Patent number: 7073247Abstract: A method for metallurgically bonding a stator bar to a coupling to reduce the incidence of leak paths resulting from corrosion. The stator bar comprises strands through which a liquid coolant can flow. Adjacent ends of the strands are received in an interior cavity of the coupling through an opening in the coupling. A joining material is provided on a first portion of the stator bar within the coupling opening and adjacent the ends of the strands. The first portion is heated to melt the joining material. At essentially the same time, a second portion of the stator bar outside the coupling is also heated. Once the joining material is suitably molten, the first portion is allowed to cool while the second portion remains heated, thereby causing the joining material nearest the ends of the strands to solidify first.Type: GrantFiled: April 30, 2003Date of Patent: July 11, 2006Assignee: General Electric CompanyInventors: Raymond Grant Rowe, Alan M.

Patent number: 6983539Abstract: In one form of the invention, a laser beam propagates directly through bulk material of a TAB tape or base, to heat and form a bond between electrical leads formed on the base and aligned contact bumps.

Publication number: 20030234451Abstract: A new and improved electrical connector is provided for Ball Grid Array (BGA) devices and Direct Chip Attach (DCA) devices that solves the prior art problems of mismatch in the coefficient of thermal between a semiconductor die and its substrate, PC board or carrier. The electrical connector consists of a resilient loop of wire that is permanently wire bonded at a first and a second bond position to an electrode or contact pad of a die or an interposer. The closed loop of wire is stable in the X and Y direction and resilient in the Z direction which enables the wire bonded die or interposer to be temporarily attached to a carrier or test board for all forms of tests as well as being removable and reworkable even after being permanently soldered in place on a substrate or PC board. Since the loop shaped connectors are resilient in X, Y and Z directions, the die or interposer may be clamped onto a PC board or substrate to provide a lead free electrical connection that does not require any underfill.Type: ApplicationFiled: June 25, 2002Publication date: December 25, 2003Inventor: Eli Razon

Publication number: 20030229983Abstract: The method makes it possible to form a stator of an electric motor by means of a multiple-slide press (21, 22, 23). The starting point is a bundle consisting of rectilinear segments of sheets obtained by stamping and welded. The stator is formed by means of four successive operations carried out by four groups of slides of a multiple-slide press and corresponding dies. The cylinder formed is subsequently welded along its joining generatrix and is calibrated in a hydraulic press.Type: ApplicationFiled: March 13, 2003Publication date: December 18, 2003Inventor: Raymond Bourgeois

Patent number: 6647617Abstract: A method of constructing a mapping catheter is described where the catheter has numerous electrodes each associated with a single connection in a plug. The method consists of first arranging a plurality of wires in the desired relationship, with each of the wires running to a connection in a plug. Next, a single electrode is formed on each wire. Because it is often difficult to associate a particular connection with a particular plug, an electrical signal is then applied to a single one of the wires. The electrical signal can be applied to the connection or to the electrode. The electrical signal is then found among by examining either the electrodes or the connections, depending on which where the electrical signal was applied. Once the electrical signal is discovered, a map can be made between the connections and the electrodes.Type: GrantFiled: June 7, 2000Date of Patent: November 18, 2003Inventors: Graydon Ernest Beatty, Jonathan Kagan, Jeffrey Robert Budd

Patent number: 6604283Abstract: A method of manufacturing an electrode array has an elongate flexible carrier that is much more flexible in a first direction than in a second direction orthogonal thereto. The elongate flexible carrier is formed with a bias force that causes the array to flex in the first direction so as to assume the general spiral or circular shape of the scala tympani duct within the cochlea. The less-flexible direction is the direction that makes it difficult for the array to twist as it is inserted within the scala tympani duct. The bias force is sufficiently strong to cause the array to assume its preformed spiral shape even after being straightened during initial insertion into the cochlea. Electrode contacts, embedded into the carrier so as to be exposed along an inner or concave surface of the spiral, thus wrap snugly around the modiolus, thereby positioning the electrode contacts against the modiolar wall in an optimum position for stimulation.Type: GrantFiled: March 3, 2000Date of Patent: August 12, 2003Assignee: Advanced Bionics CorporationInventor: Janusz A.

Publication number: 20030136000Abstract: A process for treating a coil end is provided, by which upon automatic winding of the coil, an electric connection between a portion of a wire at the front or rear end of the coil and a terminal of a winding object by arc welding can be securely carried out. A stripping section strips an insulating coating off from the portions of the wire at the front and rear ends of the coil while the wire is wound around the winding object with the portions of the wire being bound to the terminal. Each portion of the wire, the insulating coating of which is stripped off, bound to the terminal is electrically connected to the terminal by arc welding.Type: ApplicationFiled: August 7, 2002Publication date: July 24, 2003Inventor: Yoshihide Goto

Publication number: 20030136579Abstract: Solder bumps are created on a substrate of an electronic assembly having lengths that are longer than the widths. The solder bumps are created by locating solder balls of power or ground connections close to one another so that, upon reflow, the solder balls combine. Signal solder balls however remain separated. Capacitors are created by locating power solder bumps adjacent ground solder bumps and extending parallel to one another.Type: ApplicationFiled: March 25, 2003Publication date: July 24, 2003Inventors: Damion T.
