  • Blind rivet
    Patent number: 8430613
    Abstract: A mandrel has an anti-dropping-off portion that is formed between a head and a breakable portion thereof. In the anti-dropping-off portion, a plurality of latching ridges is formed which have peaks that protrude outwardly in the radial direction and frictionally engage with the inner wall surface of a sleeve. The latching ridges are formed in the outer surface of the portion of the mandrel that is between the head and breakable portion thereof, so as to be diagonal relative to the circumferential direction of the outer surface of the mandrel and to cross each other, with the peaks thereof formed in a twill pattern protruding out from the outer surface of that mandrel portion.
    Type: Grant
    Filed: January 27, 2011
    Date of Patent: April 30, 2013

  • Vehicle brake fluid pressure control device with hydraulic booster
    Patent number: 6851762
    Abstract: A hydraulic booster is provided between a M/C pressure and a W/C pressure. The hydraulic booster is composed of a pump and an amplifying piston amplifying the brake fluid amount discharged from the pump. The brake fluid discharged from the amplifying piston is supplied to the W/C via a first pipeline. The brake fluid discharged from the pump is supplied directly to the W/C via a second pipeline. First and a second control valves select the first or the second pipeline as a pressurizing path to the wheel cylinder.
