Abstract: A gas sensor (1) including: a sensor element (5) having an electrode pad (31, 32, 34, 35); a metallic terminal member (41) electrically connected to the electrode pad; and a lead wire (37) electrically connected to the metallic terminal member. The metallic terminal member has a forward-end-side terminal portion (43) which comes into contact with the electrode pad and a rear-end-side terminal portion (45) which is connected to the lead wire. The forward-end-side terminal portion has a bent portion (43d), and an element contact portion (43e) which comes into contact with the electrode pad. The rear-end-side terminal portion has a crimp terminal portion (45a) which forms a tube or a part of a tube, surrounds a conductor (37a) of the lead wire, and fixedly holds the conductor when crimped. Further, the maximum thickness t1 of the bent portion is greater than a maximum thickness t2 of the crimp terminal portion.

Abstract: A YAG sintered body has a predetermined surface where intragranular pores are exposed. On the predetermined surface, arithmetic average roughness Ra satisfies Ra≤0.5 μm, and a ratio between maximum height Rz and maximum valley depth Rv satisfies Rv/Rz≤0.7. With this configuration, the predetermined surface of a processed surface is smoothed to have improved plasma resistance and exhibit a particle-suppressing effect.

Abstract: An example of a nitric oxide (NO) releasing film includes a substrate; an NO donor film attached to the substrate; and an NO permeable and light transparent film positioned on the NO donor film. The NO donor film includes a polymer matrix selected from the group consisting of a non-UV curable polyurethane, polyvinyl butyral, polystyrene, copolymers of styrene, block copolymers of styrene, poly(ethersulfone), polyvinylpyrrolidone, polyvinyl acetate, poly(ethylene-co-vinylacetate), and combinations thereof; and solid, light sensitive NO donor particles distributed throughout the polymer matrix. The solid, light sensitive NO donor particles have a volume-weighted mean diameter of 50 μm or less. In one example, the NO donor film further includes an additive, such as NO2 scrubber particles, a radical stabilizer, dispersant, and/or an anti-skinning additive.
