摘要： An IGBT has an emitter region, a top body region that is formed below the emitter region, a floating region that is formed below the top body region, a bottom body region that is formed below the floating region, a trench, a gate insulating film that covers an inner face of the trench, and a gate electrode that is arranged inside the trench. When a distribution of a concentration of p-type impurities in the top body region and the floating region, which are located below the emitter region, is viewed along a thickness direction of a semiconductor substrate, the concentration of the p-type impurities decreases as a downward distance increases from an upper end of the top body region that is located below the emitter region, and assumes a local minimum value at a predetermined depth in the floating region.

摘要： In a reverse conducting semiconductor device, which forms a composition circuit, a positive voltage that is higher than a positive voltage of a collector electrode may be applied to an emitter electrode. In this case, in a region of the reverse conducting semiconductor device in which a return diode is formed, a body contact region functions as an anode, a drift contact region functions as a cathode, and current flows from the anode to the cathode. When a voltage having a lower electric potential than the collector electrode is applied to the trench gate electrode at that time, p-type carriers are generated within the cathode and a quantity of carriers increases within the return diode. As a result, a forward voltage drop of the return diode lowers, and constant loss of electric power can be reduced. Electric power loss can be reduced in a power supply device that uses such a composition circuit in which a switching element and the return diode are connected in reverse parallel.

The cross sections of the protrusion (13a) and the protrusion (13b) are shaped such that a center portion of the roller main body (11) in the direction of the shaft is a boundary (14), and that on the left side of the boundary (14), a vertex (131a) is displaced to the left side from the perpendicular bisector (133a) of an opposite side (132a) whereas on the right side of the boundary (14), a vertex (131b) is displaced to the right side from the perpendicular bisector (133b) of an opposite side (132b). In this way, in a metallic movement roller that moves a strung endless belt, the winding movement and the like of the belt can be prevented, and the belt can be intentionally moved in a specific direction.

摘要： A partition member is provided with an elastic body for absorbing hydraulic pressure fluctuation of the primary liquid chamber and a frame member for supporting an outer circumferential portion of the elastic body while aiming to prevent the rotation of the elastic body. A relief aperture communicating between the primary liquid chamber and the secondary liquid chamber is located on the outer circumferential side in the elastic body supporting region of the frame member. A relief valve for opening and closing the relief aperture is integrally formed on the outer circumferential side of the elastic body. The relief valve is formed of a pair of right and left relief valves. A width across flat sections are formed on a thick-walled outer circumferential section of the elastic body which is located between the right and left relief valves, such as to serve as a detent means.
