摘要： A high frequency power amplifier module of a multistage amplifier construction comprising: an input terminal; an output terminal; a control terminal; and a mode switching terminal. The first amplification stage includes a dual gate FET, and a bias voltage according to a signal is applied to the first gate and the second gate of the dual gate FET from the control terminal and the mode switching terminal, and a radio signal from the input terminal is applied to the second gate such as the source of the dual gate FET. In dependence upon the signal from the mode switching terminal, the mode of the high frequency power amplifier module is for the GSM (i.e., for a non-linear amplifying action) and for the, EDGE (for a linear amplifying action).

摘要： A piezo-electric actuator magnifies piezoelectric displacement through two-steps, provided by a first lever portion and a second lever portion which are connected by two plate springs. One of the plate springs transmits a tension force while the other plate spring located adjacent to the first plate spring works as a fulcrum. A higher magnifying power of displacement is obtained.

摘要： A mechanical amplifier for a piezoelectric actuator employs a lever-link system having a lever and a fulcrum to amplify a displacement caused by the piezoelectric effect of the piezoelectric element. A fulcrum supporting a last amplified lever forms a semi-pivotal construction to strengthen the stiffness of the amplifier. The invention converts electrical energy into mechanical energy for application to a printer or other electronic instruments.
