A solid-state light source includes laser diodes that emit a laser beam with a first wavelength, a rotatable support that is arranged in a beam path of the laser beam and a reflector that is arranged between the laser diodes and the rotatable support. A multiplexer generates a sequence of transport packets and associated program element information tables. The fasteners are integral with the body and are movable from a non-deployed position to a deployed position. The dielectric coatings so prepared have few if any defects, and depending on the amount and molecular weight of porogen used, can be prepared so as to have an exceptionally low dielectric constant on the order of 2. The polarizing film for an organic EL display device may be prepared by subjecting a laminate comprising a non-crystallizable ester type thermoplastic resin substrate and the polyvinyl alcohol type resin layer formed on the substrate, to 2-stage stretching consisting of preliminary in-air stretching and in-boric-acid-solution stretching.
