Abstract: PURPOSE:To obtain a coefficient of wavelength dispersion easily in a laid state by making modulated light incident to an optical fiber, obtaining calculated base band characteristics which are closest to the profile of actual base band characteristics measured at the output terminal, and calculating the coefficient which determines said characteristics. CONSTITUTION:A light signal modulated by a sine wave through an oscillator 21 and an electrooptic converter 22 is made incident to the optical fiber 14 to be measured and the signal appearing at the output terminal is passed through an optoelectric converter 23 to measure its level. The actual measurement data on a selected level meter 24 is plotted to obtain the actual base band characteristics. On the other hand, specific calculated base band characteristics having the profile closest to the actual base band characteristics are calculated by the computer simulation of a processor 25 from plural calculated base band characteristics which have the coefficient (m) of wavelength dispersion as a parameter, and the coefficient M of wavelength dispersion of the optical fiber to be measured is determined on the bases of the coefficient (m).

Filed: 1984-02-21
Abstract: PURPOSE:To shorten a processing time by detecting and tracking the parallel of the outline of a substance through an L filter and recognizing an object to be detected from the tracking length. CONSTITUTION:A filter position Pi at the detection of a filter feature point is moved to the intermediate point Ps between two outline candidate points Pa and Pb and the point Ps is stored as the tracking start position Ps of a subscanning direction. Then, the scanning position is moved to a point just above the starting position Ps by a distance, S, and when the point is the filter feature point, the scanning position is moved to the intermediate point of the outline candidate points, the scanning position is stored and whether a point just above the scanning position by the distance S is the filter feature point or not is checked. After ending the tracking, the tracking length (length of parallel line) is found out from the uppermost point PT and the lowermost point PS of the scanning positions sequentially stored during the tracking. When the tracking length is more than a certain reference, whether the tracking locus is arranged on a straight line or nor is discriminated.

Title: Monitor and fault searching system
Inventor: TOUGE TAKASHI
IPC: H04B17/40
Filed: 1981-03-05
Abstract: PURPOSE:To realize the discrimination of a fault between a transmission line and an intermediate repeater not only at each intermediate section but at an end office, by adding a function to discriminate the presence or absence of the input information to be given to the intermediate repeater. CONSTITUTION:The fault searching signal is reproduced from the signal of a transmission line through a discriminating and reproducing circuit 2, and furthermore the low frequency component that modulates the fault searching signal is extracted out of the said searching signal by an FF3 and a low pass filter 4. This low frequency component is transferred to an end office via a transformer 5, a band pass filter 6 and an intermediate pair 7. The frequency f0 with which the fault searching signal is modulated is previously decided for each intermediate repeater. The frequency f0 is varied to specify a fault area. In addition, the timing signal is extracted by a timing extracting circuit 9 and receives the peak wave detection through a signal break detecting circuit 10. Then an oscillator 11 works as long as no output of the circuit 10 exists, i.e., no input is applied to the intermediate repeater. Thus the low frequency signal is transferred to the end office.

Abstract: PURPOSE:To improve the followup ability of temperature correction of the title pressure sensor without providing any temperature sensor on the inside or outside of the sensor by converting two signals between two couples of opposite angle of a bridge resistor into digital signals after fetching and obtaining the real pressure by performing calculation on the digital signals. CONSTITUTION:When the title sensor E detects a pressure, the output signal VO of a bridge circuit A is converted into a digital signal by means of an A/D converter C after the signal VO is amplified at a differential amplifier B1 and, at the same time, signals VT at the feeding terminals Q1 and Q2 of the circuit A are also converted into digital signals after the signals VT are amplified at a differential amplifier circuit B2. A microcomputer M performs calculation on the two kinds of signals VO and VT and outputs a pressure value and temperature. While the signals V and V can be expressed by VO=f(P, t) and VT=g(P, t) and both of them rely upon the parameters of pressure P and temperature (t), the equations can be transformed into P=H(VO, VT) and t=J(VO, VT) and the real pressure P and temperature (t) can be found when the characterization technique is used.
