A movable clipper blade is defined adjacent to front and rear ends thereof with front and rear oil passages and is positioned underneath the oil pad, such that the front and rear oil passages are communicated with oil storing grooves defined on a lower surface of the movable clipper blade, to supply oil between the movable clipper blade and a fixed clipper blade.

Abstract: Apparatus for detecting a defect in the outer peripheral edge of a wafer includes a rotary mechanism by which the wafer can be rotated, a wafer edge contact device, and a controller. The wafer edge contact device includes a string that is pressed against the edge of the wafer. One end of the string is fixed in place, and a sensor is operatively associated with the other end of the string so as to sense movement of the other end of the string. This other end of the string will be pulled by a defect at the outer peripheral edge of the wafer when the wafer is rotated. Thus, a defective edge of the wafer can be detected before/after the wafer is processed. Accordingly, the wafer can be prevented from being further damaged, wafer particles are prevented from polluting the fabricating equipment, and the operating efficiency and productivity of the fabricating equipment are enhanced.

Abstract: A skin resurfacing device for peeling the outermost layer of the skin for renewing the skin surface and repairing skin damage including a housing, a skin sensor, and a skin treater. The skin treater consists of an abrasive tip, a first end, a transparent portion, a first filter, and a second end, all of which are detachable and replaceable.
