Title: Power generator and fully automatic washing machine
Inventor: ASADA KAZUHIKO
IPC: H02P25/03
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To facilitate control by passing exciting current through the winding of the second object which serves as a rotor, without passing through a slip ring and a brush. SOLUTION: Second winding 22a-22b are wound around an iron core 21 of a second object 2, and a rectifier 23 is inserted and connected to the iron core 21. Quadrature-axis current of normal drive current is flowed into a three- phase winding 7 from an inverter 5 during the duration of continuity at an electrical angle of 120 deg., and a direct-axis current which is interrupted at high frequencies within respective electrical angles of 60 deg. based on the signal of a high frequency oscillator 24, is flowed into the three-phase winding 7. Induced electromotive force at high frequencies is generated at second winding 22a-22b by an electromagnetic coupling with the three-phase winding 7, and DC exciting current rectified by rectifiers 2-3 flows. Mechanical force is generated for rotation by a magnetic field and the quadrature-axis current is generated as a result.  The exciting current of the second winding 22a-22b can be regulated by the direct-axis current so that it is thus possible to conduct speed control over a wide-range as in a dc machine.

Title: Maintenance method for optical cable
Inventor: UESUGI SUNAO
IPC: G01M3/04
Filed: 1983-03-30
Abstract: PURPOSE:To eliminate the need for a gaseous pressure detector, etc. and to enable constitution of a high density optical cable by utilizing the optical fiber itself as a detector for the damage in the sheath of the optical cable and detecting the position and degree of damage by means of a light pulse tester. CONSTITUTION:An optical fiber 3 for detecting moisture is provided in an optical cable, and the change in the loss value of the fiber 3 is measured with a light pulse tester 8. When the sheath is damaged at a damage point 7 and moisture intrudes therein, the loss value of the fiber 3 increases near the damage point. The line loss of the fiber 3 from the terminal of an optical transmission line is measured with the tester 8, by which the increase in the loss value is known. Since the tester 8 measures said loss by a loss measuring method using a backward Rayleigh scattering light, an intervening pair is not necessary. The position and the increase in the loss of the point 7 are measurable. The need for a gaseous pressure detector, etc. is thus eliminated and since the consideration for the flowing resistance of gas is not necessary, the high density optical cable is constituted.
