  • Contiguous colliquefaction forming a surface film for a composite strip
    Patent number: 6849310
    Abstract: A contiguous surface film for a composite strip, such as a weatherseal is disclosed, wherein the surface film is formed of a colliquefied powder coating. The surface film can be located on a carrier, sealing or trim portion of the weatherseal, wherein the surface film can be colored, and selected to provide a desired surface characteristic such as reduced coefficient of friction.

  • Magnetic recording medium and process for producing the same
    Patent number: 6753077
    Abstract: A magnetic recording medium including a substrate and formed on the substrate a maghemite thin film having a surface roughness represented by a center line mean roughness Ra of 0.1 to 1.0 nm, and a coercive force squareness S* value of not less than 0.50. This magnetic recording medium exhibits excellent magnetic properties, especially, coercive force squareness S* value and a more enhanced surface smoothness.

  • Conductive blade
    Patent number: 6524695
    Abstract: A conductive blade includes a blade member formed of an electrically conductive rubber, and an electrically conductive holder. The blade member has one widthwise end portion serving as a free end portion and the other widthwise end portion serving as a bonding end portion. One end of the free end portion is brought into contact with a subject member. The holder is bonded to the bonding end portion of the blade member over the length of the blade member. A conductive layer formed of a conducting filler and an elastomer is provided for connecting the end face of the bonding end portion of the blade member and a portion of the holder which is adjacent to the end face of the bonding end portion.

  • Magnetic recording medium and process for producing the same
    Patent number: 6821618
    Abstract: A magnetic recording medium exhibiting a high coercive force and excellent squareness having a substrate, an underlayer formed on the substrate, and a spinel-type iron oxide thin film with maghemite as a main component formed on the underlayer. The spinel-type iron oxide thin film has a thickness (t) of 5 to 50 nm, is constituted by grains having an average grain size (D) of 5 to 30 nm, standard deviation of sizes of grain of not more than 4 nm and a ratio (D/t) of the average grain size (D) to the thickness (t) of less than 1.0, exhibits a coercive force of not less than 159 kA/m (2,000 Oe) and a coercive squareness ratio S* of not less than 0.5:1 in a longitudinal recording medium or a squareness ratio not less than 0.75:1 in a perpendicular recording medium.
