Abstract:
The present invention is for a high-speed, commercial-scale means for deposition of films and coatings on a substrate. The PIBAD (pulsed ion beam assisted deposition) processes [Fig. 4] allow notonly deposition, but also special modes of post-deposition treatment of films and coatings, including annealing, melting and regrowth [Fig. 4A], shock wave treatment, and high-pressure plasma redeposition [Fig. 4B] all of which can alter the mechanical, cohesive, and corrosive properties of the final product. In one embodiment of the invention the power system comprises a motor (5) which drives an alternator (10). The alternator delivers a signal to a pulse compression system (15) which has two subsystems, a 1 mu s pulse compressor (12), and a pulse forming line (14). The pulse compression system (15) provides pulses to a linear inductive voltage adder (LIVA)(20) which delivers the pulses to the ion beam source (25).
Abstract:
A method and apparatus for treating material surfaces (13) using a repetitively pulsed ion beam (11). In particular, the treatment is tailored by adjusting treatment parameters of a pulsed ion beam (11) to a duration less than or equal to 1000 ns and a repetition rate of less than 1 Hz.
Abstract:
An inflatable cushion assembly for use with an inflator comprises an inflatable cushion having an inner surface, outer surface, and at least one protrusion extending from one of the inner or outer surfaces. The inflatable cushion defines an opening between the inner surface and the outer surface for receiving the inflator. An attachment member (36) contacts the one of the inner or outer surfaces adjacent the opening and includes a groove (40) for receiving the protrusion, the attachment member (36) securing the inflator within the opening.
Abstract:
A method of producing carbon materials for use as electrodes in rechargeable batteries. Electrodes prepared from these carbon materials exhibit intercalation efficiencies of APPROX 80 % for lithium, low irreversible loss of lithium, long cycle life, are capable of sustaining a high rate of discharge and are cheap and easy to manufacture. The method comprises a novel two-step stabilization process in which polymeric precursor materials are stabilized by first heating in an inert atmosphere and subsequently heating in air. During the stabilization process, the polymeric precursor material can be agitated to reduce particle fusion and promote mass transfer of oxygen and water vapor. The stabilized, polymeric precursor materials can then be converted to a synthetic carbon, suitable for fabricating electrodes for use in rechargeable batteries, by heating to a high temperature in a flowing inert atmosphere.
Abstract:
An electrically written memory element utilizing the motion of protons within a dielectric layer surrounded by layers on either side to confine the protons within the dielectric layer with electrode means attached to the surrounding layers to change the spatial position of the protons within the dielectric layer. The device is preferably constructed as a silicon-silicon dioxide-silicon layered structure with the protons being introduced to the structure laterally through the exposed edges of the silicon dioxide layer during a high temperature anneal in an atmosphere containing hydrogen gas. The device operates at low power, is preferably nonvolatile, is radiation tolerant, and is compatible with convention silicon MOS processing for integration with other microelectronic elements on the same silicon substrate. With the addition of an optically active layer, the memory element becomes an electrically written, optically read optical memory element.
Abstract:
A system where application programs can be programmed and accessed with input/output device independent, generic functional commands. A shared memory structure (200) allows the translation of device specific commands to device independent, generic functional commands. The system provides a multi-dimensional user oriented synthetic environment with a craft (400) surrounding the user to provide a visual reference and motion parallax cues enabling the user to better appreciate distances and directions within the synthetic environment. The system provides the display of the craft in close proximity to the user's point of perspective without substantially degrading the image resolution of the displayed environment.
Abstract:
An infinitely variable transmission is capable of operating between a maximum speed in one direction and a minimum speed in an opposite direction, including a zero output angular velocity, while being supplied with energy at a constant angular velocity. Input energy is divided between a first power path carrying an orbital set of elements (24) and a second path that includes a variable speed adjustment mechanism (40). The second power path also connects with the orbital set of elements (24) in such a way as to vary the rate of angular rotation thereof. The combined effects of power from the first and second power paths are combined and delivered to an output element (60) by the orbital element set (24). The transmission can be designed to operate over a preselected ratio of forward to reverse output speeds.
Abstract:
A method for releasing molecules (guest molecules) from the matrix formed by the structure of another molecule (host molecule) in a controllable manner has been invented. This method has many applications in science and industry. In addition, applications based on such molecular systems may revolutionize significant areas of medicine, in particular the treatment of cancer and of viral infection. Similar effects can also be obtained by controlled fragmentation of a source molecule, where the molecular fragments form the active principle.
Abstract:
A segmented rail linear induction motor (10) has a segmented rail (40) consisting of a plurality of nonferrous electrically conductive segments (44-0, 44-1, 44-2, 44-3, 44-4) aligned along a guideway. The motor further includes a carriage (12) including at least one pair of opposed coils (21, 22) fastened to the carriage (12) for moving the carriage (12). A power source (24) applies an electric current to the coils (21, 22) to induce currents in the conductive surfaces to repel the coils (21, 22) from adjacent edges of the conductive surfaces.
Abstract:
A method and an optical device for bistable storage of optical information, together with reading and erasure of the optical information, using a photoactivated shift in a field dependent phase transition between a metastable or a bias-stabilized ferroelectric (FE) phase and a stable antiferroelectric (AFE) phase in an lead lanthanum zirconate titanate (PLZT). An optical disk (1) contains the PLZT. Writing and erasing of optical information can be accomplished by a light beam (14) normal to the disk (1). Reading of optical information can be accomplished by a light beam (5) at an incidence angle of 15 to 60 degrees to the normal of the disk (1).
