The present invention relates to a substrate cleaning apparatus and a substrate cleaning method for cleaning a substrate, such as a semiconductor wafer, and more particularly to a substrate cleaning apparatus and a substrate cleaning method for cleaning a periphery of a substrate. A substrate cleaning apparatus (1) includes: a substrate holder (10) configured to hold and rotate a substrate (W); a pressing structure (22) having an internal space (R) and configured to press a cleaning tape (19) against a periphery of the substrate (W); a pressing-structure moving mechanism (30) configured to regulate a position of the pressing structure (22) in a radial direction of the substrate (W); and a pressure regulator (44) configured to regulate pressure in the internal space (R). The pressing structure (22) includes: a hollow support member (24) having an opening (25); and an elastic element (27) configured to support the cleaning tape (19). The elastic element (27) is arranged to close the opening (25).

A vacuum cleaner includes a main body including a fan, a motor connected to the fan, and configured to rotate the fan to generate an intake force, and an intake head connected to the main body to guide foreign substances to be drawn into the main body therethrough by the intake force. The intake head includes a housing including an inlet, a drum brush rotatable within the housing to allow the foreign substances to be drawn into the housing through the inlet, and the drum brush including a drum body and a brush on an outer circumference of the drum body, and a cutter adjacent to the brush and including a plurality of cutting edges arranged along an axial direction of the drum brush to allow the foreign substances wound on the drum brush to be cut and removed from the drum brush.

A collection kit for the removal of unwanted material from a surface, said kit comprising: iv) ferromagnetic material to absorb and/or adsorb the unwanted material when spread across the unwanted material creating an area of operation; v) an apparatus having a magnetic source operable to attract the ferromagnetic material together with absorbed and/or adsorbed unwanted material when the magnetic source is touching or in the vicinity of the area of operation; and vi) means to dislodge the ferromagnetic material and absorbed and/or adsorbed unwanted material from the apparatus once the ferromagnetic material has been removed from the area of operation.

A cleaning system comprises a first cleaning tank, a carrying and moving unit, a first cleaning spray head, and a rolling brush unit. The carrying and moving unit is configured to move a polishing film to be cleaned into the first cleaning tank and hold the polishing film in the first cleaning tank. The first cleaning spray head is configured to spray a cleaning liquid on the polishing film held in the first cleaning tank. The rolling brush unit is configured to brush the polishing film while the first cleaning spray head sprays the cleaning liquid on the polishing film.

A self-cleaning device of the present disclosure includes: a cleaning member configured to clean a cleaning tool that cleans a substrate; and an injection unit configured to inject a liquid toward the cleaning member or the cleaning tool. The cleaning member has a cleaning surface that cleans the cleaning tool when the cleaning tool is pressed thereagainst, and the cleaning surface is inclined with respect to a horizontal plane.

A waste removal and transfer assembly for a 3D printing system comprises a waste material remover and a waste material collector. The waste material remover comprises a movable waste removing element selectively movable into contact with a planerizer roller to remove 3D printing waste material from the planerizer roller. The waste material remover is coupled to translate with the planerizer roller and comprises an opening leading to a waste material receptacle configured to receive waste material and at least one port selectively operable to transfer waste material from the waste receptacle. The waste material collector has a receiving position that is stationary relative to the waste material remover. The waste material collector comprises an opening and a waste material storage recess to receive waste material transferred from the waste material remover via the at least one port and to store the received waste material for subsequent disposal.

A filter cleaning device has an improved structure which is capable of effectively cleaning dust in a filter used in an air conditioner. The filter cleaning device includes: a filter; a brush unit movably installed at one side of the filter to separate dust from the filter; a brush movement unit configured so that the brush unit is movable along the filter; and brush guides installed at two sides of the brush unit to guide a movement of the brush unit. Each of the brush guides includes: a first guide groove formed so that the brush unit is moved to be in contact with the filter; and a second guide groove formed so that the brush unit is moved to be separated from the filter.

Described herein is a system for the preparation of a filled biscuit, including: a forming unit for forming biscuit bodies in series, with a biscuit dough; a conveying system for feeding the biscuit bodies along a production path; an oven for baking the biscuit bodies, which is traversed by the conveying system and is configured to subject the biscuit bodies to a baking process, while the biscuit bodies are fed along the conveying system; and an injection unit, which is set downstream of the oven with reference to the production path and includes a plurality of needles for injecting a filling simultaneously into a plurality of the biscuit bodies arranged on the conveying system.
