摘要： A regulator for regulating a flow rate is provided with an upper connector having a downwardly opened channel in communication with the regulator. An on-off valve connected to the regulator is provided with a lower connector having an upwardly opened channel in communication with the on-off valve. The upper connector is lapped over the lower connector and removably joined thereto with a screw so as to cause the downwardly opened channel to communicate with the upwardly opened channel. Accordingly, the regulator can be removed singly, for example, when malfunctioning.

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.degree.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 a diffusion 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 second reactor 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 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： A valve body has a main body formed with an inflow channel for a first fluid, an inflow channel for a second fluid, and an outflow channel for the first and second fluids in common. The first fluid inflow channel is always in communication with the common outflow channel through a valve chamber. A valve element operates to bring the second fluid inflow channel into or out of communication with the first fluid inflow channel and the common outflow channel.

摘要： A pipe joint comprises a pair of tubular joint members having a gasket holding annular projection on each of butting faces thereof, an annular gasket interposed between the butting end faces of the joint members, and a nut for connecting the joint members together. When the nut is tightened up, an indentation is formed in a surface of the gasket pressed by each of the gasket holding projections, and the gasket is pressed also by a portion of the end face of each joint member having no annular projection.

摘要： A pair of tubular joint members each have a gasket holding annular protuberance on an abutting end face thereof. The protuberance has an inner peripheral surface continuous with the inner peripheral surface of the joint member, and a sealing face adapted to intimately contact an end face of of a gasket at a position radially outward from the inner peripheral surface thereof. The sealing face is most protuberant at a position radially outward from an inner edge thereof. When the most protuberant end of the sealing face comes into contact with the gasket end face, a clearance is formed between the portion of the sealing face radially inward from the protuberant end and the radially inward portion of the gasket end face. The clearance is eliminated by the deformation of the gasket when the pipe joint is tightened up.

摘要： The object of the present invention is to form a chromium-oxide film excellent in corrosion resistance without containing an oxide film of other metal onto the optional metallic material. The chromium-oxide passivation film excellent in corrosion resistance without containing the oxide film of other metal can be formed inexpensively and in a short time, and a fluid supplying system for supplying fluid hard in corrosivity in safety is able to be provided. This invention comprises a step of forming the passivation film consisting of a chromium oxide by giving heat treatment in an oxidizing atmosphere after coating chromium on metallic material of which surface roughness (Ra) of a coat surface is not more than 1.5 mu m.
