| 20110013431 | SWITCHING POWER CONVERSION CIRCUIT AND POWER SYPPLY USING SAME - A switching power conversion circuit receives an input voltage and generates an output voltage to a system circuit. The switching power conversion circuit includes a power circuit, a feedback circuit, a control circuit, and an initiation circuit. The power circuit includes a first switch circuit. The feedback circuit generates a feedback signal according to a power-status signal and the output voltage. The first switching circuit is conducted or shut off according to the feedback signal under control of the control circuit, so that the input voltage is converted into the output voltage and the first auxiliary voltage by the power circuit. If the power-status signal is in an off status, a ratio of the feedback signal to the output voltage is equal to a first feedback ratio and the magnitude of the first auxiliary voltage is lower than a normal operating voltage value, so that the control circuit is disabled. | 01-20-2011 |
| 20110148395 | OVER-VOLTAGE AND OVER-TEMPERATURE DETECTING CIRCUIT - An over-voltage and over-temperature detecting circuit includes a voltage-limiting circuit, a temperature sensing circuit, a current source, a first comparing circuit and a second comparing circuit. The equivalent resistance of the temperature sensing circuit varies with the temperature. The current source provides a first current to a detecting terminal, so that a detecting voltage is generated at the detecting terminal. By comparing the magnitude of the detecting voltage with the first reference voltage value, the first comparing circuit generates a corresponding temperature status signal. By comparing the magnitude of the detecting voltage with the second reference voltage value, the second comparing circuit generates a corresponding voltage status signal. If the temperature exceeds the temperature upper limit, the temperature status signal is in an enabling status. If the first voltage exceeds the voltage upper limit, the voltage status signal is in an enabling status. | 06-23-2011 |

| 20080207053 | USB connector housing - A USB connector housing includes: a hollow main body; a guiding pin extending from the main body; and an engaging member extending from the main body and including a pair of opposite engaging pins adapted to extend through an engaging hole in a board. Each of the engaging pins has a leg portion extending from the main body, a body portion extending from the leg portion and adapted to abut against a hole defining wall of the engaging hole in the board, a neck portion extending from the body portion, and a head portion enlarged in cross-section from the neck portion. The head portion of each of the engaging pins has an anchor end adapted for anchoring at a periphery of the engaging hole in the board. The anchor end of the head portion has a width greater than those of the neck portion and the body portion. | 08-28-2008 |
