Temperature compensation is achieved by adjusting a divide ratio of a multi-modulus divider circuit in a feedback path of a phase-locked loop based on the detected temperature. Proximity zones are established along the edge of the active area. The slot management module converts the virtual slot identification information into physical slot identification information while referring to the physical slot to management slot contrast table, and accesses the slot control module corresponding to the physical slot identification information, thereby realizing a physical access of the input and output control module to the slot interface. A difference between a rotational speed at a front of the paste chamber and rear of the chamber causes the flexible chamber to contract on itself thereby automatically forcing polish from the chamber and into a polish applicator.
