    摘要: In a surface treatment apparatus (30) of the face type, a porous dielectric (37) is supported by the outer periphery portion of the supporting member (45) under the bottom surface of a porous electrode (32). The dielectric can be supported by the supporting member to permit the thermal expansion deformation of the dielectric by forming an upward inclined-face (47) and a downward inclined-face (43) on the supporting member (45) and the dielectric (37), respectively. Further, a discharge gas can be supplied uniformly to a discharge region (51) through the electrode (32) and the dielectric (37), both of which are porous. Many gas exhaust ports (41), by which the flow rate of the gas can be regulated, are provided around the discharge region (51). Thus, the gas is uniformly exhausted around the discharge region (51). Especially, if the gap between the dielectric (37) and a work (39) depends on mounting accuracy or the like and varies with location, the gas can be exhausted uniformly around the discharge region (51).

    摘要: A hood safety stop mechanism for restricting backward movement of a hood, which is bendable convexly upward relative to the car body during a front-end collision of a vehicle, includes an elongated opening formed in either the hood or the car body, and a hook, secured to the other of the hood and car body. The hook is formed so as to be located within the opening without any engagement with an edge of the opening. During a collision, the hook is initially brought into engagement with the edge of the opening when the hood begins to open and after the hood has opened to a predetermined engaging angle. The hook is then disengaged from the opening when the hood begins to bend during further opening of the hood. Finally, the hood is fully bent to a predetermined bend angle.
