    • A semiconductor device includes an active region with a main semiconductor device section, and a junction-termination region therearound. A first diffusion layer of a second conductivity type is formed in a surface of a first semiconductor layer of a first conductivity type, and extends from the active region into the junction-termination region. A second diffusion layer of the second conductivity type is formed in contact with the first diffusion layer, and extends in the junction-termination region. A first contact electrode is disposed in the active region and in contact with the first diffusion layer, and electrically connected to a first main electrode of the main semiconductor device section. A second contact electrode is disposed in the junction-termination region and in contact with the first diffusion layer, and surrounds the active region. A connection electrode electrically connects the first and second contact electrodes to each other.

    • 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.
    • 具有形成在阀体上的座面的阀门阀,当阀关闭时与阀座接触的流量控制阀具有在支撑构件的中心具有球面中心的假想球面的一部分的形状。 因此,即使轴倾斜,从支撑构件的中心到座面的距离保持恒定,并且阀元件可以没有间隙而位于阀座的周边。 因此,阀泄漏减少。 支撑构件支撑连接到可在轴的轴向方向上移动的阀元件的轴。 支撑构件的中心与阀座的中心对准。 支撑构件在支撑构件的径向方向上的移动被禁止。 因此,支撑构件的中心在径向上不从阀座的中心偏移。 因此,可以防止轴在径向上的位移。 因此,阀元件确实位于阀座上,并且防止阀泄漏。
