Title: Method and instrument for measuring curvature distribution of optical fiber
Inventor: TATSUTA MITSUHIRO
IPC: G01M11/00
Filed: 1989-06-29
Abstract: PURPOSE:To measure the influence itself of the bend of an optical fiber without requiring reference data (initial data) by measuring a Brillouin gain spectrum and finding out the ratio of a gain peak related by a reference acoustic waveguide mode to a gain peak related by a high-order waveguide mode. CONSTITUTION:A pulse-like signal beam S1 emitted from a light source 1 is connected to one end of an optical fiber 3 to be measured through a multiplexer/ demultiplexer 4 and a beam S2 emitted from a light source 2 is connected to the other end of the optical fiber 3. A difference between optical frequency values of the two light sources 1, 2 is controlled by an optical frequency control device 7 to excite plural acoustic waveguide modes having different degrees. Since the generation efficiency or attenuation rate of the high-order acoustic waveguide mode strongly depends upon the curvature of the optical fiber 3, the ratio of Brillouin gain of the high-order acoustic waveguide mode on the specific position of the optical fiber to that of the reference acoustic waveguide mode is found out by a signal processor 6 and the curvature distribution of the optical fiber 3 is measured, so that reference data are not required.

IPC: H02K19/10
Filed: 1989-06-29
Abstract: PURPOSE:To maximize torque generating section by setting the tooth width of rotor and that of stator salient pole to a value obtained by dividing the circumference of a circle having a radius equal to the distance between the center of rotation of the rotor and the tooth face of the rotor salient pole by a value two times of the tooth number of the rotor salient pole. CONSTITUTION:The circumference of a circle having radius equal to the distance between the center of rotation of a rotor 1 and the tooth faces 1a-1d of rotor salient pole is divided by a value two times of the number of tooth of the rotor salient pole. Thus obtained value is employed as the tooth width of rotor and stator salient poles. Consequently, the distances between the tooth widths of the rotor salient pole and respective rotor salient pole teeth are identical. When exciting current is fed to the exciting windings of rotor salient pole teeth A, A', C, C', the rotor 1 rotates counter clockwise. During rotation, the area of the salient pole teeth A, A' of the stator 2 facing with the salient pole teeth 1a, 1c of the rotor 1 and the area of the salient pole teeth C, C' of the stator 2 facing with the salient pole teeth 1b, 1c of the rotor 1 increase and vary continuously thus producing torque continuously.
