Abstract: Disclosed is a cleaning robot having an improved driving and cleaning ability. The cleaning robot includes a dust collecting blade. A lower end of the dust collecting blade is bent in a direction opposite to the driving direction of the cleaning robot during operation of the cleaning robot, so that wobbling is not generated even though the ground surface on which the cleaning robot operates has bumps and gaps.

Abstract: In a method of cleaning a photomask, a wiper tape is guided from a wiper tape supplying reel, over a cleaning head, and then onto a wiper tape collecting reel. A section of the wiper tape over the cleaning head is brought into contact with an adhesive residue on a surface of the photomask. A relative movement is caused between the photomask and the section of the wiper tape to remove the adhesive residue from the surface of the photomask.

Abstract: A pipeline pig includes a plurality of relief channels and a bypass channel extending therethrough. To regulate a speed of the pipeline pig, relief valves within the relief channels open when a differential pressure between upstream and downstream ends of the pipeline pig reaches a pre-selected minimum relief pressure. If the differential pressure reaches a pre-selected maximum relief pressure, such as when the pipeline pig encounters an obstruction, the relief valves close to allow the differential pressure to further increase to clear the obstruction. If the further increase in differential pressure is insufficient to clear the obstruction and the differential pressure reaches a pre-selected minimum bypass pressure, a bypass valve opens to permit fluid flow through the bypass channel while the relief valves are closed. Flow through the bypass channel operates to reduce turbulence and permit production through the pipeline if the pipeline pig becomes stuck and obstructs the pipeline.
