    • A spacer, which is an atmospheric pressure resistant structure for a vacuum container, can be easily assembled, and the manufacturing costs that accompany the installation of the spacer are reduced. A rear plate, which includes a substrate on which electron-emitting devices are mounted, is located opposite a face plate that is irradiated by electrons emitted by the electron-emitting devices, so that together these two units constitute one part of the vacuum container. A spacer is positioned as an atmospheric pressure resistant structure in the vacuum container. Blocks are bonded to both ends of the spacer, and with these blocks, the spacer is self-supported. Both ends of the spacer are tapered, and are used to reduce the stress that is imposed on the bottoms of the spacer and the blocks by the rear plate and the face plate while air is discharged from the vacuum container.
    • 作为用于真空容器的耐大气压结构的间隔件可以容易地组装,并且减少了间隔件安装所带来的制造成本。 包括其上安装电子发射器件的衬底的后板与由电子发射器件发射的电子照射的面板相对,使得这两个单元一起构成真空容器的一部分。 间隔件在真空容器中被定位为耐大气压结构。 块结合到间隔物的两端,并且利用这些块,间隔物是自支撑的。 间隔件的两端是锥形的,并且用于在空气从真空容器排出空气的同时减小由隔板和面板施加在间隔件和块体的底部上的应力。
