Abstract: A gate valve includes a body 12 having a valve member or gate chamber 18, passages 14, 16 communicating through the body into the chamber, a recess 38,40 in the body surrounding the opening of each passage into th chamber, a bushing 36 positioned in each of the recesses, a gate 20 positioned within the chamber, means for moving the gate within the chamber between positions communicating flow between the passages and closing flow between the passages, inner and outer undirectional seals 46,48 positioned between the surface of each of the recesses facing the gate and the opposing surface of the bushing in the recess. Each of the seals includes a U-shaped lip sealing element 50 and a U-shaped spring 56 positioned within the lip sealing element and urging the legs of the element apart into sealing engagement between the bushing and the body. The inner seal 46, which is positioned closest to the passage has the open end of its sealing element facing the passage and the outer seal 48, which is farther from the passage than the inner seal, has the open end of its sealing facing away from the passage. Each of the seals 46,48 is positioned within a recess in one of the bushings 36 and the body which has a depth less than the height of the seal while it is still in an effective sealing condition. The seals are compressible in height so that their bushings engage the body recess in a metal-to-metal seal when they are loaded and are recoverable from such compressed position to provide a tight seal when said loading is relieved. It is preferred that the seals utilize an aromatic polymer such as polytheretherketone or polyethersulfone for the lip sealing elements and an Eligiloy or nonferrous metal spring material for the spring.

Abstract: PURPOSE:To execute the operation at a high speed like a software by setting a logic threshold to a specific input signal which becomes a critical path of a cache memory in a form adapted to a substance of an input waveform of the cache memory. CONSTITUTION:By receiving an input signal for determining an operation speed by using an input circuit having a logic threshold voltage deviated to a negative level side, or by providing a level shift means on an output circuit in the semiconductor integrated circuit device of the other party for forming the input signal, a negative level of an output signal is deviated to the logic threshold voltage side of the input circuit for receiving it. Accordingly, by a relative level deviation to a negative level of the logic threshold voltage, an overhead 7 at the time when the input signal is varied from the negative level to an active level can be set to the minimum. In such a way, even if an element characteristic remains as it is, the operation can be executed at a high speed.
