20110026278 | CURRENT-CONTROLLED SELF-OSCILLATING FLYBACK CONVERTER WITH TWO TRANSISTORS - A current controlled self-oscillating flyback converter with two transistors. The converter includes a soft start circuit, a MOS transistor, a transformer, a pulse frequency modulation circuit, a reference amplification circuit, an isolation optical coupler and a voltage-stabilized output circuit. The pulse frequency modulation circuit includes a transistor, a third resistor, a capacitor connected in parallel with the third resistor and a fourth resistor. The pulse frequency modulation circuit further includes a transistor current control circuit. The control circuit is connected between the MOS transistor and the transistor. | 02-03-2011 |
20080202795 | Method of Improving the Strength of a Spot-Welded Joint Between Fine Enameled Wire and Circuit Board - A method for improving the reliability of the welding spot between thin enameled wires and an electronic board and thus securing the connection therebetween, by pulling the terminals of the enameled wires to the back of the electronic board and thereby creating a bearing point on the structure of the board. The bearing point, positioned between the welding spot and the wire terminal, effectively prevents the external forces of stress from directly acting on the welding spot when the terminals of the wire are pulled, swung up and sown, or subjected to other external pulling forces. | 08-28-2008 |
