Filed: 1991-05-07
Abstract: PURPOSE:To compensate a dropout with a high quality by writing the converted value of a reproduced video signal from an A/D converting means, and a specific value for indicating a dropout detection in a memory means so as to coexist. CONSTITUTION:When the value successively converted by an A/D converter 2 is turned to a specific value Xn, a level converter 13 converts it into an another value which has no influence on a visual sensation.

Thus, the specific value Xn is made to coexist after the A/D conversion, so that the accuracy of 1LSB can be ensured. The data replaced by the means 14 are successively written in a time axis correcting line memory 3 by a clock generated from a writing clock generator 6, the written data are successively read out by a reading clock, and the fluctuation of a time axis can be corrected.

Title: Insulation deterioration monitoring method for power cable
Inventor: MATSUKI MASAKI
IPC: G01R31/12
Filed: 1993-04-28
Abstract: PURPOSE:To provide a method for monitoring insulation deterioration of a power cable which can identify an external sudden noise and a partial discharge detection signal and accurately specify the charge amount of the detected signal. CONSTITUTION:A partial discharge pulse is detected by a foil electrode 3 and a detecting impedance 4 mounted at an insulation intermediate connector 2 of a power cable 1, and transmitted to a spectral analyzer 10 through an optical fiber 7. The analyzer 10 frequency-analyzes a measured signal regarding a frequency band of 1MHz or more, and applies it to an arithmetic processor 11. The processor 11 integrates a ratio of a partial discharge measured value to a previously measured noise signal or difference therebetween in terms of a frequency with respect to a specific frequency band relatively not affected by influence of noise, and decides presence/absence of the partial discharge according to this value. A calibration pulse is injected by a calibration pulse generator 14 thereby to estimate a partial discharge amount.
