A POLISHING MACHINE CONCEPT WAS DEVISED FOR NON-ABRASIVE POLISHING OF THREE INCH DIAMETER (OR LARGER) SEMICONDUCTOR WAFERS OF GAAS, INP AND SIMILAR MATERIALS. THE POLISHING PRINCIPLE IS BASE ON A TECHNIQUE DEVELOPED BY MIT LINCOLN LABORATORY SCIENTISTS CALLED "HYDROPLANE POLISHING OF SEMICONDUCTOR CRYSTALS". THIS NEW CONCEPT, HOWEVER, DOES NOT DEPEND ON THE CENTRIFUGAL DISTRIBUTION OF THE POLISHIN ...

THE OBJECTIVE IS TO CONSTRUCT, CYCLE, AND EVALUATE PROTOTYPES OF THE TITLE CELL USING A NEWLY DISCOVERED ELECTROLYTE/SOLVENT SYSTEM WITH HIGH CONDUCTIVITY AND LOW FREEZING POINT WHICH IS CAPABLE OF ABSORBING LARGE QUANTITIES OF BROMINE WITHOUT DISSOLVING LITHIUM BROMIDE OR POLYBROMIDES. THE ELECTROLYTE IS THUS AT LEAST SUPERFICIALLY STABLE AGAINST METALLIC LITHIUM, WHICH WOULD BE EXPECTED TO FORM ...

SPIRE CORPORATION PROPOSES TO DEVELOP AN OPTICAL BAFFLE MATERIAL THAT IS METALLIC, LIGHT ABSORBING, RADIATION-HARDENED AND DURABLE. USING A SPIRE DEVELOPED PROCESS, INITIAL EXPERIMENTS HAVE DEMONSTRATED THAT A STRUCTURED BE SPUTTERED LAYER CAN BE DEPOSITED ON PROPERLY PREPARED BE SUBSTATES. THE STRUCTURE IS IN THE FORM OF LIGHT ABSORBING SPIRES WITH HIGH ASPECT RATIOS. OPTIMIZATION OF THE PROCESS ...

CONVENTIONAL ULTRASONIC WELDING BY THROUGH-TRANSMISSION DOES NOT WORK WELL WITH THERMOPLASTIC COMPOSITES BECAUSE THE FIBERS SCATTER THE SOUND WAVES. A NEW METHOD IS PROPOSED WHICH FOCUSES THE ENERGY AT THE SURFACES TO BE JOINED. THE METHOD HAS BEEN SHOWN TO BE EFFECTIVE IN WELDING OTHER MATERIALS THAT ARE DIFFICULT TO WELD BY THROUGH-TRANSMISSION. THE PROGRAM WILL DEVELOP AND ADAPT THE METHOD FOR ...

THE TRAINING TASK SELECTION PROCESS IS AN IMPORTANT ELEMENT OF TRAINING PROGRAM ANALYSIS. CURRENT TASK SELECTION METHODOLOGY IS OFTEN INADEQUATE BECAUSE IT DEPENDS ON SUBJECTIVE INPUT, IS TIMECONSUMING IF CONSCIENTIOUSLY APPLIED, AND FAILS TO INCORPORATE RELEVANT TASK INFORMATION AND EXPERTISE. AN EXPERT SYSTEM DECISIONAIDING DEVICE WHICH WOULD AUTOMATE THE TASK SELECTION PROCESS WOULD ELIMINATE S ...

We propose to develop a generic modular microanalytical system which will integrate sample workup, separation and detection on a chip. It is the ultimate goal to provide chip-based assays dedicated to a predetermined set of analytes. This analyzer will replace more expensive and complex gas chromatographic and mass spectroscopic instruments in numerous applications in the field and laboratory. ...

This Small Business Innovation Research Phase I project will fabricate an array of gas-sensing elements from pulsed-laser deposited (PLD) metal oxide thin films on silicon wafers, which will be integrated with fiberoptics and a digital signal processor (DSP) for device operation, readout, and signal conditioning. The developed sensor instrument that can be used as a subsystem for combustion contr ...

EVERY US LAUNCH SYSTEM DEVELOPED TO DATE HAS ASSUMED THE NEED FOR EXTREME RELIABILITY AND MAXIMUM OBTAINABLE PERFORMANCE IN THE PRIMARY COMPONENTS OF THE STRUCTURE AND PROPULSION SYSTEM. THIS APPROACH STRETCHES THE LIMITS OF AVAILABLE TECHNOLOGY, AND HAS REPEATEDLY RESULTED IN LAUNCH SYSTEMS WHICH CAN NOT PUT MATERIAL INTO EARTH ORBIT AT AN ACCEPTABLE COST. THE SPACE SYSTEM DESIGN COMMUNITY HAS DE ...
