A wafer back surface cleaning device preventing foreign matter from re-adhering to front and back surfaces of a wafer W during and after cleaning. A hand H1 receives a wafer W that has been cleaned at a cleaning position and conveys the wafer W to a subsequent process, a hand H2 that conveys the wafer W before grinding to the cleaning position and transfers the wafer W that has been cleaned to hand H1 with a front surface of the wafer directed upward A cleaning pad 13 and a cleaning water supply nozzle 14 supplies cleaning water to the cleaning pad 13 and discharges the cleaning water to a back surface of the wafer W, at the cleaning position, the hand H2 brings the back surface of the wafer W conveyed to the cleaning position into contact with the cleaning pad 13 to perform scrub cleaning on the back surface of the wafer, and receives the cleaning water from the cleaning water supply nozzle 14 on the back surface of the wafer after scrub cleaning to perform rinse cleaning, and then transfers the wafer W to the hand H1.

A scraper sponge for cleaning and scraping away unwanted substances from an object or surface comprising a sponge body defining a first surface, a first layer, second layer, third layer, second surface opposite the first surface, a continuous side surface around the perimeter; and a scraper and scraper holder secured in an aperture defining the scraper holder approximately between the first surface and second surface of the sponge body. The scraper, after being inserted into the scraper holder has a tip portion extending outwardly from the scraper holder within the aperture within the sponge body and defining at least 5 edges and a depressible surface concave female groove to which forces are applied to manipulate the rigid scraper. The sponge body is usable with or without the scraper and has two surfaces available for cleaning and scouring; the first surface and second surface. The second layer, third layer, third surface, and continuous side surface are made of the same sponge-like cellulose material. As an alternative, the second layer, third layer, third surface, and a portion of the continuous side surface are not made of the same material and the sponge body has at least three surfaces adapted for cleaning and scouring; the first surface, second surface, and a portion of the continuous side surface. The sponge body is also usable with or without the scraper.

Inventive cleaning sheets contact the rollers of paper shredder autofeed mechanisms with cleaning material that is either moistened with a solvent or treated with a low tack adhesiveeither of which remove dirt and contaminants from the rollers. In one embodiment the moistened cleaning material is attached to a rigid sheet sized to fit into the paper compartment of the shredder where the cleaning material is brought into contact with the feed roller. The shredder is operated which causes dirt to be transferred from the rollers to the cleaning material. Alternatively, the cleaning material can be attached to a flexible but impermeable sheet which is placed into the shredder. The shredder is operated and after the rollers are cleaned, they may grab the entire flexible sheet and shred it, thereby additionally cleaning the shredding mechanism.

A substrate processing apparatus includes a substrate holder, a first cleaning body, a first moving mechanism, a second cleaning body, a second moving mechanism, and a controller. The first cleaning body cleans one of the upper surface and the lower surface of the substrate held by the substrate holder by ejecting fluid thereto or by coming into contact therewith. The second cleaning body cleans the other one of the upper surface and the lower surface of the substrate held by the substrate holder by coming into contact therewith. The controller controls the first moving mechanism and the second moving mechanism to perform a both-surface cleaning processing in which the first cleaning body which ejects the fluid to one surface or is in contact with the upper surface and the second cleaning body which is in contact with the lower surface are horizontally moved in synchronization with each other.

A cleaning member 10, for use in cleaning a substrate W, comprises: a tip surface 13 configured to be in contact with the substrate W when cleaning the substrate W, and the tip surface 13 being not covered with a skin layer 11; and a circumferential part having a covered part 16, which is disposed on the base end side and a circumferential surface of which is covered with the skin layer 11, and an exposed part 17, which is disposed on the tip end side and a circumferential surface of which is not covered with the skin layer 11.

A cleaning device for installation in a pipeline having a sensor unit which has at least one sensor tip; an elongated housing which has a first longitudinal end and a second longitudinal end and at least partially receives the sensor unit so that the sensor tip, in the measurement mode, protrudes at the second longitudinal end; and a wiping unit which is held in the housing so that it is movable in the longitudinal direction and has a wiping element, which is assigned to the sensor tip in such a way that the wiping element wipes along the sensor tip and thereby cleans it during a movement of the wiping unit.

An object of the present disclosure is to provide an optical connector cleaning tool capable of cleaning a ferrule end surface with an appropriate force regardless of an operator.

The present disclosure is an optical connector cleaning tool including a housing that stores a cleaning sheet, an opening portion through which a part of the cleaning sheet is exposed from the housing, a slide mechanism that causes the cleaning sheet exposed to the opening portion to slide, a cleaning sheet support portion that is fixed to the housing and supports the cleaning sheet toward the opening portion, a plug holding unit that holds an optical connector plug having a ferrule disposed at a distal end thereof at the opening portion, and a pressing portion that applies a pressing force between the cleaning sheet support portion and the plug holding unit.

A lens and/or a view screen of an electronic device having at least one case can be cleaned by wiping the view screen with a cleaning component wherein the cleaning component is configured to selectively couple to the at least one case or some other substrate using a magnetic attractive force. The cleaning devices may have secondary applications such as securing fly fishing lures, activating or deactivating a device having a magnetic switch, or preventing sunglasses from sinking. They may also be manufactured without a cleaning component for use with the secondary applications.

A substrate cleaning device includes: a pressing member that cleans a substrate by contacting the substrate; a load measurement unit that measures a pressing load of the cleaning member; and a control unit that repeats an operation of comparing the measurement value of the load measurement unit with the setting load, changing the pressing amount of the cleaning member by a first movement amount so that a difference value decreases, when the difference value is larger than a first threshold value and equal to or smaller than a second threshold value, and changing the pressing amount of the cleaning member by a second movement amount larger than the first movement amount so that the difference value decreases, when the difference value is larger than the second threshold value, until the difference value becomes equal to or smaller than the first threshold value.
