摘要： An error correction device error corrects without increasing in circuit scale. An encoder, includes: a first ECC encoder which interleaves a data string into n (n≧2) blocks of data strings at every m (m≧2) bits, and adds the error correction code parity; a parity encoder which creates a parity bit at every plurality of bits of the error correction code word, and adds the parity bit to said error correction code word; and a second ECC encoder, which generates a second error correction encoding, which is a linear encoding using iterative decoding. Concatenated type encoded data, where a parity bit is added to every plurality of bits, is created, so an increase of circuit scale can be prevented even if a data string is interleaved into a plurality of blocks and error correction code parity is generated.

摘要： When a zero run, which violating G constraint of a run-length-limited (RLL) code, is detected from the data stored in a first input register 1111 and a second input register 1112, bits before and after the zero run is transferred to a temporary register 1150 via a bus for zero run removal 1130 to be combined to each other. Thus, by effectively using the mechanism of bus transfer, a circuit can be simplified, thereby realizing a small circuit.

摘要： An encoded-bit-string generating unit generates a bit string encoded by scrambling an input bit string. A direct-current-component evaluating unit selects a bit string having a predetermined width in the bit string generated by the encoded-bit-string generating unit, while shifting bits one by one, and evaluates the direct-current component in the selected bit string. A bit-string extracting unit extracts a bit string with suppressed direct-current component, based on a result of an evaluation by the direct-current-component evaluating unit.

摘要： An indexing device comprises an indexing table fixed to a table shaft rotatably supported on a body structure. A worm shaft is rotatably supported on the body structure and has a worm formed thereon. An indexing gear is fixed coaxially to the indexing table. The indexing device has a rotation correction device for stopping the rotation of the worm shaft prior to the indexing operation of the indexing table. The indexing device further has a positioning device for operating, after the worm shaft has been thus stopped, to impart a rotational torque to the indexing table and to cause a gear tooth face of the indexing gear to press against and hold a worm tooth face of the worm, whereby the precision of positioning of the indexing table is improved.

摘要： A device for rotationally indexing an indexing table by utilizing a synchronized tap function of a machine tool main spindle. The rotation and the axial feeding displacement of the main spindle are in a specific synchronized relation. When the main spindle is fed forward, it engages an input shaft of the indexing device and thrusts it to retract against a spring force. Upon arriving at a retracted position of the input shaft, the main spindle starts rotation in one direction. Because of a one-way clutch between the input shaft and the indexing table, the rotation of the input shaft imparted by the main spindle is not transmitted to the indexing table. After a predetermined angular rotation and an axial feed, the main spindle is rotated in the reverse direction to be withdrawn axially. At this time the one-way clutch operates to transmit the reverse rotation to the indexing table. The indexing device is of compact construction and ensures accurate indexing.
摘要翻译：通过利用机床主轴的同步分接功能对分度台进行旋转分度的装置。主轴的旋转和轴向进给位移处于特定的同步关系。当主轴向前进给时，它与分度装置的输入轴接合并推动其抵抗弹簧力而缩回。当到达输入轴的缩回位置时，主轴在一个方向上开始旋转。由于输入轴和分度台之间的单向离合器，由主轴施加的输入轴的旋转不被传递到分度台。在预定的角度旋转和轴向进给之后，主轴沿相反的方向旋转以被轴向拉出。此时，单向离合器操作以将反向旋转传递到分度台。分度装置结构紧凑，确保精确的分度。
