Patent number: 8736412Abstract: A magnetic element may include a first core member, a second core member facing the first core member along an entire outer periphery thereof, a coil, and a base shaped body on which the first core member and the second core member are placed. The base shaped body is provided with a base member and a terminal member, and the terminal member is provided with a binding terminal part, which projects outward in a first corner part of the base member and projects from the base member on a side lower than a portion of a winding frame part side of one flange part. The second core member is provided with a cutout part at a portion corresponding to the first corner part of the base member for allowing insertion of an end drawn out from the winding frame part in a state of not contacting the second core member.Type: GrantFiled: November 9, 2011Date of Patent: May 27, 2014Assignee: Sumida CorporationInventors: Tatsumi Nishino, Masahiko Ono

Patent number: 7755558Abstract: The size of an antenna coil is reduced, and it is possible to prevent a lowering of the reception sensitivity due to a difference of the arrangement position of the antenna coil. On a winding frame of a ferrite core, a first coil and a second coil are wound in such a manner that their winding axes orthogonally intersect each other. A third coil is wound around an outer circumference of the first coil and the second coil in such a manner that the third coil's winding axis orthogonally intersects the winding axes of the first coil and the second coil.Type: GrantFiled: April 18, 2007Date of Patent: July 13, 2010Assignee: Denso CorporationInventors: Hozumi Ueda, Tatsumi Nishino, Takahide Kitahara
