Some kinds of singular dynamic phenomena observed in gas discharge field were investigated. These are electrostatic Moses effect, corona jet phenomenon, and electrostatic water jet phenomenon.1. Electrostatic Moses effect : Over a threshold voltage, corona discharge took place in a pin-to-plate electrode system and a relatively large repulsive force, in the order of 100 чN, was induced due to the ionic wind. It depressed water and a large depression of water, in the order of several 100чm at the center, was observed even to the naked eye. This phenomenon was utilized for a driving force of a micro-machine.2. Corona Jet Phenomenon : Lateral whirling of the pin electrode was observed at corona discharging when the pin electrode was extremely fine. Whirling frequency was increased with the increase of the applied voltage. Axial repulsive force due to the ionic wind was the cause of the whirling.3. Water Jet Phenomenon : When high voltage was applied between an insulative capillary tube filled with water and a metal plate electrode, water jet phenomenon was observed. This is expected to be utilized for a new inkjet printhead.New mechanism of electrostatic paper-separation and paper-feed systems was also proposed to realize highly a reliable paper handling system for printers.

研究了气体放电场中观察到的几种奇异动态现象，包括静电摩西效应、电晕喷射现象和静电水喷射现象。 1． -板电极系统和由于离子风而引起的相对较大的斥力，大约为100μN，它压低了水并且在中心观察到了大约几百μm的大水压。 2．电晕喷射现象：当针电极极细时，观察到针电极的横向旋转。离子风引起的轴向排斥力的增加是旋转的原因。 3．水射流现象：当在充满水的绝缘毛细管和液体之间施加高电压时。观察到了金属板电极的水喷射现象，这有望用于新型喷墨打印头。还提出了静电纸张分离和送纸系统的新机制，以实现打印机的高度可靠的纸张处理系统。
