A pump is disclosed which includes a pump body, a silencer connected to the pump body, and a condensation preventing device surrounding the silencer. A liquid supplying apparatus is also disclosed which includes the pump for providing a power to supply the liquid to outside, and a storage tank for storing a liquid.

In a substrate processing apparatus, the inner peripheral edge of a second-cup canopy part radially opposes an outer peripheral surface of an opposing-member side wall part. This suppresses dispersion of processing liquids to above a cup part. A second-cup gap distance that is a radial distance between the outer peripheral surface of the opposing-member side wall part and the inner peripheral edge of the second-cup canopy part is greater than a holder gap distance that is a radial distance between the inner peripheral surface of the opposing-member side wall part and the outer peripheral surface of the substrate holder. This prevents or suppresses the possibility that, when a second processing liquid dispersed from a substrate is received by a second cup, the second processing liquid may be pushed downward by a downward airflow. Accordingly, a plurality of types of processing liquids will be separately received by a plurality of cups.

An electromagnetic propulsion system for electrically conductive articles, such as aluminum beverage cans. Currents in coils disposed along a passageway induce currents in aluminum cans in the passageway. The electromagnetic fields produced by the coil currents and the eddy currents in the cans interact to produce forces that propel the cans along the passageway. A coil drive supplies the coils with a low-frequency current to propel the cans and a high-frequency current to heat the cans. The coils are arranged as solenoids encircling the passageway or as planar arrays bracketing the passageway. Besides being used to propel aluminum cans, the coils can be used to spin cans. The electromagnetic propulsion systems are shown in can washers and dryers.

While the described wand can include any suitable component, in some cases, it includes a wand head having a vacuum port with a front face and a back face, a jet port that is coupled at the back face of the vacuum port, and a jet that is coupled to the jet port, the jet being configured to spray effluent through the vacuum port to a surface to be cleaned. In some cases, the front face includes a first jog that extends from a front side of the front face and across a width of the front face. In some cases, the second face includes a second jog that extends across a width of the back face of the vacuum port such that the second jog extends into the vacuum port and defines a second recess at a back side of the back face. Additional implementations are also described herein.

A cleaning basket (120) for cleaning a breathing apparatus (112) is proposed. The cleaning basket (120) comprises at least one basket rack (140). Furthermore, the cleaning basket (120) comprises at least one mask holder (122) for holding at least one protective breathing mask (114) in the cleaning basket (120). Furthermore, the cleaning basket (120) comprises at least one suction element (156) which has at least one suction opening (160) and is configured to extend into the protective breathing mask (114) held by the mask holder (122). The suction element (156) is configured to be charged with negative pressure and to suck cleaning fluid out of at least one interior space (148) of the protective breathing mask (114) into the suction opening (160). Furthermore, a cleaning system (110) with the cleaning basket (120) and a cleaning device (118), and a method for cleaning the breathing apparatus (112) are proposed.

A system for and method of removing residues, deposits, and debris from a substrate that has been marked by a chemical etching process is disclosed. The system includes one or more upper sprayers that deposit a cleaning solution to a top surface of the product as it passes beneath the one or more upper sprayers. The system further includes at least one upper brush that operates to scrub the top surface of the product after the cleaning solution has been applied thereto. The system optionally includes one or more lower sprayers and lower brushes to clean a bottom surface of the product as it is conveyed through the system. The system further includes an air knife system that assists with drying the product prior to exiting the system. The system further includes a controller that is operable to adjust various system parameters.

The present invention provides techniques to more accurately control the process performance of treatments in which microelectronic substrates are treated by pressurized fluids that are sprayed onto the substrates in a vacuum process chamber. control strategies are used that adjust mass flow rate responsive to pressure readings in order to hold the pressure of a pressurized feed constant. In these embodiments, the mass flow rate will tend to vary in order to maintain pressure uniformity.

A spray apparatus having built-in air regulation and a swivel connection to an air supply and uses thereof are described herein.

A spray nozzle, systems and methods for cleaning at least one optical fiber end face of an optical fiber connector. The nozzle includes a housing body with a first end portion and a second end portion. A discharge passage carries an atomized mixture of cleaning fluid and positively pressurized air from the first end portion to a discharge opening at the second end portion. A vacuum return passage communicates with the discharge passage proximate the second end portion. The return passage receives the atomized mixture of cleaning fluid and positively pressurized air as well as contaminants removed from the optical fiber end face. A portion of the atomized mixture of cleaning fluid and positively pressurized air is diverted from the discharge passage to control the amount of the atomized mixture being directed at the optical fiber end face.

A self-rotating device for cleaning with ultra-high water pressure having a base supported by front and rear wheels with a handle extending therefrom. A spray bar assembly with a plurality of nozzles constructed and arranged to cause rotation of the spray bar through fluid discharge is mounted beneath the base. A hydraulic pump is positioned with spray bar and coupled to a reservoir mounted on the handle. The hydraulic pump is rotated by the spray bar assembly, causing hydraulic fluid to recirculate through the reservoir, wherein an adjustable flow valve permits control of the spray bar assembly rotation speed.
