    Abstract: The vapor chamber includes a casing, a working fluid, a microchannel, and a wick. The casing includes an upper casing sheet and a lower casing sheet that face each other and are joined together at an outer edge so as to define an internal space therebetween. The working fluid is sealed in the internal space. The microchannel is in the lower casing sheet and in communication with the internal space so as to form a flow path for the working fluid. The wick is in the internal space of the casing, and is in contact with the microchannel. An area of the wick is larger than an area of a region corresponding to the microchannel in a plan view of the vapor chamber.

    Abstract: A display device includes a housing, an operation surface, a position sensor, a press sensor, and a display unit. The position sensor detects a touched position on the operation surface. The press sensor detects a press on the operation surface. The display unit displays an image. When the press sensor detects a pressing amount not smaller than a first threshold, a control unit sets, as a rotation axis of a three-dimensional image, a direction orthogonal to the sliding direction of the touched position detected in the position sensor. The control unit then rotates the three-dimensional image in accordance with the sliding direction of the touched position detected in the position sensor.

    Abstract: An antenna of a communication terminal is disposed on a side on which a bottom surface of a reflective plate, which is included in a display, is present. When the reflective plate is irradiated by an LED light source, the antenna cannot be seen from the side on which a display screen of the display is disposed. Accordingly, an antenna coil of the antenna does not need transparent electrodes and can be made of various materials each having a high conductivity. Therefore, the antenna has high sensitivity, low manufacturing cost, and very efficiently performs near field communication with an external device located on the display screen side of the display.

    Abstract: To ensure a sufficient communication distance and to concurrently suppress a conductor loss, a coil antenna includes a magnetic core including a first peripheral surface including at least a first principal surface, a first coil conductor located on the first principal surface and wound around a predetermined winding axis, a first base material layer stacked on the first principal surface, including at least a first surface parallel or substantially parallel to the first principal surface, and made of a material having a lower magnetic permeability than the magnetic core, and a second coil conductor located on at least the first surface. Opposite ends of the second coil conductor are coupled to the first coil conductor on the first principal surface, and a direction in which a current flows through the first coil conductor on the first principal surface is substantially the same as a direction in which a current flows through the second coil conductor on the first surface.
