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： In a fluorescent display tube, a metal spacer is used as a height sustaining member and a fixing member of linear member so that the fixing strength of the linear member in the lengthwise direction is increased. In the fluorescent display tube, both ends of filament and Al wires are bonded onto a cathode electrode formed on a substrate by ultrasonic bonding. The ends of the filament are embedded in a part in the Al wires in the shape of being bent into a letter Z or an inverted letter Z to form fixing portion.

摘要： An electron tube, such as a fluorescent display tube, is disclosed. The electron tube includes plural cathode filaments, each of which has the same diameter and a different length. In order to adjust the resistance of each filament, the plural filaments are not serially connected, but effective length of each filament, which contributes to the emission of electrons, is adjusted without serially connecting plural filaments.

摘要： A phosphor heat-treating method and an apparatus therefor capable of providing a phosphor exhibiting improved crystallizability and increased in concentration of a luminous center therein. A phosphor is heated and rapidly cooled in atmosphere gas of a predetermined pressure. The pressure substantially restrains decomposition and scattering of the phosphor during heating and cooling of the phosphor.

摘要： A powder agitator used for an ion implantation device or an ionized beam deposition device capable of exhibiting satisfactory powder agitating characteristics and minimizing positive charging on powders. The powder agitator includes a base, a vessel for receiving powders therein, a plurality of supports for supporting the vessel on the base, and a pair of piezoelectric elements arranged on the supports and functioning as a vibration generating section. Application of a voltage to the piezoelectric elements causes the vessel to be oscillated in a direction of rotation of the vessel and a speed of oscillation of the vessel to be varied depending on a direction of oscillation of the vessel, resulting in agitating the powders in the vessel.
