Title: Superconductive magnetic bearing
Inventor: TAKAHATA RYOICHI
IPC: F16C17/08
Filed: 1989-05-19
Abstract: PURPOSE:To simplify the supporting structure by forming one of a superconductive material and a permanent magnet in such a manner as to have a cylindrical portion set in the inside diameter larger than that of the end portion of the other thereof and orienting the magnetizing direction of the permanent magnet parallel to the axial direction of a rotary shaft in a thrust supporting bearing. CONSTITUTION:Spherical permanent magnets 2, 3 having the same diameter as that of a rotary shaft 1 are fitted to the upper and lower ends of the rotary shaft 1, and the magnetizing direction thereof is made parallel to the axial direction of the rotary shaft 1. Cylindrical superconductive materials 4, 5 are disposed in positions opposite to the permanent magnets 2, 3, and the inside diameters thereof are made larger than those of the permanent magnets 2, 3. The permanent magnets 2, 3 are repulsed in the axial direction of the rotary shaft 1 by the Meissner effect of the superconductive materials 4, 5 to support the thrust load of the rotary shaft 1. As the open side cylindrical portions of the superconductive materials 4, 5 surround the end portions of the permanent magnets 2, 3, the repulsive forces of both materials work towards the centers of the permanent magnets 2, 3 so that the shaft centers of the permanent magnets 2, 3 and the rotary shaft 1 are maintained in alignment with the shaft center of the superconductive materials 4, 5. Thus, the rotary shaft can be supported stably in a simple constitution.

Abstract: PURPOSE:To make possible correct exposure for the main subject even for the subjects having the special luminance distribution by performing weighting to the maximum or minimum luminance of each zone of a photometric region and performing exposure controlling by the use of the added luminance. CONSTITUTION:A photometric part 5 having photometric elements 2a-2n on a substrate 1 are constituted by the photometric parts 5a-5d corresponding to the segmented zones Z1-Z4 or Z1'-Z4', and the outputs of the respective photometric elements are logarithmically converted 30, and are then supplied to maximum luminance detecting circuits 31a-31d, by which the maximum luminance Bzi is detected zone by zone. From the output signals of all the photometric elements, the mean luminance of the entire image plane is calculated 32. The subject luminance is calculated 33 by using this mean luminance and zone-by-zone maximum luminances Bzi, and this luminance information is operated 34 by the information from an exposure information setting circuit 35 of film sensitivity, aperture and shutter speed, whereby an exposure control circuit 36 is driven. In this case, the controlling of exposure is accomplished by using the luminances of the formulas I, II weighted and added according to the importance of each zone.
