A coating method of supplying a treatment solution to a substrate and coating the substrate with the treatment solution by a spin coating method, includes mixing a solvent for the treatment solution lower in surface tension than the treatment solution into the treatment solution concurrently with a start of supply of the treatment solution or later than the start of the supply of the treatment solution, and then supplying the treatment solution to the substrate.

A rotary sprinkler comprises a rotatable irrigation head with one or more nozzles, associated with liquid feed lines, which extend thereto from a sprinkler base housing, and further comprises a static biasing control base located below the irrigation head, e.g. between the sprinkler base housing and the irrigation head. The sprinkler can comprise a flow regulator arm, whose movement, at least indirectly, results in reducing the cross-sectional area of liquid flow towards at least one of the nozzles, and a flow deflector arm configured to interfere with a liquid jet discharged from at least one of the nozzles in order to affect the angle and range of the liquid jet. The static biasing control base can comprise an array of biasing elements, which can bias a cam follower configured to rotate together with the irrigation head and transfer its rotational displacement to the flow regulator arm and flow deflector arm, e.g. through respective gear elements. The gear elements can be adjusted to control a ratio between the extent of deflection of the two arms due to the rotation of the cam follower. The rotatable irrigation head can comprise a cover for preventing exposure of the dynamic control elements to the exterior of the sprinkler.

The present invention is a water fountain control system that utilizes cameras to analyze movements of a human subject, and actuates one or more water fountain controllers in response to the movements to create a display incorporating spray patterns of the flowing water. The camera system records video in real time and generates optical signals that are sent to a processor running software that assesses the dimension, position, stance, and/or motion of the human subject and converts the data into recognized classes of movements and/or poses. Once the processor identifies the type of movements and/or poses, it sends signals to the actuators of the water fountains to control the fountains in a manner that implements stored predetermined visual effects generated by the fountain to create a visual presentation to an audience.

The present invention relates to a system (1) for applying at least two kinds of liquid onto respective targeted areas of a substrate (S). The system (1) includes first and second storage unit (10a, 10b) that accommodate first and second liquids (F.sub.1, F.sub.2); a pressured gas supply unit (20) that is fluidly connected to the first and second storage unit (10a, 10b); first and second applicator (30a, 30b) that are fluidly connected to the first and second storage unit (10a, 10b); and a controller (40) that is operatively connected to the applicator (30a, 30b). The pressured gas supply unit (20) causes pressure of a pressured gas to act on the liquids (F.sub.1, F.sub.2) within the storage unit (10a, 10b). The first and second applicator (30a, 30b) each include at least one nozzle (300a, 300b) disposed so as to face the substrate (S). The first and second applicator (30a, 30b) spray the first and second liquids (F.sub.1, F.sub.2) within the first and second storage unit (10a, 10b) from the nozzles (300a, 300b) toward the substrate (S) by the action of the pressured gas from the pressured gas supply unit (20). The controller (40) individually controls the first and second applicator (30a, 30b) so that the first applicator (30a) sprays the first liquid (F.sub.1) toward a targeted area for the first liquid (F.sub.1) on the substrate (S) and the second applicator (30b) sprays the second liquid (F.sub.2) toward a targeted area for the second liquid (F.sub.2) on the substrate (S). The present invention also relates to a method for applying at least two kinds of liquid onto respective targeted areas of a substrate (S).
