摘要： A linear compressor drive device (101) comprising an inverter (2) for supplying a drive current of a specified frequency to a linear compressor (100), wherein an inverter controller (6) is provided to control the inverter (2) so that the frequency of an output current therefrom is a resonance frequency based on resonance frequency information and to measure the instantaneous values of the output current Id and output voltage Vd of the inverter (2) at a phase timing that renders zero a change in the output current Id of the inverter (2) to thereby calculate a piston stroke from the measured values. Such a linear compressor drive device (101) can detect accurately the piston stroke and top clearance of a linear compressor by a simple processing without using a position sensor.

摘要： In a plasma-display-panel driving method, a field period is divided into a plurality of sub fields, each of which has an address period for allowing discharge cells to selectively generate an address discharge and a sustain period for allowing the discharge cells having generated the address discharge to generate a sustain discharge by a number of times corresponding to a brightness weight. In the sustain period, a period for setting display electrode pairs to the base potential is disposed between the sustain pulse for causing the final sustain discharge in the sustain period and the previous sustain pulse. In a time interval corresponding to the lighting ratio of the discharge cells in the sub field after applying to the display electrode pairs a voltage for generating the final sustain discharge, a voltage for reducing the potential difference between electrodes of the display electrode pairs is applied to the display electrode pairs. Accordingly, it is possible to generate a stable address discharge and thus to reduce a crosstalk without increasing the voltage for generating the address discharge.
摘要翻译：在等离子体显示面板驱动方法中，场周期被分成多个子场，每个子场具有用于允许放电单元选择性地产生寻址放电的寻址周期和用于允许已经产生的放电单元的维持周期寻址放电以产生对应于亮度权重的多次维持放电。在维持期间中，用于将显示电极对设定为基本电位的期间设置在用于引起维持期间中的最终维持放电的维持脉冲与前一维持脉冲之间。在对显示电极对施加用于产生最终维持放电的电压之后的与子场中的放电单元的发光比相对应的时间间隔中，将用于减小显示电极对的电极之间的电位差的电压施加到显示电极对。因此，可以产生稳定的寻址放电，从而在不增加产生寻址放电的电压的情况下减少串扰。

摘要： A linear compressor driving apparatus (101) according to the present invention is a linear compressor driving apparatus having an inverter (2) which supplies a driving current of a predetermined frequency to a linear compressor (100), and the apparatus further includes an inverter controller (6) for controlling the inverter (2) on the basis of resonance frequency information so that the frequency of an output current from the inverter becomes equal to the resonance frequency, and instantaneous values of an output current Id and an output voltage Vd from the inverter (2) are measured at a phase timing in which an amount of change in the output current Id of the inverter (2) becomes zero, and a piston stroke is calculated from these measured values. In such linear compressor driving apparatus (101), a stroke and a top clearance of the piston of the linear compressor can be accurately detected by relatively simple arithmetic processing, without using a position sensor.
