    摘要: A polar modulation transmission apparatus for realizing a wide control range for transmission power, maintaining the modulation precision and the distortion characteristic at a superb level even at a low output, and providing a high power efficiency is provided. An adder 102 adds a logarithm-represented transmission power control signal S13 to a logarithm-represented amplitude signal S14, and outputs the resultant signal as a transmission power-controlled amplitude signal S5. A phase modulation section 104 outputs a high frequency phase-modulated signal S8 based on a phase signal S3. An amplitude signal amplifier 103 supplies a supply voltage to a high frequency power amplifier 106 based on an amplitude signal S5. The high frequency power amplifier 106 performs amplitude modulation on the high frequency phase-modulated signal S8 based on the supply voltage supplied thereto, and outputs the resultant signal as a high frequency transmission signal S10.

    摘要: A determination is made whether a moving speed of a slider section with respect to a rod section in a piezoelectric actuator is lower than a predetermined speed. When the moving speed is lower than the predetermined speed, it is considered that a friction-bonded portion between the rod section and the slider section is in a fastened state or a nearly fastened state. A resonance frequency of the piezoelectric actuator or a frequency proximity to the resonance frequency is set as a driving frequency for the piezoelectric actuator. The slider section is moved in a reciprocating manner plural times with respect to the rod section. As a result, an abnormal state is eliminated from the piezoelectric actuator.

    摘要: A wireless transmission apparatus of multi-mode operation with superior power efficiency is provided. Switches (115 and 117) are switched over in such a manner that a modulation signal outputted from a wireless GSM/EDGE (UB) signal formation circuit (101-3) of a high-frequency signal processing circuit (101) is outputted to a high-frequency power amplifier (104) at the time of output of a GSM modulation signal, and is outputted to a high-frequency amplifier (105) at the time of output of an EDGE modulation signal. As a result, the EDGE modulation signal is power amplified using a high-frequency power amplifier (105) for an UMTS modulation signal use that is compatible with regards to the EDGE modulation signal and the maximum output power and presence or absence of envelope fluctuation. It is therefore possible to amplify the EDGE modulation scheme wireless signal with high efficiency.

    摘要: In a digital camera using an image pickup device such as CCD, a high resolution and properly exposed image is obtained by composition a plurality of image data of the same object taken by a plurality of image pickup operation when a luminance of the object is lower. Each image data is taken under a condition that an integration time (a charge storage time) of the image pickup device is shorter than a limit integration time causing a camera shake. A position of a frame on the image pickup device from which electric charges of the pixels are read out as the image data is corrected so as to cancel the movement of the camera between the image pickup operations.
