Abstract: In a sensor element for a limiting-current type gas sensor measuring concentration of NOx in a measurement gas, an inner pump electrode located to face a first internal space communicating with a gas inlet through which the measurement gas is introduced from an external space under predetermined diffusion resistance is made of a cermet of a Pt—Au alloy and zirconia, and the inner pump electrode is located, from among surfaces defining the first internal space, at least on a surface farthest from a heater part in a thickness direction of the element, and is not located on a surface closest to the heater part in the thickness direction.

Abstract: An air-conditioning register includes a rotation direction changing mechanism, which changes the rotation direction of an operation knob and transmits the rotation to a shut-off damper to tilt the shut-off damper about damper pivots. The rotation direction changing mechanism includes arm portions and a cam member. Each arm portion includes a sliding end portion at the distal end, which moves along an arcuate passage having a center that coincides with the damper pivots in accordance with the tilting motion. A cam groove of the cam member includes sliding regions, along which the sliding end portions slide when the shut-off damper is tilted. Each sliding region includes free running regions on its opposite ends. The moving amount of the sliding end portions along the arcuate passage in the free running regions is less than that in an intermediate region when the cam member is rotated by a certain angle.

Abstract: An air conditioning round register includes a cylindrical retainer, an annular outlet ring supported so as to be able to be rotated in any direction, an opening and closing fin body supported so as to be able to be tilted, a control rotated with fingers, and a mechanism that converts rotation of the control into tilt of the fin body. The control includes a branch connection part placed on a central axis of the outlet ring, and three branches radially extending from the branch connection part and disposed at regular angular intervals around the central axis. At the branch connection part, a front end of each crotch surface portion between adjacent branches has a radius of 10 to 30 mm in front view. The front end of each crotch surface portion protrudes farther forward than a front end of the retainer by 8 to 15 mm.
