| 20110277277 | Fastener for heat sink - A fastener for fastening a heat sink and a heat-generating element includes a bended flexible main body, an upper hook portion, and a lower hook portion. The heat sink includes a plurality of fins. The upper hook portion extends from an upper end of the main body for matching the fins and hooking the heat sink. The lower hook portion extends from a lower end of the main body for hooking the heat-generating element. | 11-17-2011 |
| 20110248027 | Heating coil - A heating coil includes at least one winding having a plurality of approach portions. Each of the approach portions is close to a workpiece surrounded by the winding. The winding defines two electrodes at two ends thereof for electric connection with a high-frequency power source. Accordingly, the workpiece can be heated more equably than that of the prior art. | 10-13-2011 |
| 20110059633 | Surface mount contact - A surface mount contact includes a conducting pin having a shank, a first end at one end of the shank and second end at the other end of the shank, a first annular flange extending around the periphery of the shank and spaced between the first end and the second end and a second annular flange extending around the periphery of the shank and spaced between the second end and the first annular flange, and a thermoplastic connection member joined to the second end of the conducting pin and spaced from the second annular flange at a predetermined distance so that there is a room for the user to judge the connection status and quality between the conducting pin and the thermoplastic connection member during surface mounting, assuring bonding stability. | 03-10-2011 |
| 20110044075 | POWER CONVERTER CAPABLE OF LOWERING POWER WASTAGE ON STANDBY - A power converter includes at least one electric control switch, an electric current detecting and converting unit, a power controller, and a voltage detecting and controlling unit at the primary side; and a synchronous rectifying circuit, two MOSFETs, and an oscillating loop. During the actual operation, electric current detecting and converting unit outputs an AC voltage signal to the power controller and outputs a DC voltage signal to the voltage detecting and controlling unit, and then voltage detecting and controlling unit compares with a reference voltage to turn off the synchronous rectifying circuit at the no-load mode and to rectify via a body diodes of the MOSFETs. Accordingly, the power converter can reduce the power wastage at the no-load mode to be energy-saving. | 02-24-2011 |
| 20090135634 | Synchronous rectifier drive circuit - A synchronous rectifier drive circuit includes a primary side and a secondary side. The primary side has a first coil winding, a first MOSFET, an auxiliary MOSFET, an auxiliary capacitor, and an input power source. The secondary side has a second coil winding, a DC voltage source, a second MOSFET, a third MOSFET, a fourth MOSFET, a fifth MOSFET, and an inductor. The gate of the second MOSFET is connected with the source of the fourth MOSFET. The gate of the third MOSFET is connected with the source of the fifth MOSFET. The inductor has two ends, one of which is connected with the drain of the third MOSFET. Accordingly, the synchronous rectifier drive circuit can lessen the variation of pulse wave of the drive voltage and refrain the surge voltage to protect the electronic elements. | 05-28-2009 |
