Intracycle Evaporative Cooling in a Vapor Compression Cycle (NISTIR 5873)

September 1, 1996
Author(s)
B. S. Kim, Piotr A. Domanski
The temperature glide of zeotropic mixtures during phase change provides the opportunity to limit throttling losses of the refrigeration cycle by intracycle evaporative cooling of the refrigerant leaving the condenser. Intracycle evaporative cooling is

Magneto-Optical Indicator Film Study of the Magnetization of a Symmetric Spin Valve

September 1, 1996
Author(s)
Valerian I. Nikitenko, V S. Gornakov, L M. Dedukh, Yury P. Kabanov, A F. Khapikov, Lawrence H. Bennett, P J. Chen, Robert D. McMichael, Michael J. Donahue, L Swartzendruber, Alexander J. Shapiro, H J. Brown, William F. Egelhoff Jr.
A magneto-optical indicator film (MOIF) technique is used for direct experimental study of the magnetization reversal process in a symmetric NiO/Co/Cu/NIFe/Cu/Co/NiO spin valve. It is shown for the first time that the reversal of the free center layer

New Certified Length Scale for Microfabrication Metrology

September 1, 1996
Author(s)
James E. Potzick
The National Institute of Standards and Technology is developing a dimensional pitch standard covering the range 1 micrometers to 10 mm, intended for the calibration of microscope magnification and of dimensional metrology instrument scales. Called SRM

Ultrasonic Power Output Measurement by Pulsed Radiation Pressure

September 1, 1996
Author(s)
Steven E. Fick, Franklin R. Breckenridge
Direct measurements of time-averaged spatially integrated output power radiated into reflectionless water loads can be made with high accuracy using techniques which exploit the radiation pressure exerted by sound on all objects in its path. With an
