20130162384 | DEVICE AND MANUFACTURING METHOD FOR A DIRECT CURRENT FILTER INDUCTOR - The device and manufacturing method for a Direct Current (DC) filter inductor are disclosed. The device comprises a magnetic core, at least one first winding and at least one second winding. The magnetic core has at least one air gap. The first winding and the second winding are connected to each other in parallel that having a mutual inductance, and are wrapped around the magnetic core respectively. A difference between a first inductance of the first winding and the mutual inductance is smaller than a difference between a second inductance of the second winding and the mutual inductance. A Direct Current (DC) resistance of the first winding is larger than a DC resistance of the second winding. The first winding is closer to the air gap compared to the second winding. | 06-27-2013 |
20130153193 | BIDIRECTIONAL HEAT SINK FOR PACKAGE ELEMENT AND METHOD FOR ASSEMBLING THE SAME - In a bidirectional heat sink for a package element and a method for assembling the same, the bidirectional heat sink includes a first heat-dissipating plate, a second heat-dissipating plate, and a plurality of heat-dissipating pieces. The first heat-dissipating plate is provided with a groove. Both sides of the groove are formed with two separation walls. The package element is inserted into the groove to contact the two separation walls. The second heat-dissipating plate extends from one end of the first heat-dissipating plate. Each of the heat-dissipating pieces extends from the second heat-dissipating plate in a direction away from the first heat-dissipating plat). By this structure, the contact area of the package element is increased to improve the heat-dissipating efficiency. Further, the assembling process is performed quickly to form a firm structure. | 06-20-2013 |
