A strip treatment line in which downstream of the processing roll stand for stainless steel strip, first and second tension rolls are provided to directly form a prestretching zone A for elastic or elastoplastic stretching of the strip following the dressing mill stand and for providing an afterstretching zone with elastoplastic or plastic stretching of the strip. The semiconductor laser module has a structure in which the semiconductor laser device is set to a cooling device constituted by electrically alternately arranging 40 pairs or more of the Peltier elements and holding them by top and bottom ceramic plates and sealed in the package. The layer thickness of the deposited metal layer is determined from the resistance measurement. , at bit-level switching rates, the BS-based frequency conversion can be selectively performed on particular bits in the input signal, e. Examples of the one or more other therapies can include pacing, defibrillationcardioversion, cardiac resynchronization therapy, or neurostimulation.
