    • A plurality of arrangements for detecting an overload of energy supplied to an output part enables selecting latch-off or auto-recovery overload protection by the operation of a switching device. When the drain current peak of the switching device exceeds a predetermined level denoting an overload, the FB pin voltage also rises to latch off, and when the drain current peak then reaches a maximum level, the CC pin voltage drops to a predetermined level and limits the oscillation period of the switching device because output power cannot be increased even if the load increases further. Latch-off overload protection can be applied when the drain current peak exceeding a predetermined level is detected, and auto-recovery overload protection can be applied when the CC pin voltage is detected to drop to a predetermined level.
    • 用于检测提供给输出部件的能量过载的多个布置使得能够通过开关装置的操作来选择闭锁或自动恢复过载保护。 当开关器件的漏极电流峰值超过表示过载的预定电平时,FB引脚电压也上升到锁存状态,当漏极电流峰值达到最大值时,CC引脚电压下降到预定值 即使负载进一步增加,开关器件的振荡周期也不能增加。 当检测到超过预定电平的漏极电流峰值时,可以应用锁存过载保护,并且当检测到CC引脚电压下降到预定电平时,可以应用自动恢复过载保护。

    • An electrostatic attraction fluid jet device of the present invention is so arranged that a nozzle (4) is formed so as to correspond to a meniscus equivalent to a tip portion in the form of a taylor cone formed in a process of an electrostatic attraction of ink (2) as a conventional fluid. A diameter of an ink-ejecting hole (4b) of the nozzle (4) is set to be substantially the same as a diameter of the tip portion, which is about to be ejected, of the meniscus (14) of ink. Moreover, the diameter of the ink-ejecting hole (4b) of the nozzle (4) is set to be equal to or less than a droplet diameter of the ink (2) which has just been ejected. Therefore, it is possible to provide an electrostatic attraction fluid jet device which can realize a recording device which has high resolution, is safe and is highly versatile.
