Abstract:
Ion implant apparatus using a drum-type scan wheel holds wafers with a total cone angle less than 60°. A collimated scanned beam of ions, for example H+, is directed along a final beam path which is at an angle of at least 45° to the axis of rotation of the scan wheel. Ions are extracted from a source and accelerated along a linear acceleration path to a high implant energy (more than 500 keV) before scanning or mass analysis. The mass analyzer may be located near the axis of rotation and unwanted ions are directed to an annular beam dump which may be mounted on the scan wheel.
Abstract:
An apparatus and a method of ion implantation using a rotary scan assembly having an axis of rotation and a periphery. A plurality of substrate holders is distributed about the periphery, and the substrate holders are arranged to hold respective planar substrates. Each planar substrate has a respective geometric center on the periphery. A beam line assembly provides a beam of ions for implantation in the planar substrates on the holders. The beam line assembly is arranged to direct said beam along a final beam path.

Abstract:
The embodiment of the invention disclosed herein is directed to a wind instrument made of tubular metal and having an initial straight portion beginning at a mouthpiece receiving end and terminating in a sound-emanating bell portion. The wind instrument is provided with a plurality of piston valves to be manipulated to produce a multitude of different musical notes. A pair of spaced apart tubes is held in a fixed relation relative to one another and to the wind instrument. These tubes have terminating ends extending in a direction opposite that of the mouthpiece receiving end portion. A slide member has a U-shaped end portion which leads into a pair of straight parallel spaced apart portions having open ends fitted over the terminating ends of the tubes and is movable therealong to enable a player to obtain a multitude of different musical notes without manipulation of the piston valves. Lock means is provided between the slide member and the fixed tubes to lock the slide member in a fixed nonmovable position during one instance and to allow release of the slide member for playing of different musical notes during another instance. The sound-emanating bell portion is bent upwardly to allow clearance for movement of the slide member. The mouthpiece receiving end portion is provided with a single slidably adjustable tube portion telescopically inserted therein to provide pitch adjustment for the wind instrument. The singular slidably adjustable tube member is held in a fixed relation by a split-ring clamp associated with the mouthpiece receiving end portion of the wind instrument.

Abstract:
A system for gasifying a carbonaceous feedstock, such as municipal waste, to generate power includes a devolatilization reactor that creates char from the feedstock and a gasifier that creates a product gas from both the char and from volatiles released when devolatilizing the feedstock. The product gas is reacted in a fuel cell to create electrical energy and process heat. The process heat is used to heat the devolatilization reactor and the gasifier. The gasifier comprises a plurality of configurable circuits that can each be tuned to meet the individual needs of the char material being gasified.
