  • Publication number: 20110034712
    Abstract: A method of extracting essential oil from biomass wastes puts biomass wastes, such as wood residuals, wood chips or other plants, in an air-tight oxygen-free reaction vessel to be heated up indirectly, for conducting a thermal pyrolysis cracking reaction (i.e. dry distillation); and guides volatile gas which is distilled when the processed wastes disintegrate, into a condenser to be condensed as liquid which is then separated into water and oil through an oil-water separation tank. Whereas, non-liquefied gas is discharged outside after deodorizing, and residuals in the reaction vessel are processed with high-temperature dry distillation once to become activated carbons.

  • Patent number: 7839070
    Abstract: A field emission device has pixels with cathode and anode provided on the same plane, so that electrons directly penetrate an independently provided fluorescent powder layer to produce light, giving the display the advantages of easy focusing, no dark spots, high brightness, and enhanced light emitting performance. Since the light produced by the fluorescent powder layer is not blocked by the anode, the problem of charge accumulation on the fluorescent powder layer is avoided, and it is not necessary to use expensive light-transmittable conducting glass as the anode. With the cathode and the anode located at the same plane, it is not necessary to use a high precision spacer to maintain a fixed distance between the cathode and the anode, enabling the device to be manufactured at reduced cost and high good yield.

  • Patent number: 7830078
    Abstract: A field emission backlight module has a field emission structure with cathode and anode provided on the same plane, so that electrons directly penetrate an independently provided fluorescent powder layer to produce light. The light is emitted uniformly without the need of the conventional optical membrane. Since the light produced by the fluorescent powder layer is not blocked by the anode, the problem of charge accumulation on the fluorescent powder layer is avoided, and it is not necessary to use expensive light-transmittable conducting glass as the anode. With the cathode and the anode located at the same plane, it is not necessary to use a precision spacer to adjust the distance between the cathode and the anode, enabling the module to be manufactured at reduced cost and high good yield. When the color sequential displaying method is adopted, expensive color filters required in the conventional LCD may be omitted.
