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: The optical receptacle of the present invention comprises an optical receptacle body and a support member. The optical receptacle body comprises: a first optical surface upon which is incident light transmitted from the photoelectric conversion element; a second optical surface that emits light transmitted from the photoelectric conversion element to the light transmission medium. The support member comprises a support member body that includes a mounting surface for mounting on a substrate, and a second mating part that mates with the first mating part and that is positioned at a position on the inside of the support member body at a position corresponding to the first mating part. The optical receptacle is positioned on the support member side of the mounting surface.

Abstract: The problem addressed by the present invention is to provide: an optical receptacle that can be easily positioned with a photoelectric converter having a light-emitting element and a detection element. In order to solve the problem, an optical receptacle is provided, said optical receptacle being positioned between a light transmission medium and a photoelectric converter having a substrate, a photoelectric conversion element and a detection element, and the purpose of the optical receptacle being to optically couple the photoelectric conversion element and the end surface of the light transmission medium. The optical receptacle comprises a filter, a holding member for holding the filter, and a receptacle body. In the optical receptacle the holding member and the receptacle body are separate bodies, and the filter reflects towards the detection element side, as monitor light, part of the light emitted from the photoelectric conversion element, and transmits the remainder as signal light.

Abstract: The present invention addresses the problem of providing: an emitter that can be placed within a tube without aligning discharge parts of the emitter, is reduced in thickness while having a function for adjusting the flow rate, and is less likely to inhibit irrigation fluid flow. An emitter for solving the above problem is joined to the inner wall surface of a tube through which an irrigation fluid flows, and is used to discharge the irrigation fluid within the tube from a discharge port to the outside of the tube. The emitter has: at least one intake part; one discharge amount adjustment part; one discharge groove; and a plurality of discharge parts. The plurality of discharge parts are disposed symmetrically on both sides of the center of the emitter in a plan view.

Abstract: An emitter comprises: an emitter main body; and a discharge amount adjustment unit that adjusts the amount of irrigation liquid discharged from the discharge opening of a tube. The discharge amount adjustment unit has a diaphragm part formed integrally with the emitter main body in a position facing the inner wall surface of the tube when the emitter is joined to the inner wall surface, the diaphragm part deforming in accordance with the pressure of the irrigation fluid inside the tube. The diaphragm part has a discharge amount securing part on the surface of the side facing the inner wall surface, the discharge amount securing part securing the discharge of irrigation fluid from the discharge opening at or above a fixed amount, even if the diaphragm part deforms and adheres to the inner wall surface.

Abstract: This emitter has an emitter body and a pedestal. The emitter body includes: a water intake part for introducing irrigation liquid; a pressure reducing flow passage groove which is for forming a pressure reducing flow passage which communicates with the water intake part and allows the irrigation liquid to flow out while reducing the pressure of the irrigation liquid; an accommodation part which communicates with the pressure reducing flow passage groove and into which the irrigation liquid flows while the pedestal is accommodated therein; and a flexible diaphragm part which approaches the pedestal upon receiving the pressure of the irrigation liquid inside a tube while the pedestal is accommodated in the accommodation part. The pedestal has through-holes for discharging the irrigation liquid that flowed into the accommodation part. The emitter body and the pedestal are connected through a hinge part.
