| 20120044661 | CAPACITOR HOLDER - A holder for mounting multiple capacitors onto a circuit board includes a main structure and a plurality of latching member. The main structure has a top plate and a plurality of side plates. The top plate includes a plurality of holding slots, with the latching members off the side plates. Each latching member has an extension portion and an engaging member. The engaging member is located at the end of the extension under the bottom edge of the side plate. The capacitor includes a main body and a pair of electric leads at one end of the main body. At the opposite end of the electric leads, the main body is bounded on top by the top plate of the main structure, where the main body of each capacitor emerges partially above the upper surface of the top plate. | 02-23-2012 |
| 20120026698 | INTEGRATED CIRCUIT BOARD - An integrated circuit board includes a bridging filtering capacitor, a bypass capacitor, a thermistor, and a varistor. The integrated circuit board further includes an electrolytic capacitor set having a plurality of electrolytic capacitors, which are arranged in parallel and adjacent to each other, and a mounting frame for grouping the electrolytic capacitors. The present invention uses the above elements to reduce the vertical height, the horizontal width, and the occupied area. Therefore, the overall dimension of the circuit board can be reduced to make the electronic devices smaller, especially for thin electronic devices such as LCD TVs and screens. | 02-02-2012 |
| 20120020132 | POWER CONVERSION SYSTEM WITH ZERO-VOLTAGE START-UP MECHANISM, AND ZERO-VOLTAGE START-UP DEVICE - A power conversion system with zero-voltage start-up mechanism and a zero-voltage start-up device are disclosed. The system includes a power conversion circuit, a power factor correction unit, a storage capacitor, a storage switching unit, and a zero-voltage detection module. The storage switching unit is serially connected with the storage capacitor, and particularly controlled by the zero-voltage detection module. The zero-voltage detection module detects a timing as an input voltage is at low level, and then outputs a control signal to turn on the storage switching unit. Therefore, the present invention assures that the power conversion system is turned on when the input voltage is at the low level, in order to suppress the system from a surge current. | 01-26-2012 |
| 20120020131 | POWER APPARATUS AND METHOD OF SUPPLYING POWER - The present invention provides a power apparatus, which includes a switch unit, a bleeder resistor, a filter, a rectifier, a power factor corrector, an output capacitor, a rectifying diode, a surge absorber, a main power supply, and a standby power supply. Moreover, the AC power charges to the output capacitor by means of the rectifying diode and the surge arrester, such that the standby power supply generates a standby power while the switch unit is off. Furthermore, the AC power charges to the output capacitor through the switch unit, the bleeder resistor, the filter, the rectifier and the power factor corrector, such that the main power supply generates a main power while the switch unit is on. The present invention further provides a method of supplying power. | 01-26-2012 |
| 20120019985 | ALUMINUM ELECTROLYTE CAPACITOR - An aluminum electrolytic capacitor includes a main body, two electric leads, and a metal set plate. The main body has a base and a plastic insulating film. The electric leads are located at one end of the base. The metal set plate is located at opposite end, with a connecting portion and a soldering portion. The connecting portion is located at the surface of the other end of the base opposite of the two electric leads. The soldering portion extends outside of the main body. The plastic insulating film wraps around the main body and the outer edge of the connecting portion. Thereby, the metal set plate is secured firmly with the main body. The soldering portion of the metal set plate is soldered onto the printed circuit board, allowing the aluminum electrolytic capacitor to be firmly attached to the printed circuit board. | 01-26-2012 |
| 20120013479 | LED SYSTEM AND DRIVING DEVICE WITH ERROR DETECTION, AND ERROR DETECTION MODULE THEREOF - A LED system and driving device with error detection and an error detection module thereof is disclosed. In which, through the detection of the error detection module, the errors associated with the LED module and the driving circuit may be detected. If the errors are detected, the error detection module may output a determination signal to the control unit so that the LED system could be protected from damages. | 01-19-2012 |
| 20120013432 | THERMISTOR - A thermistor comprises a main body, two electric plugs, a metallic fixing piece, and a cover. The electric plugs are located on one end of the main body, and the metallic fixing piece is located on the side of the main body. The metallic fixing piece has a connecting portion up against one side of the main body, and a soldering portion located on the other end of the main body, opposite to the electric plugs and protruding from the main body. The cover is over the main body and the connecting portion of the metallic fixing piece, thereby securing the metallic fixing piece to the main body. The soldering portion of the metallic fixing piece can be soldered directly onto the printed circuit board, thereby anchoring the thermistor to the printed circuit board more securely. | 01-19-2012 |
