摘要:
A device for optical examination of human skin and its pigmentation comprises a cylindrical housing in which are arranged an optical observation device and a vertical illumination device. Where it faces the skin the housing is delimited by a plate made of transparent plastics or glass, which is applied to a skin site to be examined without introducing an immersion fluid. Light polarization devices are situated between the illumination device and the transparent plate and between the transparent plate and the optical observation device, their degree of polarization being controlled or, optionally, their location being movable mechanically into or out of particular light beam paths.
摘要:
A fuel cell is provided including a single sheet film or ribbon of any leh of a Polymer Electrolyte Membrane ("PEM") wherein the PEM is divided into regions or zones of varying electrical conductivity and ionic conductivity, allowing the elimination of endplates and/or a bipolar configuration. In this non bipolar arrangement, means are provided for distributing fuel to only one side of the PEM and oxidant to only the other side of the PEM so as to prevent mixing of the fuel and oxidant.
摘要:
A solid polymer electrolyte membrane is treated by brief exposure to a gaslasma prior to the inclusion of the membrane in a fuel cell as a separator between a liquid or gaseous fuel and an oxidant.
摘要:
Freestanding, flexible, heterogeneous composites of insulating polymeric m containing relatively small percentages of an electrically conductive polymer wherein the conductive polymer exists as the dispersed phase are made by dissolving the insulating polymeric material and less than 15 percent by weight of the electrically conductive material in a solvent, casting the resulting solution onto a suitable substrate and slowly evaporating the solution at an elevated temperature.
