摘要： An edge light type backlight unit having an improved light-reception portion. The backlight unit includes one or more light sources that emit light, a light guide panel that guides the propagation of light incident on one side edge thereof, one or more light-reception portions having a first entrance face slanted opposite the side edge of the light guide panel on which the light is incident at a predetermined angle, and one or more reflecting elements that are disposed between each of the light-reception portions and each of the light sources and guides the light emitted by the light source so that it is incident on the first entrance face.

摘要： A polyimide for optical communications, which is expressed by the formula (1), a method of preparing the same, and a method of forming multiple polyimide films using the polyimide, wherein the formula (1) is given by X1, X2, X3, A1, A2, B1, B2, B3, D1, D2, E1, E2, Y1, Y2, Y3, Y4, Y5, Y6, Y7, and Y8, are independently selected from the group consisting of hydrogen atom, halogen atom, alkyl group, halogenated alkyl group, aryl group and halogenated aryl group; Z is a simple chemical bond or selected from the group consisting of —O—, —CO—, —SO3—, —S—, —(T)m—, —(OT)m— and —(OTO)m—, wherein T is alkylene or arylene group substituted by at least one of halogen atom and halogenated alkyl group and m is an integer from 1 to 10; and n is an integer from 1 to 39. Because the polyimide expressed by the formula (1) has a lower birefringence than a common polyimide used as a material for optical waveguiding, a problem associated with the dependency of optical characteristics on polarization can be solved. Also, the solubility of the polyimide in an organic solvent is lowered, so that the occurrence of cracks in a polyimide layer can be avoided in the case of forming multiple polyimide films.

摘要： A method of forming a hydrophobic coating layer on a surface of a nozzle plate for an ink-jet printhead includes preparing a nozzle plate having a nozzle, forming a metal layer on a surface of the nozzle plate, forming a material layer covering the metal layer, selectively etching the material layer to expose a portion of the metal layer formed on an outer surface of the nozzle plate, and forming the hydrophobic coating layer of a sulfur compound on the exposed portion of the metal layer by dipping the nozzle plate in a sulfur compound-containing solution.
