Patent CA-2037544-A1 (CA)
Title: Apparatus for encoding digital data
Inventor: AKAGIRI KENZO
IPC: H04B1/66
Filed: 1991-03-05
Abstract: APPARATUS FOR ENCODING DIGITAL DATA     ABSTRACT OF THE DISCLOSURE      Apparatus for efficiently encoding a digital signal includes an arrangement (41, 42) for dividing the signal into a number of frequency band signals.  The frequency band signals are segmented into blocks and the  blocks  are  orthogonally  transformed  (43,  44,  45)  to  form coefficient data.   The coefficient data is then quantized (58).   A circuit (50) detects whether at least the lowest frequency one of the frequency band signals contains a transient.  If so, a control circuit (57;  102; 100) controls processing of at least the lowest frequency band  signal  so as  to  reduce  the  perceptibility  of noise  in  the processed signal.  The control circuit may be operative, in the event of detection of a transient, to increase the number of bits used for quantizing at least the lowest frequency band signal, to reduce the block size of at least the lowest frequency band signal, and/or to reduce the level of at least the lowest frequency band signal.

Abstract: OPTICAL ARTICLE FOR MULTICOLOR IMAGING      Abstract of the Disclosure An optical article capable of modulating the reflection of polarized monochromatic electromagnetic radiation is disclosed comprising a reflective metal layer having a thickness of less than 0.5 µm, means acting as a support for directing polarized electromagnetic radiation to the reflective metal layer, a dielectric layer interposed between the support and the reflective metal layer having a refractive index less than that of the support and a thickness in the range of from 0.1 to 10 times the wavelength of electromagnetic radiation directed toward the reflective metal layer, an electrooptic medium that exhibits a refractive index which is a function of an applied electrical potential, and a counter electrode.         The optical article is characterized in that it is capable of modulating the reflection of polarized monochromatic electromagnetic radiation from differing wavelength sources to produce a multicolor image.  To this end, the reflective metal layer is divided into a plurality of electrically isolated zones each intended to be addressed by electromagnetic radiation from a different wavelength source, the dielectric layer exhibits a different thickness adjacent each of the zones, the counter electrode is divided into electrically isolated zones, and the article additionally includes means for focusing reflected polarized electromagnetic radiation from each of the zones on a common target area.

Patent CA-2039060-A1 (CA)
IPC: G02F1/35
Filed: 1991-03-26
Abstract: Optically nonlinear device elements such as directional couplers, switches, frequency stabilizers, optical parametric devices and modulators use as an optically nonlinear element a cross-linked triazine polymer containing a covalently bonded optically nonlinear dye moiety. A specific cross-linked triazine with this dye moiety may be made by cyclotrimerizing a p-(N,N-bis(4'-cyanatobenzyl)amino)-p'-(2,2-dicyanovinyl)azobenzene monomer. During polycyclotrimerization or cure, theelement is subjected to a poling voltage which aligns the dipoles of the dye moiety to give a large useful nonlinear susceptibility.

Title: Process and equipment for casting silicon blocks of columnar structure as the base material for solar cells
Inventor: PRIEWASSER GEORG
IPC: H01L31/04
Filed: 1991-06-12
Abstract: ABSTRACT OF THE DISCLOSURE            By means of the process and by means of the ap-paratus, fused silicon is produced continuously, or in phases, and zonally cast into a mold in which it is caused to solidify zonally.  The temperature conditions in the solidification zone are controlled with the aid of a movable heating zone, by means of which the crystallization front is adjusted to the rising level that fills up the mold, this level being in turn controlled by the fusion rate of the silicon.  Polycrystalline silicon blocks can be obtained in which, because of the flat shape of the crystallization front, the columnar single-crystal domains within the blocks extend almost vertically and which represent an excellent solar cell base material having high diffusion lengths and lifetimes of the minority charge carriers, from which solar cells of correspondingly high efficiencies can be produced.

Abstract: A system and method for managing the nonvolatile memory capacity of individual workstations within a data processing network having a multiplicity of workstations with resident nonvolatile memory devices.  In the context the embodying  network,  the  invention  provides  for  a selective querying of workstations to determine unused disk  capacity,  a  comparison  of  such  capacity  to  a threshold defined for the respective workstation, and the generation of an event message indicating sub-threshold capacity.   The  event  is  subject  to  local  or  network logging,  and  can  include  information  identifying  the workstation and its disk capacity status.  A refinement of the invention contemplates the reallocation of disk capacity   within   the   network   to   avoid premature termination of programs executing on a workstation upon the  finding of  a  sub-threshold  capacity  in  the workstation.
