Title: Bearing bracket
Inventor: TANAKA AKIRA
IPC: F16C35/02
Filed: 1983-05-30
Abstract: PURPOSE:To improve the anti-fatigue strength by forming a plurality of cut parts directed towards a disc side from the starting-up edge in the vicinity of the welded part between a circumferential rib and a radial rib, in a bearing bracket having disc for thrust bearing which is ued in vertical-shaft rotary electrical machinery. CONSTITUTION:A plurality of cut parts 12 are formed towards a disc 1 from the starting-up top edge of a circumferential rib 9, in the vicinity of the welded part 13 between the circumferential rib 9 and a radial rib 6. when the depth (t) of cut increases over a limit with respect to a pitch 2P, the part where the stress becomes zero appears between the cut parts 12. Therefore, the max. tensile stress in the direction of height of the circumferential rib 9 can be reduced. Therefore, the number of repetition up to destruction can be increased markedly, and the anti-fatigue strength can be improved.

Title: Helical loop antenna
Inventor: ITO SADAO
IPC: H01Q7/00
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To provide a compact and light-weight helical loop antenna at low cost while maintaining its characteristic by winding a metallic wire in a helical loop shape where the curvature radius of the wire is kept small compared with the using wavelength. SOLUTION: A metallic wire is helically wound with its curvature radius kept small compared with the using wavelength and formed in a loop shape with the total helical length set at about one-to-several value of the using wavelength. Then both ends of the wire are connected to a feeder line 2. In such a constitution, a helical loop antenna is obtained. The characteristic impedance of this loop antenna can be changed when the loop shape is changed, and the matching is facilitated between an antenna element 1 and the line 2 connected to the element 1. Furthermore, the antenna characteristic can be changed when the section size of the metallic wire, the helical curvature radius, the number of turns set per unit length, etc., are changed. Thus the antenna design is facilitated.
