20090066457 | ELECTRONIC DEVICE HAVING TRANSFORMER - An electronic device includes a first inductor which is symmetrical with respect to a first line in plan view and a second inductor having the same shape as that of the first inductor. The first inductor and the second inductor are disposed so as to be symmetrical with each other with respect to a second line which is orthogonal to the first line. The first inductor and the second inductor are disposed so as to intersect on the second line in plan view. | 03-12-2009 |
20090167475 | Winding Method and Coil Unit - A rectangular coil unit is manufactured in such a manner that two wires are simultaneously regularly wound on four outer surfaces of a bobbin having a rectangular section so that the wires advance obliquely together for a lane change corresponding to 0.5 wire on one (a lower surface side) of a pair of parallel surfaces of the four outer surfaces of the bobbin and for a lane change corresponding to 1.5 wires on the other one (an upper surface side) of the parallel surfaces. | 07-02-2009 |
20110267164 | Inductor Structure - An inductor structure comprising: a first loop and a second loop; a first feed line connected to a first end of the first loop and a second feed line connected to a first end of the second loop, each of the first and second feed lines extending through an area circumscribed by one of the first and second loops; and a crossover section adjacent to the first end of the first loop and the first end of the second loop, the crossover section coupling the first loop to the second loop so as to cause current flowing from the first feed line to the second feed line to circulate around the first loop in a first rotational direction and around the second loop in a second rotational direction opposite to the first rotational direction. | 11-03-2011 |
20120025940 | COIL - A coil is formed by coaxially winding a second winding so as to be in intimate contact with an outer circumferential portion of a first winding wound about a winding shaft axis. In the first winding, one side of a winding wire is wound from an inner circumferential side to an outer circumferential side, the other side of the winding wire is drawn forth from the inner circumferential side to the outer circumferential side, while crossing the one side of the winding wire, and a thickness in a direction of the winding shaft axis in crossing portions of the one side of the winding wire and the other side of the winding wire is equal to a thickness in other portions. | 02-02-2012 |
20130021130 | ARRANGEMENT HAVING AT LEAST TWO COILS WHICH ARE ARRANGED AXIALLY ONE ABOVE THE OTHER ON A COMMON CORE LIMB - An exemplary arrangement includes blocks arranged between the inner winding, the individual barriers and the outer winding in order to maintain defined spacing's along the circumference. At least two coils are arranged axially one above the other on a common core limb. Each coil has at least two windings arranged radially one above the other and barriers are provided between the windings. The barriers of adjacent coils are radially offset with respect to one another, and the edge regions of the barriers engage one another in a comb-like manner. | 01-24-2013 |
