Title: Method for diagnosing insulation deterioration of cable
Inventor: HORIKOSHI TOSHIO
IPC: G01R31/02
Filed: 1996-08-06
Abstract: PROBLEM TO BE SOLVED: To provide a water tree aging diagnosing method by which the insulation deterioration of a cable can be diagnosed highly reliably with high sensitivity by easily distinguishing similar signals caused by factors having no relation with deterioration. SOLUTION: In a method for diagnosing insulation deterioration of cable, the insulation deterioration of the insulator of a cable is diagnosed by measuring the residual charge of the insulator by applying an AC voltage across the insulator after the insulator is grounded after applying a DC voltage across the insulator.  At the time of diagnosis, such operation that the AC voltage is immediately dropped to zero after the voltage is boosted to a prescribed value from zero in a short time and the increased amounts ΔQ (ΔQ1 , ΔQ2 , and ΔQ3 ) of residual charges due to the short-time application of the AC voltage is repeated two times and the charge difference Q0 (=ΔQ1 -ΔQ2 ) obtained by subtracting the ΔQ2 from ΔQ1 is used for discriminating the deterioration, where ΔQ1 and ΔQ2 respectively representing the increased amounts of the charges by the first and second applied AC voltages.

Title: Method of erasing recording
Inventor: TSUTSUI KYOJI
IPC: B41M5/26
Filed: 1990-08-06
Abstract: PURPOSE:To ensure cancel of recording due to variation of a crystal state or variation of a phase of a recording layer by a method wherein irradiation conditions of light beams in recording and in erasing are suitably selected. CONSTITUTION:In recording the temperature of a recording layer must be a melting point or an isotropic point or higher. Even steep temperature distribution in a thickness direction of the recording layer may be tolerable. However, since a laser beam is applied to heat the recording layer in a considering narrow range of temperature uniformly in erasing a gentle temperature distribution should be formed. Therefore, abovementioned temperature distribution is formed as follows by paying attention to the fact that the less the temperature difference between an erasing light irradiation part and its surrounding part is, the more gentle the temperature distribution to be produced in irradiation becomes. That is, a part including a recording part to be erased is heated to a temperature lower than the temperature at which the recording is erased. After keeping the part at the temperature it is heated to a temperature within the erasing temperature range. Thereby, the gentle temperature distribution as abovementioned is formed.

Title: Control method of adaptive array and adaptive array device
Inventor: HOJUYAMA OSAMU
IPC: G10L21/0208
Filed: 1997-08-01
Abstract: PROBLEM TO BE SOLVED: To reduce the noise caused by breathing and to speedingly follow up the movement of an interference signal source while maintaining the quality of the output signals high. SOLUTION: In a beam former 2, the sensitivity against an object signal source is made higher than the sensitivity against other signal sources. In a beam former 3, the sensitivity against the object signal source is made lower than the sensitivity against other signal sources. Then, the step size of an adaptive algorithm in adaptive filters 70 to 7M-1 is determined using the indexes related to the output signal amplitudes of the beam formers 2 and 3. Thus, the degradation of the signals in a final output and the noise caused by breathing are reduced even though the constant, which determines the step size, is set larger in order to increase the follow up speed against the movement of an interference signal source.
