A retractable cover for protecting small vehicles from the weather elements which substantially covers the top and side surfaces of the vehicle. Accordingly, there are provided a non-volatile semiconductor memory device which suffers almost no deterioration in the properties and can perform the operation of recording of 2 bits per unit memory device even when the size of the semiconductor memory device in the semiconductor substrate is scaled down, and a process for fabricating the non-volatile semiconductor memory device. The aperture extends from an inner surface to an outer surface of the base. The contacts are arranged such that, when the first and second connector assemblies are electrically connected to each other, the far end crosstalk on the victim pair in the first connector assembly has a magnitude and a polarity, and the far end crosstalk on the victim pair in the second connector assembly has the same magnitude and an opposite polarity. The rotor body frictionally engages the stator body to produce a predetermined coulomb torque frictional resistance.
