Abstract: A rotating electrical machine includes a stator, a rotor with a permanent magnet, a first number of one or more first coils, and a second number of one or more second coils. The second number is different from the first number. The one or more first coils are disposed on the stator. The one or more second coils are disposed on the rotor. The one or more first coils and the one or more second coils are disposed on the stator and the rotor, respectively, in such a manner as to closely oppose each other in a state where the rotor is at a predetermined rotation angle position. The one or more first coils are arranged to induce a voltage in response to a relative position with respect to the one or more second coils.

Abstract: Disclosed herein is an antenna device that includes a first coil pattern having at least first, second, and third turns. As viewed in a coil axis direction, each of the first, second, and third turns has an opening with a width larger in a first direction than in a second direction orthogonal to the first direction. The width of the opening of the second turn in the second direction is larger than a width of the opening of the first turn in the second direction. The width of the opening of the third turn in the second direction is larger than the width of the opening of the second turn in the second direction and smaller than a width of the opening of the first turn in the first direction.

Abstract: Disclosed herein is a noise suppression sheet that includes a substrate having a first through hole, and a conductor pattern provided on one surface of the substrate. The conductor pattern has a plurality of linear patterns extending in a first direction and a connection pattern connecting the plurality of linear patterns. The one surface of the substrate has a clearance area surrounded by the plurality of linear patterns and having no conductor pattern. The size of the clearance area in a second direction different from the first direction is larger than an arrangement pitch between the plurality of linear patterns in the second direction. The first through hole is formed in the clearance area.
