    Abstract: Electron emission materials consisting of carbides, borides, and oxides, and related mixtures and compounds, of Group IVB metals Hf, Zr, and Ti, Group IIA metals Be, Mg, Ca, Sr, and Ba, and Group IIIB metals Sc, Y, and lanthanides La through Lu are used in electrodes. The electron emission materials include ternary Group IVB-IIIB, IVB-IIA, and IIIB-IIA oxides and quaternary Group IVB-IIIB-IIA oxides. These electron emission materials are typically contained in a refractory metal matrix formed of tungsten, molybdenum, tantalum, rhenium, and their alloys, but may also be used by themselves. These materials and electrodes have high melting points, low vapor pressures, low work functions, high electrical and thermal conductivity, and high thermionic electron emission and field emission properties.

    Abstract: A cathode for an electron tube, includes a base metal having nickel as a main component, and an electron emitting material layer containing an alkaline earth metal oxide having barium oxide as a main component, wherein a metal layer having zirconium as a main component is located between the base metal and the electron emitting material layer. The cathode has an excellent initial electron emitting characteristic and can emit a large quantity of electrons for a long time. Therefore, the cathode is suitable for a larger and higher-definition CRT.

    Abstract: A new Rhenium alloy usable for improving the performance of emission filaments used in mass spectrometers or other similar scientific instruments, which is made by adding low level concentrations of Yttrium Oxide to Rhenium of less than 10%. This new alloy has demonstrated superior performance characteristics compared to pure Rhenium for this purpose. Filaments made from the Yttria/Rhenium alloy exhibit the same voltage, current and emission properties as Rhenium but have the added advantage of greatly decreasing warping during use. The Rhenium alloy filaments are usable with various shapes and configurations including straight filaments, multiple coiled filaments and pin shaped filaments. Electron microscopy and microscopy studies verify that the Yttria/Rhenium material of the new alloy has a smaller grain size and increased strength when compared to pure Rhenium, which accounts for the enhanced structural strength.

    Abstract translation: 一种新的铼合金，可用于提高质谱仪或其他类似科学仪器中使用的发射丝的性能，这是通过向低于10％的铼添加低浓度的氧化钇而制成的。 与此相比，这种新型合金具有优异的性能特征。 由钇/铼合金制成的丝具有与铼相同的电压，电流和发射特性，但具有在使用过程中大大降低翘曲的附加优点。 铼合金丝可用于各种形状和构型，包括直丝，多丝线和针形丝。 电子显微镜和显微镜研究证实，与纯铼相比，新合金的氧化钇/铼材料具有更小的晶粒尺寸和增加的强度，这增加了结构强度。
