  • Patent number: 7164548
    Abstract: A magnetic recording medium and a method of manufacturing the same which serve for stable head behavior and efficient recording of servo information. In each servo area, a magnetic layer is separated into a plurality of servo pattern unit parts for forming a predetermined servo pattern and a plurality of servo pattern gap filling parts patterned to fill gaps between the plurality of servo pattern unit parts partly. The servo pattern unit parts and the servo pattern gap filling parts are formed in different sizes so as to have different magnetic properties.

  • Publication number: 20060081126
    Abstract: An oil ring 1 comprises an annular oil ring body 10 having a pair of rail portions 12 at its axially upper and lower portions and butt ends, and a coil expander 20 assembled in the inner periphery of the oil ring body 10. The cross-sectional profile taken in the radial direction of the outer peripheral sliding surface (f) of the pair of rail portions 12 has a nearly straight region (f1) with a length of equal to or more than 0.05 mm in the center and curved regions (f2) formed on both sides of the straight region (f1).

  • Publication number: 20050214583
    Abstract: A magnetic recording medium having a recording layer formed in a concavo-convex pattern, which can allow a head to have stable flying characteristics. The recording layer is formed in a concavo-convex pattern, and concave portions of the concavo-convex pattern of the recording layer are filled with a non-magnetic material. The relationship of S?3.6×R holds, when R represents a concavo-convex ratio obtained by dividing an area of convex portions in a surface by an area of the concave portions in the surface, and S represents a difference in height between a concavity and a convexity of the surface. In the magnetic recording medium, an arithmetical mean deviation of the assessed profile of the surface is limited to 0.3 nm or more.

  • Patent number: 5971099
    Abstract: A lightweight and inexpensive soundproof material which is reclaimable comprises a thermoplastic resin substrate and a non-woven cloth laminated on a surface of the substrate and made from thermoplastic resin fibers different from the material of the substrate. The assembly of fibers and the substrate are bonded together integrally through a joint interface which is at least partially molten by ultrasonic vibration.

  • Patent number: 5620228
    Abstract: A drawer device or member is provided which is prevented from inadvertently moving of an arm rest at the time of either a sudden stop or very fast acceleration when starting. The drawer device comprises an outer member fixed in the arm rest and an inner member installed so as to be capable of sliding movement into and out of the outer member. A push type lock or open mechanism is positioned between the outer member and the inner member, and regulates movement of the inner member. Also included is a control device, which controls movement of the inner member by preventing release of the lock when the arm rest is in a substantially upright position, and releases the lock when the arm is in a substantially horizontal position.

  • Patent number: 4930048
    Abstract: An air-conditioning control box according to the invention comprises: a casing having a front panel and a rear box, the casing having an inner surface which reflects light at a high efficiency, the front panel having a hole for receiving an air-conditioning control means; a light source mounted in the casing; air-conditioning control means which is inserted in the hole formed in the front panel and which is held to the casing so as to be rotatable or movable; a light transmission member made from a material that transmits light, the light transmission member including a light-incident surface disposed inside the casing and a light-emitting surface disposed along the fringe of the hole; and a shading coating that partially coats a portion of the light-incident surface of the light transmission member which receives a larger amount of light.
