Abstract: A calibration device for a pad conditioner head of a CMP machine includes a lower first horizontal member defining an arcuate reference surface having a shape complementary to that of the outer peripheral edge of the platen of the machine, an upper second horizontal member spaced vertically from the first member and having a reference mark thereon lying in the projected plane of the reference surface, and a connecting member interconnecting the first member and second member. When the reference surface of the first horizontal member of the calibration device is be butted against the outer peripheral edge of the platen adjacent the head of the pad conditioner, the location of the outermost portion of the head of the pad conditioner relative to the reference mark is readily observable. Thus, the extent to which the outermost portion of the head of the pad conditioner is vertically aligned relative to the outer peripheral edge of the platen can be easily and accurately determined.

Abstract: A safety ruler and guide used with a rotary cutter or the cutting tool for cutting fabric, the ruler designed to protect a user's first hand when holding the ruler on top of the fabric while the second hand is cutting the fabric with the cutting tool. The ruler has a vertical guard mounted exactly upright to a base guide, dividing the base equally into a first side and a second side. Each first side and second side display grids, ruler measurements and measuring scale to enable a right or left handed user to properly read and measure length and width of the fabric being cut. The first side and second side also include a ruler edge for measuring the length of fabric being cut, and serving as a guide and cutting edge for the rotary cutter. The user may then cut the fabric using the cutting tool without the cutting tool or fabric moving during cutting. In the event the cutting tool slips while cutting, the hand holding and applying pressure to the ruler is protected by the vertical guard.
