A cleaning device for use with an atomizer that applies paint to the surface of a component in a spray booth includes an external and internal surface in which a least a portion of one or more of the surfaces are coated with a conductive coating. This conductive coating comprises one or more fluoropolymers and may be static dissipative. The cleaning device further includes an exit port that has an aperture between about 2.54-7.62 cm located in the shroud of the device opposite the opening that receives the atomizer and near a bottom corner of the shroud. A kit used to retrofit existing paint spraying systems includes a fully assembled cleaning device and optionally, a regulator assembly capable of reducing the pressure of a cleaning fluid to about 80 psi. During installation, the regulator assembly is mounted external to the spray booth.

Embodiments of the invention provide a push valve assembly. The push valve assembly includes a valve piston that is movable within a valve body between a fully opened position and a fully closed position, passing through an intermediate rinsing position, to selectively provide pressurized fluid through flow paths defined by the position of the valve piston.

A slit nozzle is moved by a nozzle lifting/lowering mechanism and a nozzle sliding mechanism relative to substrates held in a substantially horizontal attitude by spin chucks. A development liquid is discharged on each substrate from a discharge port of the slit nozzle such that development processing for the substrate is performed. After the development liquid is discharged, the slit nozzle is moved to a waiting position excluding positions over the substrates held by the spin chucks. In waiting pods provided at the waiting positions, cleaning processing for the slit nozzle is performed by a cleaning liquid with gas bubbles mixed therein.

Provided is a sample pretreatment device configured to apply, to the surface of a sample, a solution in which a predetermined substance is dissolved or dispersed. In order to properly and efficiently unclog a nozzle due to the deposition of the crystal of a matrix substance, the device includes a spray unit (3) including a solution tube (32) for the solution to pass through, a gas tube (33) for a spray gas to pass through, and a nozzle part (30) configured to spray the solution arriving at the terminal end of the solution tube by ejection of the spray gas through the gas tube, as well as a cleaning liquid supplier (4, 41) configured to put a cleaning liquid on an opening of the nozzle part from outside the spray unit.

A sanitary washing device includes a nozzle, a drive device, a casing, a nozzle lid, and an illuminator. The casing includes a nozzle container. The nozzle lid is provided to be openable and closable with respect to an opening provided at a front end of the nozzle container. The nozzle lid is in a closed state in which the opening is closed when the entirety of the nozzle is stored in the nozzle container. The illuminator irradiates sterilizing light into an interior of the nozzle container. The sterilizing light has a sterilizing effect. At least one of the nozzle lid or a vicinity of the nozzle lid is luminous in a state of being visible to the user when the nozzle lid is in the closed state and the sterilizing light from the illuminator is irradiated into the interior of the nozzle container.
