Patent number: 5787146Abstract: An X-ray imaging system utilizing diffractive X-ray examination is utilized which includes an interrogating X-ray path from a conventional broad band X-ray source having a standard emission point. X-rays from the X-ray source impinge on a toric monochronometer having monochromatic Bragg X-ray diffraction occurring resulting in monochromatic X-ray diffraction. X-rays exiting the slit aperture stop expand and form a scanning beam and pass through the specimen (usually soft tissue) being examined. In passing through the specimen, the X-rays receive image information by absorption, critical angle scattering, and, refraction, dependent upon the specimen, structure. The X-rays are then incident on a toric detection crystal where monochromatic Bragg X-ray diffraction again occurs leaving the image revealed by absorption, critical angle scattering, and, refraction which occurred in the specimen.Type: GrantFiled: October 18, 1996Date of Patent: July 28, 1998Assignee: SPAD Technologies, Inc.Inventor: Robert H.

Patent number: 5474299Abstract: The invention provides a golf swing trainer for use by a developing golfer. The trainer includes a rotor that rotates about a rotational axis. When using the trainer, the golfer connects himself or the golf club shaft to the rotor at a point near his hands. The golfer then takes practice swings while linked to the rotor. According to one aspect of the invention, the rotor is flexible so that deviations in the golfer's swing from the ideal path causes flexure of the rotor. This in turn causes noticeable flexure and vibration in the rotor, which clearly indicates the error to the golfer so that he may correct his motion on subsequent swings. According to another aspect of the invention, the rotational inertia of the rotor about the axis is less, and in preferred embodiments much less, than that of the swung club about the same axis. This ensures that the inertia of the rotor will not obscure the natural feel of the proper swing. Rapid development of the golfer's skill is improved with use of the trainer.Type: GrantFiled: August 3, 1993Date of Patent: December 12, 1995Inventor: Edward A. Romano

Patent number: 5298437Abstract: A method for fabricating a diode, for example, for use in a Schottky clamped transistor, which as a process step disposes a layer of oxide between the substrate and the overlying layer of polysilicon which must ultimately be etched away. The oxide layer permits use of an end point dry etch process which in turn allows greater miniaturization of the circuit over wet etch processes. Use of the end point process made feasible by the oxide layer also prevents overetch of the silicon material. As a result, a more ideal metal silicide anode-to-substrate Schottky barrier is formed with corresponding improvements in the diode ideality factor. In addition the oxide layer eliminates Schottky mask alignment problems and further improves diode performance characteristics by elimination of parasitic diodes. The process can be implemented with minimal deviation from other core processes used to fabricate similar circuits.Type: GrantFiled: July 28, 1992Date of Patent: March 29, 1994Assignee: National Semiconductor CorporationInventors: Brian McFarlane, Frank Marazita, John E.
