Patent number: 9488057Abstract: A micro jet gas film generation apparatus aims to eject a gas to a work object which is desired for cooling or insulating from heat. The micro jet gas film generation apparatus has a spout formed at a diameter of 5-100 ?m to generate a gas film on the work object. As the diameter of the spout of the micro jet gas film generation apparatus is small, the micro jet gas film generated from the spout cannot produce a large eddy due to the lack of sufficient energy, hence can maintain a thin film after a long distance ejection to improve cooling and heat insulation performance. Moreover, due to the small diameter of the spout, it also consumes less gas and can reduce the amount of gas required.Type: GrantFiled: June 10, 2014Date of Patent: November 8, 2016Assignee: AERONAUTICAL SYSTEMS RESEARCH DIVISION NATIONAL CHUNG SHAN INSTITUTE OF SCIENCE AND TECHNOLOGYInventors: Dun-Zen Jeng, Chao-Ching Wang, Ting-Hua Chien, Chi Kao

Patent number: 8001684Abstract: An exemplary method for manufacturing flexible printed circuit board is provided. A metal foil is supplied from a first feeding roller. The metal foil has a first surface and a second surface on two opposite sides of the metal foil. A first coverlay having a number of first openings defined therein is supplied from a second feeding roller and laminated on the first surface of the metal foil. Electrical traces are formed with the metal foil. A second coverlay having a number of second openings defined therein is supplied from a third feeding roller and laminated on the second surface of the metal foil. Each of the second openings registers with the respective first opening so that the electrical traces are exposed from the corresponding first and second openings. The method can improve quality and efficiency of manufacturing flexible printed circuit boards in a hollowed out form.Type: GrantFiled: December 18, 2007Date of Patent: August 23, 2011Assignee: Foxconn Advanced Technology Inc.Inventors: Chia-Cheng Chen, Chao-Ching Wang, Chiang-Hua Huang, Cheng-Hsien Lin

Publication number: 20100117462Abstract: A damper power-generating system includes a damper, a driving apparatus, and a generator. The driving apparatus simply consumes energy to do work for generation of electric power. That is, the work is done by utilizing the displacement due to the strong up-and-down vibration within a damper, wherein the displacement due to the up-and-down vibration drives a set of gear racks, which, in turns, drives gears having a one-way driving apparatus, so that rotation can be achieved in one direction, and, further, buffering springs and accelerative gears are used, so that speedy and uniform rotation can be achieved.Type: ApplicationFiled: November 12, 2008Publication date: May 13, 2010Inventors: June-Chi WANG, Hon-Wei Hsiao, Dun-Zen Jeng, Chao-Ching Wang
