Abstract (en)

[origin: US4275402A] A circuit arrangement for piezo-electric recording nozzles, in ink mosaic recording devices, to effect a temperature regulation of the control voltages therefor in which the respective recording nozzles are each provided with a control circuit for individually controlling the respective nozzles and which may be individually adjusted, in combination with a regulating circuit which is common to all of the control circuits, and includes temperature-dependent means for controlling the regulating means, whereby the latter supplies at its output a voltage which varies in accordance with the environmental temperature at such temperature-dependent means.
