Scanning Electron Microscopy with Polarized Electrons

April 15, 1987
Author(s)
john unguris, G Hembree, Robert Celotta, Daniel T. Pierce
The recent joining of scanning electron microscopy and electron spin polarization analysis has greatly improved the ability to study magnetic microstructure. By measuring the spin polarization of secondary electrons, scanning electron microscopy with

A Cell Control Architecture for Flexible Manufacturing

April 1, 1987
Author(s)
Charles R. McLean
The software architecture of the cell control system in the Automated Manufacturing Research Facility (AMRF) at the National Bureau of Standards is presented. The cell control system manages production and support operations for an automated small batch

Control of an Automated Machining Workstation

April 1, 1987
Author(s)
Jay S. Jun, Charles R. McLean
The software architecture of the Vertical Machining Workstation (VWS) in the Automated Manufacturing Research Facility (AMRF) at the National Bureau of Standards is presented in this paper. This prototype system demonstrates flexible computer integrated

Measurement of the superconducting energy gap in La-Ba-Cu oxide and La-Sr-Cu oxide

April 1, 1987
Author(s)
Stephen E. Russek, P. E. Sulewski, A.J. Sievers, H. D. Hallen, D. K. Lathrop, R A. Buhrman
We report on far-infared (FIR) reflectivity measurements on sintered pressed poweder samples of La-Ba-Cu oxide and La-Sr-Cu oxide. THe best samples show fairly sharp transitions to zero measurable resistance with a transition midpoint of 28 K for the Ba

The Architecture of the NBS Factory Automation Research Testbed

April 1, 1987
Author(s)
Charles R. McLean, Peter Brown
A small batch manufacturing system testbed, currently under construction at the U.S. National Bureau of Standards (NBS), is designed to support research in factory automation standards. One of the expressed goals of the NBS Automated Manufacturing Research

Thermal Performance of Masonry Chimneys and Fireplaces (NBSIR 87-3515)

April 1, 1987
Author(s)
Richard D. Peacock
A series of tests was conducted in a masonry chimney and a masonry fireplace both constructed to current national standards in order to evaluate the effectiveness of recent changes to the building code requirements for residential masonry construction.

A method for the synthesis of bi- and polycyclic hydrocarbons

March 5, 1987
Author(s)
Anzor Mikaia, Leonid S. Glebov, Vladimir G. Zaikin, Alexey Yatsenko, OA Lesik, George A. Kliger, Sergai Loktev
Reaction gas chromatography-mass spectrometry is applied to establish optimal conditions for the synthesis of bi- and polycyclic hydrocarbons. Further optimization of the reaction was carried out in a pilot plant.
