  • Publication number: 20180304283
    Abstract: An electrostatic spray device including a voltage applicator and an isoelectric line adjustment electrode. The voltage applicator applies a voltage between a liquid sprayer and a heteropolar portion functioning as a pole opposite from a pole of the liquid sprayer to generate an electrostatic force. The isoelectric line adjustment electrode is made from a conductive material and adjusts equipotential curves appearing so as to surround the nozzle. The isoelectric line adjustment electrode obtains the equipotential curves at least partially drawing curvature gentler than curves of equipotential curves appearing near a front side of the nozzle in a state where the isoelectric line adjustment electrode is not disposed. The isoelectric line adjustment electrode is located near an outer periphery at a distal end of the nozzle and has an electric potential identical to an electric potential of the liquid sprayer such that the equipotential curves drawing the gentle curvature are obtained.

  • Patent number: 8894381
    Abstract: A compressor capacity control method and a device is provided. The changeover from a loading state regarding the compressor to an unloading state regarding the compressor and vice versa is controlled, whereby, during a time span from a starting time point when the compressor operation state changes into an unloading state to a time point when a loading/unloading operation-cycle is finished and a predetermined time duration has passed after the starting time point, the time cycle control is performed so that the loading state is changed into the unloading state, at a time point when the predetermined time duration has passed. Further, the discharge pressure of the fluid discharged from the compressor is detected so that the loading state is changed into the unloading state in a case where the discharge pressure exceeds a prescribed upper limit pressure.
