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： Acoustically thin capping structures and acoustic droplet ejectors having fluid wells and which use such capping structures to create fluid cells. The inventive capping structures permit the accurate positioning of the free surface of a fluid, permit acoustically induced fluid droplet ejection, and prevent fluid from spilling from the fluid wells. "Acoustically thin" means that the thickness of the capping structure is small enough that the acoustic energy that is lost passing through the capping structure is less than 50% of the incident acoustic energy.

摘要： This invention is an acoustic ink printer. It has a pool of ink (33) with a free surface (36). Underneath the ink is a print head (10) which has droplet ejectors (14) for irradiating the free surface (36) of the pool of ink (33) with focused acoustic radiation (44). Over the free surface (36) of the pool of ink (33) is a membrane (16), with one or more apertures (20) aligned with the droplet ejectors (14), in intimate contact with the free surface (36) of the pool of ink (33). The apertures 20 are substantially larger than the waist diameter (46) of the focused acoustic radiation (44). An external pressure source (50) maintains the meniscus (48) of the pool of ink (33) substantially in the focal plane (52) of the focused acoustic radiation (44) during operation of the droplet ejectors (14). A piezoelectric crystal (24) is in intimate contact with the pool of ink (33). An electrical signal source (32) energizes the piezoelectric crystal (24) in order to apply a pressure signal (54) on demand to the pool of ink (33) during operation of the droplet ejectors (14). The different pressure signals (54) resulting from application of different electrical signals (29) to the piezoelectric crystal (24) can be utilized to eject individual droplets (38) of ink (33) from the free surface (34) of the ink (33) on demand, or to effect finer control over the free surface (34) of the ink (33) than is possible with the external pressure source (50) by itself.

摘要： An acoustic microscope assembly for atomic level inspection of a target object includes a cantilever arm with a sharp tip on its lower surface and a zinc oxide piezoelectric thin film on its upper surface. High frequency excitation signals, having a frequency of at least 50 Megahertz, are applied to the piezoelectric thin film so as to generate high frequency acoustic signals that are transmitted through the sharp tip so as to impact on a target object. The assembly can either receive acoustic signals reflected by the target object, or it can receive acoustic signals that have propagated through the target object. One method of using this assembly is to apply a continuous wave signal to the piezoelectric thin film while scanning the target object, and measuring characteristics of the target object at various positions thereof by measuring the resonant frequency of the transmitted high frequency acoustic signals. Other methods include pulsed operation, and combining acoustic measurements with atomic force measurements and/or tunneling current measurements to characterize a target object. The acoustic microscope assembly can also be used for storing information on a substrate, by deforming the substrate at selected positions, and for reading such stored information by determining which positions on a substrate have been deformed.

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.
