Patent number: 6675704Abstract: A solder paste stenciling apparatus for minimizing residue of solder paste includes a stencil having multiple stencil openings defined therein, a supporting member retaining the stencil, and a vibrator for vibrating the stencil. In operation, a substrate is engaged to a bottom surface of the stencil, and solder paste is applied onto a top surface of the stencil so that the stencil openings are filled with the solder paste. The substrate is then slowly separated from the stencil while the vibrator vibrates the stencil to evacuate the solder paste out of the stencil openings and to further deposit on the substrate. Hence, the amount of residual solder paste adhered to inner surfaces defining the stencil openings is minimized.Type: GrantFiled: March 6, 2002Date of Patent: January 13, 2004Assignee: Compeq Manufacturing Company LimitedInventors: Cheng-Yuan Lin, Sheng-Long Wu, Te-Chang Huang, Hao-Wei Liang, Pin-Hsuan Chang

Patent number: 5271784Abstract: A method for manufacturing a composite bicycle frame adapts stepped forming. The seat stays combined with the seat support means which are connected to parts of the top tube and seat tube, and the chain stays combined with the pedal support means which are connected to parts of the down tube and seat tube, are formed respectively. The seat stays connect to the chain stays by inserting a pair of rear wheel dropouts therebetween, to form substantially a pair of rear triangles of the bicycle frame. The seat tube and the steering support means connected to the top tube and down tube are laid up respectively. The cured rear triangles connect to uncured seat tube and steering support means associated with top tube and down tube, wherein the top tube, down tube, and seat tube form a front triangle. The front triangle is cured such that manufacturing of the whole bicycle frame is completed.Type: GrantFiled: December 18, 1992Date of Patent: December 21, 1993Assignee: Industrial Technology Research InstituteInventors: Jong-Pyng Chen, Jen-Loong Hwang, Ruey-Guang Jang, Sheng-Long Wu, Rong-Ho Yu

Patent number: 5219124Abstract: Apparatus and method for winding for winding enamel wires into a motor stator which provides for precisely positioning motor stators to be wound, so that the scraping of the outer coating of enamel wires by the wire slots of motor stators can be avoided during winding operation of motor stators. Furthermore, the improved multi-phase synchronous winding apparatus for motor stators is capable of immediately detecting the damage of the outer coating of the enamel wires during winding operation of motor stators so as to avoid the waste of enamel wires and working times. The improved multi-phase synchronous winding apparatus for motor stators also prevents the enamel wires from disengaging by the use of a tension control device during winding operations of motor stators.Type: GrantFiled: December 3, 1990Date of Patent: June 15, 1993Assignee: Industrial Technology Research InstituteInventors: Kwo-Yuan Shi, Ji-An Peng, Sheng-Long Wu, Yu-Kwang Chang
