  • Publication number: 20020137639
    Abstract: Disclosed is a grease sealed bearing for automobile that has the high temperature resistance as well as shear stability, and prevents the noise at low temperature as well as the brittle flaking under high speed rotation and high load. The grease comprises a base oil containing a synthesized hydrocarbon oil and one or more ester oils at a weight ratio of 0.1 to 0.49:0.9 to 0.51; 5 to 30% by weight of a urea based thickener, and 0.1 to 10% by weight of dithiozinc phosphate based on the whole grease. The grease sealed bearing for automobile is obtained by sealing a bearing used in a device driven by an automobile engine with the grease.

  • Patent number: 6447153
    Abstract: A reflector is for reflecting light rays from the light source bulb to set up a brightness intensity distribution pattern. The reflector is separated in a movable reflector part and a fixed reflector part. The movable reflector part has a first separated edge. The fixed part has a second separated edge in opposition to the first separated edge. A driving means is for moving the movable reflector part relative to the fixed reflector part to change a brightness intensity distribution pattern of light rays from the light source bulb. The shading flange is for shading an air gap between the first separated edge and the second separated edge.

  • Patent number: 6252683
    Abstract: A video printing apparatus feeds sheets of printing media from the lower front portion of the apparatus housing and ejects the print media at the upper front portion of the apparatus housing. The apparatus comprises a feed tray to be loaded with printing media, a feeding unit to feed the printing media into the inside of the apparatus, a transport unit to transport the printing media fed by the feeding unit, a switching unit provided between the feeding unit and the transport unit to switch over the transport route of the printing media, at least one detecting unit provided between the switching unit and the transport unit to detect the printing media, a printing unit to transfer printing onto the printing media, an ejection unit to eject the printing media after they have been printed by the printing unit, and an ejection tray to store the printing media ejected by the ejection unit.

  • Publication number: 20010000448
    Abstract: A vehicular head lamp enables rotation of an upper reflector (1) relative to an intermediate reflector (2), thereby changing a dispersed light-distribution pattern (WP) with respect to a fixed reference light-distribution pattern (LP and HP). By causing a lower reflector (3) to rotate relative to the intermediate reflector (2), a collimated light-distribution pattern (SP) is changed with respect to the reference light-distribution patterns (LP and HP). The result of this arrangement is an improvement in visibility when the vehicle negotiates a curve.

  • Patent number: 4982077
    Abstract: A recording format for an optical recording medium having a rectangular data recording region capable of containing n data-bit lines. In the recording format, the data recording region is sectioned into bands having a width corresponding to an appropriate number of data-bit lines to form blocks. Each of the blocks is provided with an identifier to allow the access by block units. Each of the blocks may be formed of a group of data-bit lines and check bit line. Each block may have a plurality of sectors. The blocks may be sectioned by boundary information lines having a specific code pattern.

  • Patent number: 4265977
    Abstract: Paper coating compositions having an improved combination of properties are prepared by admixing, in the normal proportions and by conventional techniques, one or more conventional paper coating pigments with a particular type of synthetic polymer latex. In such compositions, the particular latex employed is alkali-sensitive and is prepared by emulsion polymerizing (A) from about 10 to about 90 parts by weight of a monomer mixture comprising, based upon the weight of such monomer mixture, (1) from about 10 to about 60 weight percent of an ethylenically unsaturated carboxylic acid monomer and (2) from about 40 to about 90 weight percent of a copolymerizable monoolefin compound in the presence of (B) from about 10 to about 90 parts by weight, on a polymer solids basis, of a copolymer latex comprising a monovinylidene aromatic monomer such as styrene and an open-chain aliphatic conjugated diene such as butadiene.
