    Abstract: Techniques for a door system for sealing an opening between two chambers in a semiconductor processing system are described. A sealing member seals the opening when a door is in a closed position. To selectively open and close the opening, an actuator moves the door. A valve actuator switch provides a first or second pressure to the actuator depending on the pressure inside a first chamber. In one embodiment, a sensor monitors the pressure inside the first chamber.

    Abstract: A hinge device prevents breakage of a structuring part from an increase in an internal pressure during overload. In the hinge device, first and second members are rotatable relative to each other. A case is fixed to either the first or second member, and a shaft body capable of rotating relative to the case is fixed to the other. A first chamber and a second chamber formed between the case and the shaft body are filled with viscous fluid. An orifice between the first and second chambers narrows a flow path for the viscous fluid moving from the first to second chamber, resisting rotation of the shaft body. A space region is provided in the shaft body, with a valve body movably placed therein. When pressure of the first chamber reaches a predetermined level, the valve body moves in the space region to increase the volume of the first chamber.

    Abstract: A locking device for selectively securing two movable objects in desired positions relative to each other includes a cylinder and a piston movable within the cylinder and defining first and second working chambers of variable volumes. A fluid exchange connection provided on the piston includes a flow chamber having openings that communicate with the working chambers. A valve body slidably received on the piston in sealed relation is biased by a spring into a position closing the opening from the flow chamber to first working chamber. When the fluid pressure in the second working chamber exceeds a predetermined amount and acts on the valve body, the valve body is moved against the spring bias and opens to allow fluid to flow through the fluid exchange connection. In the open position, a larger area of the valve body is exposed to the pressure in the second chamber. A restriction in the flow path between the flow chamber and the first chamber produces a pressure drop between the flow chamber and the first chamber and allows the fluid exchange connection to remain open with a reduced pressure in the second chamber. The device thus provides for a large holding force when the valve body closes the opening and a small resistance to movement after the valve body is moved from closed. By providing two spring-biassed valve bodies acting in opposed directions, control of movements of objects in opposite directions is obtained.

    Abstract translation: 用于将两个可移动物体相对于彼此选择性地固定在期望位置的锁定装置包括可在气缸内移动并限定可变体积的第一和第二工作室的气缸和活塞。 设置在活塞上的流体交换连接件包括具有与工作室连通的开口的流动室。 以密封的关系可滑动地容纳在活塞上的阀体被弹簧偏压到从流动室将开口关闭到第一工作室的位置。 当第二工作室中的流体压力超过预定量并作用于阀体时，阀体抵抗弹簧偏压运动并打开以允许流体流过流体交换连接。 在打开位置，阀体的较大面积暴露于第二室中的压力。 在流动室和第一室之间的流动路径中的限制在流动室和第一室之间产生压降，并允许流体交换连接在第二室中以减小的压力保持打开。 因此，当阀体关闭开口时，该装置提供大的夹持力，并且在阀体从关闭状态移动之后具有较小的阻力。 通过提供两个在相反方向上作用的弹簧偏压阀体，可以获得相反方向上物体运动的控制。
