Abstract: A coordinate system correcting apparatus corrects a reference coordinate system set for a work space of a machine tool (3). A plurality of jig members (18) are distributedly arranged on a work table (12) of the machine tool (3), each of the jig members (18) has a plurality of right-angled parallelepipedic recesses (18a,b,c) and an intersection of three orthogonal planes of each of the recesses (18a,b,c) forms a space lattice point. The space lattice points defined by the jig members (18) coincide with predetermined normal space lattice points if the machine tool (3) is not distorted, and if the machine tool is distorted, deviate from the normal space lattice points. Eight adjacent space lattice points are located at vertexes of a hexahedron, respectively. When the machine tool (3) is distorted, the jig members (18) define distorted space lattice points, which are measured with a probe unit (17). According t to the normal space lattice points and distorted space lattice points, the reference coordinate system is three-dimensionally corrected for each of the hexahedrons.

Abstract: The present invention relates to a method and apparatus for remotely detecting impedance. It is specifically adapted for use on a polishing machine wherein the end point of polishing for removing a surface layer during the processing of semiconductor substrates is detected. A first, or stationary coil (48) having a high permeability core is wound having an air gap and an AC voltage is applied to the stationary coil (48) to provide a magnetic flux in the air gap (66,68,70,72). A second coil (46) is mounted for rotation on the polishing table (26), in a position to periodically pass through the air gap of the stationary coil as the table rotates. The second coil is connected at its opposite ends to contacts (42) which are embedded in the surface of the polishing wheel. The contacts are positioned to engage the surface of the substrate which is being polished and provide a load on the second or rotating coil. The rotating coil, when it is in the air gap (66,68,70,72) of the stationary coil, will perturb the flux field therein as a function of the resistance of the load caused by the contacts (42) contacting either a conducting surface or a non-conducting surface. This perturbance of the flux field is measured as a change in the induced voltage in the stationary coil which in turn is converted to a signal which is processed to indicate the end point of polishing, the end point being when a metallic layer has been removed to expose a dielectric layer therebeneath or, conversely, when a dielectric layer has been removed to expose a metallic layer therebeneath.

Abstract: A fastener driving tool having a power mechanism operable during a fastener driving stroke to drive a fastener into a workpiece when an operator depresses a manually operable trigger and a safety member is in an actuated position. A safety mechanism for the fastener driving tool includes an interlock mechanism associated with the trigger and the safety member that assures that (1) the trigger will not be depressed from its standby position to its actuated position unless the safety member is moved to its actuated position; (2) the safety member will be locked into its standby position if the trigger is depressed prior to the safety member being depressed against the workpiece; (3) the trigger will be permitted to return toward its standby position even though the safety member is not fully engaged against the workpiece so that the fastener driving tool is reset to a static condition; (4) the trigger is permitted to return to its rest position only when the safety member is in its actuating position; and (5) the safety member will be prevented from returning from its actuated position to its standby position while the trigger is still in its firing position. In order to accomplish these safety interlock functions, the trigger has a trigger rod and the safety member has a series of reliefs into which the trigger rod may become lodged depending on the relative positions of the trigger and the safety member.

Abstract: The invention relates to a process for controlling a small hydroelectric plant which has a turbine, a generator, a resistor and a control for distributing the current generated by the turbine to a user, and has the resistor for keeping the total current drawn constant, the control undertaking a corresponding variation of the output, converted into heat in the resistor, in the event of any variation of the power drawn by the user, but simultaneously or immediately thereafter varying the output of the turbine, for example by varying the admission, so that the output converted into heat in the resistor resumes the original value. According to the invention it is proposed that the turbine output be varied as a function of the magnitude of the electrical output converted into heat in the resistor and that a differential circuit determine whether the magnitude of this output:     lies above a predetermined upper value (upper switch point), lies between this upper value and a predetermined lower value (lower switch point), or   lies below this lower value;  where, as a function of this comparison:     in the first case the output of the turbine is restricted,   in the second case the output of the turbine is not varied, and   in the third case the output of the turbine is increased, the lower switch point preferably lying just above the power drain of the largest single consuming unit of the mains system supplied by the small hydroelectric plant. The invention also relates to a control element for varying the turbine output, preferably used for this process. <IMAGE>
