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.

A speed-change transmission apparatus for effecting a speed-changing on an engine drive force with utilizing a continuously variable speed-change device, a plurality of planetary transmission mechanisms and a plurality of clutches is constructed to be capable of effecting the speed-changing operation smoothly, regardless of a centrifugal force generated in the clutches. An output from the continuously variable speed-change device and a drive force from the engine are combined by a planetary transmission section. The drive force from this planetary transmission section is transmitted via a clutch section to an output shaft. First, second, third and fourth clutches of the clutch section are configured to be switched over respectively between an engaged condition and a disengaged condition, as clutch members are engaged with or disengaged from output side rotational members.

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 causing undercut. To prevent this, 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 sort-circuiting arc welding, the short-circuit and arc are instantly controlled in accordance with the detected arc length or wire-supplying speed. This ensures the separation of the molten droplet and its transfer onto the base metal in regular manner. As a result, the growth and separation of molten droplet is not affected by magnetic blow of arc but is controllable.

In a discrete-time alternating-current motor control apparatus having a state estimation observer estimating a rotor angle and a rotor angular velocity based on a direct quadrature transformation model of the motor, the gain of the observer is changed over depending on an estimated angular velocity. As a result, the apparatus is applicable in a wide range of the motor speed.Furthermore, the phase difference between the winding voltages and the winding currents supplied to the state estimation observer is compensated depending on the estimated angular velocity, thereby improving the control accuracy.

A hollow cylindrical member includes a compression chamber and a reservoir partitioned by a circumferential step disposed on its inner wall surface and filled with an arc-extinguishing fluid. A piston loaded with a spring forms stationary contact and is slidably fitted into the compression chamber while the reservoir is connected to the exterior of the cylindrical member through a flared hole in an electrically insulating nozzle. A movable contact loosely extends through the nozzle to engage separably the piston. The stationary contact may be disposed in the reservoir while the piston serves as an arc contact. The spring may be replaced by a tulip-shaped member on the piston forced into a recess on the free end of the movable contact and leaving it upon the piston engaging the step.
