Publication number: 20110168677Abstract: Electric welding method is provided of aluminium or aluminium alloy in a magnetic field, the aluminium or aluminium alloy adjacent to a weld joint under formation has an oxide layer, and the free end of a welding wire is supplied with a surrounding shielding gas. Furthermore, a welding wire is used that comprises aluminium or aluminium alloy provided with an oxide-inhibiting coating, which forms the outer covering or sheath of the welding wire and/or that as said shielding gas there is used a shielding gas with oxygen incorporated therein, or that the shielding gas is supplied with oxygen during the welding process. When the process is carried out in a magnetic field, the minimum frequency of the welding current is selected as a function of the strength of the magnetic field. A method is also provided for producing the welding wire and necessary material conditions for a usable welding gun.Type: ApplicationFiled: December 17, 2008Publication date: July 14, 2011Applicant: EFD INDUCTION A.S.Inventor: Ketil Hornaes

Publication number: 20100078330Abstract: A conductive surface 5 of a film 4 is plated with copper by allowing the film 4 to pass through a plating solution 7 in a plating bath 6 while conveying the film in a direction indicated by the arrow. Air knife devices 20A and 20B are disposed between the plating solution 7 and a next cathode roller 1B so as to face a conductive surface 5 of the film 4. The air knife devices 20A and 20B remove liquid and moisture on the conductive surface 5 by jetting heated air to the conductive surface 5 drawn out of the plating solution 7. Accordingly, even when the conductive surface 5 comes in contact with the next cathode roller 1B, developed silver is not dissolved, thereby preventing the silver contamination of the cathode rollers 1B and 1C.Type: ApplicationFiled: June 20, 2006Publication date: April 1, 2010Applicant: FUJIFILM CORPORATIONInventor: Tomoyoshi Hyodo

Patent number: 7678242Abstract: Disclosed is a system and a method for manufacturing flexible copper clad laminate film capable of efficiently electroplating both surfaces of a polyimide-based film to form copper plating layers thereon while making it easy to repair and maintain the apparatus or clean its plating or cleaning bath. The system includes a pickling device adapted to spray a pickling liquid to both surfaces of a to-be-plated film to remove oxide coatings from the copper coatings; a number of water-cleaning devices for removing the pickling liquid and copper electrolyte remaining on the film; at least one plating device positioned between the water-cleaning devices to form copper plating layers on both surfaces of the film; an antirust device for preventing the copper plating layers, which have been formed by the plating device, from rusting; and a drying device for drying the antirust liquid on the film, which has been subjected to antirust treatment.Type: GrantFiled: December 5, 2005Date of Patent: March 16, 2010Assignee: Korea Institute of Industrial TechnologyInventors: Hong Kee Lee, Seong-Ho Son, Seok Bon Koo
