    • Method for producing at low cost bellows which show high durability even when used in a quite reactive atmosphere. A method for manufacturing bellows includes the steps of: I: forming an untreated bellows from a flat base plate, the base plate including 15 to 30 wt % of Cr, 5 to 40 wt % of Ni, 0.9 to 6 wt % of Al, less than 1 wt % of Mo, less than 0.1 wt % of Mn, less than 0.1 wt % of C, less than 0.1 wt % of S, less than 0.1 wt % of P and a balance of Fe and an unavoidable impurity (relative to 100 wt % of the base plate); and II: heating the untreated bellows at a temperature of 750 to 895° C. in an atmosphere which contains water and hydrogen and in which the volume ratio of hydrogen to water (H2/H2O) is in the range of 2×103 to 1×1012, thereby forming an Al2O3 passivation film on a surface of the untreated bellows.
    • 低成本波纹管的生产方法,即使在相当活跃的气氛中使用也显示出高耐用性。 制造波纹管的方法包括以下步骤:I:从平的基板形成未经处理的波纹管,基板包括15至30重量%的Cr,5至40重量%的Ni,0.9至6重量%的Al, 小于1重量%的Mo,小于0.1重量%的Mn,小于0.1重量%的C,小于0.1重量%的S,小于0.1重量%的P和余量的Fe和不可避免的杂质(相对 至100重量%); 和II:在含有水和氢的气氛中在750至895℃的温度下加热未处理的波纹管,其中氢与水的体积比(H 2 / H 2 O)在2×10 3至1×10 12的范围内,从而 在未处理的波纹管的表面上形成Al 2 O 3钝化膜。

    • A lens array sheet, a transparent screen using the same, and a rear-projection display device are provided in which it is possible to control a perspective angle for the image in both a horizontal direction and a vertical direction without causing a problem in that a gain (brightness) of a light is reduced by an optical absorption and an S/N ratio is reduced by an increased white dispersion.A first lens array 18 and a second lens array 20 which are formed by disposing a plurality of half-cylindrical lenses 17, 19 in parallel on a common plain (a surface of a base member layer 13a) such that longitudinal directions of the cylindrical lenses 17, 19 should be orthogonal to each other. Unified lens array layer 13b and a shading layer 16 in which a section through which a light does not transmit is formed on a focal plain of the lens array layer 13b form a lens array sheet. Furthermore, fresnel lens are combined so as to form a transparent screen.

    • In a vacuum gate valve, a seal member for sealing a gate opening part is bonded to an outer edge part of a planar seal plate that is disposed in such a manner that the planar seal plate is opposed to a valve seat surface of the gate opening part and comes into contact with the valve seat surface. The seal member includes a vacuum seal part that is located on a side farther from the gate opening part and maintains the sealability of the gate opening part when the gate opening part is closed, and also includes a radical seal part that is located on a side closer to the gate opening part and that prevents the seal member from being affected by a treatment gas in the gate opening part when the gate opening part is closed. The vacuum seal part is made of a rubber elastic body, and the radical seal part is configured by providing a radical resistant body that is provided with an excellent radical resistance on the rubber elastic body.
    • 在真空闸阀中,用于密封闸门开口部的密封构件被接合到平面密封板的外边缘部分,该平面密封板的设置方式使得平面密封板与门开口的阀座表面相对 并与阀座表面接触。 密封构件包括真空密封部,该真空密封部位于离开门开口部更远的一侧,并且当开口部闭合时保持开口部的密封性,还包括位于侧面的自由度密封部 更靠近闸门开口部分,并且当门打开部分关闭时防止密封件受到门开口部分中的处理气体的影响。 真空密封部分由橡胶弹性体制成,并且通过在橡胶弹性体上设置具有优异的自由基阻力的自由基体,构成自由基密封部。
