摘要： The free ink surface levels of acoustic ink printers are controlled by cap structures that have substantially non-retroreflective aperture configurations. The non-retroreflective configurations of the apertures of these cap structures cause diffusive scattering or directional deflection of the reflected surface ripple waves, thereby significantly reducing the time that is required for the oscillatory perturbations, which are caused by reflection of the surface ripple waves that are generated during the droplet ejection process, to dissipate to a negligibly low amplitude in the critical local areas of the ejection sites. This, in turn, increases the droplet ejection rates at which printers having such cap structures can be operated asynchronously.

摘要： In accordance with the present invention, an acoustic ink printer comprises a pool of liquid ink having a free surface in intimate contact with the inner face of a perforated membrane. The printer addresses all pixel positions within its image field via substantially uniform, relatively large diameter apertures which extend through the membrane on centers that are aligned with respective ones of the pixel positions. In operation, one or more focused acoustic beams selectively eject individual droplets of ink from the ink menisci that extend across the apertures. Accordingly, the membrane is positioned and the bias pressure that is applied to the ink is selected so that the menisci essentially remain within the focal plane of such beam or beams.

摘要： Techniques for obtaining an ejection rate independent, spatial relationship between an acoustic focal area and the free surface of a liquid. Variations in the spatial relationship are reduced or eliminated by applying substantially the same acoustic energy to the liquid's free surface during periods when droplets are not ejected as when they are, but at power levels insufficient to eject a droplet. During ejection periods in which a droplet is not ejected, the acoustic energy is applied at a lower level, but for a longer time. Because it is more convenient to measure and control, the transducer drive voltage is used to control the acoustic energy applied to the liquid's free surface.

摘要： An ejector for ejecting droplets from an ink-filled reservoir is disclosed. The ejector comprises a substrate with a generally planar surface. The substrate is submerged in the reservoir so that the substrate surface is parallel to the reservoir surface at a shallow predetermined depth. On the substrate surface around a center is a plurality of concentric, circular electrodes. A coupled oscillator excites the electrodes in a temporal relationship such that the capillary waves generated at the ink reservoir surface are reinforced so that droplets may be ejected from the reservoir at the center of the electrodes.

摘要： Provision is made for selectively addressing inividual crests of traveling or standing capillary surface waves to eject droplets from the selected crests on command. To that end, the addressing mechanism of this invention locally increase the surface pressure acting on the selected crests and/or locally reduce the surface tension of the liquid within the selected crests. The preferred addressing mechanisms have sufficient spatial resolution to address a single crest substantially independently of its neighbors.Discrete addressing mechanisms having a plurality of individual addressing elements are especially attractive for liquid ink printing and similar applications, not only because their individual addressing elements may be spatially fixed, but also because the spatial frequency of their addressing elements may be matched to the spatial frequency of the capillary wave. Such frequency matching enables selected crests of the capillary wave to be addressed in parallel, such as for line printing. Preferably, the capillary wave for a printer is a spatially stabilized standing wave, so that the crests and troughs of the capillary wave are locked in predetermined spatial locations.

摘要： A printhead for an acoustic printer comprises one or more acoustic microlenses, each of which brings an acoustic beam to focus approximately at the free surface of a pool of ink for ejecting individual droplets of ink from the pool on demand. As used herein, an "acoustic microlens" is defined as being an acoustic lens having an aperture diameter which is less than an order of magnitude greater than the wavelength of the incident acoustic wave (i.e., the acoustic wave which illuminates the lens).

摘要： The output surface of an acoustic printhead having one or more concave acoustic beam forming devices for supplying focused acoustic beams to eject droplets of ink on demand from the surface of a pool of ink is planarized by filling those concave devices with a solid material having an acoustic impedance and an acoustic velocity which are intermediate the acoustic impedance and the acoustic velocity, respectively, of the ink and of the printhead. This not only facilitates the cleaning of the printhead, but also eliminates the edges upon which an optional ink transport or the like may tend to drag. The outer surface of the filler may be essentially flush with the face of the printhead, or the filler may overcoat the printhead.

摘要： To facilitate the fabrication of acoustic printheads, arrays of spherical acoustic lenses are provided for bringing rf acoustic waves to essentially diffraction limited focii at or near the free surface of a pool of ink. These lenses produce focal patterns which are relatively free of localized amplitude variations, so they may be employed to fabricate acoustic printheads having relatively stable characteristics for acoustic printing.

摘要： Provision is made spatially stabilizing standing capillary surface waves in fixed and repeatable locations with respect to stationary external references. For spatially stabilizing such a wave on the free surface of a volume of liquid, the wave propagation characteristics of the free surface of liquid are periodically varied in a spatially stable manner at a spatial frequency equal to the spatial frequency of the standing wave or a subharmonic thereof, thereby locking the crests and troughs of the standing wave in predetermined spatial locations. A spatially periodic pattern of notches in a wall or base plate bounding the free surface of the liquid may be employed to physically modulate its wave propagation characteristics at a suitable spatial frequency. Alternatively freely propagating secondary capillary surface waves may be launched from spatially periodic sites along the free surface of the liquid to actively modulate its wave propagation characteristics at the diesired spatial frequency.
