  • Patent number: 7006916
    Abstract: The navigation apparatus includes a unit for displaying a real image on a display screen on the basis of real image data, and a unit for displaying additional information such as a primary place name or a primary building name in a position where the additional information should be displayed on the real image, on the basis of additional information data corresponding to the additional information and position data showing the position where the additional information should be displayed. Further, the navigation apparatus has a function of limiting the display area of the additional information so as to prevent the additional information from being displayed in an area having a relatively high level of importance. Thus, the real image is prevented from being difficult to see in the area having a high level of importance.

    Abstract: A cold cathode display device includes a plurality of spacers in a space defined between a face substrate and a back substrate. The spacers are held by two fixing means consisting of fixing by fusion of a fixing material and fixing by dissolution of the fixing material. The invention provides an image display device which can realize the large-sizing of display size, the high-quality display and the prolonged lifetime by preventing the inclination and the removal of the spacers thus assuring the fixing strength and ensuring the parallelism and the panel strength of both substrates.

  • Patent number: 6958570
    Abstract: Inside an outer frame, which is interposed at between opposedly facing peripheries between a back substrate and a front substrate, there is an inner frame which fixes both end portions of plate member control electrodes, which are constituted of a large number of parallel strip-like electrode elements. By integrally forming the plate member control electrodes such that the plate member control electrodes are fixed to both end portions of a display region, a single part is formed. Further, a getter chamber is formed between the outer frame and the inner frame and getters are accommodated in the getter chamber. Due to such a constitution, the operability and yield rate of products at the time of assembling can be enhanced. Further, it is possible to hold a desired degree of vacuum in the space between the substrates for a long time.

  • Publication number: 20050212401
    Abstract: The present invention provides an image display device in which it is possible to obtain an image display of high brightness and high contrast by preventing the halation which may be generated in a peripheral portion of a display image. By providing a carbon film which attenuates the reentry of secondary electrons, which are generated when electron beams impinge on an anode, to a back surface of the anode, even when primary electrons impinge on the anode, the secondary electrons are hardly emitted from the anode. At the same time, a trace amount of emitted secondary electrons are mainly formed of electrons having a small energy. Hence, these emitted secondary electrons are scattered and hardly reenter the anode.

  • Publication number: 20040189266
    Abstract: A selector sets respective phases of pulse driving signals in reverse when a proportion signal or integration signal does not exceed a threshold. Shifting the respective phases of the pulse driving signals from each other lowers the ripple voltage. When the load current increases drastically, the output voltage Vo tends to decrease remarkably because of the shortage of capacity in the power supply. In this case, when the proportion signal or integration signal exceeds its corresponding threshold, a phase control unit causes the pulse driving signals to synchronize their phases, i.e., the selector supplies the same ramp wave to the comparators, so that respective output voltages supplied from the DC voltage converter circuits attain the same phase, thereby restraining the output voltage supplied to the load from decreasing remarkably.
