  • Patent number: 8277874
    Abstract: A manufacturing method of a magnetic recording medium, the magnetic recording medium having a structure where plural magnetic recording areas and isolation areas in a magnetic recording layer are formed on a non-magnetic substrate, the isolation areas being configured to magnetically isolate the magnetic recording areas, the manufacturing method includes a step of forming the magnetic layer on the non-magnetic substrate, the magnetic layer being made of a hard magnetic material having a magnetic coercive force whereby magnetic recording is impossible; and a step of performing ion implantation partially at positions corresponding to the plural magnetic recording areas of the magnetic layer so that the magnetic recording areas are formed by reducing the magnetic coercive force in the positions of the ion implantation to a magnetic-recordable magnetic coercive force, and allowing the isolation areas to maintain the magnetic coercive force whereby magnetic recording is impossible.

  • Publication number: 20120008913
    Abstract: There is provided a system configured to prevent recording contents of various broadcasting schemes from being recorded together on a single recording medium while supporting various broadcasting schemes. An optical disc used here can record a digital stream complying with a predetermined digital broadcasting scheme and including specific information APP_NAME corresponding to a broadcasting scheme to be recorded. The broadcasting scheme to be recorded is checked. If another digital stream has already been recorded on the optical disc, its broadcasting scheme is detected from APP_NAME, and is compared with that of the stream to be recorded. If these broadcasting schemes are different, recording is aborted.

  • Patent number: 7855480
    Abstract: An AC generator, referred to as an alternator, is mounted on an automotive vehicle for supplying electric power to an on-board battery and other electric loads. The alternator includes a rectifier device for rectifying alternating current to direct current. The rectifier is composed of a minus-side heat-radiating plate on which six minus-side rectifier elements are mounted and a plus-side heat-radiating plate on which six plus-side rectifier elements are mounted. Each rectifier is mounted on the heat-radiating plate in the same manner, i.e., by forcibly inserting the rectifier element into a mounting hole formed in the heat-radiating plate. A disc portion of the rectifier element has an outer peripheral surface on which knurls are formed. The outer peripheral surface having the knurls is tapered so that the disc portion is easily inserted into the mounting hole while establishing a firm grip and a good heat-conductive contact between the rectifier element and the heat-radiating surface.
