  • Publication number: 20190360887
    Abstract: A fluid controller is provided having a flow path through which a fluid can flow, a closed space separated from the flow path by an isolation member, and a leak port capable of communicating the closed space with an external part. An anomaly detection device for detecting an anomalty has a pressure sensor detachably fixed to the leak port, a pressure sensor for detecting the pressure in the closed space, a processing module for executing a predetermined information processing, and an detachable mechanism for blocking the leak port from the external part in the state of being fixed. The processing module determines an anomaly of the fluid controller by comparing a detection value detected by the pressure sensor to a predetermined threshold, and transmits a discrimination result of the anomaly of the fluid controller to a server.

  • Patent number: 7553459
    Abstract: 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.

  • Patent number: 6622543
    Abstract: A gas detection sensor permits precise measurement of the concentration of flammable gas in a detection or subject gas and the concentration of oxygen in a detection gas containing flammable gases. In the sensor, the heating of the sensor by contact catalytic reaction of flammable gas gives off a detection signal of the flammable gas. The gas detection sensor has a first detection sensor including a diaphragm having a platinum coat on a side which the flowing detection gas comes in contact with, and a thermocouple having respective ends of two different metals placed close to each other and fixed on the side of the diaphragm not coming in contact with the flowing detection gas and which is heated by the contact catalytic reaction of flammable gas. A second detection sensor similar to the first detection sensor detects the temperature of the flowing detection gas.

  • Patent number: 6387158
    Abstract: A method of removing moisture efficiently in the gas supply system by evacuation at normal temperature without using the baking method. The method involves flowing a gas to remove moisture in the gas supply system with the flow pressure of the gas to remove moisture set at not lower than a minimum pressure at which the gas flow becomes viscous and not higher than a water saturated vapor pressure at a flow temperature of the gas to remove moisture. The gas to remove moisture achieves a viscous flow when a mean free path of gas molecules is smaller than a diameter of piping of the gas supply system. If the gas for removing moisture is evacuated at normal temperature under such conditions, the adsorbed moisture on an inside surface of the piping and in the valves and filters can be removed effectively.
