Abstract: An ink jet nozzle structure comprising a thin tube, connected to a pressurized ink reservoir, is encircled by an A. C. driven coil which induces longitudinal reciprocating motion to cause formation of ink droplets. A permanent magnet is in the proximity of the drive coil provides a biasing action. The tube length is chosen so as to permit it to vibrate resonantly at the frequency of the induced longitudinal reciprocating motion. Resonant vibration permits the tube to be supported at two points along its length greatly increasing its mechanical stability. An air damper located near the tip of the nozzle broadens the resonant response and provides differential signals proportional to the longitudinal movement of the tube to maintain movements at a fixed or preset level.

Abstract: A gutter structure for catching discarded ink drops from an ink jet nozzle comprises a multisection electrode structure to separate drops having different phase relations. A relatively low calibrating voltage is applied to the drop charging electrode in conjunction with a character generation signal so that the calibrating voltage prevails to deflect drops whenever a drop is to be discarded. Circuitry connected to the different electrode sections controls the phase relation of the drop charging voltage and the drop formation in accordance with detection of the calibrating voltage drops to maintain the proper phase relations.
