20120154100 | COIL AND METHOD FOR FORMING A COIL - A reactor coil includes first and second coil elements each formed by edgewise and rectangular winding of one piece of rectangular wire rod in a manner in which the wound rectangular wire rod is stacked rectangularly and cylindrically and, at a winding terminating end point of the first coil element, the rectangular wire rod is bent approximately 90 degrees in a direction opposite to the winding direction of the first coil element so that the rectangular wire rod is stacked in a direction opposite to the stacking direction of the first coil element and is wound edgewisely and rectangularly in a direction opposite to the winding direction of the first coil element to form the second coil element and, as a result, the first coil element and second coil element are aligned in parallel to each other in a continuous state. | 06-21-2012 |
20120032771 | Coil and method of forming the coil - A coil formed by winding one flat type wire material rectangularly edgewise thereby stacking the rectangularly edgewise wound flat type wire in rectangular tube shape, wherein not only one edge of the coil including the flat type wire including an end portion of start-of-winding thereof but also another edge of the coil including the flat type wire including an end portion of finish-of-winding thereof are formed to be projecting from an outer circumference of the coil. | 02-09-2012 |
20100219228 | REFLOW APPARATUS - The present invention provides a reflow apparatus capable of precisely adjusting the heating temperature and heating time when heating a work for reflow. A work transfer conveyor for transferring a work into a furnace body is disposed, wherein a plurality of preheating zones through for preheating the work, a plurality of reflow zones for heating the work for reflow, and a plurality of cooling zones for cooling the work are successively arranged along the work transfer conveyor in the furnace body. The individual reflow zones are formed shorter than the individual preheating zones in the work transfer direction. It is preferable that the sizes of the individual reflow zones in the transfer direction are shortened to approximately 65% to 85% with respect to the individual preheating zones or the conventional individual reflow zones. | 09-02-2010 |
20090206145 | REFLOW SYSTEM - A reflow system in which a reflow furnace is sequentially divided into a plurality of zones along a conveying path of a heat target which is conveyed and by controlling temperatures of the plurality of zones, the heat target which is conveyed is reflowed has: a cooling and flux collecting apparatus circulating and cooling atmosphere gases in furnace bodies of a part or all of the plurality of zones and collecting a flux; and a flow rate control unit which is inserted into a circulating path of the atmosphere gas of each of the zones and can control a flow rate. When the temperature of the zone is reduced, by controlling the flow rate control unit, the flow rate is set to be higher than that upon collecting the flux. | 08-20-2009 |
