The axle comprises:an axle housing including an intermediate casing containing a lubricant and in which a reduction gear unit, coupled to a differential, is mounted,two drive-shafts coupled to the differential, anda rotary electric drive motor having a shaft a first end of which extends into the casing where it is engaged in the tubular hub of an input sprocket of the reduction unit. The vehicle seat is fixed by connecting a striker disposed on the back face of the seat back with a dragger unit disposed on the vehicle body side. The second frequency being higher than a cutoff frequency of a harmonics generation spectrum characterizing the interaction of the substance with the first optical field. A multi-zone response model for each pair of actuator set and sheet property profile is created from the discretized response profile of the actuator zones in the actuator set. In this method, it is possible to manufacture a wafer with cracking resistance even if it is subjected to a millisecond annealing by the FLA annealing treatment.
