Abstract: A device for analyzing plasma enclosed in a chamber. The device has a lens array which has a plurality of lens array lenses. The lens array lenses are located in a position so that the line of sight for each lens array lens intersects one another at a single point in front of the lens array. Each lens array lens is also located in a position so that each lens array lens is focused near a rear wall of the chamber. Behind each lens array lens is a cable having a first end and a second end. The first end of the cable is located in a position to receive emission elements through the lens array lens. A collimating lens is located at the second end of the cable to couple the emission elements from the second end of the cable through a wavelength selective element. A recording device is located in a position to record the emission elements through the wavelength selective element.

Abstract: An efficient, lightweight, and relatively inexpensive photolysis system based on a short-arc Hg arc lamp provides a simple and accurate method for measurement of ambient NO2. High time resolution is achieved by minimizing inlet and photolysis cell residence times and matching NO and NO2 sample paths, and data reduction is greatly simplified relative to conventional photolysis designs.

Abstract: A cloud radar apparatus is mounted on a portable containerized unit, a number of which may be located at various positions throughout the planet. Cloud radar data from each unit are periodically measured and stored and made available to researchers, upon request, through the Internet or other network. The system comprises two computers operating on different operating systems. A first computer uses a first operating system which allows it to readily interface with various radar equipment using an IEEE 488 interface or the like, to monitor the health of the equipment and operate the equipment. A second computer system uses a second operating system in a multi-user mode which allows it to readily access and manipulate data files and transfer data over the network. Communication between the two computers is achieved by allowing the first computer to log into the second computer as one of the multiple users. The first computer may upload data to the second computer using a FTP protocol or the like.

Abstract: An SOI substrate and method of forming is described incorporating the steps of implanting oxygen under two conditions and performing two high temperature anneals at temperatures above 1250.degree. C. and above 1300.degree. C., respectively, at two respective oxygen concentrations. The invention overcomes the problem of high SOI substrate fabrication cost due to ion implant time and of getting high quality buried oxide (BOX) layers below a thin layer of single crystal silicon.

Abstract: A polarimetric Doppler weather radar system which allows measurement of linear orthogonal polarimetric variables without a switch by using simultaneous transmission of horizontally and vertically polarized waves. This is accomplished by splitting the transmitted power into two waveguides and combining them with an orthomode coupler at the antenna feed. Thus, in general the transmitted polarization is elliptical but with equal amount of power in horizontal and vertical polarization. On reception, the power is divided, at the orthomode coupler, into linear horizontal and vertical components. These components are processed and combined to yield Doppler and polarimetric information about storm structure.

Abstract: A method of remote sensing of water surfaces using laser beams of slightly differing frequencies. Laser radiation scattered from the water surface is collected and processed to determine the surface gravity wave and capillary wave spectrum and surface currents. Maps may be constructed using either land-based or airborne .increment.k-lidar stations.

Abstract: Implantation of a Group V ion species (e.g., phosphorus or arsenic) into an In-based Group III-V compound semiconductor (e.g., InP, InGaAs) followed by implantation of Be ions produces a shallow p-type surface layer and avoids significant in-diffusion of the dopant species. High carrier concentrations and activation efficiences are attained. The technique has application in the fabrication of FETs, APDs and ohmic contacts.

Abstract: The continuous NITROX mixer is a pre-calibrated, continuous flow, gas mix system and a method which combines pure oxygen and air at atmospheric pressure, to create a final mixture of predetermined composition. Constituent gases are regulated to the same pressure and temperature before oxygen is metered through precision micro-metering valves. The system proportions the amounts of each gas and delivers the final mixture to a common mixing chamber. Delivery pressure can be adjusted up to 3000 PSI, making the system suitable for filling SCUBA or storage cylinders.

Abstract: A modified sulfur cement formulation, comprising the polymeric reaction puct of sulfur with a cyclopentadiene oligomer-dicyclopentadiene containing modifier in which the cyclopentadiene oligomer content of said modifier is at least 37 wt. %, the sulfur cement product having a softening point ranging up to 116.degree. C.

Abstract: A universal jig fixture for tree castings includes longitudinally spaced port blocks mounted on a base structure, the support blocks having top openings with converging, sloping sides that engage similarly shaped sides on the runner of the casting, and hold down clamps for pressing the runner down on the support blocks. The casting is longitudinally located by a stop engaging a sprue cup of the casting or an end stop on the support block. The sprue cup includes a spring finger cup, and the hold down clamp can be fluid actuated. Lateral and vertical location of the casting by the support blocks; longitudinal location of the casting is by the sprue cup stop or the end stop.

Abstract: In the center of the bowling ball a three-way valve has been mounted and iating from this, three tubes closed at one end, one of the tubes lying substantially in the plane containing the line of throw while the other two are laterally directed on either side of said plane. The system of tubes and valve contains a quantity of mercury substantially equivalent to the capacity of one tube, and the mercury may by means of the three-way valve be transferred from the central tube into one or the other side tube and thereby the center of gravity shifted to one side. The three-way valve is controllable by means of a stem, from the surface of the ball. In an alternative embodiment all three tubes lie in the plane containing the line of throw.
