Patent number: 8091459Abstract: A method for manufacturing a rotary tool for chip removing machining with at least one chip flute that extends in the longitudinal direction of the tool. The method involves preparing a mixture of a cemented carbide, cermet or ceramics powder and a carrier, such as a polymer, and placing the mixture in an extruding machine. The mixture is extruded in a feed direction by means of a die to form the diameter of the mixture body. The mixture body passes against a chisel which forms a chip flute in the outer periphery of the mixture body by chip-removing machining. When the chisel is displaced away from the mixture body, a non-fluted shaft portion is formed. By rotating the mixture body while contacted by the chisel, a helical chip flute can be formed. Alternatively, the body could be twisted after a straight flute has been formed, whereupon the flute becomes helical.Type: GrantFiled: December 28, 2007Date of Patent: January 10, 2012Assignee: Sandvik Intellectual Property AktiebolagInventors: Jören Kugelberg, Roine Ericsson, Jonathan Fair, Anders Micski

Patent number: 7481901Abstract: A method for manufacturing a wiring board offering efficient operations of peeling and collection of a protective film as well as preventing a lowered yield. A method for manufacturing a build-up multilayer resin wiring board, which includes a taping process S2 and a peeling process S3. In the taping process S2, two sheets of substrate are supported and adjoined under the condition that the edges thereof are placed close to each other, and a tape is affixed so that the protective film may be connected on the edge of the substrate. In the peeling process S3, the protective films connected to each other are continuously peeled by sequentially lifting them via the tapes so that an interlayer insulation material may remain on the substrate.Type: GrantFiled: December 1, 2005Date of Patent: January 27, 2009Assignee: NGK Spark Plug Co., Ltd.Inventors: Yasushi Toyoda, Nobuyuki Tanaka

Publication number: 20080196237Abstract: A method and apparatus for manufacturing a honeycomb compact-body molding die having material feed bores for supplying material therethrough and slit recesses formed in a polygonal lattice pattern to mold the material in a compact body with a honeycomb shape are disclosed. The slit recesses are formed on a recess forming surface of the molding die using an electrode having electrode segments, formed in a lattice pattern corresponding to shapes of the slit recesses each of which has a wall thickness of 0.1 mm or less, to generate an electrical discharge between the molding die and the electrode to form the slit recess on the molding die. When the electrode is worn by a given amount, an apical end cut-off processing step is executed to cut off an apical end of the electrode using a dress plate to expose a new apical end formed with an electrical discharge surface.Type: ApplicationFiled: February 19, 2008Publication date: August 21, 2008Applicant: DENSO CORPORATIONInventors: Kiyofumi Shinya, Isao Katsura, Mamoru Oonishi

Publication number: 20080194080Abstract: A method for dicing an optoelectronic semiconductor wafer has steps of preparing an optoelectronic semiconductor wafer, laser scribing, diamond saw dicing and forming optoelectronic semiconductor dies. A product for dicing an optoelectronic semiconductor wafer has a substrate and an epitaxial layer. The substrate has a first surface, a second surface and two rough surfaces. The rough surfaces are formed by laser scribing the wafer to define multiple guide grooves on the wafer and diamond saw grooving the wafer along the guide grooves. The epitaxial layer is formed epitaxially on the first surface of the substrate.Type: ApplicationFiled: February 13, 2007Publication date: August 14, 2008Inventors: Chih-Ching Cheng, Chiung-Chi Tsai

Patent number: 7316174Abstract: When a plate-shaped material, such as a CSP substrate, that does not require exact precision is divided, a cutting machine is provided with not only first and second chuck tables, but also first and second cutting units. Then, each plate-shaped material, which is placed on a respective chuck table, is aligned immediately before it is cut, so that the Y-axis index control and the X-axis cutting movement control are established for cutting by the cutting units. A cutting portion is cut in the first direction by the first cutting unit according to the Y-axis index control and the X-axis cutting movement control, and subsequently a cutting portion is cut in the second direction by the second cutting unit. Hence, the cutting portions of the plate-shaped materials placed on the first and second chuck tables are cut by the first and second cutting units by sharing a role.Type: GrantFiled: December 16, 2004Date of Patent: January 8, 2008Assignee: Disco CorporationInventor: Kazuma Sekiya
