摘要： An illumination device for use in a slit exposure system for illuminating a document located on a document table. The illumination device has a light source with an elongated shape and a reflector surrounding a portion of the periphery of the light source and designed to reflect a light emitted from the light source toward the document. The reflector has a plurality of cylindrical reflecting surfaces. Each of the surfaces is designed to reflect while collimating a light virtually emitted from a linear area to be illuminated on the document table toward the light source, assuming that a line from which the light is emitted is located on the linear area.

摘要： Each of collectors 22 of an electrode structure 20, which partially constitutes a polymer electrolyte fuel cell, is formed from a metal lath MR having a large number of through-holes. A stopping portion 22a in which the through-holes are reduced in diameter is formed at a peripheral end portion of the collector 22. The peripheral end portion of the collector 22 is folded; subsequently, the folded peripheral end portion is pressed, thereby forming the stopping portion 22a. A resin seal portion 23 for sealing introduced fuel gas and oxidizer gas is formed integrally with the stopping portions 22a by insert molding which is performed such that an injected molten resin encloses the stopping portions 22a. The resin seal portion 23 formed integrally with the stopping portions 22a can reliably prevent inflow of the molten resin toward central portions of the collectors 22.
