Patent number: 8259987Abstract: A slender-type diaphragm longer in a longitudinal direction and shorter in a transversal direction in relation to the longitudinal direction, has a base member and a slant member. The base member has a pair of extending members provided in parallel in the longitudinal direction as facing each other, and a curved section that protrudes toward a first side of the diaphragm in a vibration direction of the diaphragm from a first plane that includes the extending members, the vibration direction being perpendicular to the longitudinal and transversal directions. The slant member has a slant surface in relation to the first plane and connected to the base member in a manner that the slant member surrounds the base member in a second plane parallel to the first plane, the slant member having a curved surface in a cross section thereof in relation to a cross section of the base member in the transversal direction.Type: GrantFiled: January 9, 2008Date of Patent: September 4, 2012Assignee: Victor Company of Japan, Ltd.Inventor: Manabu Omoda

Patent number: 7743879Abstract: A diaphragm in one mode of the present invention comprises an outer shape section having a circle with one diameter, or a shape of a polygon to be inscribed in a circle with the one diameter; an inner shape section protruding in one direction with regard to a plane including the outer shape section, wherein a shape formed by projecting the inner shape section on the plane is rotationally symmetric about the central axis of the circle; and a vibrating face section linking the outer shape section and the inner shape section and having an inclined face inclined to the central axis, wherein any one of cross-sectional shapes of the vibrating face section is rotationally symmetric about an eccentric axis which is eccentric with regard to the central axis, the cross-sectional shapes being defined by a plane intersecting perpendicularly to the central axis. An electroacoustic transducer uses the above diaphragm.Type: GrantFiled: September 12, 2008Date of Patent: June 29, 2010Assignee: Victor Company of Japan, LimitedInventors: Kazuyuki Inagaki, Jiro Nakaso, Manabu Omoda

Patent number: 6916097Abstract: A light emitted from a semiconductor light emitting device array having a plurality of semiconductor light emitting devices arranged two-dimensionally on a substrate is converged by a condensing lens. In a light guide, a mirror surface is formed from a light incidence port to a light emission port along an inner wall surface. The semiconductor light emitting device array and the condensing lens are arranged in that order toward the light emission port inside the light incidence port of the light guide. A part of the inner wall surface of the light guide is narrowed down substantially along a condensing angle of the condensing lens. The light guide includes parallel inner wall surfaces facing each other, following a portion obtained by narrowing down a part of the inner wall surface, in order to emit the light (each color light) converged by the condensing lens while repeatedly reflecting the light on the mirror surface.Type: GrantFiled: April 12, 2004Date of Patent: July 12, 2005Assignee: Victor Company of Japan, LimitedInventors: Manabu Omoda, Ritsu Miyamoto
