Title: Surface modification of hydrophobic polymer substrate
Inventor: GILLBERG-LAFORCE GUNILLA ELSA
IPC: C08J7/056
Filed: 1997-05-28
Abstract: A method for coating the surface of a substrate composed of a hydrophobic polymer with a hydrophobic vinyl polymer. The method includes preparing a solution of the hydrophobic vinyl polymer in a polar nonaqueous solvent,  such as 1-methyl-1-pyrrolidinone, in which the hydrophobic vinyl polymer is surface-active.  The substrate then is treated with the solution under conditions sufficient to deposit the hydrophobic vinyl polymer on the substrate.   The hydrophobic vinyl polymer may have readily hydrolyzable pendant groups which, upon hydrolysis thereof in an aqueous medium, will result in the formation of a hydrophilic vinyl polymer coating on the substrate.  For example, the hydrophobic vinyl polymer may be poly(vinyl  trifluoroacetate).   Also  provided  are  coated substrates,  in which the substrate  is a  shaped article composed of a hydrophobic polymer. The shaped article may be, for example, a film, fiber, or nonwoven web.

Title: Line width insensitive wafer target detection
Inventor: MARKOYA LOUIS
IPC: H01L21/027
Filed: 1997-09-29
Abstract: An alignment system for use in semiconductor manufacturing that matches pairs of like edges of alignment marks.  Grating type alignment marks are illuminated by a predetermined illumination pattern with the reflected and/or scattered electromagnetic radiation collected by a detector.  Like edges are selected from the collected electromagnetic radiation and matched.  A signal analyzer analyses the matched like edges and obtains alignment information.  The matching of like edges results in relatively process insensitive detection of wafer a alignment marks.  The distance between like edges is substantially less effected by wafer processing.  Wafer alignment marks can thereby be more accurately detected, resulting in improved positioning and alignment accuracies.  This improves and advances the technology use to manufacture semiconductor devices.

Patent CA-2240141-A1 (CA)
Title: Methods and apparatus for providing multi-phase resistance to motion
Inventor: KYSILKA JAMES OTTO
IPC: F41B5/00
Filed: 1998-06-08
Abstract: A multi-phase connector includes an elastic tube and a tether disposed inside the tube. The length of the tether is greater than the length of the unstretched tube but less than the length of the tube if stretched to its elastic limit. As a result, the connector resiliently stretches until the tether becomes taut. When at rest, the elastic tube may be disposed within a housing which provides UV protection. Applications for the connector include exercise apparatus and projectile launching apparatus. A preferred embodiment sling bow has rigid guide tubes mounted to a universal frame which allows both the handle and guide tube assembly to pivot. The elastic thrust tubes are disposed inside the rigid guide tubes and secured to their forward ends with tension adjusters. A  pull-limiting/safety line is disposed inside each elastic tube and is connected to the bow string proximate the rearward end of the elastic tube and to the tension adjuster proximate the forward end of the elastic tube. Sights are mounted on the upper guide tube, and arrow rests are installed between the two guide tubes. A pull knob or pull loop is secured to the bow string center position. When the bow string is pulled back, the arrow will stay aligned with the sights due to the universal pivot feature of the sling bow.  Features of the preferred embodiment include UV degradation protection of the elastic tubes, safety protection for the shooter if an elastic tube should break or become detached from its mounting, over-draw protection, right or left-hand shooting capability, and collapsibility of the sling bow handle parallel to the guide tubes to facilitate storage in a pocket, holster, or backpack.

IPC: H04B1/7113
Filed: 1998-08-05
Abstract: A RAKE receiver (112) includes a plurality of fingers (122,124,126, 128). Each finger includes a demodulator (402) for demodulating a ray of a multipath signal and a time tracking circuit (404) for controlling the time position of the finger in accordance with time position of the ray. A low delay-spread condition is detected and the positions of two adjacent fingers are controlled to prevent convergence of two or more fingers about a common time position. By maintaining finger timing separation, path diversity is exploited by the RAKE receiver even during the low delay-spread condition to improve receiver performance.
