Abstract: A highly accurate and relatively inexpensive control valve for a compressor. The control valve includes a pressure sensitive portion that has a metal diaphragm, which is machined with a relatively low cost. The diaphragm is held between flanges. The pressure sensitive portion is attached to a control valve portion after being subjected to a pressure leak test. The control valve portion has an engaging piece and a positioning surface. The flange contacts the positioning surface and is fixed by the engaging piece. The positioning surface is formed such that the interval between the diaphragm and the top of the valve chamber becomes a predetermined value.

Abstract: There is disclosed a semiconductor processing apparatus comprising a process chamber treating a substrate, a process gas feeder feeding a process gas to the process chamber, a first vacuum pump exhausting the process chamber, a second vacuum pump inhaling gas on an exhaust side of the first vacuum pump, and a circulation path circulating at least a part of the process gas exhausted from the process chamber via the first vacuum pump into the process chamber, wherein the circulation path is provided with a dust trapping mechanism, the dust trapping mechanism being capable of substantially maintaining a conductance of the circulation path before and after the capture of dust.

Abstract: Etching selectivity is improved in a semiconductor process using a fluorocarbon gas. An energy incident to a substrate is controlled to have a value to cause transition from etching to deposition on a silicon nitride film, ions having (CF.sub.2).sub.n.sup.+ as a major component are guided onto the substrate to perform selective etching of a silicon oxide film against the silicon nitride film.

Abstract: A control system for an automatic transmission includes a shift gear mechanism for shifting respective shift gear stages, a shift line map including upshift lines and downshift lines, and a device for detecting a shift timing at which an shift operation should be carried out based on an engine load on the shift line map and a possibility is estimated that a driving condition will return back to the previous shift gear stage. The system also includes an engine load detecting device for detecting a stable condition of the engine load, and a controller for controlling the shift gear mechanism based on the shift line map after the engine load detecting device detects the stable condition of the engine load at the shift timing detected by the shift timing detecting device.
