Abstract: A floating body for an offshore wind turbine includes: one first column; two second columns; two lower hulls connecting the first column to each of the second columns; and a beam member connecting the two lower hulls. The beam member is disposed within a height range between an upper surface and a lower surface of each lower hull.

Abstract: There is provided a video reproduction apparatus which reduces memory areas for storing video data of decoded bidirectional predictive frames, which apparatus can output the decoded video signals of the entire fields even when all the video signals are outputted by the reproduction in the temporally reverse-direction or the reproduction of searching for arbitrary pictures.

Abstract: A video reproduction apparatus comprises a decoding control unit 1207 for controlling a decoding process on the basis of header information, to which an instruction for repetitive display of image is inputted; a protection processing unit for calculating a position of a coded image data stream on a coded image data stream storage buffer 1202 on the basis of a position of the coded image data stream on a decoding target input buffer 1204, which position is supplied from the decoding control unit 1207, and protecting the coded image data stream so as not to be overwritten with another coded image data stream; and a coded image data stream transfer unit 1203 for performing retransfer of the coded image data stream on the basis of the position of the coded image stream on the decoding target input buffer 1204.

Abstract: The optical disk controller of this invention that reduces the frequency of output of status reports to relieve the burden of a system controller includes: a status generator for generating status reports each representing the operation state of the optical disk controller every sector of a disk; and a status sampling section for sampling the status reports at a set sampling interval. When a generated status report matches with “sampling abort” status stored in a sampling category storing portion, status sampling is aborted.

Abstract: In modifying a program fixedly recorded in a ROM or the like, desired positions in the program can be modified with a little hardware. In order to achieve the object, the program modification device comprises the modifying address register 17 which stores the addresses of program data to be modified prior to the execution of the data and the modifying address storage table 19 which stores all the addresses of the modification source programs to be loaded to the modifying address register 17 and all the addresses of the modification target programs in pairs, and further comprises a modification target program having instructions embedded therein so as to load necessary information from the modifying address storage table 19 to the modifying address register 17 before the program to be modified is executed.

Abstract: The demodulated signal from the optical disk, containing a plurality of addresses is supplied to the address decoder which sets error detection flags when address decoding fails. If all addresses fail to decode, an address interpolator performs address interpolation up to a stored maximum number of iterations, thereby allowing data to be continuously read out from the demodulated signal. The maximum number is stored in memory. If at least one address is decoded, the address interpolator selectively updates the stored maximum number to achieve higher performance in reproducing data items from the optical disk.
