    摘要: A magnetic memory includes a plurality of magnetoresistive elements which include a fixed layer in which a magnetization direction is fixed, a free layer in which a magnetization direction changes, and a nonmagnetic layer formed between the fixed layer and the free layer, and a word line electrically connected to the magnetoresistive elements. Data erase is performed by setting the magnetization direction of the free layer in a first direction by a magnetic field induced by a current flowing through the word line, and data of the magnetoresistive elements are erased by one time data erase. Data write is performed by setting the magnetization direction of the free layer in a second direction by spin-transfer magnetization reversal by supplying a current in one direction to the magnetoresistive elements.

    摘要: A receiving apparatus receives a bitstream that is divided into units encoding a moving picture and includes a stream header indicating how the units are to be decoded. The receiving apparatus estimates the contents of the stream header from the contents of the units, so that decoding of the units can begin before the stream header is received. The receiving apparatus preferably checks for errors in the analysis and decoding of the units, and modifies the estimated stream-header information when an error is discovered. The same unit may be analyzed and decoded repeatedly to hasten the correct estimation of the stream-header information.

    摘要: In pulse welding apparatus of arc welding or short-circuit transfer type arc welding in which a pulse discharge created on the tip of a wire electrode is utilized to perform welding, when a molten droplet produced on the tip of wire electrode is late to separate from the wire due to variations of welding conditions and external disturbances. The wire-supplying speed at which the wire is supplied to the weld zone changes. This causes undercut, i.e., a defect in welding bead-shape that presents adverse effect to welding quality. To prevent this problem, pulse current supplied to the base metal is divided into a plurality of pulse groups and the average current reaches the maximum peak value at a predetermined time after beginning of outputting the pulses, and the group of pulse currents is of a hill-shape in its envelope in accordance with the separation phenomenon of molten droplet, and the group of pulse currents is arranged to have different pulse period, pulse width, and pulse interval. In the sort-circuiting arc welding, the short-circuit and arc are instantly controlled in accordance with the detected arc length or wire-supplying speed.

A pulse current waveform control circuit, which controls the pulse arc current so that a desired pulse arc current is supplied to the arc welding power supply for outputting the pulse arc current to the welding load unit, is constructed such that the optimum welding operation may be performed without having to adjust circuit components and modify circuit design.

A modification of the program can provide any desired pulse arc currents without changing circuits. The optimum welding current waveform parameters or a target arc length signal is learned in the first welding stage and stored into a memory. An arc length feedback control or a current waveform control is performed under the control of program on the basis of the optimum welding current waveform parameters or the target arc length signal so as to control the faulty separation of globules when magnetic blow occurs and so as to reduce the variation of arc length due to external disturbances occurring at the welding torch so that improved welding quality is ensured under various environment.

    摘要: A pulsed arc welding for carrying out arc welding or short-circuit transfer type arc welding by utilizing the pulsed discharge generated at the tip of a wire electrode. The propensity of wire electrode curvature causes irregular changes in the contact point of the wire electrode and variations in the arc length between the wire electrode tip and workpieces. Consequently, the invention detects arc voltage and current and checks the instantaneous variation in the arc length. The arc voltage value thus detected is converted to a reference arc voltage variable. Then the detected arc voltage value is compared with the reference value to compute a true arc length. A simulation arc length signal, which varies as welding proceeds, and a reference simulation welding current waveform are set, to compare the simulation arc length signal with the computed arc length signal. The reference simulation welding current waveform is corrected according to this difference signal to form and output a welding current waveform, which is controllable instantaneously to provide an ideal target arc length. Welding can be carried out with stability since the wire electrode is allowed to hold the simulation arc length during each welding process.
