Filed: 1989-04-28
Abstract: PURPOSE:To prevent the abrupt increase of the magnetic flux density of an auxiliary pole while reducing the number of parts by charging the radial thickness of the auxilia ry pole according to the position on the magnetizing field side and by changing an air gap from the outside diameter of an armature according to the position on the magnetizing field side. CONSTITUTION:A main magnetic pole 3 is arranged from the central axis of the magnetic pole toward the demagnetizing side end of an armature-reaction flux. Also, an auxiliary pole 4 is arranged on the magnetizing field side on which the armature- reaction flux acts. Further, an armature 5 is rotatably mounted in the inner peripheral space of a field opening pole 1 and is arranged with an air gap (g) from the inner periphery of the field opening pole. In this case, the radial thickness of the auxiliary pole 4 is changed according to the position of the magnetizing field of an armature reaction so that the air gap between the auxiliary pole 4 and armature 5 is constituted in the manner of air gap g1 < air gap g2 as the air gap approaches the magnetizing side end. Thus, when a shown field distribution 6 caused by the armature reaction changes gently without increasing or decreasing abruptly, it is possible to improve the prevention of magnetic noise and demagnetizing characteristics applied to a main pole demagnetizing field end.

Abstract: PURPOSE: To compute the ground migration length of a flight vehicle, a ground speed and a three-dimensional position with high accuracy and in real time by transforming two images picked up at interval of time into one to have a fixed scale with respect to an actual object and computing a dislocation quantity between both images. CONSTITUTION: Two images picked up at a predetermined passage time by a CCD camera 3 fixed by a gyrostabilizer in a horizontal and a vertical directions are transformed into one to have a certain unified scale on the basis of a distance measured by a range finder 6 and are respectively stored into memories 8, 9. Both images are correlated with each other by correlation computing means 11, and the three-dimensional position and the ground migration length of a flight vehicle are computed from the dislocation quantity of both images and the transformed scale factors by a speed computing means 12 and at the same time the ground speed of the flight vehicle is computed from the ground migration length and the image pick-up interval.  Since the scale and the azimuth of both images are unified, even when the change of an altitude, the tilting of an airframe and the change of a road are brought about, high-speed correlation and quick measurement can be made because it is unnecessary to displace, reduce and magnify the images at the time of correlation.
