    摘要: A pressure type flow rate control apparatus (1) controls flow rate of a fluid in an environment where a ratio of P2/P1 between an absolute pressure P1 at an upstream side of an orifice and an absolute pressure P2 at a downstream side of the orifice is maintained at a value less than about 0.7. The apparatus comprises: a plate for forming the orifice (5); a control valve (2) positioned upstream of the orifice; an orifice corresponding valve (9) positioned downstream of the orifice (5); a primary pressure detector (3) positioned between the control valve (2) and the orifice (5); a secondary pressure detector (11) positioned downstream of the orifice (5); a calculation control device (6) for calculating flow rate Qc on the basis of the measured pressure P1 of the primary pressure detector (3) by a formula Qc = KP1 (K being a constant) and for outputting as a control signal Qy a difference between a flow rate command signal Qs and the calculated flow rate signal Qc to a drive unit (14) of the control valve 2; and a pressure comparing, calculating apparatus (10) for calculating the ratio of P2/P1 between the detected pressure P1 of the primary pressure detector (3) and the detected pressure P2 of the secondary pressure detector (11). The pressure P1 upstream of the orifice is adjusted by opening and closing the control valve by the control signal Qy, thereby controlling the flow rate downstream of the orifice.

    摘要: An improved reactor for generating water from hydrogen and oxygen which allows production of moisture at a high reaction rate exceeding 99 percent with the temperature kept under some 400°C inside the reactor shell (1) and with the moisture production being more than 1, 000 sccm. One form of the reactor (Fig. 1) according to the invention is made up with two bottomed cylinders, a first reactor structural component (2) and a second reactor structural component (3), united to define a sealed interior space (1a). The sealed interior space (1a) of the reactor shell (1) is partitioned by adiffusion filter (10) into a first chamber (1b) provided with an inlet reflector unit (9) and a second chamber (1c) provided with an outlet reflector-diffuser unit (11). On the inside surface of the second reactor structural component (1c) is formed a platinum coated catalyst layer (13). The inlet reflector unit (9) comprises a cylindrical casing (9a) mounted over a material gas feed port (2c) on the inside surface of the first reactor structural component (2), side openings (9c) formed in the casing (9a) and a reflector (9b) closing the open end of the casing (9a). The outlet reflector-diffuser unit (11) has a cylindrical casing (11a) fixed over a moisture gas outlet port (3c) on the inside surface of the secondreactor structural component (3), side openings (11e) formed in the casing, a reflector (11b) closing the open end of the casing (11a), an outlet diffusion filter (11c) provided inside the casing (11a) and a platinum coated catalyst layer (11d) formed on the outlet diffusion filter (11c).

    摘要: A fluid control system, and its valve assemblies, are used to control the feeding of fluids accurately (by operating (opening and closing) valves promptly and accurately), for the manufacture of semiconductors, magnetic thin films, biotechnical products, and other products. The fluid control system comprises a principal control line (L) and plural branch control lines (L 1 , L 2 , ...) for feeding plural types of fluid (G 1 , G 2 ,...) into a processing device (C) coupled to the principal control line, and plural valve assemblies (V) incorporated in the branch control lines (L 1 , L 2 ,...) for switching the fluids (G 1 , G 2 ,...) supplied into the processing device (C). Each of the valve assemblies (V) comprises a fluid drive valve (V') having a fluid pressure actuator (1), and an electromagnetic valve (V") integrally attached, in single housing, substantially without hoses, to the fluid drive valve (V') to feed a working fluid (A) into the fluid pressure actuator (1).
