摘要： An ink drop deflector mechanism is provided. The ink drop deflector mechanism includes an ink drop source and a path selection device operable in a first state to direct drops from the source along a first path and in a second state to direct drops from the source along a second path. The first and second paths diverge from the source. The mechanism also includes a system which applies force to drops travelling along at least one of the first and second paths with the force being applied in a direction so as to increase the divergence of the paths. The mechanism may include a gas source which generates a gas flow force that is applied in a direction that increases the divergence of the paths. The gas flow may be positioned between the first and second paths. The gas flow may be substantially laminar and interact with at least one of the first and second paths as the gas flow loses its coherence. The mechanism may also include a catcher with at least a portion of the system being positioned adjacent the catcher. Alternatively, at least a portion of the system may be integrally formed in the catcher.

摘要： There is provided by this invention a unique printing system that utilizes a notch deflector in the ink delivery channel of a continuous ink jet printing system to control the angle of deflection ink droplets in a print and non-print direction. The width and depth of the notch in the ink delivery channel can be varied to produce different angles of deflection of the ink droplets for a given velocity of ink through the channel. Also, for any predetermined width and depth of the notch in the ink delivery channel, the deflection angle of the droplets will vary with varying velocities of ink flow. Control circuits are connected to the notch deflector to adjust the depth of the deflector for different angles of deflection.

摘要： A printer includes a printhead and a source of liquid. The printhead includes a nozzle bore. The liquid is under pressure sufficient to eject a column of the liquid through the nozzle bore. The liquid has a temperature. A thermal modulator is associated with the nozzle bore. The thermal modulator is operable to transiently lower the temperature of the liquid as the liquid is ejected through the nozzle bore. An electrical pulse source is in electrical communication with the thermal modulator. The electrical pulse source is operable to provide a series of pulses to the thermal modulator that control the transient temperature lowering of the liquid. The series of pulses includes a first pulse applied at a first power level for transferring heat to the liquid, a second pulse applied at a second power level for transferring heat to the liquid, and a third pulse applied at a third power level for transferring heat to the liquid. The third power level is in between the first power level and the second power level.

摘要： An actuator is made by depositing an electrode layer on an initial layer. A patterned layer of sacrificial material is formed on the first electrode layer such that a region of the first electrode layer is exposed through the subsequent layer. A second electrode layer is deposited and patterned on the subsequent layer. Then, a third patterned layer of sacrificial material is formed on the second electrode layer with an opening there through to the exposed region of the first electrode layer. A structure is deposited, patterned and planarized on the third layer expose a surface of the third layer. A third electrode layer is deposited and patterned on the planarized structure and the exposed surface of the third layer. The sacrificial material is partially removed, whereby the first electrode layer, the structure, and the third electrode layer are free to move together relative to the second electrode layer.

摘要： A liquid emission device includes a chamber having a nozzle orifice. Separately addressable dual electrodes are positioned on opposite sides of a central electrode. The three electrodes are aligned with the nozzle orifice. A rigid electrically insulating coupler connects the two addressable electrodes. To eject a drop, an electrostatic charge is applied to the addressable electrode nearest to the nozzle orifice, which pulls that electrode away from the orifice, drawing liquid into the expanding chamber. The other addressable electrode moves in conjunction, storing potential energy in the system. Subsequently the addressable electrode nearest to the nozzle is de-energized and the other addressable electrode is energized, causing the other electrode to be pulled toward the central electrode in conjunction with the release of the stored elastic potential energy. This action pressurizes the liquid in the chamber behind the nozzle orifice, causing a drop to be ejected from the nozzle orifice.

摘要： For an inkjet printhead (10) with integral compensation for misdirection of ink drops (37) ejected through at least one nozzle (24) of the printhead (10), a system and method of modifying the nozzle cavity space (32a) so as to compensate for the effects of defects in the printhead (10) by altering the direction the ejected ink drops (37). The inkjet printhead (10) comprises at least one reservoir (28) integrated within the membrane (30). The inkjet printhead (10) also comprises a channel (38) extending from the reservoir (28) and terminating in the nozzle cavity (32). A hardening substance (40) within the reservoir (28) and channel (38) is a plastic material having a high thermal expansion coefficient. An internal heater (48) within the reservoir (28) and adjacent the hardening substance (40) is adapted to cause the plastic material (40) to flow in order to form a protrusion (44) of plastic material (40) within the nozzle cavity space (32a). Alternatively, the plastic material (40) can be recessed within the channel (38). Thus, the hardening substance (40) is adapted to internally alter the nozzle cavity space (32a) and cause ink (34) ejected from the nozzle opening (26) to be deflected with regard to a desired amount of compensation.

摘要： A pump includes two opposing plates having a space there between to define a secondary fluid passage. A first aperture is formed through the first plate and a second aperture is formed in the second plate to define a primary fluid channel extending across the secondary fluid channel. A heater on the second plate moves primary fluid through the primary fluid channel due to the Marangoni type effect. A heater on the first plate causes a meniscus to enlarge to thereby form a drop of fluid ejected out of the primary fluid channel.

摘要： An imaging apparatus capable of inhibiting inadvertent ejection of a satellite ink droplet and method of assembling same. The imaging apparatus comprises a print head transducer including a pair of sidewalls defining a chamber therebetween, the channel having the ink body disposed therein. The transducer is in fluid communication with the ink body for inducing a first pressure wave in the ink body in order to eject an ink droplet. A waveform generator is connected to the transducer for supplying voltage waveforms to the transducer, so that the transducer induces pressure waves in the ink body. However, the first pressure wave has a reflected portion formed by the first pressure wave reflecting from the sidewalls. The reflected portion is sufficient to otherwise inadvertently eject unintended satellite ink droplets. Thus, a sensor is in fluid communication with the ink body for sensing the reflected portion and is connected to the transducer for inducing a second pressure wave in the ink body. The second pressure wave has an amplitude and phase damping the reflected portion of the first pressure wave in order to the inhibit inadvertent ejection of satellite ink droplets.

摘要： Pagewidth image forming system and method. The system features a plurality of mechanically isolated transducers capable of pressurizing an ink body associated with each of plural nozzle so that an ink meniscus extends from the ink body. The transducers are operated such that the ink bodies are uniformily intermittently pressurized. An ink droplet separator is also provided for lowering surface tension of the meniscus. In this regard, the droplet separator lowers the surface tension of the meniscus at a selected nozzle as the meniscus extends from the ink body, so that the meniscus forms a neck portion thereof. The extended meniscus severs from the ink body at the neck portion as the droplet separator lowers the surface tension to a predetermined value so as to form an ink droplet.

摘要： Self-cleaning printer with reverse fluid flow and method of assembling the printer. The printer comprises a print head defining a plurality of ink channels therein, each ink channel terminating in an ink ejection orifice. The print head also has a surface thereon surrounding all the orifices. Contaminant may reside on the surface and also may completely or partially obstruct the orifice. Therefore, a cleaning assembly is disposed relative to the surface and/or orifice for directing a flow of fluid along the surface and/or across the orifice to clean the contaminant from the surface and/or orifice. The cleaning assembly includes an oscillatable septum disposed opposite the surface or orifice for defining a gap therebetween. Presence of the oscillatable septum accelerates the flow of fluid through the gap to induce a hydrodynamic shearing force in the fluid. This shearing force acts against the contaminant to clean the contaminant from the surface and/or orifice. A pump in fluid communication with the gap is also provided for pumping the fluid through the gap. As the surface and/or orifice is cleaned, the contaminant is entrained in the fluid. A filter is provided to separate the contaminant from the fluid.
