Abstract: An emitter (120) adjusts the flow rate of a liquid for irrigation to be discharged from a discharge opening (112) of a tube (110) so that, according to pressure of the liquid for irrigation within the tube (110) received by a second membrane (153), the flow rate is made smaller as the pressure becomes greater in a prescribed range of pressure. The emitter (120) is constituted by mating a first member (130) having a bottom surface with a shape that follows along the inside wall surface of the tube (110) and a second member (150) that includes the second membrane (153) and is mated to the first member (130).

Abstract: An electrostatic sprayer system for dispensing and dispersing a liquid containing a spray compound includes a spray cloud dispersal feature that reduces the time that a residual spray cloud containing droplets including the spray compound remains suspended after spraying. A method of dispersing the residual spray cloud is implemented by a control system that causes a flow control system to deliver a non-active gas or liquid in conjunction with stopping delivery of the liquid containing the spray agent and charged with the same polarity, so that a charged cloud of the non-active gas or liquid, which may be air, displaces the suspended active fluid particles. The non-active gas or liquid may be dispensed for a predetermined time interval as determined by the control system, or the operator may control the time interval during which that the non-active fluid is dispensed.
