Patent number: 7137190Abstract: A process is described for fabricating magnetic transducers with metallic thin films with a corrosion resistant surface produced by exposing the thin films to a nitrogen in a plasma chamber. The exposure to the nitrogen is believed to increase the corrosion resistance of the metallic thin films by causing nitrides to form in a thin surface region. In the preferred embodiment the thin film metals of a magnetic transducer are treated with the nitrogen after being cut from the wafer and lapped. Typical metals used in magnetic transducers are NiMn, FeMn, NiFe, cobalt, CoFe, copper, IrMn and PtMn. The films may be further protected by the addition of prior art protective layers such as carbon.Type: GrantFiled: October 3, 2002Date of Patent: November 21, 2006Assignee: Hitachi Global Storage Technologies Netherlands B.V.Inventors: Yiping Hsiao, Cherngye Hwang, Jila Tabib

Patent number: 7127802Abstract: A method for fabricating a composite plate for a magnetic resonance imaging magnet. The method including cutting a starting plate having oppositely-directed major surfaces into a plurality of strips. Each of the strips having a width of approximately greater than 9 inches and faces which originally constituted parts of the major surfaces of the starting plate. The strips may be positioned to form the composite plate such that the width of each of the strips is equal to a thickness of the composite plate and the faces of the strips confront one another.Type: GrantFiled: September 16, 2004Date of Patent: October 31, 2006Assignee: Fonar CorporationInventors: Jevan Damadian, John Linardos, Gordon T.

Patent number: 7120993Abstract: On a surface of a glass cloth adhered a mica layer sheet, a mixture of inorganic particles having a thermal conductivity of at least 5 W/mK, a resin, and a solvent is applied to form a layer of the mixture of the inorganic particles, the resin, and the solvent; the layer of the mixture is reduced in thickness using a doctor blade, followed by pressurizing to form a high thermally conducting layer; the mica layer sheet on which the high thermally conducting layer is disposed is cut to obtain a mica insulating tape; and the mica insulation tape is wound around a coil conductor. As a result, an insulated coil that is excellent in the voltage endurance characteristics and has a high thermal conductivity is manufactured.Type: GrantFiled: June 8, 2004Date of Patent: October 17, 2006Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Shigeyuki Yamamoto, Wataru Bito, Toshio Isooka, Koichi Goshima

Patent number: 7117575Abstract: In manufacturing a link plate for a roller chain, a band of sheet steel is intermittently forwarded along a path past series of dies, including rough punching dies and shaving dies. The punching dies and corresponding shaving dies are located symmetrically on opposite sides of an intermediate location along the path. The intermediate location coincides with a location at which the lateral deviation of the band reverses. Consequently, the outer peripheral surfaces of the plate and the inner peripheral surfaces of the connecting pin holes, both being formed by rough punching, are brought into very close alignment with the shaving dies.Type: GrantFiled: March 30, 2004Date of Patent: October 10, 2006Assignee: Tsubakimoto Chain Co.Inventors: Toshifumi Satou, Masatoshi Chadou

Patent number: 7114359Abstract: The invention relates to a method for producing bent spring rails from an endless spring band. The method is characterized by the following steps: continuous bending of a section of spring band; cutting the bent section of spring band into a spring rail; discontinuous reverse bending to reduce the internal stresses of the bent, cut-to-length spring rail by subjecting the spring rail to at least one reverse bending force and/or heat-treating the cut-to-length spring rails, the heat treatment being a low-temperature treatment in this case, preferably at a temperature of less than 200 *C.Type: GrantFiled: November 6, 2001Date of Patent: October 3, 2006Assignee: Valeo Systemes d'EssuyageInventors: Oliver Lenzen, Gerald Pachur, Oliver Blumenstock

Patent number: 7114241Abstract: A method of manufacturing a magnetic head device includes forming a thin film magnetic head element over a substrate, the thin film magnetic head element including a magnetoresistance (MR) element. The substrate is cut such that the MR element is exposed on a side surface of the substrate. The side surface is then polished. Afterward, a magnetically degenerated layer is removed from the thin film magnetic head element along the side surface. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.Type: GrantFiled: November 21, 2001Date of Patent: October 3, 2006Assignee: Western Digital (Fremont), Inc.Inventors: Kazuyoshi Kubota, Masayuki Hamakawa

Patent number: 7106494Abstract: An apparatus for controlling propagation of incident electromagnetic radiation is described, comprising a composite material having electromagnetically reactive cells of small dimension relative to a wavelength of the incident electromagnetic radiation. Each electromagnetically reactive cell comprises a metallic element and a substrate. An electron population within the substrate near the metallic element of at least one of the electromagnetically reactive cells is temporally controllable to allow temporal control of an associated effective refractive index encountered by the incident electromagnetic radiation while propagating through said composite material.Type: GrantFiled: January 14, 2005Date of Patent: September 12, 2006Assignee: Hewlett-Packard Development Company, LP.Inventors: Viatcheslav V.

Patent number: 7104104Abstract: A duct structure (50), includes lengths of square/rectangular duct (52) manufactured by pre-forming the duct in round cross-section (51) and then transforming the round cross-section into square and rectangular cross-sections utilizing expandable die structures (58). The duct (52) may be connected together end to end by flanged connectors (54) formed from strip stock (71), that is notched at locations that correspond to the corners of the formed flange connector. The cross-sectional profile of the flanged connector is then formed by roll forming and/or bending and/or other techniques. Thereafter, the strip stock is bent at its notched locations to define the corners (80) of the flange connector (54) and then the free ends of the strip stock are fixed together.Type: GrantFiled: February 3, 2003Date of Patent: September 12, 2006Inventor: Jeffrey Allen Hermanson
