20090027151 | Reactor Part - To reduce a reactor core shape so as to decrease an entire reactor size and to lower a cost while improving DC superimposition of a high current value. | 01-29-2009 |
20090144967 | Coil and Method for Forming Coil - [Problem] Manufacturing work of a coil is simplified and miniaturization of a reactor is achieved by reducing occupied space as much as possible. | 06-11-2009 |
20100226410 | Securing structure of sensor element having lead and securing unit thereof - A securing structure for securing a measuring member having a sensor element and a lead elongated from the sensor element to a subject to be measured, the securing structure includes the measuring member including a measuring section having a covered portion in which a part of the lead elongated from the sensor element and having a predetermined length is covered by a material having a rigidity larger than that of the lead, the covered portion being folded toward the side of the lead elongated from the covered portion to produce a folded end portion; and the subject to be measured having an insertion section through which the measuring section is inserted from the side of the folded end portion, a container section which contains the measuring section inserted through the insertion section, and a contact section with which the head portion of the covered portion comes into contact and by which the measuring section is prevented from falling out, when the lead is pulled. | 09-09-2010 |
20110169598 | Reactor part - A reactor part includes at least a winding and a magnetic substance core, in which the core includes a pair of winding portions around each the winding is wound, and a non-winding portion around which no winding is wound, wherein a cross-sectional area in a direction orthogonal to a magnetic path of the non-winding portion of the core is made smaller than a cross-sectional area in a direction orthogonal to a magnetic path of the each of winding portions. | 07-14-2011 |
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 |
20130106556 | REACTOR AND MANUFATURING METHOD THEREOF | 05-02-2013 |
20130241686 | REACTOR AND MANUFACTURING METHOD THEREOF - A reactor includes a coil and a core unit having partial cores butted against one another to form a closed magnetic path. The partial cores include a first partial core forming and a second partial core. The first partial core is inserted in the hollow of the coil. A pressed face of the first partial core is oriented orthogonal to the winding axis direction of the coil. The second partial core is butted against the first partial core. A pressed face of the second partial core is oriented orthogonal to a direction different from the winding axis direction. The pressed face of the second partial core is a substantially flat plane. | 09-19-2013 |
20140217642 | REACTOR AND MANUFACTURING METHOD THEREOF - Divided cores | 08-07-2014 |
20140292456 | REACTOR - A reactor includes an annular core, coils, a sensor detecting a state of the reactor, and a connector outputting signal from the sensor. Resin-molded bodies are provided around the annular core. The resin-molded body has bobbins for the respective coils and core covering portions formed integrally with each other. An exposed area where no resin covers the bottom of the core is formed in the lower face of the covering portions. A holder to fasten the connector is formed integrally with the upper portion of the covering portion. An assembly including the resin-molded bodies in which the annular core is embedded, and the coils wound around the bobbins are retained in a metal casing. A clearance is formed between the assembly and the casing, and a filler is filled in this clearance. The filler covers the exposed area of the core bottom. | 10-02-2014 |
20150035636 | RESIN-MOLD CORE AND REACTOR USING THE SAME - A resin-mold core includes right and left leg portions, and a yoke portion interconnecting those. The resin-mold core includes a magnetic core, and a mold component having the magnetic core embedded therein by molding. Openings where the magnetic core in the mold component is exposed are formed in multiple faces of the mold component that are upper, lower, front, rear, and right and left faces. Apart of the yoke portion of the resin-mold core corresponding to a location where terminals are drawn to the exterior of the core from coils attached to the outer circumferences of the leg portions of the core has no opening formed in the multiple faces of the mold component. Positioning members to coaxially align the leg portions of the opposing resin-mold core are formed in abutting faces of the leg portions of the resin-mold core. | 02-05-2015 |
