Patent number: 6783623Abstract: A method of making a spirally wound dry bonded paperboard structure. The method includes adding a radio frequency active adhesive to the paperboard pulp stock during the paperboard fabrication process to first produce an RF active adhesive impregnated paperboard. The impregnated paperboard is then exposed to an RF energy field prior to or during winding, which activates the adhesive. The invention eliminates the need to apply a water-based adhesive to the paperboard prior to forming the structure, thereby reducing water migration into the paperboard.Type: GrantFiled: October 23, 2002Date of Patent: August 31, 2004Assignee: Sonoco Development, Inc.Inventors: Jeremy E. Morin, Krishnaraju Varadarajan

Patent number: 6770968Abstract: A method for bonding heat sinks to packaged electronic components comprises the steps of: (a) exposing to a plasma a surface of a molded polymer formed on a substrate; (b) allowing the plasma to at least partially convert silicon-containing residue on the surface to silica; and (c) bonding an article to the surface by applying an adherent between the article and the surface. Often, the silicon-containing residue is silicone oil, a mold release compound, which may prevent the formation of a bond when using conventional bonding methods and materials. The silica layer formed on the surface of the molded polymer assists in formation of a proper bond. The plasma may be an oxygen plasma and the adherent may be selected from either a heat cured silicone-based paste adhesive with a metal oxide filler or a heat cured porous polymer film impregnated with adhesive.Type: GrantFiled: February 19, 2003Date of Patent: August 3, 2004Assignee: International Business Machines CorporationInventors: Frank D.

Patent number: 6752888Abstract: The present disclosure relates that constraining a substrate into a convex arc prior to mounting and affixing of any chips, allows those chips to achieve exemplary final chip-to-chip abutment when the substrate is released and allowed to return to stasis. This is particularly of use where there are any intervening thermal cycles, and the thermal temperature coefficients of expansion for the chip/die and any substrate/mount are significantly different. This will allow the utilization of otherwise more desirable materials for the substrate in spite of some mismatch in thermal coefficients that may exist between the substrate and chips.Type: GrantFiled: December 12, 2001Date of Patent: June 22, 2004Assignee: Xerox CorporationInventors: Paul A. Hosier, Kraig A. Quinn

Patent number: 6748995Abstract: An apparatus having several stations that receive, apply adhesive to, crowd, press and cure the wood pieces into a continuous wood panel. A singulation station engages an individual one of the wood pieces oriented in a cross-machine direction from an infeed station, presents the wood piece to an adhesive station for adhesive application and releases the wood piece for crowding at a crowding station into a batch of the wood pieces. A press station downwardly presses the batch with an upper platen and presses the batch in a downstream direction onto the continuous wood panel with a clamping device. A radio frequency device applies radio waves to cure the adhesive between the wood pieces of the batch so as to adhere the wood pieces together and so as to adhere the batch to the continuous wood panel. A cutting station cuts individual wood panels from the continuous wood panel.Type: GrantFiled: August 23, 2001Date of Patent: June 15, 2004Assignee: Radio Frequency Services, Inc.Inventors: Thomas Gorich, Lee Kidd, Mike Bicio, Greg Sprole

Patent number: 6740191Abstract: A process for forming a heat weld between a catheter shaft and a surrounding balloon comprises selecting an elongate catheter shaft formed of thermoplastic polymeric material that is opaque to red and near-infrared light, and selecting a balloon formed of thermoplastic polymeric material that is transparent or translucent to red and near-infrared light. While a neck of the balloon is fitted in close contact around a distal portion of the catheter shaft, a laser beam of red and near-infrared light is applied through the balloon neck to impinge on the underlying opaque distal shaft, which is heated thereby. Heat from the shaft is conducted into the surrounding balloon neck so that adjacent annular portions of both components melt and mix. The molten materials are allowed to cool, forming a secure weld joint between the neck and the shaft. The process yields strong, flexible bonds between balloons and catheter shafts that may be selected from a wide variety of materials.Type: GrantFiled: February 22, 2001Date of Patent: May 25, 2004Assignee: Medtronic AVE, Inc.Inventors: Gerry Clarke, Gerard M.
