Abstract: Disclosed herein is an autonomous cleaning machine with a brush cleaning unit to clean a brush unit. The autonomous cleaning machine includes a main body, the brush unit rotatably provided on the main body, first brush cleaning members contacting the brush unit to move foreign substances wound on the brush unit in a lengthwise direction of the brush unit, and second brush cleaning members contacting the brush unit to remove the foreign substances wound on the brush unit from the brush unit.

Abstract: A surface cleaning apparatus with a removable compartment is provided that allows a dust cup in the removable compartment to be emptied while minimizing handling by the user. The removable compartment is removably secured within the surface cleaning apparatus. The removable compartment can be removed by activating a first trigger device. The dust cup can be emptied by activating a second trigger device.

Abstract: A light weight floor sweeper having a very low profile sweeper head that uses a sweeping brush and cleaning pad to slide across the surface to be cleaned. The floor sweeper head is mounted to an elongated handle by means of a universal pivot or universal joint which allows the floor sweeper head to easily pivot about the handle in any direction to pick up debris under over hanging cabinets or under furniture. A sweeping brush is mounted on the bottom of the sweeper head to provide sweeping action as the floor sweeper is moved in any direction. Furthermore there is a soft cleaning pad releasably mounted adjacent to the brush to entrap dust and particles that the brush does not pick up. The brush is powered by a small electric motor. A removable dust-receiving tray is mounted in the sweeper head to receive debris swept by the brush.

Abstract: The method of the present invention cleans abrasive faces of an upper abrasive plate and a lower abrasive plate of an abrasive machine. The method is executed by a cleaning device including: a nozzle for jetting water; a brush for preventing the jetted water from scattering in the air, the brush enclosing the nozzle; and another brush for closing a gap between the preventing brush and an outer edge of the upper abrasive plate, the method is characterized by the steps of: jetting water from the nozzle toward the abrasive face of the upper abrasive plate; moving the nozzle toward the outer edge of the upper abrasive plate; and closing the gap by the closing brush when the gap is formed between the preventing brush and the outer edge of the upper abrasive plate.

Abstract: A neural network integrated circuit comprises many neuron circuits each with a distance resister that is compared in a competition for the closest-hit with all the other neurons. Such closest-hit comparison is conducted bit-by-bit over the many bit positions of a distance measure in binary format each time after the neurons fire. A single-wire AND-bus interconnects every neuron in a whole system. Each neuron drives the single-wire AND-bus with an open-collector buffer. All neurons press the single-wire AND-bus with their respective distance measures in successive cycles, starting with the most significant bit. For example, a fourteen-bit binary distance word requires fourteen comparison cycles. Any neuron that sees a “0” on the single-wire AND-bus when its own corresponding bit in its distance measure is a “1”, automatically drops from the competition. By the time the least significant bit cycle is run, a single closest distance will have been determined.

Abstract: An adhesive roll cleaner (1) having single-sided adhesive sheets (3) helically wound around a core tube (2) with the adhesive side out, wherein the adhesive sheets (3) each have a tear strength of 500 mN or higher as measured with an Elmendorf tear tester according to JIS P8116(ISO 1974).

Abstract: In a cleaning device, the scraping up body and the rotating body rolling the adhesive roll are rotatably supported to the frame, and the adhesive roll is rotatably arranged on the scraping up body and the rotating body in parallel.

Abstract: A brush-type sweeper unit includes a prism-like body that has a base with an open front part, an open front face, and an upper face provided by a removable cap from which a handle for moving the sweeper unit extends. The body also includes parallel sidewalls between which first, second and third shafts extend, with the second shaft being between the first and third shafts. Front and rear cylindrical brushes are mounted on the respective first and second shafts, and a set of front wheels are also mounted on the first shaft at opposite ends thereof. Mounted on the third shaft are a set of rear wheels that are in edge-to-edge frictional engagement with a set of driven wheels on the second shaft. In this way the rear brush is driven by rotation of the rear wheels transmitted through the driven wheels, with rotation of the rear brush being in a direction opposite to the rotational direction of the front brush.

Abstract: The guard consists of an arcuate shaped trough member (6) which has a pad of absorbent material (7) fixed therein. The trough member (6) is mounted in a cradle (8) secured to a support member (9) fixed to a limb (4) of the paint roller assembly by a clamp (10). The arrangement being such that the spatter guard is spaced from but embraces part of the roller and is positioned between the roller and the roller handle.
