A substrate processing apparatus includes a driving magnet that is disposed correspondingly to a movable pin and that has a predetermined polar direction with respect to a radial direction of a rotary table, a pressing magnet that has a magnetic pole that gives an attractive magnetic force or a repulsive magnetic force between the driving magnet and the pressing magnet and that presses a support portion against a peripheral edge of a substrate by urging the support portion toward a contact position by means of the attractive magnetic force or the repulsive magnetic force, and a pressing-force changing unit that changes a magnitude of a pressing force against the peripheral edge of the substrate pressed by the support portion while keeping the magnitude higher than zero in response to rotation of the rotary table.

A decontamination apparatus for a viewing window includes a cylinder and a rotating module disposed at one end of the cylinder. The rotating module is connected with a viewing window. The rotating module can be driven to rotate, which further drives the viewing window to rotate for removing dirt attached to the viewing window. Besides, a decontamination apparatus for a viewing window includes a cylinder connected with a viewing window and a rotating module disposed at one end of the cylinder. The rotating module is connected with a wiper in contact with the viewing window. The rotating module can be driven to rotate, which further drives the wiper to turn for removing dirt attached to the viewing window.

Novel materials and devices can remove small defects from long rolls of flexible electronics material while they are in continuous motion. The cleaning materials are designed to remove small particles without transferring defects or damaging the flexible electronics. The device generally consists of variable speed, motor-driven cylinders mounted on moveable brackets. The cylinders are capable of matching the speed of the cleaning material such that the cleaning material is always in contact with the web roll to be cleaned. The brackets are capable of rotating so the same material can be used more than once. Another material is used to remove debris from the cleaning material. A similar device consisting of motor-driven cylinders and moveable is used to apply the debris removal film to the cleaning film, allowing the cleaning film to be used multiple times.

A rotary cleaning tool assembly for cleaning difficult to clean articles includes a housing that defines an interior space. A power module and a motor are coupled to the housing and are positioned in the interior space. The motor is operationally coupled to the power module. Each of a plurality of cleaning heads is selectively couplable to the housing so that the cleaning head is operationally coupled to the motor. The motor is positioned to rotate the cleaning head to clean an article.

An apparatus for cleaning an object, such as a two-wheeled vehicle, includes a housing that accommodates a cleaning device and has an open side on which the object and the housing can be positioned relative to one another and from which the cleaning device can be operated so as to act on the object. The cleaning device is provided with a control device for controlling the cleaning device. The apparatus allows objects, such as two-wheeled vehicles, to be cleaned in a simple manner while keeping costs, the amount of material used and energy consumption low.

The present invention is an automated wind turbine servicing system that includes a rover, and uses an active electro-mechanical gripping roller system to attach to the horizontally positioned airfoil and navigate along it in order to clean, inspect, service (paint, remove material or repair), or otherwise maintain the wind turbine airfoil. An electromechanical compression system adapts to various turbine airfoil profiles so that it can be used to service many different types of wind turbines. The rover operates on a horizontal airfoil rather than a vertical airfoil to utilize gravity and prevent movement along the chord of the airfoil. Once secured to the airfoil, the rover activates a drive system that propels the rover along the airfoil as it travels along the upper edge, using wind pressure, the rover wheels' frictional adherence to the airfoil, and gravity to assist in coupling the rover to the airfoil. The rover, which preferably includes a robotic arm, is able to utilize multiple tools to perform various tasks such as inspecting, cleaning, sanding, repairing, painting and laying leading edge protection tape as well as vortex generators on the surface of the airfoil.

It is an object to prevent adhesion of a processing liquid to a non-processing region of a substrate. In order to achieve the object, a substrate processing apparatus includes a substrate rotating mechanism, a discharging portion for discharging a processing liquid to a substrate, a moving portion for moving a discharging portion, and a controller. The discharging portion starts to discharge the processing liquid at a first position and is moved to a second position. The first position is a position of the discharging portion where a section of a passage of the discharging portion is projected onto a first region, and the second position is a position of the discharging portion where the section of the passage is projected onto a second region. The first region is a region on the peripheral edge side of the substrate from the second region.

Ladder cleaning device, particularly for use on ladders mounted on offshore installations, wherein the ladder cleaning device comprises: means for guiding and moving the device along the ladder means for detecting a ladder rung means for cleaning at least the detected rung.

An aircraft cleaning robot comprises a robot arm (14); a brush (34) rotatably attached to the robot arm (14) to be rotated about a brush rotation axis (R); and a controller (56) configured to control the position of the cleaning head (32), wherein the aircraft cleaning robot (10) is configured to automatically orient the brush (34) such that a cleaning face (37) of the cleaning head (32) is aligned with the surface being brushed; and the controller (56) is configured to, based on input from the robot arm (14) and/or cleaning head (32), determine a cleaning direction in which the cleaning face (37) is presently facing; and, based on the determined cleaning direction, operate the robot arm (14) along the cleaning direction to apply a brush engagement pressure in said cleaning direction.

The present invention relates to self powered and timer based solar panel cleaning system that is operated by self generating electrical power from solar energy and reduces wear and tear problem of moving parts. In this system, the microcontroller (54) is interfaced with motor driver (51) and brush driver (52). Said motor driver (51) and brush driver (52) control the speed of wheel motor (32) and brush driver (33). When ultrasonic sensor (5) sends signal to microcontroller (54), said microcontroller (54) generates and transmits signal to wheel motor driver (51) and brush driver (52). Thus, when structure reaches nearby the end edge of the solar panel array, said drivers gradually reduce r.p.m. of wheel motor (32) and brush motor (33) and then motors stop when machine reaches to opposite platform. Thus, during alteration of mode, r.p.m. of motors will be at substantially low that prevents the moving parts from damage.
