摘要： A manual control valve apparatus having a structure which is provided with, as a conversion mechanism, a diaphragm compressor which is held between a valve casing and a guide member, arcuate engaging grooves formed in a surface of the diaphragm presser opposite to the valve stem, and rolling elements which engage in a freely rolling manner in the engaging grooves and are supported by the lead end part of the valve stem. The bottom surfaces of the engaging grooves are made cam surfaces for causing reciprocating motion in the axial direction of the valve stem. An indicator possessing opening indicating portions indicating the rotational position of the valve stem is attached to the opposite end of the guide member from the valve casing, and furthermore, windows exposing the opening support portions are provided in an area from the circumferential wall of the handle to the end wall thereof. Using this structure, it is possible to compactly incorporate an indicator indicating a degree of valve opening around the handle. Furthermore, the structure of the conversion mechanism is simplified and can be miniaturized, so that it is possible to incorporate the conversion mechanism within the guide member.

摘要： A supply control apparatus for semiconductor process gasses which is capable of accurately switching the timing of the supply state of the gasses flowing in accordance with the open or closed states of a plurality of gas pressure operated valves, which operate in response to a plurality of electromagnetic valves operating in time series. The content volumes of a plurality of gas tubes respectively connecting the plurality of electromagnetic valves to the plurality of drive units of the gas pressure operated valves are determined as a function of the length of time elapsed between the application of the control signal and the time the special gas is supplied to a process unit. The apparatus permits accurate switching of the supply state of the special gasses and avoids the mixing of the semiconductor process gasses.

摘要： A method of measuring external leakage, which comprises the steps of introducing a first gas different from main component gasses of an external atmosphere into a pipe having a leak, adding H.sub.2 gas (or H.sub.2 -containing gas) to the first has at a down-stream point, and measuring gas components entering from the external atmosphere of the leak by an atmospheric ionization mass spectrometer (atmospheric pressure ionization mass spectrometer) at a further downstream point (for example, N.sub.2 H.sup.+ is detected when the external atmosphere is the N.sub.2 gas). A method of measuring the external leakage of a gas supply piping line having a plurality of branch piping lines comprises the steps of introducing H.sub.2 gas (or a H.sub.2 -containing gas) into at least one of the branch piping lines, introducing a first gas different from main component gases of an external atmosphere into the rest of the branch piping lines, and measuring gas components entering from the external atmosphere by the atmospheric pressure ionization mass spectrometer at a downstream point of the branch portion. The present invention can measure the external leakage very simply and with high levels of sensitivity and accuracy. Particularly, the present invention can be suitable applied to the cases where an inspection portion is elongated or branched such as feed pipe of a semiconductor plant.
