    • There is disclosed a sealing material for an ant groove, wherein the sealing material is easy to fit to the ant groove and little involves a phenomenon such that the sealing material unfavorably slips out of the ant groove in the form of remaining fixing to the opposite member when the sealed place is opened, and wherein the sealing material can exercise the good sealing function. The sectional shape of the sealing material has: a straight bottom edge 34 which is disposed on a bottom face of the ant groove 12; an arched convex edge 31 which contacts with the other member 20; a first projecting edge 33 which projects outside; a concave inlet portion 39; a second projecting edge which is composed of straight lines 35, 36 that project outside; a straight sloping edge 38; and at least one corner portion 37a-c which is constituted in the range of from the straight bottom edge 34 via the second projecting edge 35, 36 to the sloping edge 38.
    • 公开了一种用于蚂蚁槽的密封材料,其中密封材料易于装配到蚂蚁槽,并且很少涉及这样的现象,使得密封材料不利地从保持固定到相对构件的方式滑出蚂蚁槽 当密封的地方打开时,并且其中密封材料可以运行良好的密封功能。 密封材料的截面形状具有:设置在蚂蚁槽12的底面上的直的底部边缘34; 与另一个构件20接触的拱形凸缘31; 突出外侧的第一突出边缘33; 凹入口部分39; 由外部突出的直线35,36构成的第二突出边缘; 直的倾斜边缘38; 以及至少一个角部37a-c,其通过第二突出边缘35,36从直线底边缘34到倾斜边缘38构成。

    • Method for producing at low cost bellows which show high durability even when used in a quite reactive atmosphere. The 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的范围内 ×1012,由此在未处理的波纹管的表面上形成Al 2 O 3钝化膜。
