IPC: G01S7/62
Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To improve the target detection rate and reduce false alarm by extracting and integrating plural characteristic elements of a target signal to calculate the certainty of a target signal. SOLUTION: A signal processing part 2 receives a signal from a target and outputs the azimuthes of plural time series signals and received signals extracted remarking plural elements of the signal. A signal detecting part 3 extracts a signal zone seemed to be a target according to the level and duration of each of plural time series signals, takes signals of the signal zone as a target signal, and calculates the target information, the target azimuth and distance of the target signal in the signal zone. Subsequently, a target detecting part 4 calculates the position of a target by integrating target signals extracted on each of plural time series signal.  A target sorting part 5 performs weighting for the calculated target information, calculates the certainty showing the degree of target likeliness of the target signal integrated according to the weighted target information, and displays the same.

Title: Interference wave extracting circuit
Inventor: URATA KATSUYA
IPC: H04L27/00
Filed: 1986-12-19
Abstract: PURPOSE:To absorb the frequency fluctuation of an interference wave and to improve the C/N of an extraction signal by controlling so as to make the frequency of a signal obtained by transforming in frequency the interference wave coincide with the pass band of a narrow band pass filter and removing a frequency component except the interference wave. CONSTITUTION:A first mixer 11 uses the signal of a voltage control oscillator 12 to transform an input signal in the frequency and the narrow band pass filter 13 takes out the interference wave component from the output of the mixer 11. A detection circuit 16 detects the level of the output of the narrow band pass filter 13 and the voltage control oscillator 12 generates the signal of the frequency changing so as to make the output level of the detection circuit 16 maximum. A second mixer 18 uses the signal of the voltage control oscillator 12 to reversely transforming the output of the narrow band pass filter 13 in the frequency to the first mixer 11 and generate an interference wave output. Thereby, when there is the frequency fluctuation in the interference wave, the frequency component except the interference wave is completely suppressed to improve the C/N of the extraction signal.

Abstract: PURPOSE:To seal insulating gas and to eliminate the influx of mold resin into the insulating margin section of dielectric layer in order to prevent the lowering of corona starting voltage, by employing a series of processes in which space is formed in both the end sections of a capacitor element disposed in a vessel of synthetic resin which is in semi-curing state, and a vessel of synthetic resin is then filled with insulating gas, and curing is thereafter performed. CONSTITUTION:A lead 4a is passed through a through hole 5a bored through a vessel main body 3a to place a capacitor element 4 therein, and a lead 4b is then passed through a through hole 5b bored through a cap body 3b to receive the capacitor element 4. Next, the obtained structure is placed in a vacuum vessel and the vacuum vessel is then evacuated of air at pressures of 10<-4>mmHg. Under this condition, when insulating gas 7 is introduced into the vacuum vessel, the insulating gas 7 is passed through gaps 6a, 6b to fill in the vessel main body 3a. Subsequently, both the vessel main body 3a and the cap body 3b are heated with being pressurized so that the epoxy resins thereof, which are in semi-curing state, are united each other by curing reaction. As a result, the insulating gas 7 can be sealed in a vessel 3. In the capacitor 8 produced in such a way, mold resin does not flow in the gap of insulating margin section of dielectric layer, and the variations in corona starting voltage can be reduced.
