    摘要: Either linear operating mode or saturation operating mode is set as the operating mode of a high-frequency power amplifier on the basis of an operating mode set signal. The gain of a variable gain amplifier provided in front of the high-frequency power amplifier and values of output voltage and bias current supplied from a supply voltage/bias current control circuit to the high-frequency power amplifier are switched. The gain of the variable gain amplifier in the saturation operating mode is formed so as to be higher by a predetermined value than that in the linear operating mode. Accordingly, the high-frequency power amplifier operates in the designated operating mode, so that the output transmission power range can be widened.

    摘要: In an auto image stabilization system, a driving member formed as a wire of shape memory alloy (SMA) is retained by a projection of an image capturing unit. A distance Lb from the rotation center of an elastic deforming part to center of gravity (point of application) of the image capturing unit is longer than a distance La from the rotation center of the elastic deforming part to the projection (power point). In the configuration, equivalent mass (apparent mass) of the image capturing unit becomes (Lb/La) times, and it causes deterioration in response. Consequently, the driving member having an ellipse-shaped section in which a value obtained by dividing the width in the longer direction of the section by the width in the shorter direction is 1.3 or larger is employed. As a result, heat dissipation of the driving member increases, so that response in the SMA actuator can be properly improved.

    摘要: An art of a driving device for appropriately improving a response of an SMA actuator will be provided. 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.
