摘要： A light incident into a wedge type light scattering conducting element from a light incident surface of the light scattering conducting element is converted into a light flux having a directionality and is output from a light output surface. The output light is input to a wedge type emitting direction characteristic adjusting element arranged with a positional relationship complementary to the light scattering conducting element. A prism shaped irregularity for adjusting a propagating directionality of the light in longitudinal/transverse directions is formed on a light input surface/light output surface of the wedge type emitting direction characteristic adjusting element. The wedge type emitting direction characteristic adjusting element has a weakened scattering power depending on requirements, thereby a degree of directionality sharpness of the light emitted from a surface light source device is adjusted. Various modifications are provided for the light scattering conducting elements, and regions having different scattering powers are combined for various patterns. The device is useful for A backlight source.

摘要： Light is supplied into a light incident surface 2 from a fluorescent lamp L enclosed by a silver foil sheet R, and parallelized illuminating light flux is taken out from a light exit surface 3. On a back surface 4 side of a light flux parallelizer 1, across or without a thin air layer 5, a polarization converter &Sgr; is disposed. The polarization converter &Sgr; reinforces the polarization function of the surface light source device through polarization conversion action accompanying reflection in the prism. At a position confronting the light exit surface 3 across an air layer 7, a polarization separating plate 8 is disposed. At a further outside, across an air layer 9, an exit light direction modifier 10 is disposed. A bright polarized illuminating light flux is emitted from a light exit surface 11. When applied to a backlight of a liquid crystal display, a liquid crystal display panel is disposed at a further outside of the exit light direction modifier 10.

摘要： A wedge shaped parallelized light flux element made of a light scattering guide of an emitting directionality has a specified ranged effective scattering irradiation parameter and correlation distance "a". A light incident into the parallelized light flux element from a fluorescent lamp arranged facing a light incident surface of the parallelized light flux element is emitted from a light output surface as a parallelized light flux G1 by composite factors including forward scattering of the inside, repeated reflection on wedge shaped two sides, critical angular condition and boundary face transmittance for the light output surface. A total amount of parallel light flux G1 emitted from the parallel light flux emitting section F is reflected on a two side prism surface of two prism reflection element PR thereby being converted into sectional area enlarged light fluxes G2 and G3. They are incident on a liquid crystal panel LP through a light diffusion plate DF, and utilized as a backlight. Reflective appearance of a light supply source for supplying a light to the light scattering guide is prevented by forming a reverse slope portion or the like on back surface of the light output surface in adjacent to the light incident surface of the parallelized light flux element.

摘要： A process for separating components of a gas mixture using gas-separation copolymer membranes. These membranes use a selective layer made from copolymers of partially fluorinated or perfluorinated dioxolane monomers and a second monomer, such as dioxane or a partially fluorinated dioxolane. The resulting membranes have superior selectivity performance for gas pairs of interest while maintaining fast gas permeance compared to membranes prepared using conventional perfluoropolymers, such as Teflon® AF, Hyflon® AD, and Cytop®.

摘要： A circuit board, onto which an electronic component is to be mounted, is provided with insulating core substrates and patterned metal plates. The metal plates are bonded to at least one side of the insulating core substrates. The insulating core substrates and the metal plates form a laminated body, in which a gas-vent hole is provided. The gas-vent hole is formed so that when the electronic component is mounted, the gas present between the insulating core substrates and the metal plates expands and is released to a side open to the atmosphere via the gas-vent hole.
