IPC: H02K1/18
Filed: 1989-08-28
Abstract: PURPOSE:To eliminate vibration and noise by a method wherein a fitting recess is formed such that the angle between the bottom face and the side face thereof is equal to or larger than the angle at which the extension of the side face passes through the center of the core, thermally expanding the outer ring core and inserting a magnetic pole core therein, and then coupling the magnetic pole core and the outer ring core through contraction of the outer ring core. CONSTITUTION:An outer ring core 5 having such dovetail fitting recess 15 as the angle between the bottom face 15a and the side face 15b thereof is equal to or larger than the angle at which the extension of the side face 15b passes through the center P of the core 5 is thermally expanded, and then a magnetic pole core 3 is inserted into the outer ring core 5. When the outer ring core 5 is cooled, the outer ring core 5 contracts toward the center P thereof and coupled mechanically with the magnetic pole core 3.

IPC: G01B11/00
Filed: 1993-09-06
Abstract: PURPOSE:To obtain highly accurate measurements by providing a system of two lenses that forms images of a subject for distance measurement and those of a reference object, photosensors, a reference-position detecting means, and a means for correcting the measured distance in accordance with the amount of deviation. CONSTITUTION:A beam of light made incident from a subject for distance measurement passes through the image receiving areas 4B, 4R for the subject for distance measurement, each of which has a certain viewing angle, and the beam then passes basic and reference lenses 2B, 2R and forms images on basic and reference 3B, 3R. The light beam, used in image formation on the lens 3B and passed through the lens 2R, forms an image on the sensor 3R. The images formed on the sensors 3 of the subject for distance measurement are converted from analog to digital form and outputted in time series. A phase difference is detected through a correlating operation on the position of image formation on the sensor 3B and the position of image formation on the sensor 3R. The positions in which a reference light source forms images on the sensors 3B, 3R are determined so as to detect the deviation of the optical axis. The phase difference between the images of the subject for distance measurement, which is obtained through the correlating operation, is corrected based on the deviation of the optical axis, and arithmetic operations for distance measurement are carried out.
