  • Patent number: 10297437
    Abstract: A sulfur plasma lamp has a lamp envelope of transparent or translucent glass or ceramic material. At least two silicon carbide electrodes are hermetically sealed with the lamp envelope and in contact with an interior of the lamp envelope. A quantity of sulfur within the interior of the lamp envelope is sufficient to create a sulfur plasma upon excitation. A buffer gas within the interior of the lamp envelope enables initial discharge and heating of the interior of the lamp envelope to excite the sulfur into a plasma state. More than two electrodes may be provided, and an electrical potential is created between different pairs of the electrodes at different times, thereby inducing stirring of the plasma upon excitation of the material into a plasma state.

  • Patent number: 8803423
    Abstract: To obtain effective luminance and light efficiency while avoiding discharge, it is necessary to sufficiently increase a current luminous efficiency of gas and an electron emission efficiency of an electron source. In a fluorescent lamp, an anode electric field is increased by setting a pressure of a noble gas or a molecular gas enclosed to 10 kPa or higher, setting an anode voltage to 240 V or lower, and setting a substrate distance to 0.4 mm or smaller. Furthermore, the resulting effect that the current luminous efficiency is increased in proportion to the electric field is used. Also, by applying a MIM electron source having an electron emission efficiency exceeding 10% as an electron source, a non-discharge fluorescent lamp having a light emission luminance equal to or larger than 104 [cd/m2] and a light emission efficiency equal to or larger than 120 [lm/W] is achieved.

  • Patent number: 8330365
    Abstract: A method for formation of a line pattern using a multiple nozzle head includes forming a cell region in which display cells with a height corresponding to a multiple of a line gap of nozzles provided to the multiple nozzle head are repeated in two dimensions; and forming different kinds of first and second line patterns alternatively repeated on the cell region by ink-jet printing using the multiple nozzle head. When the multiple nozzle head scans once, the first and second line patterns are formed at the same time under the condition that the height of the display cells and a gap between two associative line patterns are a multiple of the line gap of nozzles. This method may improve productivity by reducing the number of scans of the multiple nozzle head, and also decrease the possibility of open circuit occurring when forming a line pattern by ink jetting.

  • Publication number: 20100289413
    Abstract: An embodiment of the invention is a microcavity plasma device that can be controlled by a low voltage electron emitter. The microcavity plasma device includes driving electrodes disposed proximate to a microcavity and arranged to contribute to generation of plasma in the microcavity upon application of a driving voltage. An electron emitter is arranged to emit electrons into the microcavity upon application of a control voltage. The electron emitter is an electron source having an insulator layer defining a tunneling region. The microplasma itself can serve as a second electrode necessary to energize the electron emitter. While a voltage comparable to previous microcavity plasma devices is still imposed across the microcavity plasma devices, control of the devices can be accomplished at high speeds and with a small voltage, e.g., about 5V to 30V in preferred embodiments.
