Abstract: The communication system includes a first communication device, a second communication device, and a third communication device. The first communication device outputs a high frequency alternating current power, and a power receiving circuit of the second communication device receives the high frequency alternating current power via a second antenna. A power line is connected between the second antenna and the power receiving circuit. A first power line has a first semicircle portion and a second power line has a second semicircle portion. The first and second semicircle portions are combined together to provide a loop-shaped antenna. The third communication device receives the high frequency alternating current power output from the loop-shaped antenna. At least two of the first, second, or third communication devices transmit or receive communication signals using respective antennas. The first and second power lines are twisted with each other at a portion other than the loop-shaped antenna.

Abstract: A vehicle air conditioner includes a casing, a heater core that heats an air flow by heat exchange between the air flow and a heat medium, an electric heater that heats an air flow by an electric power, and a determiner that determines whether a temperature of the heat medium is equal to or lower than a predetermined temperature. When the determiner determines that the temperature of the heat medium is equal to or lower than the predetermined temperature, an air flow introduced into a casing is heated by the electric heater and flows toward the vehicle interior without passing through the heater core.

Abstract: A humidification device includes: an adsorber having an adsorbent that adsorbs and desorbs moisture; an adsorption case that forms an accommodating space to accommodate the adsorber; a first introduction portion that introduces cooled air produced by a cooling portion into the adsorption case; a second introduction portion that introduces heated air produced by the heating portion into the adsorption case; and a humidification-side guiding portion that guides humidification air humidified by the moisture desorbed within the adsorption case, to the vehicle interior. The first introduction portion is connected to a bottom surface portion of the air-conditioning case on the air-flow downstream side of the cooling portion in the air-conditioning case.

Abstract: A humidification device is used in a vehicle air conditioner having a cooler disposed in an air conditioning case. The air conditioning case has a ventilation path leading air into a vehicle compartment. The humidification device has an adsorber that absorbs and desorbs moisture, a blower, a door that opens or closes an air flow path, and a controller. The controller switches the air flow path by controlling the door to set (i) a dehumidification mode in which air cooled by the cooler is led to the adsorber, and moisture in the air is adsorbed by the adsorber or (ii) a humidification mode in which air is led to the adsorber, the moisture is moved from the adsorber to the air to humidify the air, and the humidified air is blown toward an occupant.

Abstract: In an electric motor, a magnetic bearing generates an electromagnetic force between multiple permanent magnets and a coil and rotatably supports an other side of a rotation shaft in an axis line direction. The rotation shaft is configured to be capable of being inclined with a rotation center line using a bearing side of the rotation shaft as a fulcrum. An electronic control device controls a current that flows to the coil such that an axis line of the rotation shaft approaches the rotation center line due to a supporting force which is the electromagnetic force between the multiple permanent magnets and the coil. Accordingly, the rotation shaft is rotatably supported to be freely rotatable by a magnetic bearing and the bearing.

Abstract: A heat transfer device couples a heat generation member with a heat radiation member, and transfers heat from the heat generation member to the heat radiation member. The heat transfer device includes a composite member and a heat conductor. The composite member includes multiple carbon nanotubes and multiple carbon fibers which are mixed into a base material and complexed together, and the respective carbon fibers are crosslinked with each other by the carbon nanotubes. The heat conductor has one flexible end embedded in the composite member. The embedded one end is crosslinked with the carbon fibers in the composite member through the carbon nanotubes.

Abstract: Multiple projections are provided at a flow-change portion, which corresponds to such a portion of a wall surface of an A/C casing, at which velocity gradient of air current becomes larger in an area adjacent to the wall surface, in order to decrease aerodynamic sound generated by disturbed air current.
