Patent number: 8217745Abstract: An inductor includes a base and a winding assembly. The base includes an outer frame, a middle part and a connecting part. The outer frame has a first upper surface. The middle part has a second upper surface. The connecting part is connected with the outer frame and the middle part and has a third upper surface. The connecting part, the outer frame and the middle part collectively define a receptacle. The winding assembly is accommodated within the receptacle. The second upper surface of the middle part is disposed at a higher level with respect to the first upper surface of the outer frame. A first height is defined by the level difference between the second upper surface and the third upper surface. A second height of the winding assembly is smaller than the first height, so that a fourth upper surface of the winding assembly is disposed at a lower level with respect to the second upper surface after the winding assembly is accommodated within the receptacle.Type: GrantFiled: July 28, 2010Date of Patent: July 10, 2012Assignee: Delta Electronics, Inc.Inventors: Ching-Hsiang Tien, Yu-Chin Chen, Ming-Cheng Li, Zhi-Liang Zhang

Patent number: 7623770Abstract: A fan control system includes a power source, a switch control circuit, a switch control signal delivering unit and a fan circuit module. The power source outputs a nominal power, the switch control circuit electrically connects to the power source, the switch control signal delivering unit electrically connects to the switch control circuit and can send a power control signal to the switch control circuit, and the fan circuit module electrically connects to the switch control circuits. In an initial operation state, the nominal power output from the power source can be reduced to a control power sending to the fan circuit module via the switch control circuit to drive at least one fan within the fan circuit module, and then the power control signal controls the control power after the switch control signal delivering unit sends the power control signal to the switch control circuit.Type: GrantFiled: June 4, 2007Date of Patent: November 24, 2009Assignee: Asustek Computer Inc.Inventors: Sheng-Hsiung Chang, Chi-Chun Chen, Yu-Chin Chen
