摘要： A jetting module (48) includes a nozzle plate (49), a thermal stimulation membrane (100), and an enclosure. Portions of the nozzle plate define a nozzle (50). The thermal stimulation membrane includes a plurality of pores (110). The enclosure extends from the nozzle towards the thermal stimulation membrane to define a liquid chamber (53) positioned between the nozzle and the thermal stimulation membrane. The liquid chamber is in fluid communication with each of the nozzle and the plurality of pores. The liquid chamber is spanned by a portion of the thermal stimulation membrane. A source provides a liquid under pressure through the thermal stimulation member with the pressure being sufficient to jet a stream of the liquid through the nozzle after the liquid flows through the thermal stimulation membrane.

摘要： A drop on demand ink jet print head has a chamber (18) with a plurality of liquid passages (36, 38, 42, 44) into and out of said chamber(18), such that liquid is continuously moved into the chamber (18) to a stagnation point adjacent to the nozzle opening (24), whereat the fluid comes substantially to rest, and out of the chamber (18) from the stagnation point such that vector sum of liquid flow derived forces within the liquid channels is neutral. An actuator (32) associated with the chamber (18) is adapted to selectively increase the pressure of the liquid at the stagnation point to thereby eject a liquid drop from the nozzle opening (24). Continuous fluid flow internal to the system decreases the time to refill the fire chamber directly behind the nozzle opening after droplet ejection. This in turn dramatically increases the response time of the system.

摘要： A continuous liquid ejection system includes a substrate (110) and an orifice plate315) affixed to the substrate. Portions of the substrate define a liquid chamber (310). The orifice plate includes a MEMS transducing member. A first portion of the MEMS transducing member is anchored to the substrate. A second portion of the MEMS transducing member extends over at least a portion of the liquid chamber and is free to move relative to the liquid chamber. A compliant membrane (320) is positioned in contact with the MEMS transducing member. A first portion of the compliant membrane covers the MEMS transducing member and a second portion of the compliant membrane is anchored to the substrate. The compliant membrane includes an orifice (135). A liquid supply provides a liquid to the liquid chamber under a pressure sufficient to eject a continuous jet of the liquid through the orifice located in the compliant membrane of the orifice plate. The MEMS transducing member is selectively actuated to cause a portion of the compliant membrane to be displaced relative to the liquid chamber to cause a drop of liquid to break off from the liquid jet.

摘要： A drop generator operable to selectively form a drop having a first size and a drop having a second size from liquid emitted through a nozzle associated with the drop generator. The drop having the first size and the drop having the second size travel along a drop trajectory with the first size being larger than the second size when compared to each other. Each of the drops has a drop velocity. A gas flow deflection system includes a gas flow that is directed at a deflection zone that comprises at least a portion of the drop trajectory. The gas flow in the deflection zone includes a velocity vector having a parallel velocity component and a perpendicular velocity component with the parallel velocity component and the perpendicular velocity component being defined relative to the drop trajectory.

摘要： An inkjet printhead includes two groups of interleaved nozzles. First and second sets of drop-formation waveforms are associated with the groups of nozzles to selectively cause portions of a liquid jet to break off into drops. A timing delay device time-shifts the second-group waveforms relative to those associated with the first-group waveforms. A charging-electrode waveform having portions with first and second potentials is provided to a charging electrode. The waveform energies of the second-group waveforms is larger than the waveform energies of the corresponding first-group waveforms so that printing drops break off from the liquid jets while the charging-electrode is at the first potential, and non-printing drops break off from the liquid jets while the charging-electrode is at the second potential.

摘要： An improved heater/electrode construction for a bubble jet print head of the kind having discrete ink heater elements (51) formed of electrically resistive material and a plurality of address electrode pairs (52, 53) formed of electrically conductive material and electrically contacting opposing edge regions of respective heater elements (51). The heater element resistance increases from its center outward and the electrode ends are spaced from the bubble formation region (Rc) to provide, in a drop ejection condition, a flat slope temperature profile along the current flow path through the bubble formation zone.
