A synthetic polymer film (34A), (34B) having a surface which has a plurality of first raised portions (34Ap), (34Bp), wherein a two-dimensional size of the plurality of first raised portions (34Ap), (34Bp) is in a range of more than 20 nm and less than 500 nm when viewed in a normal direction of the synthetic polymer film (34A), (34B); and the surface has a microbicidal effect.

An awning cleaning tool for cleaning awnings and other structures employing awning-like material. In one implementation, the awning cleaning tool includes a cleaning head unit having a squeegee-like leak guard, one or more powered brushes, a row of water-detergent applicator nozzles, and an elongated extraction port. The awning cleaning tool also includes an elongated extension and a control handle. During cleaning, a water-detergent mixture is sprayed via the nozzles onto the top surface of the awning and the powered brushes work the water-detergent mixture into the material of the awning to dislodge the dirt and debris. The used water-detergent mixture, dirt and debris are extracted via the extraction port. Any excess water-detergent mixture is captured by the leak guard so that it does not run down and off the awning.

A hydraulic arrangement (HA) for an apparatus (AV) for deblocking optical workpieces (L), from associated block pieces (B), includes a nozzle arrangement (DA) for delivery of high pressure jets of pressure means for deblocking the workpiece from the associated block piece at a first pressure and for cleaning the blocked workpiece and/or block piece at least one second pressure which is different from the first pressure. Furthermore, there is a pump device (PE) which applies pressure in a defined manner to the pressure means and conveys it under pressure to the nozzle arrangement. The pump device has at least one high pressure pump (HP1, HP2) which is drivable by an associated rotary drive (SM1, SM2), the speed of which is modifiable in order to adjust the first pressure or the second pressure.

A dust removal device capable of normally dedusting a surface of a sheet-shaped object having an edge portion of a shape with protruding parts continuously arranged at predetermined intervals along the longitudinal direction, that is, a dust removal device discharging a gas to a surface of a sheet-shaped object 100 from a discharge outlet while drawing in the gas above the surface of the sheet-shaped object 100 through a suction inlet, the discharge outlet including a first discharge outlet 30 for discharging the gas to portions of the sheet-shaped object 100 other than the edge portion and a second discharge outlet 35 for discharging the gas to the edge portion 100b of the sheet-shaped object 10, and the suction inlet including a first suction inlet (31, 32) for drawing in the gas above the surface of the portions of the sheet-shaped object 100 other than the edge portion 100b and a second suction inlet (33, 34) for drawing in the gas of the surface of the edge portion 100b of the sheet-shaped object 100.

A cleaning device (10, 110, 210) may be a card-like member such as a flap (16, 116), integrally formed with a dispenser container (12), or a slotted member (36) mounted on a stand-alone cleaning device (110). A cleaning wipe fabric (22, 122) has a modulus of stiffness which is high enough to bridge a plurality of cleaning slots (26a-26d, 126a-126d) and hold the fabric out of contact with the slot floor surfaces (26a′), and low enough to be deflected by a fiber optic end being cleaned to sag within the cleaning slot to better enclose and clean the tip of the fiber optic end. Used cleaning fabric (22, 122) can easily be advanced or removed as needed to avoid using the same area of fabric for cleaning more than once.

An apparatus for treating optical fibers can be used to carry out necessary cleaning work on the end tips of the glass fibers of fiber-optic cables. The apparatus has modules which are provided with non-abrasive surface layers able to pick up contaminants and are spring-mounted in relation to one another such that they can be pivoted about a hinge joint, and, in the case of at least one of the modules, elastic material layers are introduced between the surface layer and the main body of the assembly. The assemblies are preferably designed in the form of grip plates, between which non-abrasive, cloth-like layers are applied, as a cleaning surface, to each of the facing surfaces and, in the case of both gripping plates, elastic insulating materials are arranged between the cloth-like surface layer and the gripping plate.
