A programming circuit and method to apply a controlled or predetermined voltage pulse for charge transfer to or from the floating gate of a non-volatile memory cell in an incremental manner to control the overall voltage across the gate oxide. The base material has dispersed therethrough, in a penetrating gradient, a desired amount of friction modifying particles. A wheel is coupled to the wheel axel. In other embodiments, the mounting member is integrally formed with the object or no mounting member is employed. In an exemplary embodiment, the method and circuit may be used to produce an output clock signal with a frequency that is two-and-a-half times lower than the frequency of the input clock signal. The front roof element is movably supported on the middle roof element, and the front roof element can be lowered or raised by a carrier mechanism which supports the front roof element on the middle roof element when the roof is being moved to over or under the middle part by a lengthwise guide.
