摘要： A continuous liquid drop emission apparatus is provided. The liquid drop emission apparatus is comprised of a liquid chamber containing a positively pressurized liquid in flow communication with at least one nozzle for emitting a continuous stream of liquid and a jet stimulation apparatus adapted to transfer pulses of energy to the liquid in flow communication with the at least one nozzle sufficient to cause the break-off of the at least one continuous stream of liquid into a stream of drops of predetermined volumes. The continuous liquid drop emission apparatus further comprises a semiconductor substrate including integrated circuitry formed therein for performing and controlling a plurality of actions on the drops of predetermined volumes. The plurality of actions may include drop charging, drop sensing, drop deflection and drop capturing. Drop action apparatus adapted to perform these functions and integrated circuitry to control the drop action apparatus are formed in the semiconductor substrate. Jet stimulation apparatus comprised of a plurality of transducers including resistive heaters, electromechanical vibrators or thermomechanical vibrators, together with integrated control circuitry, may also be integrated on the semiconductor substrate. Silicon is a preferred material for the semiconductor substrate and CMOS and NMOS designs and fabrication processes are preferred for the integrated circuitry.

The jet break-off length control apparatus comprises a liquid drop emitter containing a positively pressurized liquid in flow communication with at least one nozzle for emitting a continuous stream of liquid. Resistive heater apparatus is adapted to transfer pulses of thermal energy to the liquid in flow communication with the at least one nozzle sufficient to cause the break-off of the at least one continuous stream of liquid into a stream of drops of predetermined volumes. A sensing apparatus adapted to detect the stream of drops of predetermined volumes is provided. The jet break-off length control apparatus further comprises a control apparatus adapted to calculate a characteristic of the stream of drops of predetermined volumes and adapted to provide a break-off length calibration signal to the resistive heater apparatus wherein the break-off length calibration signal is determined at least by the characteristic of the stream of drops of predetermined volumes. Further apparatus is adapted to inductively charge at least one drop and to cause electric field deflection of charged drops. The present inventions are additionally configured to control break-off lengths for a plurality of streams of drops of predetermined volumes by determining a break-off length calibration signal that contains information specific to the plurality of streams of drops of predetermined volumes. Jet stimulation apparatus comprised of a plurality of thermomechanical or electromechanical transducer devices that transfer mechanical energy to the fluid are claimed.

摘要： The present invention provides a method for reproducing image data from a press output on another device. The present invention mimics color, resolution and frequency of dots used by varying the color saturation (amplitude) of the dots used to mimic the defining characteristics of the source output. By allowing adjustments in both frequency and amplitude to vary from the original output device, it becomes possible to match the resolution and color of the source device.

摘要： A regulation system controls the print head pressures of a plurality of discrete ink jet printers of the continuous type to the same nominal pressure, while the printers use a common drive source to their own ink pumps. The regulation system includes bypass pressure detection passages extending from a tap in each printer's circulation system to a detection reservoir. Each bypass passage includes a bladder/valve portion whose exterior is in fluid communication with a detection fluid enclosed within the common reservoir. A transducer detects the pressure of the common reservoir and signals control of the common pump drive so as to regulate all print head pressures to the same nominal operating pressure.
