    • The present invention has an object to improve the flow property so as to increase the gas flow amount, to inhibit the gas from staying within a valve chamber, and to enhance the gas-replacement property such as evacuation performance and purge performance.A housing (2) is provided with a first flow passage (7), a valve chamber (9) of a shut-off valve (8) and a second flow passage (10) in the mentioned order. A diaphragm (13) is arranged so that it hermetically covers the valve chamber (9). The first flow passage (7) has an inner end opened into an inner surface of the valve chamber (9) to which a mid portion of the diaphragm (13) is opposed. A valve seat (15) is formed around this opening. The shut-off valve (8) is opened and closed by allowing the diaphragm (13) to approach and separate from the valve seat (15). A groove portion (18) is formed in the inner surface of the valve chamber (9) around the valve seat (15). A groove outlet/inlet (19) which communicates with the second flow passage (10) is opened into the groove portion (18) in an area larger than a circle having a diameter of a groove width (w). The second flow passage (10) communicates with the valve chamber (9) through the groove outlet/inlet (19) and the groove portion (18) in the mentioned order.
    • 本发明的目的是提高流动性,从而增加气体流量,抑制气体停留在阀室内,并且提高气体置换性能,例如抽空性能和吹扫性能。 壳体(2)按照上述顺序设置有第一流路(7),截止阀(8)的阀室(9)和第二流路(10)。 隔膜(13)被布置成使其气密地覆盖阀室(9)。 第一流路(7)的内端开放到阀室(9)的内表面,隔膜(13)的中间部分与其相对。 在该开口周围形成有阀座(15)。 关闭阀(8)通过允许隔膜(13)接近并与阀座(15)分离来打开和关闭。 在阀室(9)的内表面上形成有围绕阀座(15)的槽部(18)。 与第二流路(10)连通的沟槽出口/入口(19)在大于沟槽宽度(w)的直径的圆的区域内开放到槽部(18)中。 第二流路(10)以上述顺序通过槽出口/入口(19)和槽部(18)与阀室(9)连通。

    • A housing (2) has an upper portion engaged with a cylindrical stopper member (20) in screw-thread fitting so as to be able to vertically advance and retract the stopper member (20). The stopper member (20) has an outer thread (20a) engaged with a nut member (21) and has an inner thread (20b) engaged with a thrust screw member (23) each in screw-thread fitting. The stopper member (20) has a stopping portion (A) which prevents the downward movement of the intermediate transmission member (25) connected to the thrust screw member (23) over a predetermined distance. This inhibits a metal diaphragm (12) from being excessively pushed to a valve seat (15). When further moving the diaphragm (12) for valve closing, the nut member (21) is loosened and at the same time the stopper member (20) is advanced downwards to thereby define a gap between a receiving portion (B) of the intermediate transmission member (25) and the stopping portion (A).
    • 壳体(2)具有与螺纹配合的圆柱形止动构件(20)接合的上部,以能够使止动构件(20)垂直前进和后退。 止动构件(20)具有与螺母构件(21)接合的外螺纹(20a),并且具有与推力螺纹构件(23)接合的内螺纹(20b),每个螺纹配件都是螺纹配件。 止动构件(20)具有止动部(A),其阻止与止推螺纹构件(23)连接的中间传动构件(25)向下移动预定距离。 这阻止了金属隔膜(12)被过度地推到阀座(15)上。 当进一步移动用于阀关闭的隔膜(12)时,螺母构件(21)松动,同时止动构件(20)向下推进,从而在中间传动件的接收部分(B)之间限定间隙 (25)和止动部(A)。

    • The detection of rare cells can be achieved with high efficiency, without deteriorating the sensitivity of the detection. A detection method which enables the above-mentioned detection comprises: a first step of carrying out a pretreatment for removing erythrocytes from blood to prepare a cell suspension containing leukocytes and rare cells; a second step of providing all of the cells contained in the cell suspension produced in the first step onto an observation area having multiple holes formed thereon; a third step of taking an optical image of the cells that have been provided on the observation area; and a forth step of detecting the rare cells from the image obtained by the image taking in the third step.
    • 可以高效率地实现稀有细胞的检测,而不会降低检测的灵敏度。 能够进行上述检测的检测方法包括:进行从血液中除去红细胞的预处理以制备含有白细胞和稀有细胞的细胞悬液的第一步骤; 将包含在第一步骤中产生的细胞悬浮液中的所有细胞提供到其上形成有多个孔的观察区域的第二步骤; 第三步骤,获取已经设置在观察区域上的细胞的光学图像; 以及第三步骤,通过第三步骤中的图像拍摄获得的图像来检测稀有细胞。
