摘要： A gas detection sensor capable of being simplified in structure and detecting, with high accuracy, the concentration of inflammable gas contained in a detected gas and the concentration of oxygen gas contained in the detected gas containing the inflammable gas under the presence of H2O or O2, comprising a first detection sensor which has a diaphragm with a platinum coated film applied on a gas contact surface in contact with the detected gas and a thermocouple which is obtained by moving for fixing one end side of each of two dissimilar metals closely to the non-gas contact surface of the diaphragm and is heated by the contact reaction of the inflammable gas and a second detection sensor which has a diaphragm with a gas contact surface in contact with the detected gas and a thermocouple obtained by moving for fixing one end side of each of two dissimilar metals closely to the non-gas contact surface of the diaphragm and detects the temperature of the detected gas, whereby the detection signals of the inflammable gas can be transmitted by the heating of the sensors due to contact reaction of the inflammable gas.

摘要： A fluid supply apparatus with a plurality of flow lines branching out from one pressure regulator with the flow lines arranged in parallel and constructed so that opening or closing one flow passage will have no transient effect on the steady flow of the other flow passages. Each flow passage is provided with a time delay-type mass flow controller MFC so that when one closed fluid passage is opened, the mass flow controller on that flow passage reaches a set flow rate Qs in a specific delay time DELTAt from the starting point.The invention includes a method and an apparatus in which a plurality of gas types can be controlled in flow rate with high precision by one pressure-type flow control system.
