    Abstract: A high vacuum housing with a first and second housing part and in which the housing parts are secured together to form an interior housing chamber. In order to seal the housing parts, an annular outwardly extending sealing ring having a flat radial surface is formed on one of the housing parts. An annular alignment recess is formed on the other housing part which registers with and receives the alignment ring. A thin walled seal is disposed between the housing parts. When the housing parts are secured together by bolts, an outer periphery of the seal is compressibly sandwiched between the flat radial surface on the sealing ring and the flat surface on the second housing part thus sealing the window to the housing.

    Abstract: There is a gap between the respective inner regions of the end face of the cylindrical side wall and the abutting portion of the top plate, which are situated inside the seal member. Even though the top plate is bent inward by atmospheric pressure when the container is decompressed to a predetermined degree of vacuum, therefore, the abutting portion thereof cannot come into contact with the inner edge of the end face of the cylindrical side wall. Thus, if decompression and exposure to atmospheric pressure are repeated to bend the cylindrical side wall repeatedly, there is no possibility of the inner edge portion of the end face of the cylindrical side wall being separated or rubbed off to produce dust. Moreover, the cylindrical side wall and top plate are joined together in the region outside the seal member. If dust is produced by the contact between the cylindrical side wall and top plate at their junctions outside the seal member, therefore, it is prevented from entering the container by the seal member. Thus, a clean atmosphere in the container cannot be contaminated by the dust.

    Abstract translation: 在圆筒形侧壁的端面的各个内部区域和位于密封构件内部的顶板的抵接部分之间存在间隙。 因此，即使当容器减压到预定的真空度时顶板向内弯曲，因此其抵接部分不能与圆筒形侧壁的端面的内边缘接触。 因此，如果重复减压和暴露于大气压力以反复地弯曲圆筒形侧壁，则不会使圆柱形侧壁的端面的内边缘部分分离或摩擦而产生灰尘。 此外，圆筒形侧壁和顶板在密封构件外部的区域中接合在一起。 因此，如果在密封部件外侧的接合处产生圆筒形侧壁和顶板之间的灰尘，则可防止密封件进入容器。 因此，容器中的清洁气氛不会被灰尘污染。

    Abstract: A light-weight super high vacuum vessel is disclosed in which a super high vacuum pressure over 10.sup.-10 Torr or over 10.sup.-11 Torr can be achieved using a simple evacuation system and/or with a sealing structure. The super high vacuum vessel contains a member comprising: from 0.02 wt. % to 1.00 wt. % of at least one platinum-group metal selected from the group consisting of Pd, Pt, Rh, Ru, Re, and Os; from 0.1 wt. % to 3.0 wt. % of at least one transition metal selected from the group consisting of Co, Fe, Cr, Ni, Mn, and Cu; from 0.02 wt. % to 0.50 wt. % of at least one rare earth series element selected from the group consisting of La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, and Y; impurity elements of C, N, and O, C being equal to or less than 0.05 wt. %, N being equal to or less than 0.05 wt. %, O being equal to or less than 0.08 wt. %; and Ti and inevitable impurities.
