Title: Optical fiber locator
Inventor: ISHIHATA YOSHINORI
IPC: G01M11/00
Filed: 1982-09-30
Abstract: PURPOSE:To confirm a fracture point regardless of the length of an optical fiber by increasing automatically the period of light pulses sent out to the optical fiber and detecting a shift in the peak position of Fresnel reflected light from the fracture point. CONSTITUTION:Output pulses of a clock part 1 are passed through a period selector 2 and light pulses from a laser diode 3 are sent out to the optical fiber 5 rhrough a coupler 4. Reflected light from an optical fiber cable 5 is converted photoelectrically by an avalanche photodiode 6. The mean value of measured values is calculated by an adder 9 and processed by a processing part 10 to be displayed on a display part 11. The length of the optical fiber is more than the limit length of the pulse period, so the reflected pulse appears in the area of the next period and the fracture point is easily recognized by mistake. When the period is increased several times, the reflection peak of the fracture piont appears at different places. When the length of the optical fiber is less than the limit length determined by the pulse period, the position of reflection is unchanged even when the period is increased. Thus, the period is increased automatically to measure the fracture point accurately without erroneous recognition.

IPC: H02P7/298
Filed: 1982-09-30
Abstract: PURPOSE:To prevent the saturation of the output when an antiparallel thyristor bridge circuit reversely converts by calculating the decrease amount of an AC power source by an armature voltage command. CONSTITUTION:A gate logic circuit 6 controls the firing of an antiparallel thyristor bridge 7 in response to the deviation i0 between the rotating speed command e0 and the speed signal e1 and the deviation between the deviation and the armature current i1. An armature voltage correcting circuit 30 outputs the difference Vc when the voltage V1 of the AC power source 1 is equal to or lower than the reference voltage V0. A subtractor 14 subtracts the armature voltage command E0 by the armature voltage E1 and the voltage control signal Vc and outputs the signal I1. A gate circuit 19 controls the firing of a thyristor bridge 20 in response to the signal produced by subtracting the field current command I0 by the signal I1 and the field current I2. In this manner, the output satiration of the converter when the antiparallel thyristor bridge circuit reversely converts can be prevented, thereby eliminating the overcurrent flowing through the motor 8.
