Patent number: 10446316Abstract: A coil device includes a first coil portion which faces a second coil portion of another coil device and has a conductive wire, and at least one non-magnetic member disposed on an opposite side from a side facing the second coil portion. The non-magnetic member includes an eddy current interrupter for changing a state of an eddy current formed in the non-magnetic member by interrupting a portion of the eddy current.Type: GrantFiled: December 22, 2016Date of Patent: October 15, 2019Assignee: IHI CORPORATIONInventors: Kentarou Furiya, Susumu Tokura, Masakazu Hara, Jun Araki

Patent number: 10315527Abstract: A power reception coil device is a power reception coil device attached to a movable body, for wirelessly receiving power from a power transmission coil device, and includes a power reception coil portion including a conductive wire, and a nonmagnetic body disposed between the movable body and the power reception coil portion. The nonmagnetic body includes a first overhang protruding in a first direction outwardly from one end portion of a region onto which the power reception coil portion is projected in a second direction. The first direction is orthogonal to the second direction in which the power reception coil device opposes the power transmission coil device. The first overhang is longer than or equal to a maximum permissible misalignment permissible between the power reception coil portion and a power transmission coil portion of the power transmission coil device.Type: GrantFiled: February 16, 2017Date of Patent: June 11, 2019Assignee: IHI CORPORATIONInventors: Susumu Tokura, Masakazu Hara, Kentarou Furiya, Jun Araki
