Abstract: The present invention provides a plating film that exhibits good adhesion to glass substrates. The present invention is a plating film comprising an oxide layer, an electroless plating film, and an electrolytic copper plating film in this order.

Abstract: A fluid apparatus includes an air pump and a buffer tank. The buffer tank has an inlet receiving air delivered from the air pump into a storage space, and an outlet discharging the air from the storage space. The storage space contains a discharge flow passage extending from the outlet toward the inlet in the storage space. The discharge flow passage opens toward the inlet. The discharge flow passage has a tapering flow passage portion with a cross-sectional area gradually decreasing toward the outlet. Compressed air delivered from the inlet into the storage space diffuses in the storage space and is introduced into the discharge flow passage from an introduction opening and delivered from the outlet.

Abstract: Disclosed is a coating composition for a wiper blade, which includes a silicone-based wax, a silicone oil and a solid lubricant so that the silicon-based wax in a liquid phase dissolved in the silicone oil coexists with the solid lubricant for extended time periods. Also, a wiper blade is provided, which has a rib including a coating layer formed from the coating composition, so that upon operation of the wiper blade, components of the coating layer dissolve out of the surface of the coating layer and are then transferred onto a windshield due to friction between the wiper blade and the windshield, thereby forming on the surface of the windshield a water repellent film which is hard and has outstanding durability.
