Abstract: An apparatus and method for sequential application of cleaning fluids for improved maintenance of chemical mechanical polishing (CMP) systems is disclosed. A method includes transferring a first substrate to a first polishing station of a plurality of polishing stations, polishing the first substrate at the first polishing station, transferring the first substrate to a second polishing station, and transferring a second substrate to the first polishing station. The method includes cleaning a first surface of a plurality of surfaces of the polishing system by dispensing a first cleaning fluid from a first one or more nozzles of a plurality of nozzles to direct the first cleaning fluid onto the first surface and dispensing a second cleaning fluid from the first one or more nozzles to direct the second cleaning fluid onto the first surface, where the second cleaning fluid is different from the first cleaning fluid.

Abstract: Hand-guided treatment device for walkable surfaces adapted to clean, sanitize and dry such surfaces, including a guiding body joined below, through an articulated element to a unit for cleaning, sanitizing and drying such surfaces, the guiding body having housed inside it at least a control and command electronic circuit board powered by at least an electrical transformer, at least a first reservoir and at least an electrical pump. The unit has component elements assembly inserted into a stiff and shell-shaped casing, this latter being opened on its lower part and provided at its lower part with at least a free wheel, for moving the device, and being provided on its upper part with an upper opening, in correspondence of the articulated element, adapted to connect the component elements of the guiding body and component elements assembly.

Abstract: A system for polishing a sample is provided. The system may comprise a motor. The system may also include a polishing element that is actuated by the motor. The system may also have a sample holder. The sample holder may hold a sample to be polished by the polishing element. In some examples, the sample holder has multiple degrees of movement in order to precisely polish, grind, or bevel the sample. In some examples, the system may further include an arm having a slurry dispenser, inlets for fluid, and a squeegee-like element to clean, wash, or brush off debris from the polishing element during a polishing process.

Abstract: A cleaning robot include a main body and a cleaning module. The cleaning module includes a box body, at least one driving mechanism, and at least one rotating plate assembly. The box body includes a first connector. The at least one driving mechanism is positioned on a bottom surface of the box body, electrically connected to the first connector, and includes at least one drive shaft. Each rotating plate assembly is connected to a corresponding drive shaft and includes a cleaning surface. The cleaning surface is configured to rotate under the drive of the corresponding drive shaft to clean a to-be cleaned surface. The main body includes a second connector. The box body is detachably positioned on the main body, such that the first connector is connected to or disconnected to the second connector.

Abstract: The invention relates to hand tools of knife sharpening, especially for sharpening of kitchen knifes, namely relates to angle guides for knife sharpening. This angle guide has a removably attachable body that is put on a sharpening rod through a hole going through the body, which has the ability to move back and forth on the rod. The body has guiding cutouts for the blade of a knife that allow to maintain the desired angle against the sharpening rod during the sharpening procedure. At least one pair of cutouts with inclined narrowing cavities are formed in the body on its opposing sides in opposing directions, which allows to alternate between the sides of the blade during the sharpening process and in this way much less burr is produced.

Abstract: A vise having a modular construction that allows for ease of manufacture, assembly, and changeover or replacement of wear items, such as gripping surfaces of jaws of the vise. The modular construction also provides for reduced weight of the vise compared to conventional cast type vises. The vise also incorporates quick adjustment features allowing for the vise to be easily rotated, a position and size of an opening of the jaws to be rapidly adjusted, and a clamping force applied with ease.

Abstract: Some embodiments of the present disclosure provide an adjustable torque clamping fixture, including a clamping body driven by a threaded rod to move and used for clamping an object. The threaded rods implements an axial movement thereof by means of screw thread transmission. An adjustable torque handle is configured at the rear end of the threaded rod. The maximum clamping force is adjusted by the adjustable torque handle. When the maximum clamping force is attained, continued application of a torque on the threaded rod by the handle results in slippage, so that no larger clamping force can be applied, thus implementing precision clamping, and preventing the clamped object from being damaged by an excessive torque. The adjustable torque clamping fixture overcomes the shortcoming of a manual clamping fixture known to inventors of which the magnitude of the clamping force is difficult to determine during use.

Abstract: A pallet clamp includes a clamp receiver 110 and a clamp 130. The clamp receiver 110 has an abutted surface 111 with serrations, whereas the clamp 130 has an abutting surface 132 with serrations. The clamp receiver 110 has both of a pressed surface 180 and a counter pressed surface 181 which face in directions perpendicular to the direction along the extension of the serrations. A biasing means 150 press-fits the clamp receiver 110 and the clamp 130 to each other so that the abutting surface 132 and the abutted surface 111 come into tight contact with each other, which causes the pressed surface 180 and the counter pressed surface 181 to be pressed in opposite directions.
