20120064656 | METHOD FOR FABRICATING THERMO-ELECTRIC GENERATOR - For the present invention, a P-type thermo-electric thin-film layer and a N-type thermo-electric thin-film layer are respectively deposited on two sides of an insulating substrate. During the deposition, the P-type thermo-electric thin-film layer and the N-type thermo-electric thin-film layer are deposited and connected on the same exposed side of the insulating substrate, and then a PN junction is formed. This method makes the fabrication simplified without special process for connecting the P-type thermo-electric thin-film layer and the N-type thermo-electric thin-film layer. Due to the features of thin-film thermo-electric material, the performance of thermo-electric generator is improved. During the deposition, the P-type thermo-electric thin-film layer and the N-type thermo-electric thin-film layer are deposited and connected on the exposed side of the insulating substrate, so welding is not required in this heating surface side. The performance of thermo-electric generator fabricated in heating surface working temperature is accordingly greatly improved. | 03-15-2012 |

20130091997 | PUNCH DEVICE - A punch device includes a mounting platform, a punch mechanism, a feeding mechanism, and a positioning and ejecting mechanism. The punch mechanism is mounted over the mounting platform for punching a pre-punched workpiece positioned on the mounting platform. The feeding mechanism is mounted on the mounting platform for conveying the pre-punched workpiece. The positioning and ejecting mechanism is mounted on the mounting platform and positioned under the punch mechanism, for positioning the pre-punched workpiece during a punching process, and ejecting the punched workpiece after the punching process is performed, thereby facilitating an operator to take away the punched workpiece. | 04-18-2013 |
