Patent number: 8393523Abstract: A method of performing ultrasonic stir welding uses a welding head assembly to include a plate and a rod passing through the plate. The rod is rotatable about a longitudinal axis thereof. In the method, the rod is rotated about its longitudinal axis during a welding operation. During the welding operation, a series of on-off ultrasonic pulses are applied to the rod such that they propagate parallel to the rod's longitudinal axis. At least a pulse rate associated with the on-off ultrasonic pulses is controlled.Type: GrantFiled: June 14, 2012Date of Patent: March 12, 2013Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventor: R. Jeffrey Ding

Publication number: 20130004685Abstract: A method for sealing the curved vacuum glass comprises: first preparing metallized layer bonded with the glass plate on the edge surface of the curved glass to be sealed by locally heating the metal slurry coating; then air-tightly sealing the edges of two glass plates by using the metal brazing technology, or air-tightly sealing the edges of two glass plates by air-tightly welding the metal sealing sheet between the metallized layers of two glass plates to be sealed. A curved vacuum glass is also provided. The method makes the sealing part have firm connection, good air tightness and good thermal shock resistance. The sealing structure made of the metal sealing sheet is well compatible with the temperature deformation caused by the temperature difference between the internal and external glass plates of the vacuum glass.Type: ApplicationFiled: October 29, 2010Publication date: January 3, 2013Applicant: LUOYANG LANDGLASS TECHNOLOGY CO., LTDInventors: Yanbing Li, Zhangsheng Wang

Publication number: 20120205423Abstract: A wire end processing method includes tree steps. In a core wire portion exposing step, a sheath of a wire is stripped so as to expose a core wire portion composed of a plurality of element wires. In a core wire portion unifying step, ultrasonic vibration is applied to the exposed core wire portion while applying a pressure thereto, thereby causing the plurality of the element wires to rub against one another so as to unify the core wire portion. In a terminal connecting step, the unified core wire portion is press-contacted or press-fitted to the terminal.Type: ApplicationFiled: January 18, 2011Publication date: August 16, 2012Applicant: YAZAKI CORPORATIONInventor: Tsutomu Takayama
