Publication number: 20130335484Abstract: An ink jet print head can be formed using a laser to melt a plating layer interposed between a piezoelectric actuator and a circuit layer bump. The plating layer can be formed on the circuit layer bump, the piezoelectric actuator, or both, and a laser beam output by the laser is used to melt the plating layer to provide a laser weld. In another embodiment, the circuit layer bump or the trace itself functions as the plating layer, which is melted using a laser to provide the laser weld.Type: ApplicationFiled: June 15, 2012Publication date: December 19, 2013Applicant: XEROX CORPORATIONInventors: Bradley James GERNER, Peter J.

Patent number: 8610026Abstract: The method of lap-welding of metal plates using a laser beam, wherein at least one of the metal plates is surface-treated, includes putting a metal plate on the other metal plate and forming a gap between the metal plates so that gas generated at the treated surface at the time weld can be dissipated therethrough. A surface-treated first work and a surface-treated second work are placed one on the other and clamped by a clamp with an opening of the clamp centered at the location on the first work to be welded. Then a laser beam is directed to the location to form a weld. The beam is then directed near the inner periphery of the opening to form a heated portion so that the heated portion deflects to form a gap through which the gas generated at the treated surface dissipates thereby reducing gas pressure.Type: GrantFiled: December 2, 2009Date of Patent: December 17, 2013Assignee: Honda Motor Co., Ltd.Inventors: Haruhiko Kobayashi, Satoshi Ohkubo, Shinichi Miyasaka, Koji Oda, Naoki Takahashi, Hideari Kamachi

Patent number: 8604382Abstract: There is provided a method for manufacturing a laser welded steel pipe in which the status of laser welding is accurately assessed, and the assessment is used to modify welding conditions, so that laser welded steel pipes can be manufactured at a high yield rate and in a stable manner. Irradiation point(s) of laser beam(s), with which the longitudinal edges are irradiated from the side of the outer surface, are monitored from the side of the inner surface of an open pipe, and then conditions of welding with the laser beam(s) are assessed to be kept unchanged if any keyhole is found penetrating out of the inner surface of the open pipe, or modified if no keyhole is found penetrating out of the inner surface of the open pipe.Type: GrantFiled: June 22, 2009Date of Patent: December 10, 2013Assignee: JFE Steel CorporationInventors: Koji Yano, Kenji Oi, Masahito Suzuki, Toshifumi Kodama, Shigeto Sakashita

Patent number: 8601834Abstract: The present invention provides a hermetically sealed container offering a strength and airtightness which are reliable over time. A joining member having a viscosity with a negative temperature coefficient, having a softening temperature lower than those of a pair of glass substrates and a frame member, and extending into a frame shape is arranged between one of the pair of glass substrates and the frame member so that the joining member contacts both the one of the pair of glass substrates and the frame member. Then, the joining member is heated and thermally melted while being pressed so that the center G of an incoming heat flux distribution in the width direction of the joining member is positioned at an inner space E rather than the center of the joining member in the width direction thereof.Type: GrantFiled: September 7, 2011Date of Patent: December 10, 2013Assignee: Canon Kabushiki KaishaInventors: Mamo Matsumoto, Tomohiro Saito, Nobuhiro Ito

Patent number: 8606093Abstract: The water heater (2) or steam generator comprises a chamber (4) in two sections (5, 6) formed in particular by stamping. Inside this chamber a heating element (8) is arranged, which has a spiral-shaped main section (10) and two end sections (11, 12) passing through two circular openings of the chamber. The two end sections are welded to the chamber by a laser beam such that the weld obtained is continuous and ensures a good mechanical fixture of the heating element and an adequate tightness for the water heater or steam generator. For this purpose, a flange (18) is arranged at the periphery of each opening. Moreover, the two sections of the chamber have a widened edge (28) to allow them to be welded effectively.Type: GrantFiled: March 14, 2012Date of Patent: December 10, 2013Assignee: LASAG AGInventors: Mario Montanaro, David Naman, Gustavo Beltrami

Patent number: 8604381Abstract: An integrated laser material processing cell allowing laser-assisted machining to be used in conjunction with directed material deposition in a single setup, achieving greater geometric accuracy and better surface finish than currently possible in existing laser freeform fabrication techniques. The integration of these two processes takes advantage of their common use of laser beam heat to process materials. The cell involves a multi-axis laser-assisted milling machine having a work spindle, a laser emitter, and means for positioning the emitter with respect to the spindle so as to direct a laser beam onto a localized area of a workpiece in proximity to a cutting tool mounted in the spindle. A powder delivery nozzle mounted on the machine and positioned adjacent to the emitter delivers powder to a deposition zone in the path of the beam, such that material deposition and laser-assisted milling may be performed substantially simultaneously in a single workspace.Type: GrantFiled: October 12, 2007Date of Patent: December 10, 2013Assignee: Purdue Research FoundationInventor: Yung C.
