Abstract: An inductor coil includes a wire which is wound in alternating layers such that the surface area of the wire in each winding viewed from above or below the coil is substantially equal in each half of the coil defined by a line bisecting the center point in each layer. The layers are also wound in a serpentine fashion to balance the capacitance between layers. The substantially equal surface area of wire in each half of a coil layer and in adjacent coil layers results in a balanced capacitance of the coil which, in turn, results in reduced common mode noise.

Abstract: A non-contact power reception apparatus is provided, in which a power reception coil for a charging system and a loop antenna for an electronic settlement system are mounted on a battery pack and a cover case of a portable terminal such that the power reception coil is arranged in the center thereof and the loop antenna is disposed outside the power reception coil, so that a mode of receiving a wireless power signal and a mode of transmitting and receiving data are selectively performed, thereby preventing interference from harmonic components and enabling non-contact charging and electronic settlement using a single portable terminal. A jig for fabricating a core to be mounted to the non-contact power reception apparatus is provided.

Abstract: The invention provides a method and a device for producing a winding element from a supplied wire, in particular from a round copper wire, said method and device allowing the economical and flexible production of a winding element which, when subsequently used in the field of electrical engineering as a coil or inductor fitted in a stator, ensures the highest possible groove filling factor. For this purpose, the wire is wound to a three-dimensional shape and the cross section of the wire is changed simultaneously, as a result of which separate method steps and therefore tool arrangements for three-dimensional winding of the wire as well as the change of the cross-section of the wire can advantageously be dispensed with.

Abstract: A coil unit may include an even number of coils comprising a first coil and a second coil; and a coil holding member which holds the even number of the coils. An outer peripheral face of the coil holding member may include a side-face pair comprising a first side face and a second side face which are substantially parallel to each other. The first side face may be formed with a first protruded part around which the first coil is wound, the first protruded part being protruded to an outer peripheral side with respect to the coil holding member. The second side face may be formed with a second protruded part around which the second coil is wound, the second protruded part being protruded to an outer peripheral side with respect to the coil holding member. The first coil and the second coil may be structured from one conducting wire.

Abstract: Techniques and mechanisms for delivering power with a transformer. In an embodiment, the transformer comprises a dielectric slab structure, a first conductor, a layer of ferromagnetic material disposed around first windings of the first conductor, and a second conductor which forms second windings around the layer of ferromagnetic material. For one of the first windings or one of the second windings, a cross-section of the winding conforms to a rectangle, wherein a width of the cross-section which is more than a height of the cross-section. A ferromagnetic material of the ferrite layer extends between successive ones of the first windings. In another embodiment, a volume fraction of the ferromagnetic material in the ferrite layer is equal to or less than ninety seven percent (97%).
