摘要： Acoustic radiators which are focused diffractively by multi-discrete-phase binary Fresnel lenses are provided for applications, such as acoustic ink printing. Standard semiconductor integrated circuit techniques are available for fabricating such lenses in compliance with design specifications having relatively tight tolerances, including specifications for integrated lens arrays demanding substantial precision in the relative spatial positioning of several lenses. The diffractive performance of these lenses simulate concave refractive lenses, even though the lenses preferably have generally flat geometries. To that end, the lenses advantageously are defined by patterning acoustically flat surfaces, such as an acoustically flat face of a substrate or, better yet, an acoustically flat face of a layer of etchable material which is grown or otherwise deposited on an acoustically flat surface of an etch resistant substrate.

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： Method and apparatus which uses harmonic cantilevers, such as used in atomic force microscopy, to detect variations in the attractive and repulsive forces on a solid surface as a result of macromolecular binding, for example, hybridization of a single stranded DNA molecule attached to the surface with another DNA molecule. The complexed macromolecule is less flexible than an uncomplexed molecule. It will typically have more negative charge due to amino acids or DNA monomers. Both stiffness of the surface and the attractive capillary forces will change after binding and may be detected. By scanning the harmonic cantilever across a surface with macromolecules attached in tapping-mode and by recording the signals at the high frequency vibrations provided by harmonic cantilever, complexed molecules on a surface may be identified and quantified.
