摘要： PROBLEM TO BE SOLVED: To solve the problem of a wireless charging stand for transmitting power non-contact to a portable device by using electromagnetic induction, that although a ferrite plate is disposed for a power transmission coil in order to improve power transmission efficiency and prevent magnetic flux leakage, the inductance value of the power transmission coil varies with a distance between the power transmission coil and the ferrite plate, so that as the distance between the power transmission coil and the ferrite plate varies, so does the resonance frequency of the wireless charging stand, resulting in a reduction in power transmission efficiency, requiring that the distance be maintained constant.SOLUTION: A wireless charging stand 10 has a circuit board 20, a power transmission coil 30, and a ferrite plate 40 accommodated inside a case, the power transmission coil 30 being fixed to the circuit board 20 and the ferrite plate 40 being fixed to the internal bottom face of the case and therefore disposed below the power transmission coil 30. Since the distance between the power transmission coil 30 and the ferrite plate 40 is thereby made to be constant, a reduction in power transmission efficiency caused by a variation in the resonance frequency of the wireless charging stand 10 can be restrained.

摘要： PROBLEM TO BE SOLVED: To provide a rotary SMA actuator extremely simply formed and easily handled such as switching between normal and reverse directions.
SOLUTION: Both ends of a shape memory alloy are connected and fixed to a voltage source. A connection point at the center of the shape memory alloy is mechanically and electrically connected to one end of a metal spring. The other end of the metal spring is connected and fixed to a ground. The connection point has a contact in contact with a rotor. When direct voltages equal to each other are applied to both ends of the shape memory alloy in an asynchronous way, the linear displacement of the shape memory alloy is changed to the rotating displacement at the connection point, the rotor is brought into contact with the contact, and the rotor is rotated. The linear displacement of the shape memory alloy is changed to the rotating displacement by a simple structure, and a stepping rotation at a very low speed is provided with a simple drive power supply.
