摘要： The spiral pipe joint comprises a nipple 1, a caulking ring 2 and a flexible string-shaped pressure contact member 3. After an inserting portion 11 of the nipple 1 is inserted into a pipe body P, the pressure contact member 3 is wound once or more times around the outer peripheral surface of the pipe body P existing above the inserting portion 11, and the caulking ring 2 is placed on the outside of the thus wound pressure contact member 3 and is compressed in the center direction of the pipe body P to thereby reduce the diameter of the caulking ring 2 in such a manner that the caulking amount thereof on the small-diameter stepped portion 13 is larger than the step level difference between the inserting portion 11 and small-diameter stepped portion 13.

摘要： This invention is an MPEG decoding apparatus (10) for decoding a compression-coded image data stream, the apparatus including a motion compensation circuit (15) and error map table holding means (19) for holding an error map table with respect to a decoded frame to be referred to in performing motion compensation. When the error map table is referred to and an error block is found to be included in a reference area, or when dynamic image data of a decoding target block is broken, the motion compensation circuit (15) performs error conceal processing to interpolate a pixel in the decoding target block with a pixel in the decoded frame and output the resulting data. The motion compensation circuit (15) generates an error map table showing the error-concealed block as an error block and stores this error map table. This MPEG decoding apparatus (10) restrains propagation of an error due to the error conceal processing and reduces deterioration in image quality.

摘要： A reference frame block from a memory is supplied to a feature extraction circuit and a search frame block from a separate memory is supplied to a feature extraction circuit. Within the extraction circuits, the frame blocks are divided into minor blocks and the integration of all pixels for each minor block gives a matching element. A matching process with the matching elements from the extraction circuits provides a frame motion vector. Data division circuits divide the matching elements provided from the extraction circuits into odd- and even-field matching elements, and the matching process with the odd- and even-field matching elements provides odd- and even-field motion vectors. This eliminates the need for a feature extraction circuit when obtaining field matching elements.

摘要： A reference block is divided in the horizontal direction into small blocks, and is also divided in the vertical direction into small blocks. Feature values representing each of the small blocks formed from the reference block are obtained. Similarly, a check block is divided in the horizontal and vertical directions into small blocks and feature values representing the small blocks formed from the check block are obtained. The feature values in the horizontal direction of the reference and check blocks are compared, and the feature values in the vertical direction of the reference and check blocks are compared. The results of the two comparisons comprise an evaluation value by which the degree of matching of the reference and check blocks is evaluated. The check block is moved throughout a predetermined search range, and the process is repeated for each position of the check block. A motion vector is produced between the reference block and the check block position at which the check block best matches the reference block.

摘要： Initially, forward prediction reference block data which has been read out from a reference frame memory and retrieval block data which has been read out from a retrieval frame memory are used to detect forward prediction motion vector and its residual by a forward prediction motion detecting circuit to preserve (store) them into a forward prediction motion vector/residual preservation memory. Then, backward prediction reference block data which has been read out from the reference frame memory and retrieval block data which has been read out from the retrieval frame memory are used to detect, by a backward prediction motion detecting circuit, backward prediction motion vector and its residual, and to read out motion vector and its residual which have been preserved (stored) in the forward prediction motion vector/residual preservation memory to carry out encoding by using these motion vectors in both directions.
