Abstract: A thermal displacement compensating device calculates a thermal displacement amount which is produced by heat generation or dissipation as a machine tool is actuated or stopped and changes with time. A thermal displacement compensation amount is calculated by multiplying the calculated thermal displacement amount by a coefficient. A position command is compensated by adding the thermal displacement compensation amount to the position command. On the other hand, a variation between a thermal displacement amount calculated last time and a current thermal displacement amount is determined for each predetermined time. A plurality of thermal displacement amount change states are identified based on comparison between the determined variation and a predetermined threshold. The coefficient is calculated based on the identified thermal displacement amount change state.
Abstract: A smart circuit breaker for an AC power supply circuit that has a limited capacity for supplying power to one or more electrical loads. Smart circuit breaker includes a sensing circuit to dynamically determine the available load capacity of the AC power supply circuit. A reporting circuit reports the dynamically available load capacity to a controller, an existing electrical load, and/or a potential electrical load on the AC power supply circuit. The AC power supply circuit, the existing electrical load, and/or the potential electrical load can adjust operations based on the reported availability of load capacity.

Abstract: This specification discloses an intelligent and digitalized process level interface which is referred to herein as an Intelligent Process Interface (IPI). The input of the IPI includes both analog and digital channels and therefore the IPI can be used for substations in transition or retrofit stages with both conventional and non-conventional primary devices. The IPI acts not only as a digitalized interface, but also as an intelligent supervisory and control unit for switching functions. The architecture of the IPI is flexible and allows for the functionality to be distributed to several devices.

Abstract: A coating and developing treatment apparatus includes a substrate transfer mechanism; and a defect inspection section. A transfer control part controls transfer of a substrate. A defect classification part classifies a defect based on the state of the defect. A storage part stores a transfer route of the substrate by the substrate transfer mechanism when the substrate has been treated by treatment sections. A defective treatment specification part specifies, based on a kind of the defect classified by the defect classification part and the transfer route of the substrate stored in the storage part, a treatment section which is a cause of occurrence of the classified defect, and judges presence or absence of an abnormality of the specified treatment section. The transfer control part controls the substrate transfer mechanism to transfer a substrate bypassing the treatment section which has been judged to be abnormal by the defective treatment specification part.

Abstract: A system and method for real-time feeder reconfiguration are disclosed for load balancing in distribution system automation. The load balancing of transformers and feeders can be achieved by load transfer from an overloaded transformer or feeder to an adjacent transformer or feeder which is lightly loaded. An exemplary method can include defining an objective function as a sum of squares of the load deviation of transformers/feeders. The minimization of this objective function determines the optimal operating states (open or closed) of sectionalizing switches. The load balancing operation of transformer and feeder can be carried out by a single operation in which a plurality of switches is reconfigured.
