Abstract: A surface light source device includes a substrate, a plurality of light emitting devices and a light diffusion plate. Each light emitting device includes a light emitting element and a light flux controlling member. A cross section, perpendicular to the central axis of the light flux controlling member, of the emission surface is line-symmetric with respect to the X-axis and the Y-axis, and the cross section has the shortest length along the X-axis and the longest length along the Y-axis. For the light flux controlling member of one of the light emitting devices that is disposed closest to a corner of the light diffusion plate in plan view, a part having a largest curvature in the emission surface on the cross section of the emission surface is located closer to the X-axis than an intersection point of a light beam with the emission surface is.

Abstract: The present invention relates to an emitter that can properly exhibit a flow rate adjustment function even when produced by molding a resin material having low hardness. The emitter has an emitter body and a base part stored in the emitter body. The emitter body comprises a water intake part, a reduced-pressure flow path groove, a storage part, and a diaphragm part. The base part has a base, a communication hole, and a deformation prevention part that is disposed protruding from the reverse surface to the surface of the base which the diaphragm part deformed by the pressure of a drip irrigation liquid contacts, and when the diaphragm part contacts the base by the pressure of the drip irrigation liquid, contacts the tube to prevent the base from being deformed by the pressure of the drip irrigation liquid.

Abstract: According to the present invention, a luminous flux control member of a light emitting device has an incident surface, a back surface, a reflection surface, an emission surface, and a first recessed portion. The first recessed portion includes a first inclined surface. With respect to a direction along the optical axis, a front end of the first inclined surface is positioned further toward the back side than light which is emitted from the center of a light emitting surface of a light emitting element, incident on the incident surface, reflected from the reflection surface, and transmitted toward the emission surface, and is positioned further toward the front side than light which is directly transmitted toward the emission surface without being emitted from an end on the light emitting surface of the light emitting element, incident on the incident surface, and passing by the reflection surface.

Abstract: Separate structural units for an inner gear and a housing of a planetary gear device include an inner gear with a first raised portion formed on the outer peripheral surface of the inner gear, where the first raised portion extends towards in a direction that is inclined with respect to the axial direction of the inner gear. A housing includes a second raised portion formed on an inner peripheral surface, where the second raised portion extends in a direction that is inclined in respect to the axial direction. The housing contains the inner gear such that there is a gap formed between the inner peripheral surface of the housing and the outer peripheral surface of the inner gear. Movement of the inner gear within the interior of the housing is limited through linear contact of the first raised portion and the second raised portion.

Abstract: An optical receptacle includes an optical receptacle main body and a filter. The optical receptacle main body includes a first optical surface, a second optical surface, a third optical surface, and a reflecting surface. The filter includes a first filter that reflects light of a first wavelength and allows light of a second wavelength to pass therethrough, and a second filter that reflects the light of the second wavelength and allows the light of the first wavelength to pass therethrough. The filter is disposed on the optical receptacle main body such that the first filter or the second filter makes intimate contact with the reflecting surface. A second central axis of the second optical surface do not coincide with a light axis of a light-receiving element. A third central axis of the third optical surface do not coincide with a light axis of a light-emitting element.

Abstract: An optical component is configured to optically connect a light-emitting element and an optical fiber, and includes an optical surface arranged in a middle of an optical path of a light to be emitted from the light-emitting element to the optical fiber to reflect the light. The optical surface includes an optical path area configured to reflect the light and a non-optical path area other than the optical path area, and the optical path area and the non-optical path area are coplanar. The optical path area has a smooth surface, and at least a part of the non-optical path area has a rough surface which is rougher than the optical path area.
