing ion irradiation through the mask sheet.

Abstract: A magnetic head assembly for a flexible magnetic disk drive unit has a magnetic recording and retrieving head for carrying out magnetic recording onto and retrieving from a metallic thin-film type flexible magnetic medium rotating about a center of the medium by coming into contact with the medium at a contact position, a first group of non-magnetic supporting pads arranged to support a plurality of positions of the flexible magnetic medium and disposed so as to surround the contact position, and a second group of non-magnetic suppressing pads in contact with a different plurality of positions of the flexible magnetic medium outward of the plurality of supporting positions so that the suppressing pads suppress any undulation of the flexible magnetic medium during rotation of the medium.

Abstract: A method and apparatus for producing a thin film, such as a magnetic thin film and a metallic thin film on a substrate, such as plastic film, by the employment of a pair of opposed targets spaced apart from one another in a vacuum sputtering gas atmosphere, and magnetic field generating units for generating the perpendicular magnetic field extending perpendicularly to the surface of the targets for confining plasma in the space, and a reflecting electrode arranged adjacent to and in front of the magnetic field generating units and around the periphery of the targets for reflecting electrons toward the space between the opposed targets. The magnetic field generating units are arranged around the outer periphery of each of the opposed targets, and are capable of generating an auxiliary magnetic field for capturing the electrons.
