摘要： PROBLEM TO BE SOLVED: To restrict deterioration in brightness characteristic of a fluorescent screen generated when an excitation density is increased for increasing brightness. SOLUTION: Phosphor material is coated on the surface with a group of plural protrusions of a polyhedron, a cone, a pyramid, a truncated pyramid, or a truncated cone to form a fluorescent screen 8, or phosphor material is formed into a group of plural protrusions in the form of a polyhedron, a cone, a pyramid, a truncated pyramid, or a truncated cone to be a fluorescent screen 8, so an excitation density by excitation beams is reduced while using zones of favorable brightness-excitation dose converting characteristics, and increasing light emitting area, thereby brightness deterioration by the reduction of the excitation density is compensated to improve brightness.

摘要： PROBLEM TO BE SOLVED: To prepare a fluorescent membrane which exhibits excellent characteristics in all of luminance saturation, luminance degradation and color tone, and to provide an image display device using the same. SOLUTION: The fluorescent membrane emitting/displaying images is composed of a two-layer membrane comprising a first phosphor layer 3 and a second phosphor layer 2 laminated thereon, and the average size of the phosphor particles in the second phosphor layer 2 that constitutes an electron-beam irradiated side layer is larger than that in the first phosphor layer 3. The second phosphor layer 2, to which an electron beam is irradiated from a negative electrode, is formed of a phosphor that has a larger size, less luminance saturation and better luminance degradation characteristics, while the first phosphor layer 3, that emits light primarily by a secondary electron beam, is formed of a phosphor that has a smaller size, thus pulling out the good characteristics of each phosphor, and improving all the characteristics that have been unsettled. This membrane exhibits good characteristics in all of luminance saturation, luminance degradation and color tone, that cannot be attained by the conventional fluorescent membrane of a signal layer or two-layer structure.

摘要： PROBLEM TO BE SOLVED: To obtain fluorescent substance which can easily give a cathode ray tube, which has heretofore been difficulty had a large-area screen display because of low luminance, capable of large-area screen display having high luminous efficiency and high definition by directly vapor-depositing a metal on the surfaces of fluorescent substance particles. SOLUTION: A phosphor 7 is deposited on a pressure-sensitive adhesive film. An organometallic complex such as (CH3 )3 Al is deposited on the deposited phosphor, and the whole is heat-treated to remove the organic part. That area of the fluorescent substance particle which is directly vapor-deposited is limited to the rear and side parts in relation to the direction of light power, and the thickness of the metal deposition on the side area in the direction of light power is thinner than that of the rear part. Next, an electron gun which emits electron beams is provided within the neck of a cathode ray tube composed of a face plate 2 to the inside of which a film of the fluorescent substance layer 8 is stuck, a funnel and a neck. Thus, the phosphor has high effectiveness on luminance and definition in a cathode ray tube which is irradiated with a high electric current, such as a projection type cathode tube.

摘要： PURPOSE:To readily provide a cathode-ray tube having a phosphor film of high packing density by forming a viscous film on the inner surface of the face plate of the cathode-ray tube, forming layers of phosphor particles on the film, and fixing the layers of phosphor particles while increasing the packing density through vibration or the like. CONSTITUTION:A deliquescent inorganic compound (e.g. zinc chloride) is mixed with a water soluble polymer (e.g. polyvinyl alcohol) to manufacture a viscous liquid. The viscous liquid is applied to the inner surface of the face plate 21 of a cathode-ray tube to form a viscous film. Next, layers of phosphor particles are formed on the viscous film and the packing density of the layers of phosphor particles is increased by a vibrating method, etc. Adhesive properties are provided between the face plate 21 and one layer of phosphor particles and between the layers of phosphor particles and thereby the layers of phosphor particles are fixed so as to form a phosphor film 22. Then an Al-evaporated film 23 is formed by a normal method and baking is performed and a neck tube 24 and an electron gun 25 are mounted to manufacture a cathode-ray tube.

摘要： PURPOSE:To shorten a duration of a normal conducting state by a method wherein a change in a state near a critical temperature of a superconductor is detected and this detected signal is transmitted to a cooling device in order to adjust the temperature so that a safety circuit to cope with a danger which brings the superconductor to a state of more than a critical point can be installed in order to detect that the critical point is exceeded and to quickly lower the temperature of the superconductor. CONSTITUTION:A small-sized coil 31 which is manufactured by using a superconducting wire material having a critical temperature of 90 deg.K is brought into contact with a copper block and is cooled. An electric current of 10-30A is made to flow through the wire material and is used as an electromagnet to measure a photomagnetic effect. when a temperature of the coil 31 exceeds its critical temperature due to an external cause, an electric current value is reduced suddenly. A transient current flows through a coil 32 due to this change. This current is differentiated and the detection sensitivity is raised; a Peltier element 34 is actuated with a switch 33 which is turned on by a differentiation signal. When the coil 31 is turned to a superconducting state again, the transient current flows through the coil 32 again and the switch 33 is turned off. By this setup, it is possible to keep a high- temperature superconductor device at a temperature below the critical temperature. In addition, it is not necessary to supply a freezing mixture and to use a cryostat; it is possible to use the device in a compact container.
