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

摘要： Drive technology is provided which makes suitable low velocity driving and smooth changing of driving velocity possible and achieves reduced power consumption. In the driving device, the drive unit is driven which engages with drive shaft which moves back and forth in tandem with extension and contraction of the piezoelectric element. In this driving device, when the output cycle for cycle Te is repeated such that the voltages applied to the piezoelectric element 11 are the maximum value (+Vp), the minimum value (−Vp), and the middle value (0V), the movement velocity of the drive unit 13 can be changed by thinning the output cycle at cycle Tf. As a result, suitable low velocity driving can be carried out and power consumption can be reduced in the drive unit.

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.
