The foaming nozzle also includes a first row of first through holes fluidly coupled to, and extending between, a first row of first through hole inlets at the inner surface of the wall and a first row of first through hole outlets at the outer surface of the wall. The foaming nozzle also includes a second row of second through holes disposed axially adjacent to the first row of second through holes with respect to a longitudinal axis of the inner plenum, where the second row of second through holes is fluidly coupled to, and extending between, a second row of second through hole inlets at the inner surface of the wall and a second row of second through hole outlets at the outer surface of the wall. The foaming nozzle also includes cross-sections of the first through holes and the second through holes having regular shapes.

The dilute chemical solution supply device (1) comprises: a dilute chemical solution preparation unit (2) that prepares a dilute chemical solution (W1); a reservoir (3) for the prepared dilute chemical solution; a dilute chemical solution adjustment/supply mechanism (4) that supplies, as washing water (W2), the dilute chemical solution (W1) stored in the reservoir (3) to a plurality of single-wafer type washers (5A, 5B, and 5C); and a return mechanism that is connected to each of the single-wafer type washers (5A, 5B, and 5C) and refluxes excess water from the single-wafer type washers to the reservoir (3). According to such a dilute chemical solution supply device, it is possible to accurately adjust the concentration of the solute of the dilute chemical solution and suppress the discharge of excess water, and the dilute chemical solution supply device is thus suitable for washing of wafers, etc.

The present application discloses a device for diffusion of texture cleaning liquid, including a tank, a first turbulent plate and a second turbulent plate. The tank is provided with a liquid inlet; the first turbulent plate is fixed to and connected with the tank and is provided with a plurality of first orifices in interval; the second turbulent plate is fixed to and connected with the tank and is provided with a plurality of second orifices, and projection of each of the first orifices and projection of each of the second orifices on a plane where the liquid inlet is located are distributed in an alternate manner. The liquid inlet, the first turbulent plate, and the second turbulent plate are arranged sequentially in a liquid spraying direction.

A system and method of injecting a gas enriched and/or emulsified first liquid into a second liquid is disclosed. The injection can cause generation of a high density of bubbles having a mean diameter of a selected size. The mean diameter of the bubbles can be selected and varied based on the characteristics of the injection system.

Embodiments of the present invention address deficiencies of the art in respect to foam generation and provide a novel and non-obvious insert for a foam generation apparatus. In an embodiment of the invention, an insert for a foam generator includes a cylindrical cage and a multiplicity of fins extending from an interior portion of the cage towards a longitudinal axis of the cage, and at an inclined angle relative to the axis. The insert further includes at least one pad contacting the interior portion of the cage in a volume defined by opposing sets of the fins and the interior portion of the cage.

A bubble generator includes an ejector including a flow passage, a water supplier that supplies water into the flow passage, an air supplier that supplies air into the flow passage, a cleaner supplier that supplies a cleaner into the flow passage, and a bubble discharger that discharges bubbles generated by mixing the water, the air, and the cleaner; a water supply device that supplies water to the flow passage via the water supplier, and a cleaner supply device that supplies the cleaner to the flow passage via the cleaner supplier. The cleaner supplier is formed on a lower surface of the flow passage.

An apparatus for preparing a liquid preparation uses a two-part system. A first part includes a first reagent and a second part includes a second reagent. The first reagent and the second reagent react when mixed to form an active ingredient of the liquid preparation. The liquid preparation is a diluent. The apparatus includes a primary chamber for receiving a quantity of the first part, a quantity of the second part and a quantity of the diluent, a reagent inlet for admitting the first part and the second part to the primary chamber, a diluent inlet connectable to a diluent supply for admitting the diluent to the primary chamber, an outlet for releasing the liquid preparation from the primary chamber, and a flow controller to admit a pre-determined volume of diluent to the primary chamber in a pre-determined time period when the diluent inlet is connected to a diluent supply.

Disclosed is an apparatus and method for providing asymmetric oscillations to a container. The container may include a fluid, a particle, and/or a gas. A vibration driver attached to the container provides asymmetric oscillations. A controller connected to the vibration driver controls an amplitude, frequency, and shape of the asymmetric oscillations. An amplifier amplifies the asymmetric oscillations in response to the controller. A sensor disposed on the vibration driver provides feedback to the controller.
