The invention proposes am improved twin MONOS memory device and its fabrication. Providing QoS treatment, of a bearer flow within a communication session established between two end devices using a different in-band signalling protocol is supported. If the customer seeking registration of a domain name requests, the registrar obtains contact information needed for registration from a proxy entity established for this purpose. The rotation driving device is comprised of a pull rope rotary disc, a unidirectional clutch device connected to the pull rope rotary disc, and a rewinding spring mounted between the pull rope rotary disc and a pull rope rotary disc box. A torsional vibration damper arrangement is assigned to at least one of the clutch areas, and whererelative to an axis of rotation the torsional vibration damper arrangement is arranged at least partially in the axial area of the first clutch area andor of the second clutch area.
