摘要： A cathode structure comprises a cylindrical metal sleeve having aperture portions at both ends, a base metal having an aperture portion on one end, which is fitted onto one of the aperture portions of the metal sleeve, and an electron-emitting layer, which is formed on a flat portion of an outside surface of the base metal. After an electron-emitting material is sprayed onto the base metal, its surface is mechanically flattened to form the electron-emitting layer. Thus, the planarity of the surface of the electron-emitting layer can be improved without deterioration of the electron emission characteristics and the moiré can be decreased without reduction of the resolution.

摘要： An impregnated cathode and a method of manufacturing the same are provided for suppressing emission of unwanted electrons and particles generated from an excess electron emitting substance so as to achieve a steady electron emission characteristic. The impregnated cathode is placed directly beneath an electron emission hole of a first grid. The impregnated cathode is made up of a first sintered porous element whose surface functions as an electron emitting region and a second sintered porous element whose surface is a peripheral region other than the electron emitting region. The porosity of the first sintered porous element is greater than that of the second sintered porous element. Not only the first sintered porous element having the electron emitting region but also the second sintered porous element corresponding to the region around the electron emitting region is impregnated with the electron emitting substance. In addition, the amount of the electron emitting substance per unit volume contained in the first sintered porous element is greater than that contained in the second sintered porous element.

摘要： A field emission device, which among other things may be used within an ultra-high density storage system, is disclosed. The emitter device includes an emitter electrode, an extractor electrode, and a solid-state field controlled emitter that utilizes a Schottky metal-semiconductor junction or barrier. The Schottky metal-semiconductor barrier is formed on the emitter electrode and electrically couples with the extractor electrode such that when an electric potential is placed between the emitter electrode and the extractor electrode, a field emission of electrons is generated from an exposed surface of the semiconductor layer. Further, the Schottky metal may be selected from typical conducting layers such as platinum, gold, silver, or a conductive semiconductor layer that is able to provide a high electron pool at the barrier. The semiconductor layer placed on the Schottky metal is typically very weakly conductive of n-type and has a wide band gap in order to create conditions conducive to creating induced negative electron affinity at applied fields necessary to provide electron emission. One type of wide band-gap material can be selected from titanium dioxide or titanium nitride or other comparable materials.

摘要： A cathode for an electron tube provided with a base containing at least one kind of reducing agent, a metal layer whose main component is tungsten formed on the base, and an electron emission material layer whose main component is an alkaline-earth metal oxide including barium formed thereon, deformation of the base in operation is controlled by composing the metal layer with a porous metal layer and limiting the thickness and the porosity of the metal layer. As a result, it is possible to achieve a cathode for an electron tube applicable to a cathode-ray tube for a display in which the cutoff voltage is liable to change.

摘要： An impregnated cathode whose initial electron emitting performance, lifetime property, and insulating property for an electron gun are excellent and that is suitable for mass production, and a method for manufacturing the same. In the impregnated cathode, the porosity of the sintered body of porous metal is continuously increased as the distance in the depth direction from an electron emitting face is increased. A pellet of sintered body of metal raw material has pores in it. The pores are filled with electron emitting material. The porosity is continuously increased as the distance in the depth direction from an electron emitting face is increased. Thus, since the discontinuity inside the pellet is not formed, a reaction generating free Ba continuously and smoothly proceeds on the entire pellet. In addition, since raw material powder having more than one kind of particle size is not necessary to be used, the manufacturing process can be simplified. Moreover, various functions such as lifetime property, etc. can be improved by making the porosity and porosity distribution in a certain range.
摘要翻译：其电子枪的初始电子发射性能，寿命特性和绝缘性能优异且适合于批量生产的浸渍阴极及其制造方法。在浸渍的阴极中，随着电子发射面的深度方向的距离增加，多孔金属的烧结体的孔隙率不断增加。金属原料烧结体的颗粒中有孔。孔被电子发射材料填充。随着距离电子发射面的深度方向的距离增加，孔隙率不断增加。因此，由于不形成丸粒内部的不连续性，因此在整个丸粒上连续且平稳地进行产生游离Ba的反应。此外，由于不需要使用具有多种粒径的原料粉末，因此可以简化制造工艺。此外，通过使孔隙率和孔隙率分布在一定范围内，可以改善诸如寿命性质等各种功能。
