摘要： The present invention consists of an electroluminescent structure and method of fabrication of that structure in materials which have an indirect bandgap in their bulk form. The processing steps can all be standard VLSI methods. Quantum columns, quantum wires or quantum dots may be formed, for example in an array, by masking, reactive ion etching and oxidation. When the semiconductor core is sufficiently thin, quantum mechanical confinement effects raise the energy and the radiative recombination efficiency of injected carriers. Tuning the core diameters allows selection of individual or multiple wavelength emission bands.

摘要： A method of coating a liquid or solid particulate core involves dropping or suspending the particulate core in an atmosphere and then applying a liquid coating while the particulate core is dropped or suspended, the applying of the liquid coating being done by either (a) spraying the liquid coating onto the particulate core with an ink jet or (b) moving the particulate core through a fog of the liquid coating. In a further embodiment, the method can be used for encapsulating a liquid or solid particulate core within a polymeric shell by dropping or suspending the particulate core in an atmosphere, then applying by one of the above-mentioned methods a first coating composition containing a first reactant to the particulate core while the particulate core is being dropped or suspended, and subsequently exposing the particulate core coated with the first coating composition to a second composition containing a second reactant which reacts with the first reactant, which second composition is immiscible with the first coating composition, whereby the polymeric shell is formed by interfacial polymerization. By these methods, the formation of membranes or polymer shells around a variety of particulate core materials can be done using precise amounts of coating materials, thereby reducing waste and improving efficiencies of the process.

摘要： An external field activated display sheet is disclosed which comprises a plurality of hourglass shaped capsules for each pixel of an image. Each hourglass shaped capsule contains ink in one of its chambers. The ink in each hourglass shaped capsule is responsive to an external field being applied across the capsule for the movement from one chamber to the other. An opaque medial sheet blocks the visibility of the ink in the chambers under the medial sheet. Applying an external field across an hourglass shaped capsule causes the ink to be moved into the chamber above the medial sheet where it is visible. By applying an external field across selective hourglass shaped cavities, an image can be displayed.

摘要： An electrographic printing system comprises oppositely opposed print and complement electrode means to produce a dielectric breakdown through a recording medium transported in a printing gap between the electrode means. A visible mark or image is formed on the surface of the recording medium by (1) forming an aperture in a portion of the recording medium or through the recording medium, (2) ablating or eroding a minute portion of solid conductive pigment medium exposed through the formed aperture, (3) inducing the formation of a pigment aerosol from the explosive effect created during pigment ablation, (4) expulsion of the pigment aerosol through the formed aperture, and (5) confinement of the pigment aerosol to the lip of the formed aperture. The aerosol deposits in the form of a torus on the aperture lip and bonds to the surface of the recording medium. Aerosol containment is created by the employment of a dielectric collar surrounding the print electrode means and the provision of a dielectric overlayer on the surface of the recording medium.

摘要： A rotating element for use in an electric paper system in which the rotating element may be either substantially cylindrical or substantially spherical in shape and comprises at least three portions. Each portion has an associated optical modulation characteristic and the optical modulation characteristics of at least one portion are different from the optical modulation characteristics of at least one other portion. One of the portions is capable of being permanently magnetized. The rotating element also has an anisotropy for providing an electrical dipole moment. The electrical dipole moment renders the element electrically responsive such that when the rotating element is rotatably disposed in an electric field while the electrical dipole moment of the rotating element is provided, the rotating element tends to rotate to an orientation in which the electrical dipole moment aligns with the field.

摘要： A method of making rotating element sheet material utilizing magnetic latching is disclosed. First a plurality of rotating elements, each element having a magnetized segment, are mixed with an elastomer and a plurality of magnetic particles to attract the magnetic particles to the magnetized segments. Then a magnetic field is applied to orient the elements in a common direction. When the rotating elements have all been oriented in a common direction, they are held in that orientation for a long enough period of time to allow the magnetic particles to migrate in the elastomer to the regions of the elastomer in the vicinity of the magnetized segments of the elements. The elastomer is then cured to form an elastomer substrate with trapped rotating elements and magnetic particles. The elastomer substrate is then immersed into a bath of dielectric plasticizer which is absorbed more readily by elastomer than by the rotating elements. The elastomer substrate swells to create plasticizer-filled voids around the rotating elements. The magnetic particles remain incorporated within the elastomer to form magnetic material pads which are associated with an element.

摘要： An apparatus for forming magnetized rotating elements for a rotating element display where all the elements are magnetized in the same orientation is disclosed. The apparatus comprises at least one separator member. Each separator member has a diameter, two opposed surfaces and an edge region in contact with both of the surfaces. Further included is an apparatus for providing at least two liquid flows wherein each one of the liquid flows has an associated separator member and an associated surface on the associated separator member, and each one of the liquid flows is provided across the associated surface of the associated separator members. The liquid flow flows toward the edge region of the associated separator member. The liquid flows are each a flow of hardenable liquid material associated with an optical modulation characteristic, and at least one of the liquid flows containing a magnetic pigment. The separator members are spun and the liquid flows are merged outboard of the edge regions of the one separator members to form a reservoir containing side-by-side amounts of each liquid. When the flow rate of the liquids is high enough, a free jet approximately in a plane outward from the reservoir, the free jet comprising side-by-side amounts of each liquid from the reservoir is formed. A magnetic field, is provided outward from the formation of the free jet and at least a portion of the free jet is passed through the magnetic field to magnetize the magnetic pigment. The magnetic field is aligned transverse to the free jet. If cylindrical elements are desired then the magnetized free jet is hardened into filaments which can be separated into cylindrical elements. If spherical elements are desired then the free jet is broken up into spherical elements before hardening.
