    摘要： A flow control valve having a seating surface formed on a valve element to contact a valve seat when the valve is closed has a shape of a part of a hypothetical spherical surface having a spherical center at a center of a supporting member. Therefore, the distance from the center of the supporting member to the seating surface is kept constant, and the valve element can be seated at a periphery of the valve seat without a gap, even if the shaft is inclined. Thus, the valve leakage is reduced. The supporting member supports a shaft connected to the valve element movable in an axial direction of the shaft. The center of the supporting member is aligned with a center of the valve seat. Movement of the supporting member in a radial direction of the supporting member is prohibited. Therefore, the center of the supporting member is not displaced from the center of the valve seat in the radial direction. Accordingly, the displacement of the shaft in the radial direction can be prevented. Therefore, the valve element is certainly seated on the valve seat, and the valve leakage is prevented.

    摘要： An accelerator capable of detecting a turning angle of an accelerator pedal with high accuracy includes a bearing part, an urging part, an accelerator pedal, a stopper, and a turning angle sensor. The accelerator pedal has a turning shaft supported by the bearing part and is turned forward when a depressing force is applied thereto and is turned reversely when the urging force of the urging part is applied thereto. The stopper abuts against the accelerator pedal to limit the reverse turn of the accelerator pedal and substantially simultaneously guides the accelerator pedal in a direction equivalent to that which the urging force is applied. The turning angle sensor detects the turning angle of the accelerator pedal.

    摘要： A pedal module includes a double coil spring, a pedal, and a damping part. The double coil spring includes an outside coil and an inside coil. The pedal turns in a forward direction when a depressing force is applied thereto and turns in a reverse direction when a restoring force of the double coil spring is applied thereto. The damping part has an inserting portion disposed between the outside coil and the inside coil. The inserting portion includes a middle portion and a first side end portion disposed relative to each other in a width direction that corresponds to a circumferential direction of the double coil spring. The middle portion crosses a radial axis of the double coil spring and protrudes beyond the first side end portion toward an axial end of the double coil spring.

    摘要： In an idle speed control valve, an adjusting screw is inserted into a hole of a valve body and passes through a center of a coil provided in the valve body. The adjusting screw has a ring-shaped flexible projection on its outer periphery between a head portion and a threaded portion thereof to prevent a sealing material from entering. An outer diameter of the projection is equal to or slightly larger than an inner diameter of the hole. Therefore, when the adjusting screw is inserted into the hole, a peak of the projection contacts an inner wall of the hole. The projection may be integrally molded with the adjusting screw. A ring-shaped projection may be provided on a thin wall portion of the adjusting screw.

    摘要： A semiconductor device such as an IGBT having trench gates in a form of stripes, and manufacturing method, wherein concentration of stresses in only a single direction is relieved and the generation of a leakage current and crystal defects in the IGBT is prevented. In one embodiment, the inside of a terminal area of an IGBT is divided into a single gate pad area and plural element areas by a wiring area. The respective element areas are arranged in such a manner that the directions of trench gates formed in the respective element areas cross at right angles with respect to the directions of trench gates of respective adjacent element areas.
