摘要： A jaw for the chuck of a turning device such as a lathe generally comprises a base, a tooth adjustable relative to the base in the radial direction and a cam for adjusting the tooth position. The base may be held on the chuck and driven in a conventional manner. The tooth has a face for engaging a workpiece and is attached to the base such that the face is radially movable relative to the base. The cam includes a surface bearing against the base and a surface bearing against the tooth. The cam varies in thickness such that movement of the cam changes the radial distance between the base and the tooth. In exemplary embodiments, the cam is an eccentric cylinder that rotates to adjust the tooth or is wedge shaped and one or both of the bearing surfaces of the tooth and base are ramps.

摘要： A method and apparatus for increasing the electrical resistivity and corrosion resistance of the material forming a spacer layer in current-perpendicular-to-the-plane (CPP) giant magnetoresistive (GMR) sensors. The increased resistivity of the spacer layer, and thus, the CPP-GMR sensor permits a larger voltage across the sensor and a higher signal-to-noise ratio. The increased corrosion resistance of the spacer layer minimizes the effects of exposing the spacer layer to corrosive materials during fabrication. For example, adding tin to silver to form a metallic alloy spacer layer increases the corrosion resistance of the spacer layer and the electrical resisitivity of the CPP-GMR sensor relative to a spacer layer consisting solely of silver. The Ag—Sn alloy permits a larger current to flow through the sensor, which increases the signal-to-noise ratio.

摘要： A rotary drive for swinging a heavy member between two extreme positions. The drive transmits a rotary force provided by a motor or similar device through a first rotatable shaft to a second rotatable shaft perpendicular to the first shaft and connected to the heavy member. The second shaft rotates in an oscillatory manner between the extreme positions in response to rotation of the first shaft. The member may thus be positioned at any suitable location in its travel by operating the motor unidirectionally. The first shaft rotates about a first axis of rotation and rotates an arm about a second axis of rotation that intersects the first axis at an angle between zero and 90 degrees non-inclusive. The arm is connected to a universal joint having three mutually perpendicular axes. The universal joint transmits forces from the arm to the second shaft.
