    • A disc brake for a bicycle or the like, which is provided with two arms opposite both surfaces of a disc rotatable with the bicycle wheel, which arms are pivotally supported to a fixed member to be freely swingable with respect thereto and shiftable toward the disc and carry pads directly attached to the arms. At least one of the arm and fixed member is formed of a recess which has a tapered face and receives a rolling member, such as a ball, into the recess. When the arms swing the rolling member rolls along the tapered face so that the arms may be shifted toward the disc and the pads be brought into contact with the disc to thereby exert the braking action.
    • 一种用于自行车等的盘式制动器,其具有与可自行车轮可旋转的盘的两个表面相对的两个臂,所述臂可枢转地支撑在固定构件上,以能够相对于所述固定构件自由摆动并且可向盘移动; 携带垫直接连接在手臂上。 臂和固定构件中的至少一个由具有锥形面的凹部形成,并且将诸如球的滚动构件容纳到凹部中。 当臂沿着锥形表面摆动时,使得臂可以朝向盘移动,并且使垫与盘接触,从而施加制动作用。

    • An induction heating device includes: a rectifying circuit that rectifies an AC power supply; a smoothing capacitor that smooths the rectified output to obtain a DC power supply; a first and a second inverters each composed of a heating coil, a resonance capacitor, and a switching element, and connected to the smoothing capacitor in parallel; a first and a second oscillating circuits that supply drive signals to the switching elements; and a controller that controls drive of the first and second oscillating circuits. The controller alternately drives the first and second oscillating circuits, and controls a drive time ratio of the first and second oscillating circuits so that a power change amount generated every time the drive is switched between the first and second oscillating circuits is not more than a predetermined amount.
