Patent number: 7832079Abstract: The invention relates to a vacuum interrupter chamber and a method for producing the same according to the preambles of patent claims 1 and 3. In order here to improve a vacuum interrupter chamber of this type and a method for producing the same and the subsequent casting to the extent that the advantages described above are utilized but the disadvantages described are avoided, it is proposed according to the invention that, in preparation for later casting, the vacuum interrupter chamber (1) is provided on the outer surface with a protective sheath (2) consisting of an elastic or elastomeric or plastomeric material, which is applied to the surface of the vacuum interrupter chamber without further expanding mechanical aids by heat shrinkage alone.Type: GrantFiled: June 27, 2005Date of Patent: November 16, 2010Assignee: ABB Technology AGInventors: Oliver Claus, Hartmut Mildes, Till Rümenapp

Publication number: 20100281978Abstract: The present invention provides an inertial sensor and a producing method thereof. The inertial sensor measures the acceleration and angular acceleration of a moving object according to the sensed pressure difference (pressure gradient). The inertial sensor comprises a substrate; a circuit disposed on the substrate; a pressure device comprising an annular chamber that has a first end and a second end; a channel having a first end and a second end, with the second end being connected to the second end of the annular chamber; a pressure meter connected respectively to the first end of the annular chamber and the first end of the channel, wherein the pressure meter is electrically connected to the circuit; and a liquid filling the annular chamber. Hence, the present invention provides a highly sensitive planar inertial sensor, which simplifies the structure, makes easy the manufacturing process, and lowers the costs.Type: ApplicationFiled: December 26, 2007Publication date: November 11, 2010Applicant: Industrial Technology Research InstituteInventor: Pin Chang

Patent number: 7827660Abstract: A bimorphic structure responsive to changes in an environmental condition, sensor structures incorporating one or more of such bimorphic structures, and a method of forming such bimorphic structures. The sensor structure has an electrically-conductive first contact on a substrate, and a bimorph beam anchored to the substrate so that a portion thereof is suspended above the first contact. The bimorph beam has a multilayer structure that includes first and second layers, with the second layer between the first layer and the substrate. A portion of the first layer projects through an opening in the second layer toward the first contact so as to define an electrically-conductive second contact located on the beam so as to be spaced apart and aligned with the first contact for contact with the first contact when the beam sufficiently deflects toward the substrate.Type: GrantFiled: July 30, 2008Date of Patent: November 9, 2010Assignee: Evigia Systems, Inc.Inventors: Bishnu Prasanna Gogoi, Navid Yazdi

Patent number: 7829793Abstract: An additive process disk drive suspension interconnect, and method therefor is provided. The interconnect has a metal grounding layer of typically stainless steel or copper metallized stainless steel, a metal conductive layer and an insulative layer between the metal grounding layer and the conductive metal layer. A circuit component such as a slider is electrically connected to the conductive layer along a grounding path from the circuit component and the conductive layer to the metal grounding layer through an aperture in the insulative layer. For improved electrical connection a tie layer is provided through the insulative layer onto the grounding layer in bonding relation with the ground layer. A conductor is deposited onto both the conductive metal layer and the tie layer in conductive metal layer and tie layer bonding relation, and the circuit component is thus bonded to the grounding layer by the conductor.Type: GrantFiled: July 13, 2006Date of Patent: November 9, 2010Assignee: Magnecomp CorporationInventors: Christopher Schreiber, Christopher Dunn

Patent number: 7823268Abstract: The present invention relates to a method for the manufacture of a transducer unit for an angular switching device, in which a transducer element is inserted and fixed in an angled bush. The inventive method is characterized in that the transducer element is brought into aligned engagement with a transducer receptacle formed in a tool, that subsequently for the precise positioning with respect to the transducer element the bush is brought into an aligned, at least partial positive engagement with a bush receptacle appropriately constructed in the tool and that for completing the transducer unit the transducer element is fixed in the bush. In further aspects the invention relates to an angular transducer unit, an angular switching device and an object detection device.Type: GrantFiled: January 12, 2005Date of Patent: November 2, 2010Assignee: Pepperl + Fuchs GmbHInventor: Dierk Schoen

Patent number: 7824098Abstract: Mechanical transducers such as pressure sensors, resonators or other frequency-reference devices are implemented under conditions characterized by different temperatures. According to an example embodiment of the present invention, a combination of materials is implemented for mechanical transducer applications to mitigate temperature-related changes at or near a selected turnover temperature. In one application, a material property mismatch is used to facilitate single-anchor transducer applications, such as for resonators. Another application is directed to a Silicon-Silicon dioxide combination of materials.Type: GrantFiled: January 21, 2008Date of Patent: November 2, 2010Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Renata Melamud, Bongsang Kim, Matthew Hopcroft, Saurabh Chandorkar, Manu Agarwal, Thomas W.
