Abstract: It is possible to reduce a decrease in accuracy of measuring the concentration of a measurement target gas even in a case where, in a mixture of gases, there is a gas greatly different from another gas in a rate of change in thermal conductivity with respect to temperature. The concentration measurement device includes a sensor configured to measure the concentration of a measurement target gas in a mixture of gases on the basis of thermal conductivity of the measurement target gas, the mixture of gases including two or more components, and a heating unit configured to heat the mixture of gases so that the concentration of the measurement target gas can be uniquely determined with respect to the thermal conductivity.

Abstract: A capacitive transducer includes a substrate having an opening in a surface thereof, a back plate facing the opening in the substrate, a vibration electrode film facing the back plate across a space, the vibration electrode film being deformable to have a deformation converted into a change in capacitance between the vibration electrode film and the back plate, the vibration electrode film having a through-hole as a pressure relief hole, and a protrusion integral with and formed from the same member as the back plate, the protrusion being placeable in the pressure relief hole before the vibration electrode film deforms. The protrusion and the pressure relief hole have a gap therebetween defining an airflow channel as a pressure relief channel.

Abstract: A capacitive transducer includes a substrate having an opening in a surface thereof, a back plate facing the opening in the substrate, a vibration electrode film facing the back plate across a space, the vibration electrode film being displaceable to have a displacement converted into a change in capacitance between the vibration electrode film and the back plate, an airflow channel defined by a gap between a protrusion integral with the back plate and a part of the vibration electrode film, the airflow channel being configured to increase an area of air flow when the vibration electrode film deforms under pressure to move relative to the protrusion integral with the back plate and relieve the pressure applied to the vibration electrode film to serve as a pressure relief channel, and an extension formed at a periphery of a hole in the vibration electrode film defining the pressure relief channel.

Abstract: A silicon substrate has a chamber that penetrates vertically. A diaphragm is formed on the upper surface of the silicon substrate so as to cover the upper portion of the chamber. Also, a back plate is provided above the silicon substrate so as to cover the diaphragm, and a fixed electrode plate is provided on the lower surface of the back plate in opposition to the diaphragm. Multiple acoustic holes, which penetrate vertically and are for allowing the passage of acoustic vibration, are formed in the back plate (28) and the fixed electrode plate. Multiple through-holes that have a smaller opening area than the acoustic holes are formed in a large displacement region of the diaphragm.
