A cable retainer for a cable having a longitudinal axis and a given diameter has a first elongated body half arrayed along the longitudinal axis and having a first surface and a second, oppositely disposed surface, the second oppositely disposed surface having a first cable receiving section therein with a depth at least one half of the given diameter. The conveying sheet has a plurality of slits formed close to the end portion where it is fixed to the agitator and extending in the direction from the end portion to the tip end of the conveying sheet. A Ge concentration of the SiGe base layer is increased from 0% to 10% from a side of the emitter layer towards a side of the collector layer. Changes in the hue of a moving pointing device are translated into movement of the cursor on the display of an electronic device. The support housing includes an adjustment mechanism, and the elastomer assembly includes an outer ring that encircles an elastomeric material, a central bushing embedded in the elastomeric material, and a plurality of shims embedded in the elastomeric material in a parallel planar fashion. A method for forming a functional material layer includes the composition onto a substrate using ejection device.
