摘要： An impeller includes a hub plate and a plurality of blades circumferentially disposed at intervals on one surface side of the hub plate. Each blade has a shape formed by piling up a plurality of blade sections in a blade height-wise direction of each blade in a reference impeller in which the hub plate intersects with the blades and which includes a linear element blade in the blade height-wise direction so as to form a curvilinear element blade. In piling up the blade sections, amounts of tangential lean and sweep to be applied to the blade sections are increased as it goes from an end face of at least one of a hub plate side end and a counter hub plate side end toward a span intermediate part of the blade.

摘要： A plurality of vaned diffusers is disposed on a concentric plate at intervals in a circumferential direction thereof, and each of the diffusers is a curvilinear element three-dimensional diffuser having blades which are extended from a hub side of a impeller to a shroud side thereof. The blades are formed in a form in which a blade serving as a reference is stacked in a direction of the height of the blade, which is a direction of a gap between the hub and the shroud. A dihedral distribution in which moving in a direction perpendicular to a chord direction linking a leading edge of the blade as the reference with a tailing edge thereof, is set as a positive movement is non-uniform from an end portion on the hub side to an intermediate portion of the height of the blade.

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.
