    摘要： In an ink drop writing system it was found that the drops formed by vibrating a nozzle would be accompanied by smaller satellite drops which could be detrimental to printing. This condition was considerably improved by designing the nozzle so that it would have a mechanical resonance at the frequency at which it formed drops. In order to insure a most efficient transfer of power from the driving source into the drop forming mechanism, the nozzle had to be designed to provide a fluid resonance condition. If the nozzle be considered as a closed pipe, then the frequency of vibration of the fluid in the pipe at which its length is an odd multiple of a quarter wavelength of sound through the fluid in the pipe, results in the highest power transfer.

    摘要： In an ink drop printer, the adverse affects of the charge on a just formed drop upon the charge on a following ink drop being formed is compensated for, enabling the use of every ink drop for printing and thus affording better and faster printing.

    摘要： In a system wherein a stream of ink emitted from a vibrating nozzle passes through a charging tunnel wherein the ink stream breaks up into drops and the drops are charged by video signals, an arrangement is provided for insuring that the ink drops formed within the charging tunnel have the correct phase to receive a proper video signal.
