The present invention relates to a withdrawal plate suitable for an apparatus for withdrawing a sprayed paint to solve a failure of a painting facility and a contamination problem due to paint sludge, which includes: a square frame constituted by left and right side frames 91, an upper frame 92, and a base frame 93; and slats 94 arranged at a predetermined interval within the square frame, in which the left and right side frames 91 facing each other are included in one direction, and the slat 94 is fixed the left and right side frames 91 in an oblique state so that a front is lifted up and moves down backwards when viewed from the side, and multiple slats are consecutively arranged at a predetermined interval in a vertical direction.

A method includes rotating a substrate, supplying a first processing liquid from a first nozzle to the substrate during a first period, and supplying a second processing liquid from a second nozzle to the substrate during a second period. First and second liquid columns are formed by the first and second processing liquids during at least partially overlapped period of the first and second periods, respectively. The shapes and arrangements of the first and second liquid columns satisfy that: at least one of first and second central axis lines of the first and second liquid columns is inclined with respect to a rotational axis line of the substrate, first and second cut surfaces obtained by cutting the first and second liquid columns along a horizontal plane at least partially overlap each other, and any point on the first central axis line is located on the second central axis line.

An embodiment of the present invention discloses a polyimide coating method, which includes the following steps: providing a glass substrate and at least one nozzle; applying the nozzle to a polyimide solution onto the glass substrate to form a polyimide film; and moving the glass substrate to have the glass substrate pass through a roller that includes a printing plate so that the roller that includes the printing plate shapes the polyimide film uniformly distributed on the glass substrate to have a surface of the polyimide film formed on the glass substrate uniform and flat. The present invention also provides a polyimide coating device. The polyimide coating method and device of the present invention shorten coating time of polyimide, increase coating efficiency, and reduce coating cost.

Disclosed are a method and an apparatus for applying a liquid onto a substrate. The method for treating a substrate, the method includes: a liquid supplying step of supplying a treatment liquid for forming a liquid film on the substrate while rotating the substrate; and a liquid diffusing step of diffusing the treatment liquid discharged to the substrate by rotating the substrate, after the liquid supplying step. The liquid diffusing step includes: a primary diffusion step of rotating the substrate at a first diffusion speed; and a secondary diffusion step of rotating the substrate at a second diffusion speed, after the primary diffusion step. The second diffusion speed is higher than the first diffusion speed. Accordingly, the treatment liquid can be applied to the substrate again by performing the secondary diffusion step, making it possible to adjust the thickness of a photosensitive film.

An apparatus is disclosed that is designed to be able to clean HVAC condensers. The apparatus comprises a plurality of pipes that facilitates the passage of water through them allowing water and/or a cleaning solution to clean the condenser by spraying the condenser with sprayers without having to move the apparatus. The apparatus is designed so as to be able to spray every part of the condenser without having to move the apparatus. The apparatus may also have a timer associated with it that allows the condenser to be cleaned at periodic intervals.

A composition, device, and method for maintenance of railroad wood ties is presented herein. The device comprises a system for simultaneously filling rail spike holes in wood cross ties including a controlled system able to move in the x, y, and z planes. The system includes a product distribution box with multiple valves and dispensing lines for applying an environmentally friendly wood filler composition into multiple rail spike holes simultaneously. The wood filler composition is applicable for filling holes or gaps in wood to stabilize wood structures.

This solution is for painting the external walls of a building, and adopts a lightweight six axis robotic arm mounted on a mini-gondola hoisted by a pulley system with the controlling motor located within the mini-gondola, while another set of motor located on the pulley system at the roof-top end drives the mini-gondola to traverse laterally on a set of twin-rails on the roof-top of the building. Four vacuum suction cups mounted on the mini-gondola through linear actuator are used to secure the mini-gondola to the wall. Each linear actuator has three ultrasonic distance sensors that measure and manage the distance between the mini-gondola and the wall to be painted. Once the gondola is in position, the robotic arm will be activated to start the painting process.

Automated systems and methods of using a smart end-effector tool (20) including an applicator (30) to apply a coating onto an object surface (2) (e.g., a wind blade) are provided. The smart tool (20) can process on-board sensor signals and update its working state with a remote robot controller (28) in real time and send instructions to the robot controller (28) to adjust the tool's travelling around the object surface (2) and optimize the applicator's (30) operation.

A rinse arm system for a warewasher includes a rinse arm (1) rotatable about a rotation axis (D), a locking mechanism (2) connected to the rinse arm (1) such that the locking mechanism (2) is rotatable with respect to the rinse arm (1), and a bushing (3). The locking mechanism (2) is latched in an interlocking manner to the bushing (3) or clamped in a force-fitting manner to the bushing (3) such that the locking mechanism (2) is fixedly connected to the bushing (3) and the rinse arm (1) is rotatable about the rotation axis (D) with respect to the bushing (3).

A sealant discharging nozzle includes a nozzle body, a flat surface, a cutout, and a shaping portion. The flat surface is provided on the nozzle body and is formed on a discharge port side of a through hole that extends along a central axis of the nozzle body. The cutout is formed on a first side with respect to the flat surface. The shaping portion is, with respect to the flat surface, formed on a second side opposite to the first side.
