  • Patent number: 5123868
    Abstract: A method of forming a electromagnetic radiator having cavities of predetermined dimensions involving coating a plurality of wires with an electromagnetic radiator material at predetermined thicknesses, the wires being soluble in a solvent and the radiator material being insoluble in the solvent, forming a bundle of a multiplicity of the coated wires, the coatings on the wires engaging each other, reducing the diameter of the bundle to a smaller predetermined diameter and fusing the coatings together with metallurgical bonds through the reduction thereby uniformly reducing the diameter of each of the coated wires and thicknesses of each of the coatings on the wires in the bundle, slicing partially through the fused bundle at predetermined regular intervals whereby to define the depth of the cavities, chemically removing the wires from inside the coatings whereby to form a foraminous electromagnetic radiator having an array of cavities of predetermined lengths and diameters formed by the drawn coatings.

  • Patent number: 5095245
    Abstract: The EL device includes a first electrode which is a transparent electrically conducting layer, a dielectric layer overlying the first electrode and a plurality of electroluminescent block members disposed in spaced relationship on the dielectric layer, each EL block member having a first surface disposed in contact with the dielectric layer and a distal second surface. A second or counter electrode which is formed of an electrically conductive layer is positioned in spaced relationship to the distal second surfaces of the electroluminescent block members. The dimensions of the electroluminescent block provide for preselected sonic isolation so as to provide for reduction of phonon waves of varying energies and increase the output brightness of the device.

  • Patent number: 5079473
    Abstract: An optical light source device includes a source member providing the emission of electromagnetic radiation wavelengths in the optical region of the spectrum, and at least one cavity waveguide member coupled with the electromagnetic radiation source member having a predetermined lateral dimension. The cavity waveguide member and predetermined dimension restrict the emission of electromagnetic radiation in the long wavelength non-visible infra-red range. In a preferred embodiment, the optical light source is formed with an array of optical light source members and associated cavity waveguide members.

  • Patent number: 5051649
    Abstract: A ballastless high pressure discharge lamp includes an arc tube, electrodes disposed in the arc tube, a column of mercury disposed in the arc tube and having a volume less than the volume of the arc tube, and cushion material disposed in the arc tube adjacent at least one of the electrodes. The cushion material comprises an inert gas impinging upon at least one end of the column of mercury. At least one of the electrodes extends into the column of mercury. The discharge lamp also includes a heating member disposed adjacent the arc tube to separate the column of mercury into two sub-columns by the vaporization of a portion of the mercury column to thereby form a space between the two sub-columns and compress the cushion material and allow one of the mercury sub-columns to engage one of the electrodes whereby to form an arc in the space between the two sub-columns of mercury.
