Abstract: An intake sensor includes a detection element, a heater, a housing, and a protector. The protector has two or more tubular portions spaced from one another in the radial direction. Of any two adjacent tubular portions, a second tubular portion on the outer side has tubular walls present in the penetration direction of first through holes of a first tubular portion on the inner side. Second through holes of the second tubular portion have an area equal to or greater than that of the first through hole. When the intake sensor is disposed in a model gas mixture of butane and air having air-fuel ratio of about 13, pressure of about 0.11 MPa, temperature of about 20° C., and flow rate of about 0 m/sec, and the heater heats the solid electrolyte member to the target temperature, no combustion flame is visually recognized on the outer surface of the protector.

Abstract: A planar fuel cell apparatus (1) characterized in that, as viewed in a stacking direction, a first rectilinear line which connects a centroid Cfi of fuel gas inlets and a centroid Cfo of fuel gas outlets, and a second rectilinear line which connects a centroid Cai of oxidizer gas inlets and a centroid Cao of oxidizer gas outlets cross each other. That is, the planar fuel cell apparatus employs cross-flow design in which a fuel gas flow channel and an oxidizer gas flow channel cross each other. In the planar fuel cell apparatus of the cross-flow design, as viewed in the stacking direction, the centroid Cfo of the fuel gas outlets is located closer to the centroid Cai of the oxidizer gas inlets than to the centroid Cao of the oxidizer gas outlets.

Abstract: A spark plug where a predetermined cross section of a noble metal tip is divided by a vertical line into two half cross sections having a first half cross section and a second half cross section. The first half cross section satisfies h1/t≦0.2 and Rw1/Rt1≧1.03, and the second half cross section satisfies h2/t≦0.2 and Rw2/Rt2≧1.03. At a welding interface, an oxidation scale progresses in a direction away from an axis along side surfaces and changes the progressing direction at the end points so as to progress in a direction toward the axis along bottom surfaces. The progress of the oxidation scale is restrained. Since the noble metal tip is held by an engagement portion of a ground electrode, separation of the noble metal tip from the ground electrode 40 can be restrained.

Abstract translation: 一种火花塞，其中贵金属电极头的预定横截面被垂直线划分为具有第一半截面和第二半截面的两个半截面。 前半部分满足h1/t@0.2和Rw1 / Rt1> = 1.03，第二半截面满足h2/t@0.2和Rw2 / Rt2> = 1.03。 在焊接界面处，氧化刻度沿着沿着侧面的轴线的方向前进，并且在端点处改变前进方向，以沿着沿着底面的轴线方向前进。 氧化垢的进展受到限制。 由于贵金属端头被接地电极的接合部分保持，所以可以抑制贵金属电极头与接地电极40的分离。
