Specifically, a panel module including a first frame including a first plurality of frame members joined to enclose a first panel. The first plurality of frame members including a first frame inner side configured to capture the first panel within the first frame and a first frame outer side configured to provide a first track axially extending between first and second ends of at least one of the first plurality of frame members. The first track configured to engage a drive element of a panel maintenance assembly which operates to move the panel maintenance assembly over the first panel. The panel maintenance assembly bears one or more components which function to maintain the first panel.

A wet vacuum assembly and suction head combination assembly for dislodging and cleaning landscaping materials, such as landscape rock includes a wet vacuum assembly and a suction head. The wet vacuum assembly generates an airflow through a tube thereof. The suction head is engaged to the tube distal from the wet vacuum assembly so that an interior space, which is defined by the suction head, is in fluidic communication with the tube. The suction head has an opening positioned in a bottom thereof. A set of nozzles is coupled to a top of the suction head and is engageable a hose, which extends from a source of pressurized water. The nozzles direct a spray of water from the hose through the interior space to dislodge objects, such as landscape rock embedded in a surface, and to clean the objects that now are entrained in the airflow.

Spray apparatus and uses thereof are described herein. A vacuum spray nozzle apparatus may include a first tube in fluid communication with a fluid source, a rotor coupled to the tube, a conduit in fluid communication with the passages of the first tube, and a second tube coupled to the conduit, the second tube being in fluid communication with a vacuum source. The rotor is in fluid communication with the pressurized fluid source. The conduit is substantially arched or angled such that an outlet of the conduit is offset a radial distance in a radial direction from the rotor axis, and when pressurized fluid is ejected from the outlet, during use, rotates the conduit. The vacuum spray nozzle apparatus is configured to remove components from a material through the second tube when a pressure of the system is reduced using the vacuum source.

A substrate treating apparatus is disclosed. The apparatus may include a housing including an upper body and a lower body coupled to each other to define a treatment space, the lower body being provided below the upper body, a supporting unit coupled to the upper body, the supporting unit supporting an edge of a substrate disposed in the treatment space, a fluid supplying unit configured to supply fluid into the treatment space, a sealing member provided between and in contact with the upper and lower bodies, the sealing member hermetically isolating the treatment space from an outer space, and an isolation plate installed between the sealing member and the supporting unit. The isolation plate may be provided to face the sealing member.

A substrate processing apparatus includes a stationary cup body 51 provided to surround a substrate holding unit 31 and configured to receive a processing liquid or mist of the processing liquid discharged onto a substrate, the stationary cup body not being moved relatively with respect to a processing vessel; a mist guard 80; and a guard elevating mechanism 84 configured to elevate the mist guard. Here, the mist guard is provided at an outside of the stationary cup body to surround the stationary cup body and configured to block a liquid scattered outwards beyond a space above the stationary cup body. Further, the mist guard includes a cylindrical portion 81 of a cylindrical shape and a protruding portion 82 protruded from an upper portion of the cylindrical portion toward an inside of the cylindrical portion.

A substrate processing apparatus includes a rotation holding device that holds and rotates a substrate, a liquid supply device including one or more rinse liquid nozzles that are positioned on back surface side of the substrate and supply rinse liquid to peripheral edge portion of back surface of the substrate, a cup that receives the liquid supplied to the substrate, and a control device including circuitry that controls the holding and supply devices. The nozzle is attached to the cup to receive the liquid, and the circuitry controls the holding and supply devices and executes first process in which the holding device varies rotation speed between first and second speeds, and the nozzle supplies the liquid to the peripheral edge portion of the back surface of the substrate such that the liquid cleans peripheral region of the nozzle in the cup and region on outer side of the peripheral region.

Generally, a panel maintenance system including a panel maintenance assembly configured to move over a plurality of panel modules. Specifically, a panel module including a first frame including a first plurality of frame members joined to enclose a first panel. The first plurality of frame members including a first frame inner side configured to capture the first panel within the first frame and a first frame outer side configured to provide a first track axially extending between first and second ends of at least one of the first plurality of frame members. The first track configured to engage a drive element of a panel maintenance assembly which operates to move the panel maintenance assembly over the first panel. The panel maintenance assembly bears one or more components which function to maintain the first panel.

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 mobile robot having a main chassis supporting a headpiece for cleaning, stripping, reconditioning or refurbishing a coating on a metal work piece. A remote controlled power module allows for locomotion of the chassis which is held to the work piece by magnets spaced apart from the work piece by a predetermined space. The chassis provides operational control of a headpiece capable of unique positioning that is possible in view of the separated chassis and headpiece combination.
