摘要： THIS DISCLOSURE RELATES TO A SELF-ALIGNING RACK. IN THE CUSTOMARY TRAVERSE MECHANISM COMPRISED OF A TRAVERSING MEMBER OR A RACK AND GEAR, IT IS IMPOSSIBLE TO OBTAIN AND MAINTAIN PERFECT ALIGNMENT BETWEEN ENGAGING TEETH. IT IS PROPOSED TO PROVIDE A RACK WHICH IS SELF-ALIGNING TO ABSORB THE STRAIN OF THE DRIVING FORCES WITHOUT INTERFERING WITH THE DESIRED TRUE TRACKING OF A SLIDABLE MEMBER OR CARRIAGE OF A MACHINE TOOL. A CROWNED SURFACE OF THE RACK IS SECURED AGAINST AN ADAPTER BY A PLURALITY OF SCREWS COMPRESSING A LIKE NUMBER OF COIL SPRINGS TO PROVIDE A RESILIENT MOUNTING FOR THE RACK AND THUS ALLOWING THE RACK TO TILT ON THE CROWNED SURFACE IN RESPONSE
TO ANY DEVIATION FROM THE FULL FACE TOOTH CONTACT FROM THE TEETH OF THE DRIVING GEAR TO PROVIDE REPETITIVE PARALLEL MOVEMENT OF A CARRIAGE IN MACHINED WAYS.-

摘要： A polishing apparatus and a polishing method capable of detecting whether a polishing tool has been brought into contact with a substrate, such as a wafer, and further capable of detecting a position of the polishing tool are disclosed. The polishing apparatus includes a substrate holder configured to hold a substrate, a pressing member configured to press a polishing tool against a surface of the substrate, an actuator configured to apply a pressing force to the pressing member, a motor-drive moving device configured to move the pressing member along the surface of the substrate, and a monitoring device configured to emit an alarm if a motor current supplied to the motor-drive moving device is smaller than a threshold value.
