摘要:
A barrier film which has uniform thickness and excellent adhesiveness to the base material and superbly functions to protect a platinum film can be formed on the inner wall surface of a moisture-generating reactor at ease and at a low cost. The moisture-generating reactor in which hydrogen and oxygen are reacted to generate moisture without high temperature combustion is made of an alloy containing aluminum. A principally aluminum oxide (Al2O3)-composed barrier film is formed by applying an aluminum selective oxidation treatment on the inner wall surface of the moisture-generating reactor, and thereafter a platinum film is stacked on and stuck to the barrier film so that a platinum coating catalyst layer is formed.

摘要:
A safe, reduced pressure apparatus for generating water vapor from hydrogen and oxygen and feeding high purity moisture to processes such as semiconductor production. The apparatus eliminates the possibility of the gas igniting by maintaining the internal pressure of the catalytic reactor for generating moisture at a high level while supplying moisture gas from the reactor under reduced pressure. A heat dissipation reactor improvement substantially increases moisture generation without being an enlargement in size by efficient cooling of the reactor alumite-treated fins.

Disclosed is a method of controlling the flow rate of clustering fluid using a pressure type flow rate control device in which the flow rate Q of gas passing through an orifice is computed as K=KP1 (where K is a constant) with the gas being in a state where the ratio P2/P1 between the gas pressure P1 on the upstream side of the orifice and the gas pressure P2 on the downstream side of the orifice is held at a value not higher than the critical pressure ratio of the gas wherein the association of molecules is dissociated either by heating the pressure type flow rate control device to the temperature higher than 40° C., or by applying the diluting gas to the clustering fluid to make it lower than a partial pressure so the clustering fluid is permitted to pass through the orifice in a monomolecular state.

A reactor for generating moisture wherein ignition of hydrogen gas, backfire to the gas supply source side, the peeling off of the platinum coat catalyst layer inside are prevented more completely to further increase the safety of the reactor for generating moisture and wherein the dead space in the interior space is reduced to further reduce the size of the reactor shell. The reactor comprises: a reactor shell A with an interior space formed with a reactor structural component on the inlet side and a reactor structural component on the outlet side opposed to and united with each other by welding, the reactor structural component 1 on the inlet side provided with a gas feed port 1a and the reactor structural component 2 on the outlet side provided with a moisture gas take-out port 2a; a reflector on the inlet side facing the gas feed port in the interior space of the reactor; a reflector on the outlet side facing the moisture gas take-out port in the interior space; and a platinum coat catalyst layer 8 formed on the inside wall of the reactor structural component on the outlet side, wherein hydrogen and oxygen fed into the interior space of the reactor through the gas feed port are brought into contact with the platinum coat 8b to activate the reactivity, thereby reacting hydrogen and oxygen into water in a non-combustion state.

摘要:
A good quality passive-state film is formed on a gas-contact face of a diaphragm of a pressure detector using a sensor chip to prevent corrosion on, or water content emission from, or catalytic action at a gas-contact face, thereby improving production quality in a semiconductor manufacturing process and providing high accuracy pressure detection. The passive-state film is formed on the gas-contact face of the diaphragm when the diaphragm is mounted on a diaphragm base. The diaphragm base is then fixedly secured to a sensor base in which a sensor chip is housed and a pressure transmitting medium is sealed in a gap between the sensor base and the diaphragm base.
