A friction clutch wherein a pressure plate is axially movably but non-rotatably coupled to a cover and is biased by a diaphragm spring to urge the friction linings of a clutch disc against a flywheel which is driven by the engine of a motor vehicle. The first image processing option key is associated with a first image processing function and the second image processing option key is associated with a second image processing function that is different from the first image processing function. In addition, a supporting material is provided on a layer to be peeled of the second semiconductor substrate before the second semiconductor substrate is subjected to a second dividing treatment. A feed point is disposed on one end of the radiation path, corresponding to the ground point; and a first connecting point is formed on the radiation path. The device may further include an antenna connected to the transceiver, and at least one electrically floating, electrically conductive, antenna beam shaping element secured to the surface of the portable housing for directing a beam pattern of the antenna.
