  • Patent number: 6291116
    Abstract: Disclosed are thermal transfer elements and processes for patterning solvent-coated layers and solvent-susceptible layers onto the same receptor substrate. These donor elements and methods are particularly suited for making organic electroluminescent devices and displays. The donor elements can include a substrate, an optional light-to-heat conversion layer, and a single or multicomponent transfer layer that can be imagewise transferred to a receptor to form an organic electroluminescent device, portions thereof, or components therefor. The methods offer advantages over conventional patterning techniques such as photolithography, and make it possible to fabricate new organic electroluminescent device constructions.

  • Patent number: 6008580
    Abstract: A plurality of discharge electrodes (23), (24) are formed on a first substrate (22) at an interval between the adjacent electrodes set to 50 .mu.m or smaller. A fluorescent layer (26) is formed on a second substrate (25 opposed to the first substrate (22). A sealed vessel (28) is formed by locating the first and second substrates (22) and (25) so that the electrodes (23) and (24) and the fluorescent layer (26) should be located on their inner sides. A predetermined gas is introduced in the sealed vessel (28) so that a pressure of the introduced gas should be within the range from 0.8 to 3.0 atmospheric pressure. Ultraviolet rays are produced by plasma discharge and make the fluorescent layer (26) emit light which is employed as illumination light.

  • Patent number: 5220237
    Abstract: A metal halide lamp apparatus includes a reflecting mirror and a metal halide lamp has a reflecting/thermal insulating film and a frost portion which is partially formed on the lamp outer surface within a predetermined range continued from the reflecting/thermal insulating film. This causes a decrease in an overall illuminance decrease and the attainment of a desired illuminance ratio and prevents the occurrence of irregularity in illuminance and color. In addition, since electrodes are asymmetrically disposed, it is possible to decrease the rate of devitrification of the luminous tube and make an attempt to increase the life of the luminous tube.

  • Patent number: 4885504
    Abstract: A hollow cathode assembly especially suitable for a boosted discharge hollow cathode lamp includes, a hollow cathode open at spaced apart ends, formed from a selected element which characterizes the assembly, and a cathode support. An anode is spaced from one of the open ends of the cathode, while an electron emitter has its outlet spaced from the other open end of the cathode. An inner envelope is provided to constrain the electron stream from the electron emitter to the anode to pass through the cathode. The cathode support is not insulated to prevent surface discharge therefrom but in operation of the lamp, the stream of electrons from the electron emitter through the cathode to the anode substantially confines surface discharge to the interior of the cathode.

  • Patent number: 4792732
    Abstract: A plasma generator for exciting electrons in the plasma to a uniform energy evel. In a perferred embodiment, two sets of mutually perpendicular electrodes surround a container of gas, with one set being driven through a ninety degree phase shifter to establish a circularly polarized field in the space within the container. Alternative means are disclosed for launching circularly polarized RF waves into the container of gas. A desired level of uniform electron energy is achieved by establishing the proper relationship between the frequency and magnitude of the applied circularly polarized field and the mean free path of the electrons in the plasma.
