A portable telephone 1 has an image stabilization system 10 for driving an image pickup unit 9 by a pair of driving members 15a and 15b functioning as actuators, thereby performing image stabilization. Driving members 15a and 15b are formed as a wire of shape memory alloy (SMA) and when a voltage is applied to both ends and a current is supplied, driving force is generated in the contraction direction. With respect to the wire diameter of the SMAs, the wire diameter of the SMAs is set between 10 μm and 80 μm, thus the mountability and response are improved appropriately.

摘要： Provided is a transmission circuit 1 which is capable of precisely compensating for an offset characteristic of an amplitude modulation section 15, and operating with low distortion and high efficiency over a wide output electric power range. A signal generation section 11 outputs an amplitude signal and an angle modulation signal. An amplitude amplifying section 14 inputs, to the amplitude modulation section 15, a signal corresponding to a magnitude of the amplitude signal having been inputted. The amplitude modulation section 15 amplitude-modulates the angle modulation signal with the signal inputted from the amplitude amplifying section 14, and outputs a resultant signal as a modulation signal. The power measuring section 18 measures an output power of the amplitude modulation section 15. An offset compensation section 12 reads an offset compensation value from a memory 13 in accordance with the output power of the amplitude modulation section 15, and adds the read offset compensation value to the amplitude signal.
