Abstract: This emitter is constituted from an emitter body, a film, and a cover. The emitter has a water intake part, a discharge part, a first flow path, a second flow path, a flow reduction part, a flow path opening/closing part, a pressure-reducing flow path, and a bypass flow path. When the pressure of an irrigation liquid flowing through a tube is less than a first pressure, the irrigation liquid passes through the pressure-reducing flow path and the bypass flow path and is guided to the discharge part. When the pressure of the irrigation liquid flowing through the tube is equal to or greater than the first pressure, the second flow path is closed by the flow path opening/closing part, and the irrigation liquid taken in from the water intake part passes through the pressure-reducing flow path and is guided to the discharge part.

Abstract: A slide piece driving mechanism includes a side surface guiding portion, a shaft portion, and stopper releasing means. The side surface guiding portion is disposed at a movable side mold to guide a side surface of a slide piece to be slidably movable. The shaft portion of a stopper is disposed at the side surface guiding portion. When the slide piece reaches an upper end position, the shaft portion engages with a stopper hole of the slide piece to prevent the slide piece from falling from the upper end position due to own weight. The stopper releasing means releases the engagement of the shaft portion of the stopper with the stopper hole to allow the slide piece from falling from the upper end position due to its own weight.

Abstract: The purpose of the present invention is to provide an ultraviolet sterilization device that can increase the ultraviolet irradiance near the center of a treatment flow path even at a position far from a light emitting element. This ultraviolet sterilization device comprises: a flow path tube having a linear treatment flow path therein; a light emitting element for emitting ultraviolet rays; and a reflector having a reflection surface for reflecting ultraviolet rays emitted from the light emitting element and collecting and directing the ultraviolet rays to the flow path tube. The ultraviolet sterilization device irradiates a fluid flowing in the linear treatment flow path with ultraviolet rays and sterilizes the fluid.

Abstract: The present invention provides a lens (i.e., luminous flux control member) for an optical element of a backlight, capable of easily aligning the orientation in the plane direction. The luminous flux control member according to the present invention includes a lens main body and legs. The lens main body includes a light-entering area for light emitted from a light-emitting element to enter on the lower surface side and a light-emitting area for emitting the light entered from the light-entering area to the outside on the upper surface side. The legs are legs for mounting the luminous flux control member on a substrate on which the light-emitting element is mounted and are disposed on the lower surface of the lens main body so as to project downward. The luminous flux control member satisfies the following condition 1 or 2: (Condition 1) at least one of the legs is accommodated in one of two grooves having different widths, and all of the other legs are accommodated in the other groove only when the lens main body is oriented in one predetermined direction or an opposite direction thereto; and (Condition 2) the lens main body or all of the legs are accommodated in one groove only when the lens main body is oriented in one predetermined direction or an opposite direction thereto.

Abstract: A marker (10) includes a lenticular lens (11) formed from a translucent material to have a plurality of convex portions (13) positioned to line up in, for example, at least one direction. The optical axes (OA1) of the convex portions (13) all intersect with an optical reference point (OP) on the product optical axis (PA). The optical axes (OA1) of the convex portions (13) are all orthogonal with and pass through the center of the bottom surfaces of grooves (14). Colored portions (15) are accommodated in the grooves (14).

Abstract: This optical receptacle has a first optical surface on which light emitted from a light-emitting element is incident; a light splitting unit which splits the light incident on the first optical surface into monitor light that travels toward the detecting element and signal light that travels toward the cross-section of the optical transmission body; a second optical surface which emits the signal light split in the light splitting unit toward the cross-section of the optical transmission body; and a third optical surface which emits the monitor light split in the light splitting unit toward the detection element. The first optical surface causes the light incident thereon to converge so that the beam waist is positioned in the optical path between the first optical surface and the second optical surface.

Abstract: The present invention provides a marker unit that can be easily installed in the same target object under the same installation condition, for example. The marker unit of the present invention includes: an upper substrate; and a lower substrate, wherein the upper substrate is laminated on the lower substrate to form a laminate. The lower substrate has a lower substrate detection target portion exposed to an upper surface side of the laminate on an upper surface thereof, and the lower substrate has at least two positioning portions on a lower surface thereof. The detection target portion is detectable from an upper surface side of the laminate, and each positioning portion is visually recognizable from a side surface direction of the laminate and is visually unrecognizable from the upper surface direction of the laminate. When the laminate is installed in an installation target object, each positioning portion is disposed on the lower substrate at a position corresponding to an alignment mark with the marker unit in the installation target object by recognizing from the side surface direction of the laminate.

Abstract: The present invention aims to provide an emitter and a drip irrigation tube that can suppress the variations in the discharge amount of the liquid caused by the temperature of the liquid in the drip irrigation tube. The emitter (120) of the present invention is disposed on an inner wall of a tube (110) including a discharge port (112), for regulating discharge of irrigation liquid from an inside of the tube (110) to an outside of the tube (110) via the discharge port (112). The emitter (120) includes an intake portion; a regulating unit; a discharge portion; and a flow path. The regulating unit includes: a recess; and a film. The film is fixed in a state of covering an inner space of the recess, and a region of the film covering the inner space of the recess is a diaphragm portion. The flow path has a decompression region for decompressing the taken-in liquid, the decompression region has a serpentine shape, and in the decompression region, a fluctuation ratio of a cross-sectional area in a direction perpendicular to an axial direction is within a range of 1±0.1 with reference to a smallest cross-sectional area.

Abstract: The present invention provides a marker that can prevent reflection from the surface of the marker and can project an image with an excellent contrast. The marker (100) of the present invention includes a lens main body (110). The lens main body (110) has multiple lens portions (103) on one surface side and has multiple detectable portions (105) on the other surface side. The lens portions (103) are arranged successively in a planar two-dimensional direction. On the one surface, a pitch of the lens portions (103) in a one-dimensional direction is narrower than a pitch of the lens portions (103) in the other one-dimensional direction.
