A milling method and apparatus for the fabrication of components from materials that are difficult to cut for turbo-engines, producing recesses having one or more side walls, in particular for the fabrication of integrally bladed rotors for gas turbines, in which the recesses form flow channels and the side walls form blade surfaces of an integrally bladed rotor, are disclosed. During a calibration operation period, the calibration unit sets an operating characteristic of the AD conversion compensation unit and an operating characteristic of the DA conversion compensation unit. The system checks the extracted data and, if it is determined to be complete and correct, uses the extracted data to update the computer software in the television receiver. The exposed portion of the strained silicon layer is amorphized and re-crystallized to a crystal structure having an orientation the same as the semiconductor substrate. The storage circuit is used for representing data stored in the toggle magnetic tunneling junction element.
