    摘要： A pulse arc welding machine in which the welding operations and welding current are controlled such that the molten portion of a wire electrode is not significantly splattered and the welding arc length and welding bead are uniform. The welding machine of the invention includes a wire electrode, a welding torch confronting a base material while being spaced therefrom, a shielding gas supplying unit for supplying a shielding gas to the welding area on the base material, and a wire feeding unit for feeding the wire electrode to the welding torch. A base current source supplies a base current between the wire electrode and base material with a pulse current from a pulse current source being imposed thereon. A pulse frequency varying circuit varies a number of pulses per unit time for the pulse current so that the number of pulses is proportional to the speed at which the wire electrode is fed thereby to set the average arc current.

    摘要： An electrical welding device which requires no high frequency insulation and an electrical discharge gap for maintaining the arc discharge is made large. A main power source supplies an arc discharge current through an electrical conductor to the welding electrode. A high frequency electric power source applies a high-frequency high voltage between the electrode and the material to be welded to generate a high frequency discharge for arc ignition in the electric discharge gap. A high frequency magnetic choke element, which is preferably a plurality of stacked annular ferrite discs, surrounds a predetermined part of the electrical conductor. A high-frequency bypass capacitor is utilized to ground the electrical conductor between the magnetic choke element and the main power source.

    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： A recording and reproducing apparatus includes an RLL encoder that encodes an information bit string to a code bit string and a RLL decoder that decodes the code bit string to the information bit string. The RLL encoder encodes the information bit string to the code bit string of a run-length-limited code at a high encoding rate satisfying a plurality of conditions of constraint regarding a string of successive zeros. The RLL decoder decodes the code bit string encoded by the RLL encoder to the information bit string.

    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.
