Abstract: Provided is an exhalation sensor that utilizes heat effectively and can operate with low power consumption. The exhalation sensor has a surface layer on its surface that faces a sensor main body, and the performance of the surface layer to reflect radiant heat is higher than that of a housing. Specifically the radiant heat reflectivity of the surface layer is higher than that of the housing. Therefore, the surface layer can reflect radiant heat emitted from the sensor main body more efficiently than the housing. The radiant heat emitted from the sensor main body is less likely to escape to the outside of the housing, so that the heat generated by a heater of the sensor main body can be efficiently stored within the housing. This can reduce the power consumed by the heater to heat a conversion section and a sensing section to their operating temperatures.

Abstract: Disclosed is a gas sensor including: a wiring board; a sensor element mounted on the wiring board and electrically connected to the wiring board by conductive members; a casing installing the sensor element and formed with inlet and outlet ports; and a pretreatment unit configured to perform pretreatment on a measurement gas and feed the measurement gas to the inlet port. The inlet and outlet ports are located outward and upward of the sensor element. A protrusion is provided protruding toward the inside of the casing so as to narrow a flow path from the inlet port to the outlet port. A height from the sensor element to a distal end of the protrusion is lower than heights from the sensor element to the inlet and outlet ports. The protrusion is disposed more inside than respective top portions of the conductive members without being in contact with the conductive members.

Abstract: A gas sensor includes an adjustment unit having a concentration adjuster which changes the concentration of a particular gas component contained in measured gas introduced into a first chamber, a sensor unit having a second chamber for receiving the measured gas which has passed through the adjustment unit and a detector whose electrical characteristic changes with the concentration of the particular gas component, a single heater for heating the concentration adjuster and the detector, and a gas flow tube having the form of a pipe, at least partially running externally of the adjustment unit and of the sensor unit, and adapted to establish communication between the first chamber and the second chamber. The adjustment unit, the sensor unit, and the heater are united together in such a manner as to establish thermal coupling between the adjustment unit and the heater and thermal coupling between the sensor unit and the heater.

Abstract: A gas sensor including an adjustment unit having a conversion element for converting a gas component contained in exhaled breath introduced into a first chamber to a particular component, a sensor unit having a second chamber and including a detection element, a ceramic wiring board electrically connected to the detection element, and a single heater for heating the conversion element and the detection element. The ceramic wiring board has an opening, and a ceramic thin plate is stacked on the ceramic wiring board to cover the opening. The ceramic thin plate partially constitutes the adjustment unit and the sensor unit and separates the first chamber and the second chamber from each other. The adjustment unit, the sensor unit, and the heater are integrated in such a manner that the adjustment unit and the sensor unit are thermally coupled through the ceramic thin plate.

Abstract: A breath sensor (1) includes a heat exchange portion (41) that allows heat exchange between breath discharged from a second chamber C2 and breath introduced into a first chamber C1. Therefore, breath introduced into the first chamber C1 can be heated by breath discharged from the second chamber C2, to increase the temperature of the introduced breath. Since the temperature of the breath is increased, an effect of reducing power consumption of a heater (29c) in heating a conversion portion (21) and a detection portion (29a) is realized. The heater (29c) heats both the conversion portion (21) and the detection portion (29a) to a temperature in an operation or activation temperature range. Further, power consumption for heating to an operation temperature can be reduced by preheating the introduced breath as described above.

Abstract: The present invention is for providing an oil-impregnant sintered bearing, which can reliably preserve an oil film on a sliding face, and a method for manufacturing the oil-impregnant sintered bearing. An oil-impregnant sintered bearing is made by providing an internal diameter, which a rotating axis member is inserted through, in a bearing main body, formed by a porous sintered alloy having internal pores therein, and providing a sliding face in one region of the inner peripheral face of the internal diameter, the sliding face being obtained by closing the pores which have been opened in the inner peripheral face. The density in a section preserving oil pressure, which extends from the sliding face of the bearing main body toward the outer side of the diameter, is made higher than the density in other sections of the bearing main body.
