    Abstract: This emitter comprises an emitter body and a resin film, and has a water intake part, a discharge part, a flow channel, and a flow rate reduction part. The water intake part takes in irrigation liquid. The discharge part discharges the irrigation liquid. The flow channel connects between the water intake part and the discharge part so as to allow the irrigation liquid to circulate therein. The flow rate reduction part reduces the flow rate of the irrigation liquid in response to a deformation of the film caused by the pressure of the irrigation liquid. At least one of the surfaces of the film includes a spiral-shaped ridge part disposed at a position corresponding to the flow rate reduction part.

    Abstract: This emitter has an emitter body, a film, and a cover. A sealed space is formed between the cover and a portion of the film. A flow channel in the emitter include: a first through-hole that is opened in a first surface and a second surface of the emitter body; and a second through-hole that is disposed downstream of the first through-hole. The film is disposed so as to block first surface-side openings of the first through-hole and the second through-hole. The film becomes distorted toward the side of the sealed space due to deformation caused in the film when the temperature of the film exceeds a preset value and when the pressure of irrigation liquid circulating within the flow channel exceeds a preset value, thereby creating a gap between the emitter body and the film, through which the first through-hole and the second through-hole are enabled to be connected.

    Abstract: An emitter having a water intake part, a discharge part, a channel, and a pressure reduction channel The pressure reduction channel includes a groove and a plurality of projections. The plurality of projections include first and second projections that are adjacent to one another in the groove depth direction. The first projections are positioned on one side in the depth direction of the groove, and when seen from a planar view, the tip ends thereof project from the inside surface of the groove so as to cross the center line of the groove. The second projections are positioned on the other side in the depth direction of the groove, and when seen from a planar view, the tip ends thereof project from the inside surface of the groove so as not to cross the center line of the groove.

    Abstract: A cartridge for detecting one or more characteristics of a fluid in a diagnostic assay system includes a plurality of chambers. At least one of the plurality of chambers includes a wall. The wall includes an intermediate portion disposed between an exterior surface and an interior surface of the wall. The intermediate portion can include a hygroscopic element configured to extend an active period of detection of a reagent. The intermediate portion can include a dummy material configured to slow a wetting of a reagent by the fluid. The intermediate portion can include an air gap configured to reduce internal stress and/or strain in the cartridge. A reagent can be enclosed by the wall of the at least one of the plurality of chambers. The reagent can be a lyophilized reagent.

    Abstract: This emitter (120) has double ridges provided around a hole (173) which forms a portion of a flow path between a reduced-pressure flow path and a discharge part. A first ridge (174), which is the outermost ridge, is provided with four first grooves (177) which intersect said ridge. A second ridge (175) is provided with one second groove (178) which intersects said ridge. As the external liquid pressure increases, a film (140) sequentially adheres to the first ridge (174) and the second ridge (175). The flow rate of an irrigation liquid is adjusted to an amount capable of passing through the groove or grooves in the ridge to which the film (140) is adhered.

    Abstract: This emitter has an emitter body having at least a concavity and a through-hole, and also has a flexible film that is joined to one or more surfaces of the emitter body, and blocks at least part of the opening of the through-hole and the concavity. The emitter also has a flow reduction part for reducing the flow of an irrigation liquid according to the pressure of the irrigation liquid inside the tube. The flow reduction part includes the concavity, a diaphragm which constitutes part of the film, and a valve seat to which it is possible to tightly adhere the diaphragm. The diaphragm includes a ring-shaped thin section positioned so as to surround the diaphragm region to be tightly adhered to the valve seat. The thin section is formed so as to both recess from the tube interior and also project toward the concavity.

    Abstract: This emitter (120) has a first valve seat part (174) provided around a hole (173) which forms a portion of a flow path between a reduced-pressure flow path and a discharge part. The first valve seat part (174) is formed by a three-step recessed circumferential surface, and is provided with one groove (175) which intersects said three-step recessed circumferential surface, and becomes shallower as said groove approaches the hole (173). As the external liquid pressure increases, a film (140) gradually bends towards the first valve seat part (174), and the open area of the groove (175) gradually decreases. The flow rate of an irrigation liquid is adjusted to an amount capable of passing through the opening of the groove (175).
