Abstract: A wireless power supply apparatus using magnetic resonance is provided for a linear motion type robot. In the apparatus, a high-frequency signal for foreign matter detection is generated. This signal is different in wavelength and frequency from a high-frequency signal for transmitting power between a power transmission coil and a power reception coil. The wavelength is wavelength λ and the frequency is frequency f. The power transmission coil serves as an apparent antenna of which the long side is set to λ/2. At least either of a wavelength λx or a resonance frequency fx of a resonance wave attributed to the resonance in the antenna is detected when the high-frequency signal is supplied to the antenna. Whether or not foreign matter is present on the power transmission coil is detected based on the wavelength λx or the resonance frequency fx.

Abstract: In a wireless power supply apparatus, a first unit electrically connected to a power supply and a second unit electrically connected to an electric load. Power transmission is performed wirelessly between the first and second units using a magnetic resonance phenomenon. Each of the units has a resonant amplifier circuit provided with switching means driven by a drive signal, a resonant coil to which a high-frequency signal generated by the resonant amplifier circuit is supplied such that the resonant coil functions as a resonant inductor on the resonant amplifier circuit, and electric storage means electrically connected to the resonant amplifier circuit so as to be capable of charging and discharging power. The second unit includes current detecting means for detecting a current flowing through the storage means, and phase control means for controlling a phase of the drive signal for the switching means based on the detected current.

Abstract: A thermal conductive mechanism for a battery pack made up of a stack of a plurality of sub-battery modules each of which includes a plurality of battery cells arrayed thereon. The sub-battery modules each has opposed major surfaces and are laid to overlap each other in a direction perpendicular to the major surfaces. The thermal conductive mechanism is equipped with plates provided one for each of the sub-battery modules. Each of the plates has a given number of the battery cells disposed thereon and also has heat transfer surfaces extending in a planar direction of the plate. The heat transfer surfaces are placed in one of direct and indirect contact with the given number of the battery cells to achieve transfer of heat therebetween, thereby equalizing the temperature in each of the battery cells and also minimizing a difference in temperature among the battery cells.
