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 ink jet printing apparatus and method for generating droplets of a printing liquid from a nozzle of an inkjet printhead features a temperature responsive vibrating beam constrained at both ends of the beam within or near a nozzle having an exit opening, the beam being continuously vibrated within the printing liquid in response to electrical pulsing applied to the beam so that the beam vibrates at a predetermined frequency and the beam is at a temperature that is characterized by frequency of vibration that is substantially at a local minimum point whereby minor excursions in temperature of the beam from the local minimum point temperature provides substantially minimal changes in frequency and amplitude of vibration of the beam. A heating element located at or near the exit outlet of the nozzle is selectively heated to provide a heat pulse to a meniscus of the printing liquid at the nozzle exit outlet to selectively control droplet formation and/or droplet direction leaving the printhead.

摘要： An inkjet printhead for printing an image on a printing medium is provided that includes a substrate having an interior and a nozzle face, a plurality of nozzles having outlets in the nozzle face, an electronically-operated droplet deflector disposed adjacent to each of the nozzle outlets, and feedthroughs for connecting the droplet deflector to power and image data circuits through the substrate interior. The feedthroughs include bores disposed through the substrate for accommodating conductors connected between the droplet deflectors and power and image data control circuits of the printer. The feedthroughs may take the form of bores either coated or filled with electrically-conductive material. The use of feedthroughs through the printhead substrate avoids the manufacture of an undesirably high density of connectors and conductors on the nozzle face and facilitates the manufacture of smooth and flat nozzle faces which are easily cleaned during the printing operation by wiping mechanisms. The power feedthroughs may be easily manufactured via MEMS bulk micromachining technology at the same time the substrate ink channels are formed.

摘要： Drop-on-demand ink jet printer capable of directional control of ink drop ejection and method of assembling the method. The method comprises a print head body having an ink ejection orifice adapted to poise an ink meniscus thereat about a center axis passing through the orifice. A deflector is coupled to the print head body and is adapted to be in communication with the poised meniscus for lowering surface tension of a region of the poised meniscus. The poised meniscus deflects away from the region of lower surface tension and away from the center axis to define a deflected meniscus, whereby an ink drop separated from the deflected meniscus travels at an angle with respect to the center axis, so that the ink drop can strike a receiver at any one of a plurality of predetermined locations on a print line.

摘要： A method of manufacturing a pump [10] for pumping various primary fluids. A body is formed from silicon dies [102,104]. A primary fluid channel [110] is formed in the body and a primary fluid supply [122] is coupled to the primary fluid channel [110] to supply a primary fluid to the primary fluid channel [110]. A mechanism for introducing a secondary fluid to an interface region of the primary fluid channel [110] is formed in the body. An energy delivery device is formed in the body to deliver energy to an interface between region between the primary fluid and the secondary fluid to create a thermal gradient along the fluid interface. The thermal gradient results in a surface tension gradient along the interface. The primary fluid will move to compensate for the surface tension gradient. Various semiconductor fabrication processes can be used to form the elements on the body.

摘要： A continuous ink jet print head is formed of a silicon substrate that includes integrated circuits formed therein for controlling operation of the print head. An insulating layer or layers overlies the silicon substrate includes conductors at various levels to provide conductive paths for transmitting control signals for controlling the print head. The insulating layer or layers also has a series or an array of nozzle openings or bores formed therein along the length of the substrate to provide a substantially planar surface to facilitate cleaning of the printhead. Each nozzle opening is formed as an elongated bore that extends through the insulating layer or layers to the silicon substrate. A heater element is formed adjacent each nozzle opening and in proximity to the planar surface to provide asymmetric heating of the ink stream as it leaves the nozzle opening.
