We have investigated whether any force is generated by a spark discharge in a pin-to-plate system. Because it was difficult to measure the force directly over a short sparking period, three independent methods were employed to evaluate the magnitude of the force indirectly: (1) Axial vibration was observed for the pin electrode supported flexibly by a cantilever to the axial direction at the spark...
A new paper separation and feed mechanism is proposed to realize a highly reliable paper handling system for printers and copiers. The paper-separation system consisted of a pair of parallel electrodes and a paper pile between the electrodes. Electrostatic separation of a piece of paper was possible from the top of the pile when the applied voltage exceeded the threshold needed to generate an electrostatic...
