摘要： Disclosed are ionographic imaging apparatuses and processes. One apparatus comprises an imaging means, means for applying to the imaging means a liquid material capable of forming a dielectric peel layer adhering to the imaging means, ionographic writing means for generating a latent image on the peel layer, means for developing the latent image on the peel layer, and means for simultaneously transferring the peel layer bearing the developed image from the imaging means to a substrate and affixing the peel layer bearing the developed image to the substrate. In another embodiment, the apparatus employs a process which comprises applying to an imaging means a liquid material capable of forming a dielectric peel layer adhering to the imaging means, forming a first latent image on the peel layer with an ionographic writing means, developing the first latent image with a first developer, forming a second latent image on the peel layer containing the first developed image with an ionographic writing means, developing the second latent image with a second developer, forming a third latent image on the peel layer containing the first and second developed images with an ionographic writing means, developing the third latent image with a third developer, and simultaneously transferring the portion of the peel layer that bears the developed images to a substrate and affixing the peel layer bearing the developed images to the substrate. A further embodiment is directed to an apparatus and process for sequentially forming and developing primary color images on an imaging means to form a full color image, followed by trasnsferring the fully formed image to a substrate, wherein the developers employed contain a release agent.

摘要： A gyricon or twisting-particle display based on nonspheroidal (e.g., substantially cylindrical) optically anisotropic particles disposed in a substrate. The particles can be either bichromal or polychromal cylinders, preferably aligned parallel to one another and packed close together in a monolayer. A rotatable disposition of each particle is achievable while the particle is thus disposed in the substrate; for example, the particles can already be rotatable in the substrate, or can be rendered rotatable in the substrate by a nondestructive operation performed on the substrate. In particular, the substrate can be made up of an elastomer that is expanded by application of a fluid thereto so as to render the particles rotatable therein. A particle, when in its rotatable disposition, is not attached to the substrate. The close-packed monolayer configuration of particles provides excellent brightness characteristics and relative ease of manufacture as compared with certain other high-brightness gyricon displays. The substrate containing the cylinders can be fabricated with the swelled-elastomer techniques known from spherical-particle gyricon displays, with a simple agitation process step being used to align the cylinders within the sheeting material. Techniques for fabricating the cylinders are also disclosed.

摘要： A gyricon or rotating-particle display having an "eggcrate" substrate. The display includes a substrate having a cavity-containing matrix whose cavities are disposed substantially in a single layer and are arranged within the matrix substantially in a geometrically regular pattern, and a plurality of optically anisotropic particles disposed in the cavities in the substrate, with each cavity containing at most one of the optically anistropic particles. A rotatable disposition of each particle is achievable while the particle is thus disposed in the substrate; the particle, when in its rotatable disposition, is not attached to the substrate. Each particle, for example, can have an anisotropy for providing an electrical dipole moment, the electrical dipole moment rendering the particle electrically responsive such that when the particle is rotatably disposed in an electric field while the electrical dipole moment of the particle is provided, the particle tends to rotate to an orientation in which the electrical dipole moment aligns with the field. The single layer of cavities can be substantially planar, and the geometrical pattern of cavities can be a two-dimensional array pattern in the plane of the layer, such as a hexagonal, rectangular, or rhomboidal array pattern. The substrate can further include first and second members between which members the matrix is disposed; at least one of the members can include an optically transmissive window through which a flux of optical energy can pass so as to be incident on the particles.

摘要： An externally stimulated continuous stream ink jet printer which suppresses or controls the formation of satellite droplets so that they are not charged differently from the main droplets. Thus, when the two are merged, indeterminate charges are not produced which would impact the print quality of the printer. The satellites are suppressed by impressing on the printer ink streams a combination of time-varying pressures. In one embodiment, the time-varying pressures are generated by two time-varying voltages applied to the EHD electrodes. One pressure has a fundamental frequency with the second pressure having a second harmonic frequency, these two pressures having a predetermined phase and amplitudes with respect to each other. The fundamental frequency is selected for a required drop spacing to stream diameter ratio.
