  • Potassium titanate powder, method for producing same, friction modifier, resin composition, friction material, and friction member
    Patent number: 11772982
    Abstract: Provided is a potassium titanate powder that can avoid safety and health concerns and concurrently, during use in a friction material, can give excellent frictional properties. A potassium titanate powder is a powder formed of bar-like potassium titanate particles having an average length of 30 ?m or more, an average breadth of 10 ?m or more, and an average aspect ratio of 1.5 or more, wherein the bar-like potassium titanate particles are represented by a composition formula K2TinO2n+1 (where n=5.5 to 6.5).
    Type: Grant

  • Display device with destaticizing elements and an electrostatic pulse delaying element connected to each of the destaticizing elements
    Patent number: 6088073
    Abstract: A pair of destaticizing elements and a resistive element for delaying an electrostatic pulse are provided between a short-circuiting line short-circuiting a plurality of data lines and an upper end portion of each of the data lines. When a short electrostatic pulse is applied to an upper end portion of one data line from the outside, the leading edge of the pulse is made gentle by the resistive element. As a result, the destaticizing element can work well in response to even the short electrostatic pulse.
