    • A recording medium including a resin substrate having a first thermal expansion coefficient, a center hole, a first surface, and a second surface opposite to the first surface, a recording layer formed on the first surface of the resin substrate and having a recording region, an inner nonrecording region formed inside the inner periphery of the recording region, and an outer nonrecording region formed outside the outer periphery of the recording region, and a protective layer formed on the second surface of the resin substrate except an inner peripheral region having a predetermined range from the center hole, the recording region, and the outer nonrecording region. The thermal deformation suppressing layer has a second thermal expansion coefficient smaller than the first thermal expansion coefficient.

    • A backflow prevention valve includes a cylindrical case member having a plurality of holes formed in an upper end at a periphery thereof, a valve member disposed in the case member to be movable in an axial direction thereof, an urging device disposed in the case member for urging the valve member upwardly, and a liquid inflow pipe extending outwardly from the case member. The valve member includes a sealing portion at an upper surface thereof for contacting a peripheral edge of an inflow opening to close the same, and a plurality of guiding arms provided on a peripheral edge of an upper surface of the valve member. The guiding arms are slidably disposed in the holes so that the valve member is supported and guided by the guiding arms passing through the holes.
    • 防回流阀包括:圆筒形壳体,其具有形成在其周边的上端的多个孔;阀构件,其设置在壳体构件中,以沿其轴向方向可移动;推动装置,设置在壳体中, 向上推动阀构件,以及从壳体向外延伸的液体流入管。 阀构件包括在其上表面处的密封部分,用于接触流入开口的周边以封闭流体,并且设置在阀构件的上表面的周缘上的多个引导臂。 引导臂可滑动地设置在孔中,使得阀构件由通过孔的引导臂支撑和引导。
