  • Patent number: 7479736
    Abstract: A display device capable of realizing a desired color temperature is provided. Phosphor layers 5a, 5b and 5c, which are excited by ultraviolet radiation produced by discharge and emit red, green and blue visible light, are formed inside a red, green and blue gas discharge tube 1a, 1b, and 1c, respectively. The height Yc of the phosphor layer 5c with respect to a rear support body 20 is higher than the heights Ya and Yb of the phosphor layers 5a and 5b with respect to the rear support member 20, and establishes the relationship Yc>Ya=Yb. Therefore, the distance from the phosphor layer 5c to the opposite discharge surface on a front support body is shorter than those from the phosphor layers 5a and 5b, the visible light emitted from the display device 10 is shifted toward blue, that is, the color temperature increases.

  • Patent number: 7468624
    Abstract: A step-down power supply receives an external power supply voltage and supplies power at a reduced voltage from an output node to a load. The power supply also receives a reference voltage and a control signal indicating the whether the load is active or not. The reduced power supply voltage is held equal to the reference voltage by adjustment of the voltage at an internal control node. To prevent fluctuations in the reduced power supply voltage at active-inactive transitions of the load, the power supply includes circuitry for pulling the voltage at the internal control node both up and down, circuitry for leaking current from the output node to ground, circuitry for temporarily raising and lowering the reference voltage, or a capacitor coupling the reference voltage signal line to the control signal line.

  • Publication number: 20080224590
    Abstract: A gas discharge tube is manufactured by closing an opening of a glass tube by forming a glass layer with outer peripheral shape identical to the outer peripheral shape of the glass tube on an end face of the glass tube. An open end face (opening) of the glass tube is pressure-welded to a dry film containing a low melting point glass powder and a binder resin, and then the glass tube is lifted up to transfer the dry film for closing the opening to the end face of the glass tube. A phosphor support member is inserted into the glass tube from a side opposite to the end face and then an end of the phosphor support member is caused to adhere to the dry film. The binder resin is burnt off, and the dry film is vitrified to produce a low melting point glass layer.

  • Patent number: 7339312
    Abstract: A gas discharge tube includes a thin tube having a discharge space therein and an electron emissive coating formed within the thin tube. The thin tube has a display surface on which a pair of display electrodes is adapted to be disposed, and has a rear surface on which a signal electrode is adapted to be disposed. A surface portion facing toward the display surface is formed within the thin tube at a location nearer to the display surface from the midway between the display and rear surfaces. An electron emissive coating is formed on the surface portion. Thus the gas discharge tube can reduce its firing voltage without lowering the light-emission efficiency.

  • Patent number: 7282858
    Abstract: A gas-discharge tube has a glass tube as its main body and a trench is provided in the axial direction of the glass tube on one surface (the surface opposed to the discharge surface) among the external surfaces of the glass tube. An address electrode is placed in the trench. The inner surface of the region of the glass tube where sustain electrodes are placed is formed to have a microscopic unevenness. A secondary electron emission film is formed on this inner surface where the unevenness is formed. In addition, a phosphor support member, whose cross section across the axis is in approximately a C-shape and where a phosphor layer has been formed in advance on the inner surface, is placed inside of the glass tube. Stable discharge characteristics is obtained by eliminating dispersion of the position of an electrode, relative to the gas-discharge tube.

  • Publication number: 20070195700
    Abstract: This invention is to enable appropriate routing based on transition prediction of network traffic. This routing control method includes: reading out predicted utilization transition data (e.g. utilization rate, or utilized bandwidth) associated with a received connection set-up request from a predicted utilization transition data storage storing said predicted utilization transition data for each resource (e.g. links between routers, or server) in a network in future; and selecting a resource satisfying a predetermined condition based on the read predicted utilization transition data. Thus, by using said predicted utilization transition data, an appropriate resource is identified in accordance with future time transition of the resource utilization rate, for example, and thereby, appropriate routing is possible.
