摘要:
The present invention belongs to the technical field of alternating current induction servo motors, and particularly relates to a rotary-type induction servo motor with a constant-output-torque by using uniform magnetic fields and a linear-type induction servo motor with a constant-output-force by using uniform magnetic fields. The present invention has main features that the rotary-type induction servo motor or the linear-type induction servo motor is composed of N independent motor units; each independent motor unit has the same or similar structure, and is powered by single-phase alternating current; and the N independent motor units have an equal voltage magnitude of power supply, but voltage phases are different and form an arithmetic progression. In an independent motor unit of the rotary-type induction servo motor with a constant-output-torque by using uniform magnetic fields, the stator magnetic conductive silicon steel is simple in structure, and the winding manner of stator excitation windings is simple, similar to a multilayer solenoid type; rotor induction excitation windings are powered through induction, and no slip ring and related wearing parts are used. The rotary-type induction servo motor disclosed here can be operated at fixed voltage frequency, and in this case, the output torque and the voltage magnitude of power supply are in direct proportion, so the output torque can be controlled by adjusting the voltage magnitude. The motor does not adopt permanent magnetic materials, and has many merits including simple structure, good torque characteristic, simple controller design and high control precision. And meanwhile, based on the same principle, a linear-type induction servo motor with a constant-output-force by using uniform magnetic fields can be evolved from the rotary-type induction servo motor.

Methods for identifying an edge of a care area for an array area formed on a wafer and/or for binning defects detected in the array area are provided. One method for identifying an edge of a care area for an array area formed on a wafer includes determining a value for a difference image as a function of position from a position known to be inside the array area to a position known to be outside of the array area. The method also includes identifying the position that is located closest to the inside of the array area and that has the value greater than a threshold as a position of the edge of the care area.

A photovoltaic module mounting system having a rack structure, which includes a mounting rack structure having a rail (5) and two clamps (6) for holding a photovoltaic module (7) by a bolt (3) extending from a press plate (4) on an outer side of the module (7) to one of the clamps (6) mounted in an upper input space (51A) in the rail (5). Entrances (50A and 50B) are provided relatively for each of the two input spaces (51A and 51B) each providing a space to input one of the at least two clamps (6), which are mutual perpendicular. The longitudinal input space (51A) in the upper section of the substantially H shape rail is used to hold the clamp (6) to fix the photovoltaic module (7). The lateral input space (51B) is used to hold the clamp (6) to fix the rail (5) to the pre-location. It has an excellent function on lateral and longitudinal location. And the structure is simple, compact, efficient, adaptable and saves on material.

A method of transferring one or more substrates between process modules or load lock stations while minimizing heat loss is provided. In some embodiments the method comprising the steps of: identifying a destination location D1 for a substrate S1 present at an initial processing location P1; if the destination location D1 is occupied with a substrate S2, maintaining the substrate S1 at the initial processing location P1; and if the destination location D1 is available, transferring the substrate S1 to the destination location D1. In accordance with additional embodiments, the method is carried out on a system for processing substrates which includes two or more process modules, a substrate handling robot, a load lock chamber, and a transverse substrate handler. The transverse substrate handler includes mobile transverse chambers configured to convey substrates to process modules, wherein each mobile transverse chamber is configured to maintain a specified gas condition during the conveyance of the substrates. The transverse substrate handler further includes a rail for supporting the mobile transverse chambers, wherein the rail is positioned adjacent to entry of the process modules, and drive systems for moving the mobile transverse chambers on the rail.
