Title: Insert molding for non-rigid encapsulated components
Inventor: DICKIE ROBERT GERALD
IPC: B29C33/12
Filed: 1991-07-01
Abstract: An injection molding technique is disclosed in which non-rigid or flexible components intended to be encapsulated within an interior of an injection molded product are held in postion in an interior of a mold cavity (11) during the injection operation by thin, rigid forks or blades (23, 24, 25) with surfaces interior to mold cavity contoured to mate with and capture the non-rigid, flexible component (17, 19). Such forks or blades can be retracted prior to the final packing portion of the molding cycle to allow plastic flow into the void left by the retracted blades, or the blades can be retracted after the end of the injection cycles and voids left in the molded product. Portions of the encapsulated components themselves can be fashioned to capture and hold portions of other encapsulated components during the injection process.

Abstract: A direct-writing electron beam is used for defining features in a resist layer and hence ultimately in an underlying workpiece, such as in a phase-shifting mask substrate or a semiconductor integrated circuit wafer. The resist layer is located on a top major surface of the workpiece. In a specific embodiment, the resist layer is located underneath a protective layer of polyvinyl alcohol ("PVA"); and a grounded conductive layer, such as a conductive organic layer, is located on the protective layer. After exposing the top major surface of the resulting structure to the direct-writing electron beam, the following steps are performed: (1) a plasma etching completely removes the entire thickness of the conductive layer as well as a small fraction of the thickness of the PVA layer; (2) the PVA layer is then completely removed by dissolving it in water; (3) another plasma etching removes a small fraction of the thickness of the resist layer, including any unwanted residues; and (4) the resist layer is developed.

Title: High power, high gain, low noise, two-stage optical amplifiers
Inventor: DIGIOVANNI DAVID J
IPC: H01S3/07
Filed: 1994-07-12
Abstract: Abstract of the Disclosure High output power, high gain, and low noise are achieved in a two-stage optical amplifier, suitable for use as a repeater for a long haul lightwave communication system, in accordance with the principles of the invention, by employing a first amplifying stage having a signal gain sufficiently small to prevent self-saturation by amplified stimulated emission (ASE) that uses counter-propagating pump light to cause maximum inversion of the first stage amplifying medium. In an illustrative embodiment of the invention, EDFAs are used in each of two amplifying stages. The length of the EDFA in the first stage is short enough to ensure nearly complete inversion of the EDFA from pump light that counter-propagates with the signal. The counter-propagating pump light allows the invention to advantageously avoid the significant noise figure penalty from the input loss associated with co-propagating pump light. And, noise figure is improved becausecomplete inversion is achieved throughout the EDFA, and, at the input where the noise figure is most sensitive to inversion. The short length also eliminates self-saturation of the EDFA from ASE which degrades the noise figure. However, the length, and hence the gain, of the EDFA in the first stage is long enough to provide sufficient gain so that the noise figure of the two-stage amplifier, as a whole, is determined primarily by that of the first stage. A second EDFA in the second stage of the amplifier may then be configured using co-propagating or counter-propagating pump light for additional signal amplification to provide the required output power and gain for long haul lightwave systems. Other aspects of illustrative embodiments of the invention include the use of passive optical elements including filters, isolators, and attenuators. (FIG. 1)

IPC: F25J1/02
Filed: 1994-08-04
Abstract: PROCESS TO INCREASE NATURAL GAS METHANE CONTENT                 Abstract of the Invention The present invention is directed to a process for purifying natural gas to provide a liquified natural gas product which is substantially pure methane.  In the process, a natural gas feed stream is introduced into indirect countercurrent heat exchange in a first heat exchanger to cool the natural gas to below the dew point of ethane and higher hydrocarbons so as to separate the feed stream into a gas which is substantially pure methane and liquid which contains the ethane and higher hydrocarbons.  The liquid/gas mixture is transferred to a separator where the gas occupies the head space of the separator and the liquid occupies the bottom of the separator.  A gas friction is removed frm the top of the separator and is introduced into countercurrent heat exchange with liquid nitrogen in a second heat exchanger so as to liquefy the substantially pure methane gas. Liquid nitrogen is introduced into a third heat exchanger where the liquid nitrogen is mixed with a recycled portion of nitrogen vapor is mixed with a recycled portion of nitrogen vapor exiting from the second heat exchanger to provide a liquid nitrogen feed stream for the second heat exchanger.  The nitrogen vapor exiting from the second heat exchanger is divided into a recycle portion for introduction into the third heat exchanger and a heat exchange portion for introduction into countercurrent heat exchange with the natural gas feed stream in the first heat exchanger.  A liquid fraction containing C2 and higher hydrocarbons is removed from the bottom of the separator.  The liquid fraction removed from the bottom of the separator is introduced into indirect countercurrent heat exchange with the natural gas feed stream in the first heat exchanger.

Abstract: 17. DISCLOSURE IMPROVED LOG SCANNING A log scanning system applies circumferentially spaced, traverse scans along the length of the log to provide a longitudinal density scan for each of the scans made. Each scan is made up of rows of density dependent pixels sensed by specific detector (scan line) and columns of density dependent pixels sensed by adjacent detectors arranged transversely of the log. The signals generated along each row to are filtered to produce a clean signal scan line and each clean scan line is processed to determine positive peaks. The positive peaks are plotted to form an image and adjacent peaks in adjacent rows and columns are joined to provide a spine image depicting spines of detected knots in each scan. Knot shapes are then defined by reprocessing each scan along the rows or scan lines to determine the knot boundaries on each side of each of the spine lines based on pixels displaying a selected minimum density and these shapes applied to the spine image to provide a reconstructed scan. The longitudinal axis of the log is determined and applied to the reconstructed scans to define the roots or inner ends of the knots. The reconstructed scans are then used to define the same knot in each of the reconstructed scans and then to generate a three-dimensional image of the log which may then be used by a sawing program to determine how the log should be sawed.
