Abstract: The present invention provides an antifouling ability-imparting agent that adheres well to a variety of water treatment membranes such as reverse osmosis membranes and imparts excellent antifouling ability to the water treatment membranes.

Abstract: An autonomous traveling floor cleaner is disclosed that improves cleaning efficiency. A floor cleaner may include a suction nozzle that suctions suction matter collected by a rotary brush, an extension nozzle that suctions suction matter collected by an extension brush, and a collection box for collecting, through an inlet, the suction matter suctioned by the nozzles. The floor cleaner may have an elongated profile. The extension nozzle may be switchable between a retracted posture and a lateral cleaning posture. The extension nozzle in the lateral cleaning posture may be pivotable rearward. The extension nozzle in the lateral cleaning posture may have a protruding end in the width direction to be aligned with an end of a turning range of the floor cleaner in the width direction.

Abstract: A floor surface cleaning apparatus according to one or more embodiments may include a water collecting nozzle, rotating brushes that may retain water, and a water collecting box that has a pooling portion in which wastewater may be pooled. In response to the rotating brushes being rotationally driven, wastewater on the floor surface is absorbed and retained by the rotating brushes, and the wastewater retained in the rotating brushes may be made into a mist and flung upwards by a centrifugal force generated by rotation of the rotating brushes and passed through an opening and a suction port and pooled in the pooling portion in the water collecting box.

Abstract: A lever-type connector (10) has a housing (60) for engaging a mating connector (80). A lever (20) is supported rotatably by the housing (60) and is configured for assisting connection of the connectors (10, 80). The lever (20) has a lever-locking part (31) with a deformable elastic piece (33). A lock (35) on the elastic piece (33) engages a receiving portion (72) on the housing (60) for holding the lever (20) in a rotation-prevented state. A release portion (41) formed separately from the lever-locking part (31) can be pressed to displace the elastic piece (33) in a direction for separating the lock (35) from the receiving portion (72).

Abstract: An apparatus having a pushing tray in a note storage compartment. The pushing tray moves downwardly to provide enough space to store notes smoothly. During a delivery operation, a gate lever compresses the stored notes to a predetermined pressure against the pushing tray, allowing the stored notes, even crumpled, to be delivered smoothly one after another.
