Title: Method of controlling induction motor
Inventor: YOSHIDA TAKUMI
IPC: H02P23/14
Filed: 1984-11-30
Abstract: PURPOSE:To calculate an adequate torque current command and a slip frequency command at abrupt field magnetic flux varying time and to immediately follow up to a torque command by bringing a field command into coincidence with the actual field magnetic flux generated in a motor by the primary delay circuit CONSTITUTION:After an exciting current command i*d is suppressed to the maximum controllable value through a clamper 32, it is newly inputted as an exciting current command i**d to a coordinates converter 20. Further, a magnetic flux to be generated in the actual motor is predicted by the command i**d by the primary delay circuit 31, and the predicted field magnetic flux is used as the torque current command i*q of a torque control system and a field command phi** when calculating a slip frequency command omega*S. Accordingly, when the field magnetic flux abruptly varies,suitable torque current command i*q and slip frequency command omega*S can be calculated, and the motor torque tauimmediately follows up the set torque command tau*.

Title: Mechanism and method for wafer holding
Inventor: HORIOKA YUKICHI
IPC: H01L21/677
Filed: 1999-09-08
Abstract: PROBLEM TO BE SOLVED: To prevent generation of stains or scratches due to adhesion of stains or foreign matters of a wafer holding part by a method wherein there are provided a contamination preventing film which is pinched between the wafer holding part and a wafer and is capable of being conveyed when the wafer is not held; and a conveying mechanism part for conveying it. SOLUTION: A wafer holding mechanism 1 comprises: a holding part 3 for holding a wafer 2; a contamination preventing film 4 which is pinched between the wafer holding part 3 and the wafer 2, and is capable of being conveyed when the wafer is not held; and a conveying mechanism part for conveying it. When the wafer holding mechanism 1 is moved downward in a state that handler arms 11a, 11b are open and approach a predetermined position of the wafer, a contamination preventing film leads out a new part. Next, the handler arms 11a, 11b are closed, and wafer pressing members 3a, 3b pinch the wafer via a new part of the contamination prevention film. As a result, it is hard to generate adhering stains or foreign matters in the wafer holding part.
