    摘要: A reactor comprising a body made of a heat-resistant material and having an inlet and an outlet for water/moisture gas, having a gas-diffusing member provided in an internal space of the body, and having a platinum coating on an internal wall surface of the body. Hydrogen and oxygen fed from the inlet are diffused by the gas-diffusing member and then come into contact with the platinum coating to enhance reactivity, thereby producing water. A temperature of the reactor is held to be below an ignition temperature of hydrogen or a hydrogen-containing gas. The platinum-coated catalyst layer on the internal wall of the reactor body is formed by treating the surface of the internal wall of the body, cleaning the treated surface, forming a barrier coating of a nonmetallic material of an oxide or nitride on the wall surface, and forming the platinum coating on the barrier coating.

    摘要: The present invention provides a vacuum thermal insulating valve that may be used at high temperature in gas supply systems or gas exhaust systems, and also may be made substantially small and compact in size owing to its excellent thermal insulating performance. With a vacuum thermal insulating valve comprising a valve equipped with a valve body and an actuator, and a vacuum thermal insulating box that houses the valve, the afore-mentioned vacuum thermal insulating box S is formed by a square-shaped lower vacuum jacket S5 having a cylinder-shaped vacuum thermal insulating pipe receiving part J on a side and with its upper face made open, and the square-shaped upper vacuum jackets S4, which is hermetically fitted to the lower vacuum jacket S5 and with its lower face made open.

    摘要: A fluid feeding apparatus includes parallel flow passages connected at their downstream side, each parallel passage including a pressure flow controller (C) for regulating the flow of fluid and a fluid changeover valve (D) for opening and closing the passage on the downstream side of the pressure flow controller. A fluid feeding control unit (B) controls the pressure flow controllers and changeover valves so that when a changeover valve is closed a control valve (1) upstream of the changeover valve is also closed to prevent a pressure buildup at the changeover valve. In addition to the control valve (1), each pressure flow controller includes an orifice (5) downstream from the control valve, a pressure detector (3) for sensing pressure (P1) in the passage at a point between the control valve and the orifice, and a calculation control unit (6) for producing a control signal Qy for controlling the drive (2) for the control valve. The calculation control unit first calculates a flow rate signal Qc=KP1, where K is a constant and P1 is the pressure sensed by the pressure detector. The calculation control unit then calculates Qy as the difference between a set point or flow rate specifying signal Qs and the calculated value Qc. Thus, the flow rate on the downstream side of the orifice is controlled by regulating the pressure P1 on the upstream side of the orifice via the control valve. The fluid feeding apparatus avoids transient overshooting at the start of fluid feeding and at fluid changeover time and is suitable for use in semiconductor manufacturing facilities and other gas supply systems where high precision is required.
