Abstract: A metal oxide semiconductor gas sensor includes a first electrode, a second electrode, and a sensing layer in contact with the first electrode and the second electrode. The sensing layer includes SnO2 and WO3. A cross section of the sensing layer has an average porosity of 16.0% or more and 22.0% or less. SnO2 occupies 60 vol % or more and 80 vol % or less and WO3 occupies 20 vol % or more and 40 vol % or less in the sensing layer provided that pores are not counted as part of the sensing layer.

Abstract: In a steering apparatus, an upper bracket that supports a steering column is configured as a breakaway bracket, and has a telescopic adjustment function that allows the steering wheel position to be adjusted in the axial direction of the steering column. The upper bracket has a first through-hole extending through the upper bracket in the axial direction. The upper bracket is provided with a guide rail 7 that has a fixed portion and a body portion. The fixed portion is fixed to a mounting stay. The body portion extends from the fixed portion toward the front of a vehicle in the axial direction, and is inserted in the first through-hole.

Abstract: For an immersed pump having a suction port directly immersed in a liquid for operation, the present invention provides a pump that eliminates the need to seal a rotating shaft with a shaft sealing apparatus and that reduces the effect on individual pump sections of a) the thrust of the rotating shaft effected by the rotation of an impeller and b) the weight of a motor acting in the same direction, thereby preventing defects in the pump. To achieve this object, this invention provides an immersed pump configured in such a way that an impeller 7 is driven and rotated by a motor 2 to draw a liquid from a suction port 4A into a pump housing 3A and eject it from an ejection port 5. The suction port 4A is provided at the lower end of a body frame 1 or on the outer circumference of the upper end of the housing 3A, while the ejection port 5 is provided at the lower end of the housing 3A.
