Abstract: A surface chemical treatment apparatus provided with: a first conduit having an opening at one end and communicating with a liquid supply means at the other end; a second conduit having at one end an opening that surrounds the opening of the first conduit and communicating with a liquid suction means at the other end; and a moving mechanism for moving the openings of the first and second conduits relative to the solid phase surface, so as to make a surface chemical treatment possible in a fine pattern by allowing the patterning solution to be dispensed through the opening of the first conduit while allowing the solution to be suctioned up together with the surrounding liquid phase or gas phase medium through the opening of the second conduit that surrounds the opening of the first conduit and, thus, preventing seepage of the solution in all directions.

Abstract: A method of manufacturing a full face vehicle wheel having a high durability performance, in which the back surface of a wheel disk is provided in advance with an annular joining groove. A peripheral joining end of a wheel rim is provided in advance with an inside slope end surface. The peripheral joining end is seated and positioned on the bottom surface of the annular joining groove. A welding heat confining annular region is produced between the inside groove wall of the annular joining groove and the inside slope end surface. The annular joining groove and the peripheral joining end are joined by welding.

Abstract: A first thermoplastic resin film is laid on a heated endless belt to be moved together with the endless metal belt, a second thermoplastic resin film is superposed on the first thermoplastic resin film laid on the belt, and the first and second thermoplastic resin films laid on the belt are touch-rolled by a combination of the belt and a second roller to be laminated. The second thermoplastic resin film can be superposed on the first thermoplastic resin film laid on the belt after being touched to the second roller. A thermally produced molding is obtained by heat treating the laminated thermoplastic resin film.
