Abstract: A method of enhancing surface electrical conductivity of an article formed of a conductive polymer material, such as a conductive polymer film, includes the step of providing an article formed of a conductive polymer. The conductive polymer is made up of a dielectric polymeric material and conductive fibers. A desired pressure is applied to at least a portion of the article while simultaneously heating at least a portion of the article to a desired temperature. The desired pressure and the desired temperature are maintained on at least a portion of the article for a desired time period. This method reduces a polymer-rich skin layer on the surface of the conductive polymer material and helps to randomize the orientation of the conductive fibers on the surface.

Abstract: A low pressure regulator for a high pressure fuel pump includes a standard damping orifice, providing a constant level of piston movement damping by enabling a fluid pathway between a spring chamber and a return line. The low pressure regulator also includes a further damping orifice, which is covered by the piston when discharge port holes are open, the further damping orifice providing a further, variable level of piston movement damping by providing a further fluid pathway between the spring chamber and return line. The further damping orifice is open in a hydraulic accumulator mode and closed in a regulator mode, thereby reducing pressure spikes caused by insufficient spring chamber filling.

Abstract: An apparatus for orienting a partially coated spherical-object includes a pedestal, a camera, and a controller. The spherical object contains a coating over a portion of a surface. The coating defines a spherical-cap, and the spherical cap defines a polar-axis.
