  • Publication number: 20070120343
    Abstract: An illuminated footrest for a motorcycle includes a base having an apertured flange on one end for connection to a mounting bracket, the base also including a cavity, at least one side opening and an end opening. A side lens and an end lens cover the at least one side opening and the end opening, respectively. An illumination source is positioned in the cavity and illuminates the side lens and the end lens. In one aspect, the apertured flange is replaced with an adapter for mounting the footrest on different motorcycle footrest mounting brackets.

  • Patent number: 4454524
    Abstract: A memory FET device having a channel implantation which controls gate parasitic transistor action. The parasitic action produces unwanted conduction paths which are formed in the transition regions between the thin memory oxide and the thick field oxide and extend along the sides of the gate region between the source and the drain. By blanket implanting through the oxide, which is relatively thin in the memory oxide region and increases in thickness across the transition region, and by adjusting the implant threshold, a continuous implant layer is formed which lies (1) within the field oxide, (2) at the substrate surface beneath the transition region oxide, and (3) deep within the body of the substrate beneath the gate region.
