Abstract: The present invention suppresses an adverse effect caused when an additional gas such as water vapor is mixed in a sample gas or the like that is subjected to gas measurement. In an embodiment of the present invention, in gas measurement for analyzing sensor output signals obtained by alternately supplying a sample gas and a reference gas to a sensor element while alternately switching between the sample gas and the reference gas, the sample gas and the reference gas pass through a humidity equilibration device partitioned by a water vapor permeable membrane, and then are supplied to the sensor element. As a result, since both gases have substantially the same value of humidity at the time of being supplied to the sensor element, influences of water vapor are substantially cancelled out in signals output from the sensor element by the alternate supply of the sample gas and the reference gas.

Abstract: Solid electrolytic capacitors and methods for manufacturing the solid electrolytic capacitor are provided. The solid electrolytic capacitor has excellent reliability by virtue of stress reduction inside an electrolyte layer, which alleviates decrease in capacitance, increase of ESR and leakage current, and suppression of short circuits. The anode of the solid electrolytic capacitor is formed of a valve metal or an alloy thereof as a porous body. Subsequently, a dielectric layer is formed on a surface inside the porous body of the anode, and the electrolyte layer is formed on a surface of the dielectric layer. Here, the electrolyte layer is formed of a conductive polymer and the electrolyte layer inside the porous body of the anode contains an elastomer. Thereafter, a cathode is formed so as to come in contact with the electrolyte layer.
