    摘要: The present invention eliminates the need to stop the operation of a line even when trouble arises before, during, or after an operation of joining metal blocks in hot rolling. According to a specific solving means of the present invention, when a succeeding metal block is to be subjected to hot finish rolling in succession to a preceding metal block after the leading end of the succeeding metal block is joined to a tail end 10B of the preceding metal block on the inlet side of a finish rolling mill 26, it is determined before and after joining whether or not endless rolling is impossible. When it is impossible, joining is aborted, and the succeeding metal block 12 is temporarily stopped, is fed again after the tail end 10B of the preceding metal block moves out of the finish rolling mill 26, and is finish-rolled under the conditions set for batch rolling. When joining was not performed successfully, a joint 11 is cut between a joining unit and the finish rolling mill 26, and the rolled material is bitten by the finish rolling mill set for batch rolling.

    摘要: Assuming that the processes of joining, rolling, coiling, etc. of a material is evaluated by a preset speed pattern after the extraction from a heating furnace, the required time is predicted and calculated for both of a preceding material and a following material. At the time when the following material can catch up with the preceding material at an aiming position on the line, the following material is extracted from the heating furnace according to the result of the above prediction calculation. Control is carried out so that both of the preceding material and the following material finish the process at a preset speed. Also, the traveling speed of the following material is controlled according to the position and the speed of the tail edge of the preceding material in a section close to the catch-up position so that a distance between the tail edge of the preceding material and the leading edge of the following material be closed. Thereby, three of the tail edge of the preceding material, the leading edge of the following material, and a movable joining apparatus are controlled at the aiming position on the hot rolling line so as to be in a positional relationship suitable for joining, by which the joining operation is completed properly in the travel zone of the joining apparatus.

    摘要: A moving picture encoding apparatus divides a moving picture signal into key frames and non-key frames, encodes the key frames, predicts the non-key frames from the encoded key frames, determines a final encoding rate for each non-key frame, encodes each non-key frame, and outputs an error-correcting code at the final encoding rate as encoded data of the non-key frame. To determine the final encoding rate, the number of error-correcting bits needed to correct prediction errors is estimated by a first method and one or more second methods. The second methods are used to decide whether to use the number of bits estimated by the first method as the final encoding rate, or whether to supplement the estimated number of bits by adding an encoding rate correction. As a result, the encoding rate is not supplemented unnecessarily and the encoding efficiency is improved.

    摘要: A moving picture sequence is divided into key frames, which are coded by a conventional method, and non-key frames, which are coded to obtain error-correcting information. The encoder and decoder independently generate predicted images for each non-key frame. The encoder compares its predicted image with the original non-key frame to estimate how much error-correcting information the decoder will need to decode the non-key frame by correcting prediction errors in the decoder's predicted image, and sends the decoder that amount of error-correcting information together with correlation information indicating how closely the predicted image and the original non-key frame are correlated. Before decoding the non-key frame, the decoder modifies the correlation information to compensate for differences in the prediction methods employed by the encoder and decoder. The modification enables the decoding process to converge faster.
