    • 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.
    • 在形成合成电路的反向导通半导体器件中,可以将高于集电极的正电压的正电压施加到发射极。 在这种情况下,在形成有返回二极管的反向导通半导体器件的区域中,体接触区域用作阳极,漂移接触区域用作阴极,并且电流从阳极流到阴极。 此时当沟槽栅电极施加具有比集电极电位低的电压的电压时,在阴极内产生p型载流子,在返回二极管内增加载流子数量。 结果,返回二极管的正向压降降低,并且可以减少电力的恒定损失。 在使用其中开关元件和返回二极管反向并联连接的组合电路的电源装置中,电力损耗可以减小。

    • To block the transmission to a vehicle body side of the vibration due to the cavitation phenomenon occurred in a primary liquid chamber so as to prevent the generation of noises, at the same time, to make the device compact, and to improve the fitting accuracy to obtain the reliable positioning, a first metallic fitting and a second metallic fitting are connected by an insulator. A primary liquid chamber and a secondary liquid chamber formed inwardly are partitioned by a partition member and communicated therebetween by an orifice passage. The partition member is floatingly supported between an extended portion of the insulator and an outer peripheral thick wall portion of a diaphragm, and the tuning is performed to generate the rigid resonance at the predetermined frequency. An outer ring is provided in the outer peripheral thick wall portion so as to be securely fixed by a fixing portion formed by bending an end of an outer cylindrical fitting. The floatingly supporting structure does not become large-sized and complicated since the partition member is simply floatingly supported.
    • 为了阻止由于在主液室中发生的气蚀现象而导致的车体侧的传递,以防止产生噪声,同时使得该装置紧凑,并且将装配精度提高到 获得可靠的定位,第一金属配件和第二金属配件通过绝缘体连接。 向内形成的主液室和二液室由分隔构件分隔开,并通过孔通道连通。 分隔构件浮动地支撑在绝缘体的延伸部分和隔膜的外周厚壁部分之间,并且进行调谐以产生预定频率的刚性谐振。 在外周厚壁部分设置有外环,以便通过弯曲外圆筒形配件的端部而形成的固定部分可靠地固定。 由于分隔构件被简单地浮动地支撑,所以浮动支撑结构不会变得大而复杂。
