    摘要： A fundus photographing apparatus for photographing a fundus of an examinee's eye includes: a photographing part including a photographing optical system for photographing the fundus; a mechanism for moving the photographing part; a presenting part for presenting a fixation target to the eye; an alignment detecting optical system including a light receiving element to detect an alignment state of the photographing part; and a setting part for setting an alignment completion position in a back and forth direction of the photographing part relative to the eye based on the detected alignment state. The alignment completion position includes a first alignment completion position information to be set when an optical axis of the photographing part is in a predetermined range relative to a corneal vertex of the eye and a second alignment completion position information to be set when the optical axis is apart from the predetermined range.

    摘要： A high-strength and highly wet-heat-resistant polyvinyl-alcohol-based fiber--in which the crosslinking agent has hardly been oxidized by the heat at the drawing time upon preparation of the fiber, the crosslinking agent has not exhaled so much at the time of dry heat drawing, and the crosslinking agent has penetrated even inside of the fiber so that not only the surface but also the inside of the fiber has sufficiently been crosslinked--can be obtained by the steps of: preparing a polyvinyl-alcohl-based fiber by spinning the polyvinyl-alcohol-based solution, wet drawing the fiber, applying an acetalization compound of an aliphatic dialdehyde having at least 6 carbon atoms to the fiber, subjecting the fiber which contains above compound to dry heat drawing to a total draw ratio of at least 15, and then crosslinking the drawn filament with an acid under mild crosslinking treatment conditions.
