  • Patent number: 7053382
    Abstract: An object of the present invention is to provide an X-ray image tube which enables acquisition of an image of a proper density by increasing contrast without increasing an irradiation dose of X-rays. The X-rays absorbed or scattered through a subject emit light on an input surface formed in an input window, and the light is further converted into electrons on a photoelectric surface which converts the light into the electrons, accelerated and focused by a focusing electrode, and then guided to an anode side. The electrons guided to the anode side are made visible by a fluorescent substance, and an image of a color is projected on a glass plate with a luminance and a color based on a distribution of the incident X-rays in accordance with the dose of the X-rays.

  • Patent number: 6169360
    Abstract: The present invention assures a satisfactory adhesiveness of an input screen 13 of an X-ray image intensifier, high resolution of an output image and brightness uniformity as required, by configuring an aluminum or aluminum alloy substrate 21 so to have a concave surface with minute irregularities of the substrate material removed by burnishing, excepting gentle irregularities 21c without directivity which are caused by pressing. The gentle irregularities 21c of the substrate 21 preferably have an average length L in a range of 50 &mgr;m to 300 &mgr;m between the neighboring bottoms and an average height H in a range of 0.3 &mgr;m to 4.0 &mgr;m from peaks to bottoms. The invention improves resolution with light on the substrate surface suppressed from being scattered, and decreases image noises which are caused by the minute irregularities.

  • Patent number: 5916395
    Abstract: A method for fabricating ceramic electronic parts allows external electrodes to be baked onto the electronic parts without overlaying powder on the sagger. An adhesive material layer is provided on a surface of a sagger on which electronic parts are placed. The sagger is inserted into a firing oven with the electronic parts adhesively fixed onto the adhesive material layer, whereby the external electrodes of the electronic parts are baked. The adhesive layer burns away during the firing process. The method including such steps eliminates the need of overlaying powder onto the sagger, so that no powder sticks to the external electrodes after baking, so that the process of removing powder is no longer necessitated.

The input surface has a base and a phosphor layer formed on the base and having a predetermined effective radius. The phosphor layer includes a thickest portion which has a thickness about 105 to 115% of a thickness of a center of the layer and is located in a region spaced from the center toward the periphery of the layer by a distance about 60 to 80% of the effective radius. The phosphor layer is formed so that the thickness is gradually increased from the center to the thickest portion and a region between the thickest portion and the periphery of the layer has a thickness about 50 to 100% of the thickness of the thickest portion.
