ELECTROGRAPHY IMAGE FORMATION AND DEVICE THEREFOR |
摘要 |
In electrographic printing Paschen breakdown must be exceeded for writing to occur, or the Paschen breakdown level can be used as a measure of the suitability of record media for use in such printing. The onset of Paschen breakdown is determined by the appearance or disappearance of second harmonic current flow across a test gap. The DC output of an integrator rises until the onset of Paschen breakdown occurs caused by the combination of the D C output and a sinusoidal voltage from an oscillator. |
