Abstract: Provided is a water faucet capable of ensuring a required strength even when an exterior of the water faucet is formed with a cross-sectional shape having a longer direction and a shorter direction in a cross-section. The water faucet (1) comprises: an exterior member (4) having a longer direction (L1) in a cross-section and a shorter direction (W1) in the cross-section, and forming an exterior of the water faucet (1); a discharging port (34) for discharging water therefrom; a water-conducting member (8) for providing fluid communication between the discharging port (34) and a water supply source for supplying water to the discharging port (34); and a reinforcement member (10) provided inside the exterior member (4) so as to reinforce the exterior member (4).

Abstract: A surge protective device of the present invention includes an insulating tube 2, a pair of sealing electrodes 3 for closing openings on both ends of the insulating tube so as to seal a discharge control gas inside the tube, wherein the pair of sealing electrodes has a pair of convex electrode portions 5 projecting inwardly so as to face to each other, and at least one projecting part 2a projecting inwardly in a radial direction and extending in a circumferential direction is formed on the inner circumferential surface of the insulating tube.

Abstract: To provide a discharge tube having improved stability of operating voltage to repeated discharges. The discharge tube includes a cylindrical insulating hollow body having openings at least at both ends and at least a pair of sealing electrodes facing to each other for closing the openings so as to seal a discharge control gas inside the body, wherein a discharge trigger film made of a conductive material is formed on the inner circumferential surface of the insulating hollow body, each of the sealing electrodes has a convex portion projecting into the insulating hollow body and a discharge active layer(s) that is/are made of a material having higher electron emission characteristics than that of the sealing electrodes.
