Patent EP-0472852-A2 (EP)
Inventor: STURM HARALD DR
IPC: C08F265/04
Filed: 1991-06-28
Abstract: A process is described for the preparation of thermoplastic compositions based on vinyl chloride homopolymers or copolymers and polyacrylates and having a glass transition temperature of below -20 DEG C. First, the acrylate is polymerised in aqueous emulsion in the presence of crosslinking compounds which are copolymerisable with the acrylates and have at least two non-conjugated double bonds. In the second step of the process, the vinyl chloride or vinyl chloride with up to 20% by weight of copolymerisable monomers is heated to a temperature of >/= 30 DEG C in aqueous suspension with an initiator, a suspending agent system and optionally additives. Only then is the polyacrylate added and polymerised at temperatures of > 30 DEG C to the desired conversion. The polymers prepared in this way have an improved particle size distribution and good reproducibility of the bulk density, and in particular caking on the walls of the reactor during the polymerisation is drastically reduced.

Abstract: A system for steering mutually phase-locked time-of-day (TOD) clocks in unison to a higher-precision reference clock. Periodically the count stored by a TOD counter responsive to one of the TOD clocks is compared with a reference count to provide an error signal. A proportional correction signal derived from the error signal is applied together with an offset to each of the TOD clocks to adjust the clock frequencies and thereby steer the TOD count toward the reference count. The steering offset is dynamically adjusted in such a manner that, when the offset signal is applied alone as a correction signal, the frequencies of the TOD clocks track that of the reference clock.

Abstract: When a specific signal such as copy guard signal(CG) is added between horizontal(HS) synchronizing signals in a composite synchronizing signal(SYN), and the addition period of the specific signal(CG) is defined in a specific period on the basis of the vertical synchronizing signal(VH), the composite synchronizing signal(SYN) is masked to remove the specific signal(CG), thereby obtaining a masked composite synchronizing signal(SYNO). Afterwards, from the masked composite synchronizing signal(SYNO), the horizontal synchronizing signal(HS) and vertical synchronizing signal(VH) are obtained. In the case of composite synchronizing signal(SYN) containing noise, without masking, the horizontal synchronizing signal(HS) and vertical synchronizing signal(VH) are directly obtained from the composite synchronizing signal(SYN). Therefore, when the noise signal is not contained, the horizontal synchronizing signal(HS) and vertical synchronizing signal(VH) without disturbance of image may be obtained.

Abstract: In a constant-voltage generating circuit wherein a first series circuit of PMOS transistors (Q P 1,Q P 2), a second series circuit of a PMOS transistor (Q P 3) and an NMOS transistor (Q N 1) and a third series circuit of PMOS transistors (Q P 4,Q P 5) are connected between a power source line (V CC ) and a ground line (GND), a capacitive element (Q N C) is connected between a common junction node (N1) of the PMOS transistors (Q P 1,Q P 2) of the first series circuit and the ground line (GND). In addition to this capacitive element, another capacitive element (Q P C) may be connected between the node and the power source line. Since the node (N1) is connected to gates of one (Q P 1) of the PMOS transistors of the first series circuit and the PMOS transistor (Q P 3) of the second series circuit, the capacitance at this node with respect to the power source line is large. Thus, when the power supply voltage fluctuates abruptly, the voltage at the first node also changes and thus the output voltage (V REF ) also changes. This phenomenon can be suppressed by the action of the capacitive element connected between the common junction node of the first series circuit and the ground line.

Abstract: An improved method and associated mechanism for facilitating the transformation of digitized images intended for use in a multi-resolution, multi-application environment by performing complex transformations on low resolution image components and approximate transformations on the high level image components so as to reduce computational complexity. In a preferred embodiment of the invention, the transformation operator is executed upon a relatively low spatial resolution file, thereby resulting in a substantial reduction in processing overhead. Advantage is thus taken of the availability of the reduced size of the lower spatial resolution base file within the hierarchical database, so that a relatively complex conversion may be performed on a small number of pixels within the base file, prior to up-converting the image to a relatively high spatial resolution image, such as a 2048 X 3072 pixel image for driving a high resolution digital thermal color printer.

Abstract: A rotatable-cassette-type feeding device, for use in an image forming apparatus for forming images on sheets of paper, has a paper cassette (6) for housing sheets of paper. This paper cassette (6) can be rotated either to the longitudinal feeding station or to the lateral feeding station of the sheets of paper by a driving motor (7). The rotatable-cassette-type feeding device (3) is provided with drive control means (Fig.5) for controlling the driving motor (7) in its rotation speed in such a manner that, during a state in which no copying process is required, the paper cassette (6) is rotated at a speed that is lower than that marked during an copying operation. Thus, when the rotatable cassette (6) is driven during the stand-by state, the motor (7) is rotated at a low speed. Thus, it is possible to reduce noise that is generated from the driving system and the motor (7) of the rotatable cassette (6), thereby making the device quieter.

Abstract: Apparatus for compression encoding video signals, comprising block segmenting means (3A, 3B, 3C) for segmenting a vertical interval, such as a field or frame, of video picture elements into a plurality of blocks of picture elements. An orthogonal transformation, such as discrete cosine transformation, of respective blocks is obtained (6), resulting in a two-dimensional array of transform coefficients of different values, the array being partitioned into respective areas. Each area is quantized (8) with a respective quantizing value that differs for different areas. Preferably, a transform coefficient is quantized by dividing the value of the transform coefficients in an area by a divisor 2 n/2 , where n is an integer that differs in different areas. The areas of the two-dimensional array of transform coefficients are formed by partitioning the array in a direction substantially perpendicular to the oblique frequency axis of that array.

Abstract: In the encoding of a frame (P3) in a digitised motion picture sequence, the frame is divided into blocks (A) of pixels and a motion vector (VA) found to predicts the contents of each block A from a block (A') in a previous frame (IO). Rather than evaluate many thousands of candidate vectors to find the best motion vector (VA), relatively few candidate vectors are evaluated, based on starting vector which is the estimated motion vector for a neighbouring block (LB(A)) in the same frame. To allow parallel processing of several pixel blocks, all the blocks of one row in the current frame are assigned to one processor (DSP), and a starting vector is obtained from a block (LB(A)) previously processed by the same processor. Further starting vectors are obtained if desired from neighbouring blocks (UR(B),DR(B)) in neighbouring frames of the sequence. The candidate vectors based on a starting vector may be very few in number, or may fill an area a few percent of the full search area. The method may favour candidate vectors which are more economical to encode.

Abstract: Apparatus and methods for determining whether a word/sense pair is proper for a context. Wide contexts (100 words) are employed for both training and testing, and testing is done by adding the weights of vocabulary words from the context. The weights are determined by Bayesian techniques which interpolate between the probability of occurrence of a vocabulary word in a conditional sample of the training text and the probability of its occurrence in the entire training text. A further improvement in testing takes advantage of the fact that a word is generally used in only a single sense in a single discourse. Also disclosed are automated training techniques including training on bilingual bodies of text and training using categories from Roget's Thesaurus.
