20150310961 | INSULATING COATED WIRE AND METHOD FOR MANUFACTURING THE SAME - An insulating coated wire includes a center conductor and an insulating coating. The insulating coating has a bending auxiliary section in which the thickness of the insulating coating is smaller than that of the other portion, and that has a shape in which at least a part thereof protrudes outward in the radial direction. The bending auxiliary section has a shape that facilitates bending of the insulating coated wire by elongation deformation thereof. This insulating coated wire can be manufactured by arranging, on the circumference of an insulating coated wire material, a metal mold that has the inner surface including the section having a shape protruding outward in the radial direction, and forming the bending auxiliary section in the shape along the inner surface of the metal mold by heating the insulating coating within the metal mold and generating a pressure difference between inside and outside of the insulating coating. | 10-29-2015 |

20100142228 | Bi-Directional DC-DC Converter and Control Method - A bi-directional DC-DC converter uses a transformer for both step-down and step-up operations. A switching frequency for operating a switching device is set separately for the step-down and step-up operations. When, for example, the switching frequency during the step-up operation is lower than the switching frequency during the step-down operation, the range in which the duty ratio in PWM control can be controlled is widened, compensating for step-up ratio insufficiency. Conversely, step-down ratio insufficiency is compensated for by making the switching frequency during the step-down operation lower than the switching frequency during the step-up operation. | 06-10-2010 |
