Abstract:
In a fluorescent indicator tube wherein a cathode filament is provided in an envelope at a prescribed space from anode segments arranged on a substrate, one end of said cathode filament is fixed to a plate-shaped cathode filament-fixing rigid terminal fitted to one end of the substrate, and the other end of said cathode filament is attached to a plate-shaped cathode filament-fixing resilient terminal secured to the other end of the substrate. The plate-shaped filament-fixing resilient terminal comprises a plate member capable of being resiliently deformed in the direction in which the cathode filament is stretched and a frame securely supporting said plate member and fitting the whole of the resilient filament-fixing terminal to the substrate. The forward section of the deformable plate member is made broader than the rear section. The resiliently deformable plate member is bent outward, that is, in a direction in which the cathode filament is stretched, in order to prevent the cathode filament from touching the free end of the deformable plate member. A cutout line extending lengthwise of the deformable plate member is provided in the broader section. That portion of this broader section which projects from the rear section is bent upward along the cutout line. When one end of the cathode filament is placed between the bent portion and flat portion of the forward section of the deformable plate member, then the bent portion is folded up and welded to the flat portion securely to put therebetween and clamp the cathode filament.

An indicator tube having an anode structure and a hot cathode placed in front of the structure. The structure comprises a base plate and a plurality of phosphor anode segments which are capable of displaying at least one numeric, alphabetic, or similar figure. The tube dispenses with the conventionally required mask by embedding the anode segments within the base plate.
Abstract:
Overlaid alignment and mounting of a series of grid electrodes in spaced apart relation to a plurality of corresponding indicia electrodes on a substrate member of a display device is provided. A grid retaining member includes a series of grids retained by common opposing sides of a flex removable frame. Depression channels are provided at the retained ends of the grids whereby mounting pads are provided for accurately spacing grid and indicia surface portions, and whereby the various ones of the series of grids may be secured to corresponding ones of a series of terminal pads on the substrate. Protrusions from a base carrier member engage the peripheral walls of the various other members to provide alignment of grid surface portions with corresponding ones of the indicia electrodes. A method is described in which the members are internested in overlaid sequence above the base carrier member whereby fixed spaced-apart alignment of the grid and indicia surfaces is accomplished and whereby contact between various corresponding ones of the mounting and terminal pads is achieved. The respective grid mounting pads are then secured to corresponding ones of the terminal pads along the substrate member. The opposing side portions of the frame are thereafter flexibly broken away to provide electrical isolation of the grid electrodes.
Abstract:
A plastically shapeable cathode material is prepared by depositing on a nickel substrate a layer of a mixture of nickel or nickel oxide powder and barium, strontium and calcium carbonates; sintering in a neutral or reducing atmosphere the nickel substrate with deposited layer; compressing the sintered material; cold rolling the sintered and compressed material; annealing the resulting cold-rolled material; and repeating the latter two steps until the nickel substrate with deposited layer has a desired thickness.

Abstract:
Transition radiation from nanotubes, nanosheets, and nanoparticles and in particular, boron nitride nanomaterials, can be utilized for the generation of light. Wavelengths of light of interest for microchip lithography, including 13.5 nm (91.8 eV) and 6.7 nm (185 eV), can be generated at useful intensities, by transition radiation light sources. Light useful for monitoring relativistic charged particle beam characteristics such as spatial distribution and intensity can be generated.
