摘要： An evaporable getter device for mounting in an electron tube is provided which comprises a pan-shaped container having a vertical side wall formed around the perimeter of a disc shaped bottom wall and a pulverized getter metal vapor releasing material pressed into the space formed by said side wall and said bottom wall.There is also provided a first heat transfer retarding means which delays the transfer of heat in a circumferential direction through the getter metal vapor releasing material. There is also provided a second heat transfer retarding means which delays the transfer of heat in a radial direction through the getter vapor releasing material. When the getter device is heated by currents induced from a radio frequency field created by a coil positioned outside the tube, opposite the getter device, high yields of getter metal are released in a short time without detachment of the getter material residues from the container.

摘要： A frittable evaporable getter device includes a metallic container having a disk-shaped bottom wall and a side wall extending upwardly from the bottom wall. A powder compact having an upper surface in which at least two radial recesses are formed is disposed in the container. The powder compact is formed of a mixture of BaAl.sub.4 powder and nickel powder. A discontinuous metallic member is embedded in the powder compact such that the member does not protrude from the upper surface of the powder compact and the member is spaced apart from the bottom wall of the container. An evaporable getter device having reduced activation time includes a powder compact formed of a mixture of BaAl.sub.4 powder, nickel powder, and between about 0.3% and about 5% by weight based on the total weight of the mixture of a third component selected from aluminum, iron, titanium, and alloys thereof.
摘要翻译：可卷曲的可蒸发的吸气装置包括具有盘形底壁和从底壁向上延伸的侧壁的金属容器。具有形成有至少两个径向凹部的上表面的粉末压块设置在容器中。粉末压块由BaAl4粉末和镍粉末的混合物形成。将不连续的金属构件嵌入粉末压块中，使得构件不从粉末压块的上表面突出，并且构件与容器的底壁间隔开。具有减少的活化时间的可蒸发的吸气装置包括由BaAl 4粉末，镍粉末的混合物形成的粉末压片，基于选自铝的第三组分的混合物的总重量的约0.3重量％至约5重量％铁，钛及其合金。
