20150204913 | ELECTRIC CURRENT DETECTOR AND CORE COMPONENT USED THEREFOR - In an electric current detector according to the present invention, an annular core | 07-23-2015 |
20140184379 | COIL WINDING METHOD AND WINDING APPARATUS - The present invention is to provide a plurality of unit coil portions formed by winding one conductive wire about a winding axis is placed side by side in the winding axis direction, each of the unit coil portions is formed by unit wound portions having different inner circumferential lengths from each other, the unit coil portion is multi-layered in at least a part thereof by pushing at least a part of the unit wound portion having a small inner circumferential length inside the unit wound portion having a large inner circumferential length, and the unit wound portion is wound along a loop shape winding route having a plurality of arc shape corner parts. In unit wound portions forming the unit coil portion, corner parts formed at the same phase angle with respect to the winding axis are formed in an arc shape having curvature center at the same position. | 07-03-2014 |
20140028432 | AUTOMATIC WINDING MACHINE, AIR CORE COIL, AND WINDING METHOD OF THE SAME - An automatic winding machine has a rotation drive mechanism, four winding core shafts protruding from the drive mechanism and being rotated integrally with a rotation center of the drive mechanism, the winding core shafts whose axial centers are parallel to the rotation center, a reciprocating mechanism for reciprocating the winding core shafts, at least one pressing roller biased in the direction of bringing close to a rotation passage of the winding core shafts from the outer circumferential side, and a conductive wire supply mechanism for continuously supplying a conductive wire between the winding core shafts and the pressing roller. | 01-30-2014 |
20120299589 | ELECTRIC CURRENT DETECTOR AND CORE COMPONENT USED THEREFOR - In an electric current detector according to the present invention, an annular core | 11-29-2012 |
20100218366 | COIL DEVICE AND METHOD FOR MANUFACTURING SAME - A method for manufacturing a coil device comprises a first step of twisting a tip end part of the conductive wire by approximately 90 degrees with respect to a conductive wire portion arranged rearward continuously from the tip end part to form a twist part, and winding the tip end part of the conductive wire around the outer peripheral surface of the core in a lying posture on the outer peripheral surface; a second step of winding the conductive wire arranged rearward continuously from the twist part around the outer periphery surface of the core in a standing posture on the outer peripheral surface; and a third step of transforming the conductive wire on a tip end side with respect to the twist part in a direction apart from the outer periphery surface of the core to form one lead part extending substantially linearly. | 09-02-2010 |
