Title: Method and apparatus for transmitting picture data, processing pictures and recording medium therefor
Inventor: SUZUOKI MASAKAZU
IPC: H04N21/236
Filed: 1997-09-16
Abstract: A data processing system wherein picture data in  which  there is  allocated  a  value  representing transparency as a pixel value is transmitted after being compressed in terms of picture data corresponding to a pre-set pre-determined size of a picture area as a unit. Ancillary data  specifying whether  each pixel  of  the original  picture  data  of  the  picture  data  unit  is transparent or opaque is transmitted in correlation with the compressed picture data as the unit.  On expansion of the compressed picture data, a pixel set as a transparent pixel by the ancillary data is compulsorily set as a transparent pixel without regard to the expanded picture data.

Title: An error-correcting decoder and decoding method
Inventor: FUJITA HACHIRO
IPC: H03M13/29
Filed: 1997-09-30
Abstract: In an error-correcting decoder, in which an input digital signal including reliability information is decoded by using a Viterbi algorithm as a first decoding process and a final decoded result is obtained by block-code decoding as a second decoding process, a flag signal is added to a location where a value of reliability of path metric determined by the Viterbi algorithm is lower than a threshold, as an original flagged location. A flag signal adding unit continuously adds flag signals to locations, from the original flagged location to locations preceding the originally flagged location, after back tracing. The flagged locations are then regarded as erasure locations in the block-code decoding process.

Title: Cycloaddition functional polymers from (vinyl)polystyrene
Inventor: DARLING GRAHAM D
IPC: C08F8/00
Filed: 1997-11-28
Abstract: We describe a convenient route towards resins of crosslinked polystyrene bearinglarge numbers of carboxylic acid or anhydride, imide, acyl halide, or perhaloalkyl functional groups. These result from Diels-Alder reactions involving the site-isolated, residual vinylaromatic units in divinylbenzene-rich copolymers (including commercial products). As shown by FT IR, solid-phase NMR, titration and elemental analysis, up to two moles of a good dienophile such as maleic anhydride bind to polymer beads byconsecutive Diels-Alder/Ene reactions (Wagner-Jauregg mechanism), while adducts are also possible from electron-poor dienes like hexachlorocyclopentadiene. Afterwards, the new functional groups themselves prove accessible towards further modification. Optionally, the porous bead substrates can first be loaded with magnetic iron oxide to yield magnetically separable functional polymers.

Title: System and process for applying ammonia to soil
Inventor: HENDERSON GRAEME W
IPC: A01C23/02
Filed: 1998-02-18
Abstract: The present invention is generally directed to a system and to a process for dispensing a volatile liquid fertilizer and particularly ammonia  into  a  field.   The ammonia is placed in a vessel under sufficient pressure to maintain a substantial portion of the ammonia in a liquid form.  From the pressurized vessel, the ammonia is fed to a distribution manifold where it is ultimately injected into a soil through a plurality of dispensing tubes.  According to the present invention,  a constant pressure flow rate control  device  is  placed  at  each  dispensing  tube  for metering  the  amount  of  ammonia  fed  to  the  soil.    In particular,  the flow control devices allow ammonia to be dispensed from the system while maintaining sufficient back pressure within the distribution manifold to maintain the ammonia in a liquid form.   By preventing vaporization of the  ammonia  within  the  system,  uniform  and  accurately controlled flow rates can be dispensed from the dispensing tubes.

Title: Linearized digital automatic gain control
Inventor: WILSON NATHANIEL B
IPC: H03G3/20
Filed: 1996-09-16
Abstract: The present invention provides linear, digital automatic gain control (AGC) in a radio. A  received signal is demodulated to provide I and Q digital baseband signals. A received signal strength indication is determined from these signals and the resulting digital signal is adjusted to provide a logarithmic response (205). This signal is then integrated (210) to provide a digital receive AGC adjust signal. For the transmit AGC adjust, the digital receive AGC adjust signal is filtered (215) and then summed (270) with a scaled (260) closed loop power control command (265). The closed loop power control commands (265) are ignored (220) if they would result in increasing the transmit gain beyond the amplifier's designed maximum output.  The outputs of the transmit and receive AGC  amplifiers are linearized by transmit and receive linearizers, (225) and (240) respectively, which pre-distort the digital AGC adjust signals prior to digital to analog conversion (230) and (245).

IPC: B65G19/02
Filed: 1998-06-17
Abstract: A conveyor is provided for conveying cantilevered loads on wheeled carriages. The frame of the conveyor includes carriage roller support surfaces, which support the weight of the carriage and the load and guide the carriage along the conveyor. There is a belt along the frame which drives the carriages. Since the belt does not support the weight of the carriage, the force between the carriage and the belt need only be sufficient to drive the load. This reduces the energy used by the conveyor, reduces the wear on the conveyor, and reduces jostling of the products being conveyed.
