Abstract:
Jet printing studies during this quarter indicated that, although the transducers studied may not be feasible for piercing multiple sheets of paper, they may be useful for printing one or more copies by impact of the jet on carbon paper. The spark discharge method of jet energizing is considered impractical because of the high voltage levels required and because of problems arising from high operating temperatures. Barium titanate was adjudged the best practical piezoelectric material similarly, pure nickel is the best readily available magnetostrictive material. Possible jet production via a pressurized vessel with electromechanical valves was considered impractical and was not pursued. Gas tubes and neon lamps are potentially useful as electronic display sources for photographic or electrostatic printing. They can operate at high speeds and they are relatively inexpensive. Use with fiber optics would offer flexibility of construction methods. Other light sources, e.g., lasers, electroluminescence, and cathode-ray tubes, may be used in electrostatic printing. Methods of modulating the direction of a laser beam electrically may be useful for future printing devices, if cost becomes reasonable. Author
