The method can further include positioning the first hardware device in contact with a machined interface of the composite part and machining the part including drilling a plurality of positioning holes through the hardware device and the part while the part is on the lay-up tool. The machining can include machining the sacrificial portion creating a machined interface and positioning the hardware device on the machined interface.Type: GrantFiled: May 2, 2003Date of Patent: November 28, 2006Assignee: The Boeing CompanyInventors: Dwight L. Engwall, John F. Costello

Patent number: 7111374Abstract: Improved drilling and pinning machines and methods for processing elongate flexible e.g. rubber strips of seal material for forming seals about openings. The machines and methods form precisely positioned holes in the rubber strip, and insert pins in the holes. Opposing ends of the pins are ultimately received in cooperating holes in the opening, mounting the seal strip to the opening. Machines and methods of the invention temporarily fix a strip or portion of the seal material to a rigid component of the machine. While the seal material is fixedly held, first and second holes are formed in general alignment with the length of the strip, or a subsequent hole is formed wherein location of the subsequent hole is based on location of a previously-formed hole. The formed holes and/or inserted pins are automatically inspected. The inspection information is forwarded to, and used by, the machine controller.Type: GrantFiled: April 1, 2003Date of Patent: September 26, 2006Inventor: John Howard Stewart

Patent number: 7056459Abstract: A method for manufacturing shoe components using EVA copolymer of film shape having a thickness of 0.01 to 2 mm, preferably 0.1 to 1.0 mm and a surface roughness variations which cannot be easily discriminated through touch or sight, and a shoe component manufactured by the method are provided. The method overcomes the drawbacks caused during the process of manufacturing a shoe component with different mechanical physical properties or colors. The method allows for ease of manufacture of a shoe component with two or more types of colors or physical properties, through a single foam molding process using a film with less variation and ease of processing, to thereby simplify manufacturing procedures and reduce manufacturing costs. In addition, a high quality shoe component with no additional seam-line is obtained.Type: GrantFiled: June 25, 2003Date of Patent: June 6, 2006Inventor: Hyung Jun Park

Patent number: 7022276Abstract: A method for manufacturing a circuit board with high thermal dissipation includes the following steps: preparing a thermal conductive resin composition including 70 to 95 mass % of an inorganic filler and 5 to 30 mass % of a resin composition that includes a liquid thermosetting resin, a thermoplastic resin powder, and a latent curing agent; bonding the thermal conductive resin composition and a metal foil together by heating at a temperature lower than a temperature at which the thermosetting resin starts to cure while applying pressure so that the thermal conductive resin composition increases in viscosity and thus is solidified irreversibly; providing holes and curing the thermosetting resin to form an insulating substrate; and forming through holes and a circuit pattern. This method can achieve improved productivity and low cost in processing the holes. It is preferable that the thermal conductive resin composition is integral with a reinforcing material.Type: GrantFiled: June 19, 2003Date of Patent: April 4, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Koichi Hirano, Yoshihisa Yamashita, Seiichi Nakatani

Patent number: 7022275Abstract: Saddle made of composite material, in particular for a bicycle, comprising a support structure provided with a padding having a seating surface. The support structure comprises a plurality of first layers of high-rigidity composite material having an opening formed centrally therein and a second layer of composite material with a rigidity less than that of the first layers, fixed to the latter along a superimposed surface covering the opening so as to form an elastically yielding zone which is preferably located in the prostatic and ischiatic zones of the seat of the saddle.Type: GrantFiled: October 10, 2003Date of Patent: April 4, 2006Assignee: Selle Royal S.P.A.Inventor: Riccardo Bigolin
