Title: Rotor for squirrel-cage induction motor
Inventor: ISHIKURA SATORU
IPC: H02K17/16
Filed: 1978-08-11
Abstract: PURPOSE: To reduce the higher harmonic asynchronous torque of a squirrel-cage induction motor and prevent crawling, by providing slits between rotor core slots containing secondary conductors so that the electric resistance between the secondary conductors is increased.  
     CONSTITUTION: The rotor of the squirrel-cage induction motor is made of the secondary conductors 3 housed in the slots provided in numerous stratified iron sheets. The slits 6 are opened between the secondary conductors 3 so that the electric resistance between the conductors is increased. Thus, the higher harmonic asynchronous torque is reduced and the decrease in the minimum acceleration torque due to the difference in the electric resistance between the secondary conductors 3 of the rotor is prevented. This results in preventing crawling. The slits 6 can be applied to a skewed motor as well.

Abstract: PROBLEM TO BE SOLVED: To attain exposure by matching the surface of a substrate to be exposed with the image face of a projection optical system with high precision even when the running face of the substrate is not parallel to the image face of the projecting optical system. SOLUTION: The focus position of the surface of a wafer W is detected at a detection point in an illumination field 3 and a detection point in a first reading area at the front side in a scanning direction to the illumination field 3 by multipoint AF sensors 19A and 19B.
