Abstract: A multifunctional push-pull mop includes a base plate, a support member, and an elastic member. A user can bring the base plate to which a cleaning cloth is attached into close contact with a floor, a wall, a ceiling, or the like, using a small force, and when the user moves the base plate to which the cleaning cloth is attached from a boundary portion between a floor and a wall or between a wall and a ceiling to the floor, wall, or ceiling, the base plate can be rotated by the elastic restoration force of the elastic member to instantly come into close contact with the floor, wall, or ceiling, thereby allowing the user to conveniently move the base plate from the boundary portion of the floor, the wall, the ceiling, or the like, without detaching the base plate therefrom.

Abstract: Embodiments herein generally relate to polishing pads and method of forming polishing pads. In one embodiment, a polishing pad having a polishing surface that is configured to polish a surface of a substrate is provided. The polishing pad includes a polishing layer. At least a portion of the polishing layer comprises a continuous phase of polishing material featuring a plurality of first regions having a first pore-feature density and a plurality of second regions having a second pore-feature density that is different from the first pore-feature density. The plurality of first regions are distributed in a pattern in an X-Y plane of the polishing pad in a side-by-side arrangement with the plurality of second regions and individual portions or ones of the plurality of first regions are interposed between individual portions or ones of the plurality of second regions.

Abstract: A chemical mechanical polishing system includes a steam generator with a heating element to apply heat to a vessel to generate steam, an opening to deliver steam onto a polishing pad, a first valve in a fluid line between the opening and the vessel, a sensor to monitor a steam parameter, and a control system. The control system causes the valve to open and close in accordance with a steam delivery schedule in a recipe, receive a measured value for the steam parameter from the sensor, receive a target value for the steam parameter, and perform a proportional integral derivative control algorithm with the target value and measured value as inputs so as to control the first valve and/or a second pressure release valve and/or the heating element such that the measured value reaches the target value substantially just before the valve is opened according to the steam delivery schedule.

Abstract: An autonomous cleaning robot includes a drive system to move the autonomous cleaning robot about a floor surface in a space, a cleaning system to clean a floor surface in the space as the drive system moves the autonomous cleaning robot about the floor surface, and a controller configured to execute instructions to perform one or more operations.

Abstract: A grinding apparatus includes a chuck table that holds a workpiece through a protective tape, where the protective tape is attached to one surface of an annular frame so as to cover an opening of the annular frame and the workpiece is attached to the protective tape on an inner side of an inner circumferential edge of the opening of the annular frame; a grinding unit for grinding the workpiece; and a frame cleaning unit that cleans the other surface located on a side opposite to the one surface of the annular frame obtained after grinding of the workpiece, and wherein the frame cleaning unit has either: (i) a first cleaning member configured and arranged for making contact with the other surface of the annular frame and having flexibility, or (ii) a second cleaning member that jets at least either gas or liquid from above the other surface of the annular frame.

Abstract: A ratchet wrench handle includes an operation piece which is composed of two partial members including a claw member and a receiving member. The ratchet wrench handle is configured such that, when positive rotation-aimed operation teeth of the claw member are engaged with ratchet teeth of a rotation member, a wedge effect produced by the positive rotation-aimed operation teeth of the claw member and a positive rotation-aimed sloping face of the claw member is configured to make the rotation member stop rotation, which allows an adapter to be rotated in a positive direction.

Abstract: A paint-line hook for vehicle shocks includes a tube, an eye fixed to the tube, and a bracket fixed to the tube below the eye. The tube has a bottom end and a bore extending through the bottom end. The bracket defines a channel configured to engage a mount of a vehicle shock. A latch is rotatably supported by the tube. The tube includes a slot in communication with the bore. The latch extends through the slot and has a handle exterior to the slot and an end positioned to engage a threaded shaft of a vehicle shock in the bore. A vehicle shock may be retained in the tube and the tube acts as a paint shield during paint application to the vehicle shock.
