    摘要: A monolithic imager utilizing a plurality of detector cells is formed on a common intrinsic substrate. Backside illumination in the near-IR region generates hole-electron pairs in the intrinsic material which may be depleted throughout its thickness by CCD-range voltages applied by the imager's readout structure to a over-lying, thinly doped epitaxial layer. Minority carriers migrate toward a collection node which is formed in the epitaxial layer (and protrudes into the substrate), accumulating in an inversion layer at the surface of the epitaxial layer. The accumulated charge is advanced to an output diffusion in the epitaxial layer by means of a readout system which provides semi-random addressing of the transfer gate electrodes of the individual detector cells.

    摘要: A device and method for accurately sensing the direction and magnitude of small displacements between two objects, independent of the distance between the objects, utilizing a monochromatic light source and a reflector to produce a light standing wave pattern and a transparent photosensitive detector to detect the number of crests and/or nodes of the light standing wave pattern intercepted.

    摘要: The invention relates to a process that results in a fluoropolymer composition with improved chemical, thermal and color stabilities, and a reduced level of residual surfactants (both fluorosurfactants and non-fluorosurfactants. Such improvements, as indicated by total oxidizable carbon (TOC) and pellet yellowness index (YI), can be accomplished in a cost-effect manner through the use of a dewatering extruder. The dewatering extruder combines several typical unit operations into a single operation, producing solid fluoropolymer having a significantly reduced total oxidizable carbons, a lower yellowness index and minimal amounts of surfactants.
