Recycling Method for Tantalum Coil for Sputtering and Tantalum Coil Obtained by the Recycling Method
Publication number: 20140174917Abstract: The present invention relates to a method for recycling a tantalum coil for sputtering that is disposed between a substrate and a sputtering target. The method for recycling a tantalum coil for sputtering is characterized in that the whole or partial surface of a spent tantalum coil is subject to cutting (cutting is performed until a re-deposited film and knurling traces are eliminated) so as to eliminate the re-deposited film that was formed during sputtering, and knurling is newly performed to the cut portion. While sputtered grains are accumulated (re-deposited) on the surface of the tantalum coil disposed between the substrate and the sputtering target during sputtering, by eliminating the sputtered grains accumulated on the spent coil by way of cutting after the sputtering is complete, the tantalum coil can be efficiently recycled. Thus, provided is technology capable of lean manufacturing of new coils, improving productivity, and stably providing such coils.Type: ApplicationFiled: September 14, 2012Publication date: June 26, 2014Applicant: JX NIPPON MINING & METALS CORPORATIONInventor: Shiro Tsukamoto -

Publication number: 20110036928Abstract: The subject invention concerns methods revealing surface imperfections on an object comprising the steps of: coating the surface to be inspected with a composition comprising an opaque, water-dispersible liquid, sufficiently surface-adherent and with surface-wetting properties as to create a gloss finish, at least before the liquid dries, on the restored area; inspecting the surface to check for imperfections; and removing said composition with water. The method may also include a step of marking the surface, through the wet composition layer, to indicate the location of imperfections discovered. Also described are compositions and delivery systems suitable for carrying out the method comprising aqueous dispersions of a pigment and a resin, especially a polysaccharide resin.Type: ApplicationFiled: February 19, 2008Publication date: February 17, 2011Inventors: Dean William Dredge, Shaun Barry Knight

Publication number: 20100294016Abstract: A system and method for removal of dents from wind turbine masts uses a dent pushing tool. The dent pushing tool includes a self aligning ram assembly with a central ram cylinder and removable adjustable length arms. At the end of one arm is a curved base. At the end of the other arm is a dent pusher plate. Removal of the dent is caused by extension of the central ram cylinder.Type: ApplicationFiled: May 20, 2010Publication date: November 25, 2010Inventor: Hugh C. Barr

Patent number: 7823261Abstract: The inventive subject matter relates to methods for reconditioning a barrel previously used for containing a substance, comprising the steps of determining cutting parameters specific to the barrel material to provide controlled cutting of the barrel material; removing a desired depth of the barrel material using an automated high pressure water cutting device; testing for a remnant of the substance using a sensor device; optionally spraying with a dissolving agent; and repeating the steps of removing and testing upon detecting the presence of the substance in or on the barrel. Additionally, the inventive methods comprise applying a liquid to the wood of the reconditioned barrel to control evaporation of the barrel contents.Type: GrantFiled: October 30, 2006Date of Patent: November 2, 2010Inventor: Eugene Joseph Rogers

Patent number: 7765667Abstract: A reversible flange plate for refinishing differently configured brakes on a brake lathe adapter is provided. The reversible flange plate includes a body formed with a hollow bore extending substantially through the center of the body. Opposing rings adjacent the bore are provided for holding a brake during operation of the brake lathe. Opposing lips are provided that extend inwardly from the bore from the peripheral edge of the reversible flange plate, and include a ledge that is engageable with a plane of the brake during operation. In addition, an annular disc is provided with a ledge, between the opposing rings and the opposing lips, for further engagement with a plane of the brake during operation. This abstract is provided to comply with rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure, but this abstract is not to be used to interpret or limit the scope or meaning of any claim.Type: GrantFiled: March 1, 2006Date of Patent: August 3, 2010Assignee: Sun Systems, Inc.Inventor: Kenneth Turos

Patent number: 7761993Abstract: A method for increasing the fatigue life of a blade root of a turbomachine blade, wherein the blade root has at least one slot for back-gripping fixing of the blade root in a shaft component or a casing component of a turbomachine. The method comprises impressing a mechanical stress field in the notch root in a section of the slot, wherein the impressed mechanical stress field brings about a plastic deformation of the notch root. The impressed mechanical stress field is then progressively moved in the slot longitudinal direction of the slot. After this, the impressed mechanical stress field is removed again, wherein residual compression stresses remain in the notch root of the slot in the region of the slot in which the mechanical stress field was impressed.Type: GrantFiled: August 14, 2007Date of Patent: July 27, 2010Assignee: Alstom Technology LtdInventors: Alexander Mahler, Jian Chen

Publication number: 20100123034Abstract: The invention relates to a chipper knife of the type that is adapted to be mounted in chippers which have a rotatable tool, in the form of a disc, drum or frustoconical member, on which are mounted a plurality of such chipper knives to provide, during rotation of the tool and simultaneous feeding of pieces of wood to the same, material-cutting working or disintegrating of the pieces of wood into chips. The chipper knife comprises at least one cutting edge (7) which is defined between two edge-forming surfaces (9, 10) at an acute angle to each other. At least one of the two edgeforming surfaces is formed with a thickened cutting edge portion (12) in the area next to the cutting edge, said thickened cutting edge portion having a shoulder edge (13) toward the rest of the edge-forming surface and forming an angle to, or having a different centre of curvature to, the rest of the edgeforming surface. The invention also relates to a method of manufacturing such a chipper knife.Type: ApplicationFiled: January 8, 2008Publication date: May 20, 2010Inventor: Mats Engnell

Patent number: 7587824Abstract: A method for rebuilding a flow control valve, may be performed by first providing a flow control valve having a rotor positioned in a chamber of a valve body. The rotor has a valve stem. A top cover plate is mounted to the valve body above the rotor and has a first bore through which the valve stem protrudes. The top cover plate is removed so the rotor can be removed from the valve body. A seal is positioned on the top cover plate along the first bore so that when the rotor and top cover plate are placed in or on the valve body, the flow control valve is sealed at the interface between the top cover plate and the valve stem.Type: GrantFiled: September 5, 2006Date of Patent: September 15, 2009Assignee: General Electric CompanyInventors: Muhammad Pervaiz, Richard Scardina
