摘要： Disclosed is a process for forming an electrostatic latent image on a recording element having a dielectric layer superposed on a conductive electrode. In the first step of this process, the recording element and a xerographic sensitive element having a photoconductive layer also superposed on a conductive electrode are charged with the same polarity. In the second step, the photosensitive element is brought into virtual contact with the recording element so that the charged surface of the photoconductive layer in the photosensitive element is in face-to-face relationship with the charged surface of the dielectric layer in the recording element. In the third step, an external voltage is imposed between the two conductive electrodes, said voltage being of at least a magnitude for producing an electric field causing breakdown of minute air-gaps present between the contacted surfaces of the photosensitive element and the recording element and, before the completion of the external voltage imposition, an optical image is projected onto the photoconductive layer in the photosensitive element.

摘要： A magnetic recording medium conventionally utilizes the in-plane magnetization mode, but recently the perpendicular magnetization mode utilizing the perpendicular anisotropy of an hcp cobalt alloy layer, in which the C axis is oriented perpendicular to the layer surface, has been proposed. The known perpendicular magnetic recording medium is produced by means of RF sputtering and comprises a Permalloy layer, as layer of a low coercive-force material, between the nonmagnetic base and the hcp cobalt alloy layer. The perpendicular anisotropy attained by the present invention in very excellent and is superior to that of a perpendicular recording medium having no Permalloy layer because a Co-Ta alloy is used as the layer of a low coercive-force material.

摘要： A magnetic recording disk cartridge includes a casing having upper and lower halves mated together to define a planar spacing in which a magnetic recording disk supported by a hub member is rotatably held, and fluctuation suppressing ring members are disposed within the casing to be axially spaced from one another via at least an outer peripheral portion of the magnetic recording disk. The fluctuation suppressing ring members aerodynamically maintain the magnetic recording disk at an intermediate position in the planar spacing of the casing during the rotation of the magnetic recording disk.

摘要： Magnetic recording medium conventionally utilizes the in-plane magnetization mode, but, recently, the perpendicular magnetization mode utilizing the perpendicular anistropy of an hcp cobalt alloy layer, in which C axis is oriented normal to the layer surface, is proposed. The known perpendicular magnetic recording medium has been produced by an RF sputtering, but such medium is of too low flexibility to use it in the form of a magnetic tape. In addition, the production rate of the perpendicular magnetic recording medium by RF sputtering is very low.The perpendicular magnetic recording medium is very flexible due to particle pattern (FIGS. 10, 12 and 13) completely distinct from the conventional columnar pattern (FIGS. 8 and 11). In addition, the production rate is high, because the base (20) is located beside a space between the targets (T.sub.1, T.sub.2) of a sputtering device and further the magnetic field is generated perpendicularly to the sputtering surfaces (T.sub.1s, T.sub.2s) by a field coil (31) or magnets (32, 33). The present invention makes it possible to commercially produce the perpendicular magnetic recording medium, especially in the tape form.

摘要： Disclosed is a facing-targets-type sputtering apparatus and method capable of forming a metal film under the conditions of low gas pressure and low discharge voltage. An opening is formed in each of two facing side faces of a vacuum chamber vessel or in each of two facing side faces of a box-type discharge unit attached to an opening portion of a vacuum chamber vessel. The two openings are covered by a pair of cooling blocks. Each cooling block holds a target facing a discharge space. Magnetic field generation means is disposed so as to surround each target and operative to generate a magnetic field that surrounds a discharge space provided between the paired targets. Electron reflection means is disposed above the exposed surface of each target along the periphery of the target. A DC power and a high-frequency power are applied between the vacuum chamber vessel and the targets.

摘要： Disclosed is a method for forming a thin-film layer, such as a metallic film or a transparent conductive film, on a functional organic layer formed from an organic compound, by means of a sputtering method performed at a low discharge voltage and a low gas pressure, without imparting any damage to the surface of the organic layer. The thin-film layer is formed by use of a facing-targets-type sputtering apparatus including a pair of facing targets disposed a predetermined distance away from each other; an electron reflection electrode disposed on the periphery of each target; and magnetic field generation means disposed at the sides of each target. The magnetic field generation means generates a magnetic field extending from one target to the other so as to surround a confinement space provided between the paired targets, as well as a magnetic field having a portion parallel to the surface of each target in the vicinity of a peripheral edge portion of the target. When an AC-DC power containing a DC component and a high-frequency component is supplied as a sputtering power to the apparatus, the thin-film layer can be formed at a lower discharge voltage and a lower gas pressure.
