Closing device for a gas-conducting line, the closing device having a first connection side with a first opening and a second connection side with a second opening, the closing device further having a plurality of closing elements with a substantially flat extension, which are arranged in and can be pivoted in a working plane, so that the closing elements block a flow of gas in a closed position and allow a free flow of gas in a flow position, wherein each closing member has a first bounding side of its substantially flat extent and a second bounding side of its substantially flat extent, which are formed complementary to each other, so that each closing element bears positively against the adjacent closing elements in the closed position, so that the substantially flat extensions block the flow, and wherein the adjusting element can be actuated from outside the base body.

The present application discloses a vacuum pumping valve for semiconductor equipment and a vacuum control system, wherein the vacuum pumping valve includes a driving device, a base, a rotary disk, and a set of blades, wherein the blades are mounted between the base and the rotary disk, the rotary disk driven by the driving device drives the blades to move synchronously on the base, the moving blades together form a pumping orifice, the shape of the pumping orifice is a regular polygon coaxial with the rotary disk, and the opening of the pumping orifice is adjustable by means of synchronous movement of the blades. In the present application, the effective passage area of the gas flow and vacuum pressure of the reaction chamber can be controlled, and the problem of an asymmetric gas plasma distribution can be effectively resolved.

A system for a packer in a well includes a completion string, having production tubing, disposed within the well. The packer is connected to the production tubing and the production tubing defines an annulus in the well. A full-bore iris isolation valve is installed on the production tubing and located downhole from the packer. The full-bore iris isolation valve has an open position, a closed position, and a plurality of blades. The closed position isolates the annulus from an inner orifice of the production tubing to set the packer in the well. An activation mechanism, disposed adjacent to and up hole from the full-bore iris isolation valve, is configured to interact with the plurality of blades to place the full-bore iris isolation valve in the open position and the closed position. A sliding sleeve, having an inner profile, is connected to and located up hole from the activation mechanism. A setting tool has an external circumferential surface that mates with the inner profile of the sliding sleeve to apply a push force and a pull force to the sliding sleeve. The push force is applied to the full-bore iris isolation, using the activation mechanism, to place the full-bore iris isolation valve in the closed position and the pull force is applied to the full-bore iris isolation, using the activation mechanism, to place the full-bore iris isolation valve in the open position.

The present invention includes a server system that uses an airflow source that can be external to the computer that the airflow source cools. The computer may be sealed such that the conduits are the primary source of fluid ingress and egress. The airflow source can be positioned in a case of the computer, support members affixing the computer to a rack stand, the rack stand, or beyond conduit that conducts fluid to the rack stand.

An airlock system that includes a plurality of adjacent chambers successively arranged along a guide path. Predetermined pressures are produced in each chamber so that the predetermined pressure in each chamber is at a pressure different from the predetermined pressure produced in an adjacent chamber. Gate valves are positioned to separate adjacent chambers in order to maintain a pressure differential between the adjacent chambers.
