In the IBM Technical Disclosure Bulletin article entitled "Making Gas Panel Displays" Vol. 17 No. 10 March 1975 pages 3136 and 3137, J. Landermann et al describe a gas panel structure, wherein the hermetic edge seal of the panel is made by direct sealing to the panel metallurgy and substrate.

In the fabrication of gas panel displays, typically the opposing plates are sealed together in air. In order to protect the metal lines, deposited upon each of the two plate glass substrates, from oxidation during sealing, the seal is made between the dielectric glass layers which have been deposited over the metal...

A variety of techniques exist for leak path location and identification in gas panel display devices. However, the bromine vapor test described here has been found to be more sensitive than any test heretofore known. The test has been found to be sensitive > or - 10/-10/ t-1/sec.

An important consideration for long life and stability in heterojunction lasers is effective heat sinking. While copper is not necessarily the best material for heat sinking, it does exhibit some advantages.

Type II superconductors have flux lines which can be used for storage of information. A device is provided using flux lines for storing information and persistent currents for generating a propagating or guiding pattern.

The computer analysis and design of integrated field-effect transistor (FET) circuits is essential for the establishment of a new technology. This task can be accomplished in a fast and efficient way in an interactive circuit design (ICD) environment [1]. The static and dynamic behavior of the circuits are simulated...

In using a computer-aided circuit design program, it is necessary to enter the circuit by using a commonly accepted input language to characterize the circuit. The language for a network element is typically of the following form: R1, N1 - N2 = 0.5 (1) where the key letter R of the left-hand side referred to as R1...

The placement of connected components on an array of locations is a recurring problem in the automatic design of circuit layouts; an extensive review of the methods was given by Hanan and Kurtzberg./1/ Two separate problems may be distinguished; for one, it is desirable to evaluate placements preparatory to wiring for...

An ellipsometer system is described for reducing or eliminating the effects of photodetector sensitivity to polarization of the light, which is used to measure the angular position of minima and maxima of the light reflected from a sample under examination.

This description relates to a convenient and efficient scheme for the processing of bipolar (BIP) transistors. Two intrinsic models can be implemented as a basic building block for bipolar transistor models. The circuit diagram for the two models is the same as shown in Fig. 1. It can be augmented to various models...
