摘要： PURPOSE: To increase the carrier density to get an input face with high sensitivity by forming a transparent conductive film by sputtering method, under specified condition, using a specified sputter target. CONSTITUTION: On the phosphor layer 7 made on the inner surface of an aluminum substrate 6 0.5mm in thickness is a transparent conductive film 8 made by sputtering method so that it may be colored, with the transmissivity of the film in the range of 50-70%, limiting the partial pressure of oxygen at sputtering to be under 1.0%, using the sputter target consisting of indium oxide powder of 70% in sintering density including tin oxide by 5wt.%. Next, a photoelectric face 9 is made in vacuum to get an X-ray image tube. Indium oxide is put in reductive condition by oxygen loss by limiting the partial pressure of oxygen at sputtering to be 1% or under, and making the transmissivity to 50-70% this way, whereby electron carriers by oxygen cavity are generated within the film to increase the carrier density, consequently high sensitiveness can be obtained.

摘要： PURPOSE: To decrease the light component with a large outgoing angle, prevent the Fresnel reflection at an output window glass, and improve the contrast by providing recesses with a specific depth on the core glass of each fiber on the opposite surface to an output phosphor layer.
CONSTITUTION: A fiber plate 17 which is a substrate is composed of many fibers, and each fiber is constituted with a core glass 101, a covering glass 102, and an absorber 103. An output phosphor layer 10 made of many phosphor grains 201 is formed on one surface of such a fiber plate 17. In addition, recesses 19 are provided on the opposite surface to the output phosphor layer of the core glass 101 of each fiber of the fiber plate 17 respectively. When this recess 19 is too shallow, the contrast is not improved; when it is too deep, the concave wall portion of the fiber plate 17 becomes weak and no favorable result can be obtained; and a favorable result can be obtained when the depth is within a range of 1W20μm.

摘要： PURPOSE:To prevent easy occurrence of electric discharge phenomenon, construct an X-ray image tube in a small size, and enhance the producibility and reliability by making a convergence electrode in the form of a conductive film evaporated fast onto the inner surface of a vacuum envelope, and applying a graduation treatment to the anode side end of this conductive film. CONSTITUTION:A convergence electrode 15 is constructed in the form of a conductive film which is evaporated fast onto the inner surface of a vacuum envelope 11, and the end 15b of this conductive film is subjected to a graduation treatment, which is applied on the side where an anode 13 is arranged having a potential difference from the potential impressed on the conductive film 15. Accordingly the electron emission characteristics are smoothened and the electric discharge phenomenon is difficult to occur because of this graduation treatment, which was applied in order for electrons not to be emitted easily at the end of the conductive film as the convergence electrode 15. This allows constructing an X-ray image tube in a small size and enhances the producibility and reliability.

摘要： PURPOSE:To use an optical fiber bundle plate to a substrate and to obtain a fluorescent screen for a high grade image having excellent contrast and luminance by providing recesses on the phosphor layer side of the optical fiber bundle plate and forming the phosphor layer on the surface except the recesses. CONSTITUTION:Recesses 18 are formed by etching in using an acid on the surface of the core glass 101 of an optical fiber bundle plate 17. Phosphor particles 201 are deposited on the surface of the plate 17 formed substantially by the end faces of the covering glass 102 of the respective unit fibers, by which an output phosphor layer 10 is formed. Therefore, the particles 201 hardly contact with the glass 101 and the light emitted by the particles 201 by an electron beam propagates in the optical fibers while making total reflection therein as shown by (a), (b), (c) in the figure, thus obviating illuminating another position of the layer 10 and improving remarkably the contrast. The fluorescent screen for a high grade image having excellent contrast and luminance is thus obtd.

摘要： PURPOSE:To obtain a X-ray image tube in which degradation of contrast is prevented by using a black insulating member which is provided facing the input side from an outer surface of a substrate in an output plane. CONSTITUTION:A cylindrical insulating member 14 for high voltage is provided facing the input side to hold an output fluorescent layer 9 from an outer surface of a substrate 8, and the insulating member 14 is made of a black material, e.g. black silicon. Therefore, when in operation, light having reached to the outer surface of the substrate 8 from a signal light 12 is absorbed by the black silicon insulating member 14. As the reflection which returns to the insulating member 14 from the first lens surface, which is not shown in the figure, is also absorbed, scattering is not generated. Degradation of contrast can be prevented accordingly.

摘要： PURPOSE:To improve the orientation of reflected light caused by the irregular reflection of light by forming the surface of a substrate on which an input phosphor layer is formed, into a mirror surface. CONSTITUTION:The surface of a substrate 12 on which an input phosphor layer 8 is formed, is formed into a mirror surface. Namely, the surface for forming the input phosphor layer 8 of the substrate 12 is preliminarily formed into mirror surface by buff polishing or by polishing using abrasives, and the substrate 12 is maintained at a predetermined high temperature, so as to form the input phosphor layer 8. The reflectance of the surface of the substrate 12 is drastically improved, and the orientation of the reflected light due to the irregular reflection of light is improved. An image intensifying tube of improved MTF and brightness characteristics can thus be obtained.
