    摘要： A method and apparatus for detection of clogging of an orifice by measuring the upstream side pressure without breaking up the piping system in a flow rate control unit using an orifice, so as to extend the life of the flow rate control unit and enhance its safety. The apparatus of detecting clogging of an orifice in a pressure-type flow rate controller has a control valve (CV), an orifice (2), a pressure detector (14) for measuring the upstream pressure P1 therebetween, and a flow rate setting circuit (32) wherein, with the upstream pressure P1 maintained about two or more times higher than the downstream pressure P2, the downstream flow rate QC is calculated with the equation QC=KP1 (K=constant) and wherein the control valve (CV) is controlled by the difference signal QY between the calculated flow rate QC and the set flow rate QS. The apparatus comprises: a storage memory M memorizing standard pressure attenuation data Y(t) of the upstream pressure P1 measured with the flow rate switched from the high set flow rate QSH to the low set flow rate QSL with the orifice (2) not clogged, a pressure detector (14) for determination of the pressure attenuation data P(t) of the upstream pressure P1 with the flow rate switched from the high set flow rate QSH to the low set flow rate QSL with the orifice (2) in the actual conditions, a central processing unit CPU for checking the pressure attenuation data P(t) against standard pressure attenuation data Y(t), and an alarm circuit (46) that turns on a clogging alarm when the pressure attenuation data P(t) deviates from standard pressure attenuation data Y(t) to a specific degree or beyond that.

    摘要： An electron beam working apparatus for cylindrical workpieces having a circular working line is improved so that a volume of a vacuum chamber to be maintained can be minimized and the vacuum chamber may not contain a contamination source such as a driving motor. In order to achieve the improvements, two disk-shaped partition plates having inflatable annular seal members disposed along their respective outer peripheral surfaces are placed inside the cylindrical workpieces respectively above and below the working line with said seal members pressed against the inner peripheral surfaces of said cylindrical workpieces to form a first vacuum chamber surrounded by said two partition plates and the inner peripheral surfaces of said cylindrical workpieces. Two annular fixed chamber wall members having inflatable annular seal members disposed along their respective inner peripheral surfaces are placed outside the cylindrical workpieces respectively above and below said working line with said seal members pressed against the outer peripheral surface of said cylindrical workpieces and an annular rotary chamber wall member provided with an electron beam gun is rotatably provided around the two annular fixed chamber wall members so that the inner peripheral surface of the former may make slide contact with the outer peripheral surfaces of the latter via seal members to thereby form a second vacuum chamber surrounded by the outer peripheral surfaces of said cylindrical workpieces, said two annular fixed chamber wall members and the inner peripheral surface of said rotary chamber wall member.
