Abstract: A disk brake device has a rotor having a braking surface, a caliper, an outer pad and an inner pad each disposed to face the braking surface, and a braking operation mechanism which performs an operation of pressing the two pads against the braking surface. The braking operation mechanism includes a base plate, a wedge plate which holds the inner pad, a first movement conversion mechanism which moves the wedge plate in a direction perpendicular to the braking surface, while moving the wedge plate to slide relative to the base plate in a rotating direction of the rotor in parallel to the braking surface, an electric motor unit which outputs a rotational driving force, and a second movement conversion mechanism which moves, using the rotational driving force of the electric motor unit, the wedge plate to slide in the rotating direction of the rotor in parallel to the braking surface.

Abstract: A fuel cutoff valve has a housing defining therein a float chamber and a float disposed in the float chamber. The housing defines a connection passage positioned above the float chamber and fluidly connecting the float chamber with outside of the housing and a hole positioned below the fluid chamber fluidly connecting the float chamber with outside of the housing. The float has a valve part that is configured to close the connection passage and defines therein a first passage passing through the float in a vertical direction and a second passage extending from a part of the first passage to an outer surface of the float in a substantial horizontal direction.

Abstract: A method, system, and computer program product for protecting computer users from Web sites hosting computer viruses and for protecting Web hosting systems from hosting Web pages that contains links to computer viruses. a method for protecting users from Web sites hosting computer viruses comprises the steps of: receiving information identifying a Web page selected for access by a user, determining whether the Web page is hosted by a Web site that is included in a database of Web sites related to computer viruses, and allowing access to the Web page based on whether the Web page includes a link to a Web site that is included in the database.

Abstract: A burst phase detection circuit is provided for detecting a phase difference between an input burst signal having a predetermined phase relation with a carrier of a modulated color signal and a sampling pulse. The circuit detects such phase difference based upon a digital signal obtained by demodulating the color signal in accordance with a demodulation axis of one of first and second color difference signals of the color signal. The circuit includes a first sampling circuit which samples a value of the digital signal during an interval of the burst signal within a first horizontal line period of the color signal, and a second sampling circuit for sampling a value of the digital signal during an interval of the burst signal within a second horizontal line period of the color signal. A digital adding circuit is provided for adding the values of the digital signal sampled by the first and second sampling circuits to produce an addition signal.
