摘要： An oxide cathode for an electron tube and a method for manufacturing the oxide cathode are provided. In the oxide cathode including a sleeve for a heater, a metal substrate formed on the top of the sleeve, and an electron emission material layer coated on the metal substrate, the electron emission material layer is formed by coating a carbonate paste containing an alkaline earth metal carbonate, an organic blowing agent, and a vehicle on the metal substrate by screen printing, and thermally treating the coated carbonate paste. Picture quality degradation due to a Moire phenomenon is reduced by coating the carbonate paste by screen printing to provide an even cathode surface, and degradation of the cathode by Joule heat is reduced, thereby improving electron emission and lifespan characteristics of the cathode.

摘要： A cathode for an electron tube and a preparing method therefor are provided. In the cathode for an electron tube having a base metal and an electron-emitting material layer, the particle size of the micro structure of the surface of the base metal is controlled to be in the range of 3 to 50 &mgr;m. The cathode for an electron tube has an excellent effect of diffusing intermediate products generated during the operation of the cathode, and is capable of consistently supplying a diffusion path of a reducing agent. Also, the cut off drift rate can be reduced, thereby attaining a long life span characteristic.

The shadow mask is placed behind the phosphor screen at a predetermined distance. A shadow mask frame is attached under the shadow mask to suspend it in the panel. The panel assembly further includes a plurality of stud pins embedded into the side-wall of the panel, a spring positioned between the shadow mask frame and the stud pins to interconnect them, and a vibration damping member for damping vibration of the shadow mask by converting mechanical stress applied to the shadow mask into electrical energy. The vibration damping member is formed with piezoelectric material layers provided on at least one of an outer periphery of the stud pin and between the spring and mask frame.

摘要： A metal cathode for an electron-emission device, and an indirectly heated cathode assembly employing the metal cathode where the metal cathode is formed of a quaternary alloy including 0.1-20% by weight barium (Ba), 0.1-20% by weight a metallic mobilizer facilitating Ba diffusion, a metal with a difference in atomic radius of at least 0.4 Angstrom from the atomic radius of platinum (Pt) or palladium (Pd), the metal being in the range of 0.01 to 30% by weight, and a balance of at least one of Pt and Pd. The metal cathode has a low operating temperature due to its reduced work function with improved current emission capability. The metal cathode can be used for a longer lifetime at high current density. Therefore, the metal cathode can be used effectively in electron-beam devices, such as a Braun tube or picture tube, satisfying larger size, longer life span, high definition, and high luminance requirements of the devices.

摘要： A spring used in a CRT interconnects a stud pin embedded into a CRT panel and a mask frame mounting a shadow mask thereon so that the spring removably mounts the shadow mask within the CRT panel. In order to minimize or interrupt a vibration energy transmitted to the shadow mask, the spring is formed with a composite metal plate having a laminated structure of more than two materials capable of converting the vibration energy applied thereto into a thermal energy by an internal or interfacial friction. The composite metal plate is preferably composed of a first steel, a zinc alloy, and a second steel. A method of making the spring includes the steps of plating two or more metallic materials in sequence, rolling the plated metallic materials into an integrated composite metal plate, and forming the composite metal plate into a spring shape.

摘要： A shadow mask includes an aperture portion having a plurality of apertures formed therein, the aperture portion being formed over a predetermined area in a center of the shadow mask; and a non-aperture portion defining a periphery of the shadow mask and formed adjacent to the aperture portion. Only the aperture portion is selectively heat-treated to result in a tensile strength of the aperture portion being 1.2 to 3 times greater than that of the non-aperture portion, and the modulus of elasticity of the aperture portion being 1.5 to 3 times greater than that of the non-aperture portion. The method includes the steps of selectively performing a heat-treating process on only the aperture portion of the shadow mask by mounting a separating cover on the non-aperture portion, the separating cover preventing contact of the non-aperture portion with the gaseous atmosphere present during the heat treating process. The shadow mask is then press-formed.
