摘要： A field emission type fluorescent display device capable of exhibiting high luminescence under a low voltage while minimizing leakage luminescence and color mixing, to thereby improve display quality. An anode and a field emission cathode are arranged opposite to each other and the cathode is divided into a plurality of unit regions in a matrix-like configuration, which are matrix-driven, resulting in a display being selectively carried out. The unit regions each are divided into a plurality of subregions and the cathode and anode are divided into a plurality of strip-like electrodes perpendicular to each other, respectively. The strip-like electrode each correspond to each of subregions and are commonly connected to each other at every second interval. Also, a focusing electrode may be arranged between the gate and the anode so as to surround the unit regions.

摘要： A field emission element that can prevent one cathode electrode line from being completely disabled due to a short circuit between an emitter electrode and a gate electrode. One cathode electrode line consists of a stripe cathode conductor and plural island electrodes arranged on the one side of the cathode conductor. The gate electrode is disposed on the insulating layer overlaying the upper surface of each island electrode. The first resistance layer and the second resistance layer each having a different resistance value are laminated in a current control resistance layer. When excessive current flows through the emitter cone, the laminated thick-film portion is destroyed so that only the island electrode connected to the emitter cone is electrically separated off from the cathode conductor. One second resistance layer is locally laminated on the first resistance layer and for each of plural island electrodes.

摘要： A vacuum envelope with a built-in electron source capable of preventing peeling of gate electrodes, to thereby enhance reliability in operation over a long period of time and reducing a manufacturing cost thereof. The gate electrodes each are made of niobium oxide or niobium nitride. Nb for the gate electrode is previously oxidized or nitrided to prevent progress of oxidation of the gate electrode due to release of oxygen from lead oxide contained in a seal material during heating for sealing, resulting in expansion of the gate electrode. An insulating layer is formed on a cathode substrate and the gate electrodes are formed on the insulating layer. Then, the seal material is applied onto the insulating layer so as to cover a part of each of the gate electrodes, so that the cathode substrate may be sealedly joined to an anode substrate.

摘要： A getter support capable of permitting a getter to be compactly arranged in a vacuum envelope while keeping a space for the getter minimized. The getter support includes holders for vertically interposedly holding a getter, first support legs formed integrally with the holders so as to downwardly extend therefrom, and second support legs formed integrally with the holders so as to upwardly extend therefrom. The getter support is fixedly arranged in a getter chamber while being pressed by elasticity of the second support legs. The second support legs are varied in deflection depending on contact thereof with a second substrate of an envelope. This permits a distance between an upper surface of the getter and the second substrate of the envelope to be constantly kept at a desired value.

摘要： A low-velocity electron excited phosphor capable of exhibiting increased luminance and a method for producing the same. A matrix crystal for the phosphor is doped therein with an activator at implantation energy of 50 KeV by ion implantation, resulting in the activator entering a portion of the matrix crystal extending to a depth as small as 0.5 .mu.m from a surface thereof. Then, the phosphor is annealed for a reduced period of time as short as 10 seconds at a temperature of 900.degree. C. Such short-time annealing effectively prevents distribution of the activator in the matrix crystal formed during the implantation from being deeply spread into the matrix crystal by thermal diffusion. Thus, the activator concentratedly exists at only a portion of the matrix crystal in proximity to the surface thereof. Thus, the phosphor exhibits increased luminance as compared with a prior art, because luminescence of the phosphor is limited to the portion thereof in proximity to the surface.

摘要： An evacuation apparatus is capable of evacuating an envelope to a high vacuum without evacuating a whole room or chamber to a high vacuum. An evacuation pipe is connected at a distal end thereof to an evacuation head and a vacuum pump is actuated to evacuate an evacuation chamber to a high vacuum, to thereby evacuate an envelope to a high vacuum. Then, a motor is driven to rotate ball screws, to thereby upwardly move the envelope mounted on the evacuation head. The evacuation pipe is fused at an intermediate portion thereof by a gas burner, to thereby be sealed. Then, the evacuation pipe is cut to disconnect the envelope from the evacuation head.

摘要： An image display device capable of minutely setting the interval between an emitter (6) and a gate (5) with high accuracy and of being driven at a significantly reduced drive voltage with good emission uniformity. Each emitter (6) is provided in a recess in a substrate (2), so that the interval between the emitter (6) and a gate (5) is determined depending upon the thickness of the emitter (6). Thus, the interval can be readily controlled by adjusting or varying the period of time during which the film for the emitter (6) is formed, resulting in a micro-interval of the order of sub-microns between the two components being possible with high accuracy.
