Abstract: ABSTRACT OF THE DISCLOSURE    Disclosed is a particle beam lithography system (10) having a workpiece loading/unloading position to one side of a particle beam (32) and beam column (12) where a workpiece (14), to be processed, is placed in a vacuum chuck (100) to eliminate any irregularity or warpage of the workpiece (14).  At this same position, the workpiece (14) is oriented and fixed at a preselected distance from a standard by gap setting means (162, 162b).  This distance correlates with a preselected gap (G) between a seal apparatus (16) and the workpiece (14) during workpiece processing.  The workpiece (14) and chuck (100) are then moved beneath the seal apparatus (16) and beam column (12) for workpiece processing.  After processing, the workpiece (14) and chuck (100) are returned to the loading/unloading position to be removed from the lithography system (10).  An interface plate (64) is moved from the loading/unloading position to the workpiece processing position by an X-Y stage (50) and a workpiece transport system (130) is provided to transport the workpieces (14) to and from the lithography system (10) to appropriate cassettes (132,134).

Abstract: A method for diagnosing Alzheimer Disease or a predisposition to develop  Alheimer Disease in an individual, by determining the presence of an alteration in the normal base sequence of the 24 base pairs appearing at the end of the APC coding sequence of the preAPC gene, or in the normal base sequence of the corresponding mRNA, in the DNA or RNA  or such individual. The method detects the presence of a frameshift mutation in the preAPC gene postulated to result in the synthesis of the APC protein.  Accumulation of APC protein in the brain is a  phenomen of  Alzheimer Disease.  A variety of nucleic acid hybridization techniques are applicable to the determination of an alteration in the preAPC gene sequence of interest.

Abstract: ABSTRACT      Non-woven fabrics produced from spunbonded web of the thermally bonded type suitable for use in folding window blinds are disclosed.  To provide an opaque fabric with a weave-like finish a metalized blackout film and the spunbonded web substrate are laminated together while simultaneously embossing the substrate.  Non-opaque fabrics may be made by using a film without metalization.  Binder material is added to provide corrosion protection for the metalized film and additional bonding to the substrate . Difficulties in embossing this type of web are overcome by using steel embossing rollers and narrow widths of web. Using this basic process opaque fabrics may be made without embossing by creating a temporary bond between the layers with the surface tension of water, or non-opaque fabric made by not adding any film in the embossing step.

Title: Clock recovery circuit
Inventor: THOMAS ROBERT M
IPC: H03K5/135
Filed: 1989-09-20
Granted: 1992-03-31
Abstract: CLOCK RECOVERY CIRCUIT A clock recovery circuit includes a resonant circuit which is driven into oscillation at a clock frequency by binary 1 pulses in a data signal supplied thereto, a clock signal being derived from the resonant circuit via a buffer and a limiting amplifier. The resonant circuit has a high Q to accommodate long sequences of binary 0s during which it is not driven. In order to prevent over-driving when the data signal has a high density of binary 1s, a level detector detects when the oscillation amplitude exceeds a threshold level, whereupon a flip-flop is set to control a gate to inhibit driving of the resonant circuit until its oscillation amplitude has decayed. The flip-flop is clocked by the data signal to operate in synchronism with the incoming data, and may be followed by a second similarly clocked flip-flop to avoid potential errors.

Abstract: Vapor deposition of doped silica in a reaction chamber on a rotating supporting surface, in the manufacture of a preform for the drawing of an optical fiber, is accompanied by the continuous admixture of deuterium with a flow of carrier gas, specifically oxygen, by which the reactants are transported to the reaction chamber. An isotopic substitution of deuterium for the hydrogen of hydroxyl groups in the reaction products shifts the major absorption peaks to wavelengths outside the minimum-attenuation range of 0.7 to 1.6 mu  used for fiber-optical signaling. The proper ratio of deuterium to carrier gas is maintained with the aid of a mixer having two compartments separated by a perforated diaphragm or a thin metallic foil, one compartment being connected to a deuterium tank while the other communicates with a conduit through which the vapors entrained by the carrier gas pass to the reaction chamber.
