Abstract: A master cylinder device includes a reservoir tank, a master cylinder, a piston, and a pair of cup seals. The master cylinder includes a cylinder body having a cylinder chamber and a master port. The piston is inserted into the cylinder chamber, and has a relief port that communicates with the master port. The cup seals are provided on an inner circumference of the cylinder chamber, being positioned in front and rear of the master port, and seals a space between the inner circumference of the cylinder chamber and an outer circumference of the piston. The relief port is closed by the front cup seal, as the piston moves forward, to generate brake fluid pressure in a brake fluid in a hydraulic chamber. The relief port is tilted from a front side to a rear side, from the outer circumference toward an inner circumference of the piston.

Abstract: An OCT apparatus includes an OCT optical system guiding measurement light to a region including a central portion and a peripheral portion of a fundus, and an image processor processing a spectral interference signal output from the OCT optical system to acquire OCT data of an examinee's eye. The OCT optical system includes a first reference optical path having a path length for obtaining OCT data including the central portion and a second reference optical path having a path length for obtaining OCT data including the peripheral portion. The image processor obtains OCT data including the central portion based on an interference signal between measurement light guided to the central portion and reference light from the first reference optical path, and obtains OCT data including the peripheral portion based on an interference signal between measurement light guided to the peripheral portion and reference light from the second reference optical path.

Abstract: 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.

Abstract: A mobile terminal device having a ringing device includes a first control unit configured to be activated at a first activation time after power on; a second control unit configured to be activated at an activation time that is later than the first activation time; and a sound source configured to output a ringing sound in accordance with a program instruction, based on activation of the first control unit.

Abstract: It is an object of the present invention to provide a method for effectively regenerating bone, and more specifically to provide a method for regenerating bone that is capable of treating patients suffering from bone defect or bone injury. The present invention provides a method for regenerating bone, which comprises culturing and/or transplanting mesenchymal cells in the coexistence of epithelial cells.

Abstract: 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.

Abstract: A fiber of ethylene-vinyl alcohol copolymer having a specific degree of crosslinking which is obtained by acetal decomposition regeneration reaction with a specific crosslinking agent. Because of its effective degree of crosslinking, this fiber has a greatly improved resistance to steam ironing and finds use for garments and living material.
