    • A medical device and production method therefor which can retain antimicrobial activity for a prolonged period of time under physiological indwelling conditions and also having a physiologically active function. The production method is independent of the kind of base material selected for the medical device. The antimicrobial medical device having physiological activity comprises a cross-linked coating film constituting a high molecular weight substance having acid anhydride groups formed on a surface of a base material. The cross-linked coating film is formed by reacting preferably from 0.5 to 10 mol % of the acid anhydride groups contained in the high molecular weight substance with a compound having two or more active hydrogen atoms in one molecule. Also, a physiologically active substance and an antimicrobial substance are bonded to the cross-linked coating film.

    • A directional control valve for a penumatic cylinder in which a piston of the cylinder can be lowered and elevated in a high speed with a minimum air consumption and the lowering/rising speed of the piston can be controlled before it reaches the upper/lower end portions to prevent bounding of the piston. The directional control valve includes a first pressure chamber communicating with an air supply, a second pressure chamber communicating with one of cylinder chambers divided by the piston of the cylinder, an exhaust pressure port, a pressure controlling mechanism, a pressure controlling and changing means which forms a pressure controlling chamber and a pressure receiving chamber, a first valve member for communicating the first pressure chamber and the second pressure chamber, a second valve member for communicating the second pressure chamber and an atmospheric pressure chamber, a third valve member for communicating the second pressure chamber and a pressure-receiving member, and a fourth valve member which is communicating with the third valve member, the air supply and a pressure control chamber.
    • 一种用于气缸的方向控制阀,其中气缸的活塞可以以最小的空气消耗高速降低并且升高,并且可以在其到达上/下端部之前控制活塞的下降/上升速度 以防止活塞的界限。 方向控制阀包括与空气源连通的第一压力室,与由气缸的活塞分隔的气缸室中的一个连通的第二压力室,排气压力端口,压力控制机构,压力控制和变更装置, 形成压力控制室和受压室,用于连通第一压力室和第二压力室的第一阀构件,用于连通第二压力室和大气压力室的第二阀构件,用于使第二压力室和第二压力室连通的第三阀构件 第二压力室和压力接收构件,以及与第三阀构件,空气供应和压力控制室连通的第四阀构件。
