Abstract: In order to radiate microwaves from a waveguide tube to a whole area from end to end of a radiation area within a heating chamber, and to heat uniformly an object to be heated without using a driving mechanism, a microwave heating device of the present invention includes openings for radiating the microwave from the waveguide tube to the inside of the heating chamber. The heating chamber includes a radiation area which has a length of approximate twice an in-tube wavelength in a propagation direction of the waveguide tube. Also, the openings are arranged to have an interval of approximate the in-tube wavelength in the propagation direction of the waveguide tube, and are symmetrically arranged to a center line which intersects perpendicularly to the propagation direction in the radiation area.

Abstract: A directional coupler according to the invention includes an opening in a wall surface of a waveguide, and a coupling line on an outer side of the waveguide. The opening is configured to not cross a tube axis of the waveguide in plan view, and to emit a circularly polarized wave. The coupling line includes first and second transmission lines and output parts disposed at both ends, the first and second transmission lines extending across the opening to cross the tube axis in plan view and being opposed to each other across the center of the opening. The first and second transmission lines are interconnected at a position displaced from an area vertically above the opening.

Abstract: A coil for a non-contact power transmission system according to the present disclosure is used in a non-contact power transmission system to transmit electric power via a non-contact method. The coil includes a first coil in which a wire is wound around at a center of a core; and a second coil placed at an end of the core, and wound with the wire. Winding axes of the first and second coils are oriented in different directions.

Abstract: The present disclosure provides a non-contact charging apparatus including a power transmitting coil and a power receiving coil which face each other. At least one of the power transmitting coil or the power receiving coil includes a magnetic body and a coil wound around the magnetic body. The magnetic body has, on both end portions, exposed regions in which the wound coil is absent. One of the exposed regions that is on a face facing the power transmitting coil or the power receiving coil is larger than another one of the exposed regions that is on a face not facing the power transmitting coil or the power receiving coil.

Abstract: A non-contact charger aims to control transmitted power efficiently. The non-contact charger includes a transmitting coil, an inverter circuit, a receiving coil, and a transmitted power control circuit. The inverter circuit outputs the transmitted power to the transmitting coil. The receiving coil receives power as received power from the transmitting coil. The transmitted power control circuit drives the inverter circuit at a frequency higher than maximum received power frequencies at which the received power has one or two maximum values.
