Granted: 2002-09-17
Abstract: A method and apparatus are provided for recovering and tracking the carrier in a QAM communication system, even under heavy interference conditions.  A subset of fixed points is defined on an ideal constellation pattern for comparison to the data points in a received signal.  The subset includes all of the points intersected by n radii (e.g., the four diagonals) of the constellation pattern.  Additional points along the perimeter of the constellation pattern can also be provided in the subset.  Data points received via a carrier are correlated with the fixed points of the subset in order to generate an error signal indicative of a phase difference between the fixed points of the subset and the received data points correlated therewith.

Title: Multistage plant culture method and multistage plant culture apparatus for use therein
Inventor: IWAI KAZUYA
IPC: A01G31/06
Filed: 1995-03-09
Granted: 2005-08-09
Abstract: A multistage plant culture method and apparatus for carrying out the method are disclosed. Culture beds constituted by rooting medium contained in culture containers (10, 11, 12, 13) and initially containing plant seedlings (17, 18) are moved, in order, from an uppermost level to a lowermost level after the plants have been grown at eac h level for a predetermined period. After cropping, the culture bed at the lowermost level is removed, and a new culture bed containing seedlings (17, 18) is placed at the vacant uppermost level. This sequence is repeated. The culture containers (10, 11, 12, 13) have a predetermined length and are supported on a plurality of support means arranged vertically at different heights. A culture container lift unit includes culture container holding means capable of movement towards or away from the culture containers, and also capable of holding the containers and moving them up or down to facilitate their movement between the different levels. The invention thus enables continuous cropping to be achieved with increased yield and an increased amount of sunlight to reach the plants, particularly at the lower level. The invention also lends itself to automation, to the reduction of any requirement of manual operation, and to large-scale culture.

Title: Two-dimensional modulation for line screen printing
Inventor: VENKATESWAR VADLAMANNATI
IPC: B41J2/52
Filed: 1996-09-18
Granted: 2007-09-25
Abstract: An improved method of line screen printing. Instead of screening the image with only one set of lines, the image is also screened with a second set of lines, which are substantially orthogonal to those of the first set. The screening is accomplished with two types of cells, horizonal cells and vertical cells. The pixels are classified according to their distance from the nearest line in the horizontal cells. This process is repeated with respect to the vertical cells. Different tone curves, which map input pixel values to output pixel values, are associated with different pixel classifications. In general, pixels closer to lines have tone curves that map to higher output values. Because each pixel is in both a horizontal cell and a vertical cell, each pixel has two values from the tone curves. For each pixel, its two tone curve values are combined to obtain a greyscale value for that pixel.

Abstract: Provided is an economical method of solvent extraction of a nickel sulfate solution to purify nickel sulfate, in which the organic phase obtained is prevented from being contaminated with impurities such as sodium and ammonium, and a high-purity nickel sulfate solution is obtained with ease. The method uses a multi-stage, counter-current, organic solvent extraction system composed of at least two extractors as connected in series, and comprises a first extraction step of feeding a crude nickel sulfate solution that contains impurities of essentially sodium and ammonium into a second-stage extractor, followed by processing therein the crude nickel sulfate solution with an organic extractant having been fed into the second-stage extractor from the first-stage extractor, within a pH range falling between 6.5 and 7.0 in a manner of counter-current extraction reaction therebetween to thereby make a part of nickel existing in the crude nickel sulfate solution extracted out into the organic extractant; and a second extraction step of transferring the nickel-containing, organic phase to an organic phase-scrubbing step of scrubbing it to remove sodium and ammonium from the thus-transferred, nickel-containing organic phase, while transferring the crude nickel sulfate solution, which has been processed in the first extraction step and from which a part of nickel has been removed, to the first-stage extractor, followed by further processing therein the thus-transferred crude nickel sulfate solution with a fresh organic extractant, within a pH range falling between 5.5 and 6.5 in a manner of counter-current extraction reaction therebetween to thereby make the remaining part of nickel still existing in the crude nickel sulfate solution extracted out into the organic extractant. In the method, the nickel-containing organic phase as separated in the second extraction step is divided into two portions, and one of these portions is used as the organic extractant to be fed into the second-stage extractor while the other is transferred to a by-pass, organic phase-scrubbing step of scrubbing it to remove sodium and ammonium from the thus-transferred, nickel-containing organic phase.
