2648 results about "Scratching" patented technology

Scratching, sometimes referred to as scrubbing, is a DJ and turntablist technique of moving a vinyl record back and forth on a turntable to produce percussive or rhythmic sounds. A crossfader on a DJ mixer may be used to fade between two records simultaneously.

Belt assembly for storage and inventory of tools

A tool-carrying assembly to be secured by a waist-encircling belt, and, additionally, by straps encircling the legs of a workman using the belt assembly. The assembly is thus stabilized, and enhanced weight distribution is achieved. Elements of the belt assembly include a waist-encircling band supporting a pair of laterally spaced, depending panels each carrying tool-accepting pockets. The pockets preferably carry visual markings and coding as well as other indicia identifying clearly the specific tools to be "housed" or carried in and to be returned to each pocket after use. Inventory control of the tools is thereby significantly enhanced. Pivotal flaps depending from the band-carried panels serve to cover the tools when not in use, and to prevent the tools from scratching or otherwise marring any article, or fixture, or "workpiece" requiring the workman's attention. The panels and the tools carried thereby are disposed in lateral, spaced zones at the wearer's sides (and not directly in the front of one's body) thus further to reduce any likelihood of the tools coming into damaging physical contact with an article being worked upon. That is, both frontal and rearwardly located zones about the wearer of the tool belt assembly are rendered essentially free and clear of all tools and other mechanical impediments. While wearing the tool assembly of the invention, a worker can, without any discomfort, lie upon and use a "creeper". Significantly, a frontal sector of the belt itself is covered with a relatively soft, non-marring protective pad, composition, or surface material effective to prevent possible damage from a workman's belt buckle. An additional feature of the invention is that the panels may be structured to constitute a core sandwiched between a pair of encasing sheet-like webs. The resulting composite is readily formable to provide selectable visual patterns, designs or indicia, for example, to identify product name or sources and / or to constitute decorations.

Micron-nano scale in-situ nano indentation and scratching test system

The invention relates to a micron-nano scale in-situ nano indentation and scratching test system which integrates driving, precise loading and signal detection, micron-nano scale mechanics performance testing, ultraprecise scratching processing and high resolution in-situ observing as one. The system is mainly composed of a precise positioning platform at X-axis and Y-axis directions, a precise linear positioning platform at Z-axis direction, a precise indentation driving unit, a load signal and displacement signal detection unit and a high resolution digital microscopic imaging system for observing and storing material deformation and damage conditions in the test process. The precise positioning platform at the X-axis and Y-axis directions is assembled on a base, the precise linear positioning platform at the Z-axis direction is assembled on a side plate, the precise indentation driving unit, a precise mechanical sensor for detecting the indentation material pressure of a diamond tool head and a precise displacement sensor for detecting the indentation depth of the diamond tool head to along the Z-axis direction are assembled on the precise linear positioning platform at the Z-axis direction, and the high resolution digital microscopic imaging system is assembled on a beam.

Method and apparatus for alignment of automated workpiece handling systems

InactiveUS20020021959A1Facilitate accurately levelingBreakage can be reduced eliminatedDigital data processing detailsSemiconductor/solid-state device manufacturingDisplay deviceHandling system
An alignment tool, method and system are provided for aligning a robot blade in a workpiece handling system, in which the tool comprises a frame or fixture adapted to be supported by a transfer chamber support surface or other support surface in the system, in which the frame has one or more non-contact distance sensors positioned to measure the distance of a workpiece or robot blade from the sensor or a predetermined reference point or surface. In one embodiment, the frame is used to align a robot blade relative to a robot support alignment surface in a robot chamber. In another embodiment, the frame emulates a workpiece cassette and the distance sensors provide an output to align the robot blade to a cassette support alignment surface. As a consequence, accidental scratching and breakage of workpieces such as semiconductor wafers and display substrates may be reduced or eliminated. In another embodiment, positions of distance sensors may be readily repositioned to accommodate alignment procedures for different sized wafers or other workpieces.
