Patent number: 7305754Abstract: In manufacturing a chip resistor by dividing a chip resistance substrate which includes an insulator, resistance film formed on a surface of the insulator, and a plurality of conductive strips disposed on the resistance film at fixed intervals, grooves are formed by removing a predetermined width of the resistance film including at least second prescribed severing lines. After forming the grooves, the chip resistance substrate is severed in longitudinal and lateral directions along first prescribed severing lines for dividing the conductive strips into two parts and the second prescribed severing lines perpendicular to the first prescribed severing lines so as to produce discrete chip resistors.Type: GrantFiled: November 18, 2004Date of Patent: December 11, 2007Assignee: Disco CorporationInventors: Kazuma Sekiya, Toshiaki Takahashi

Patent number: 7294394Abstract: According to one aspect of the invention, a structure and method for providing improved thermal conductivity of a thermal interface material (TIM) made of phase changed polymer matrix and a fusible filler material is disclosed. The TIM may also have a non-fusible filler material and a percentage of a non-phase change polymer added to the phase change polymer matrix. The TIM, used to mate and conduct heat between two or more components, can be highly filled systems in a polymeric matrix where the fillers are thermally more conductive than the polymer matrix.Type: GrantFiled: May 13, 2005Date of Patent: November 13, 2007Assignee: Intel CorporationInventors: Saikumar Jayaraman, Paul A. Koning, Ashay Dani

Patent number: 7290324Abstract: A magnetic head including a media heating device. Following the fabrication of the heating device, a sacrificial layer of material is deposited to protect the heating device during subsequent process steps. Thereafter, write head components, such as write head induction coils and/or a P1 pole pedestal are fabricated above the heating device, and the sacrificial layer is substantially consumed in protecting the heating device during the aggressive etching and milling steps used to create those components. Further components, including a second magnetic pole are thereafter fabricated to complete the fabrication of the write head portion of the magnetic head. The sacrificial layer may be comprised of alumina, or a material such as NiFe that can act as a seed layer for a subsequent head components such as the P1 pole pedestal.Type: GrantFiled: September 19, 2005Date of Patent: November 6, 2007Assignee: Hitachi Global Storage Technologies Netherlands, B.V.Inventors: Robert E. Fontana, Jr., Jeffrey S. Lille

Patent number: 7281318Abstract: A method of manufacturing a composite structural member with an integrated electrical circuit is provided. The structural member includes a plurality of layers of structural reinforcement material, and two or more electrical devices are disposed at least partially between the layers with an intermediate layer of the structural reinforcement material disposed between the electrical devices. At least one electrical bus is disposed in the structural member, and each electrical device is connected to the bus by a conductive electrode. Thus, the electrodes can extend through the intermediate layer of the structural reinforcement material to connect each of the electrical devices to one or more of the buses.Type: GrantFiled: May 19, 2004Date of Patent: October 16, 2007Assignee: The Boeing CompanyInventors: Joseph A. Marshall, Douglas B. Weems, Richard C. Bussom, David M. Anderson
