Design, fabrication, and performance of a flat tube display

1977 International Electron Devices Meeting, 1977
A thin profile (two-inch depth) digitally addressed cathodoluminescent display has been developed which is capable of presenting 1920 alphanumeric 5 × 9 dot matrix characters at a spot brightness of 500 ft-L. Multilevel addressing techniques permit greatly reduced pinout (108 addressing levels for the A/N display versus 590 levels on equivalent plasma ...

A fully electrostatic, flat, thin television tube

Proceedings of the Institution of Electrical Engineers, 1968
A description is given of important improvements and modifications which have been made in the design of a flat television tube. In the new form, magnetic components have been eliminated and considerable structural simplifications have been made. An electrostatic deflection system is described which is capable of giving deflection angles of ±60°, and a

Flat-Plate and Evacuated Tube Collectors

2013
Solar-energy collectors are devices employed to gain useful heat energy from the incident solar radiation. They can be of the concentrating or the flat-plate type. A simple flat-plate solar energy collector consists basically of an absorbing surface which absorbs the insolation and transmit it in form of heat to a working fluid commonly air or water. A

Phosphor screens for flat cathode ray tubes

Philips Journal of Research, 1996
Abstract In the Zeus display panel, as in other flat-panel cathode ray tubes, the anode voltage is limited to a few kV. The effects of the anode voltage on phosphor screen performance are discussed which include energy conversion loss processes at the phosphor surface and variation of the number of luminescent centres available.

Numerical Investigation on a Flat - Tube Heat Exchanger in Metal Foam

Volume 8: Heat Transfer and Thermal Engineering, 2019
Abstract A numerical analysis on a heat exchanger in aluminum foam with flat tubes is accomplished. The flow equations in two-dimensional steady state regime are written considering the local volume averaging process. The foam considered as an open porous medium is modelled in local thermal non-equilibrium (LTNE) under the Darcy-Brinkman-

Tests on Deflection of Flat Oval Bourdon Tubes

Journal of Basic Engineering, 1959
To fill the gap in knowledge of Bourdon tube deflection data, the method and results of tests on 70 varied flat oval Bourdon tubes are given. The results are compared against published design data. The results are evaluated to determine the function of the deflection with respect to geometric parameters.

Optimization of the Structure of Flat Metal Tube Trusses

2020
Loading optimization of the metal trusses has a variational basis. The universal criterion of optimization is the minimum of potential energy of the system (additional energy) in functional space expanded at the expense of functions fields of configuration and (or) material modules, as well load.
