Patent CA-2040562-A1 (CA)
Inventor: KAWATA TOSHIYUKI
IPC: H04N1/393
Filed: 1991-04-16
Abstract: A half tone image processing circuit in which samples of an image signal are compared with elements of a dither matrix to generate a binary image signal, and including a scale reduction circuit for canceling predetermined bits from the binary image signal to effect a reduction in size of an image produced in accordance with the binary image signal.  A dither generation circuit sequentially outputs the dither elements in response to a clock signal.  During scale reduction, the incrementing of the dither generation circuit is halted when samples are received that correspond to the bits to be canceled, so as to avoid picture quality degradation by maintaining continuity of the dither generation pattern.

Title: Conductive sensors and their use in diagnostic assays
Inventor: MUSHO MATTHEW K
IPC: G01N27/12
Filed: 1991-06-04
Abstract: Abstract of the Disclosure A conductive sensor and its use in a diagnostic assay are disclosed. The miniaturized conductive sensor, utilizing a conducting polymer, is used in a diagnostic device to determine the presence or concentration of a predetermined analyte in a liquid test sample, wherein the predetermined analyte, like glucose, is assayed by an oxidase interaction. The interaction between the oxidase and a small amount of the predetermined analyte in the test sample generates, either directly or indirectly, a dopant compound in a reaction zone of the conductive sensor. The dopant compound then migrates to the detection zone of the conductive sensor of the diagnostic device to oxidize the conducting polymer and convert the conducting polymer from an insulating form to a conducting form. The resulting increase in conductivity of the conducting polymer is measured, then the conductivity increase is correlated to the concentration of the predetermined analyte in the test sample.

Title: Encoder with fiber optic collimator/aperture
Inventor: SWENSON RICHARD I JR
IPC: G02B6/04
Filed: 1992-02-14
Abstract: -i-Abstract of the Disclosure A collimator/aperture, in an absolute encoder, produces a line of light to illuminate the encoder's code wheel.  The collimator employs a bundle of fiber optics to receive an intense and generally cylindrical beam of laser light.  The opposing end of the fibers are spread in a fan and clamped between carefully dimensioned clamping surfaces to produce a line of light one fiber thick.  The collimator/aperture avoids the wasted energy associated with a slit mask.  The fiber optics are held parallel near their light emitting ends and the ends are polished square to the axis of the fibers to provide a high degree of collimation.  Fibers with low numerical aperture further improve the collimation.

Title: Diffuse secondary emission electron shower
Inventor: BENVENISTE VICTOR M
IPC: H01J37/317
Filed: 1992-06-30
Abstract: ABSTRACT   An ion implantation featuring an improved beam neutralizer. A cylindrical electron source encircles the ion beam at a location just before the ion beam enters an implantation chamber. Regularly spaced cavities in the electron sourcecontain wire filaments which are energized to emit electrons. The electrons are accelerated through the region of the ion beam and impact an inwardly facing wall of the cylindrical electron support. This causes low-energy electron emissions which neutralize the ion beam. Performance of the beam neutralizer is enhanced by injecting an ionizable gas into the region between the electron emitting surface and the ion beam.

Abstract: A stainless steel tank has a hinged cover which closes over a cylindrical drum which is rotatably mounted within the tank.  The drum has a stiff support structure with an inlet end plate and a discharge end plate and a plurality of linear support members extending between and rigidly fastened to the two end plates.  A helical auger is welded to and supported by the support members and is positioned within the drum by a central core tube.  The auger and core tube are not connected to the inlet end plate leaving an unobstructed open-throat which allows the free flow of food product into the drum.  A perforated cylinder of screen material surrounds the drum and retains food product therein.  An infeed flight attachment extends from the auger to the inlet end plate and has a curved portion which extends beneath the water level to avoid contact with the food product above the water level.  The inlet opening to the drum may be of larger diameter than the core tube allowing the introduction of very wide food product into the drum.
