The joining member is arranged at the joining portion of the first workpiece and the second workpiece, and abutting the first workpiece and the second workpiece. The friction surface of the joining tool is positioned to resist at least one of the first treating layer and the second treating layer. The joining tool is rotated and moved to agitate at least one of the first workpiece and the second workpiece, until at least part of the first workpiece and the second workpiece are plasticized and joined together. | 06-09-2011 |
20110132970 | FRICTION STIR METHOD - A friction stir welding method includes providing a joining tool, a mold comprising a top surface and a cutout defined from the top surface, and a workpiece comprising a treatable layer and arranged on the top surface of the mold. The joining tool resists the workpiece, and rotates and moves to agitate the treatable layer of the workpiece along an extending direction of the cutout of the mold, until a protrusion integrated with the workpiece is formed in the cutout of the mold. | 06-09-2011 |
20110135954 | FRICTION STIR WELDING METHOD AND FRICTION STIR WELDED HOUSING - A friction stir welding method utilizes a joining tool comprising a friction surface, a first workpiece comprising a first treating layer and a first joining surface angled to the first treating layer, and a second workpiece comprising a second treating layer and a second joining surface joining the first joining surface of the first workpiece. The first workpiece is angled or perpendicular to the second workpiece such that the first treating layer is angled or perpendicular to the second treating layer. The first treating layer abuts the second treating layer. The friction surface of the joining tool resists the first treating layer of the first workpiece and the joining tool is rotated and moved to agitate the first workpiece until at least part of the first workpiece and the second workpiece are plasticized and joined together. | 06-09-2011 |
20120002618 | WIRELESS PACKET TRANSMISSION APPARATUS AND PACKET PRIORITY CONTROL SCHEDULING METHOD - A wireless packet transmission apparatus of this invention includes a packet priority controller that controls the order of transmitting packets with different priorities, and an adaptive modulation controller that changes the modulation scheme of the packets. The packet priority controller includes: a schedule selector that, when a modulation scheme is changed, with respect to packets with a priority of a predetermined value or more, provisionally sets a strict priority control scheme; and a comparison section that compares the transmission rate of the packets for which the strict priority control scheme is provisionally set and the transmission rate of the wireless packet transmission apparatus that is determined by the modulation scheme that has been changed by the adaptive modulation controller. Based on the comparison result, the schedule selector determines whether or not to set the strict priority control scheme for the packets for which the strict priority control scheme is provisionally set. | 01-05-2012 |
