摘要： PROBLEM TO BE SOLVED: To surely detect an impulse signal. SOLUTION: The impulse signal detector 10 is provided with a detector 13 that detects an input signal, a full wave rectifier 20 that converts the polarity of a detection signal received from the detector 13 into only the positive polarity, a low pass filter 14 that limits a frequency of a rectified signal to a prescribed band, a peak detector 21 that holds a peak of the signal that is band- limited, an A/D converter 15 that samples an analog signal from the peak level detector 21 synchronously with a time reference pulse and converts the sampled analog signal into a digital signal, and a signal processing circuit 16 that gives the sampling signal to the A/D converter 15 on the basis of a signal from a clock 18 and gives a reset signal synchronously with the sampling signal with a temporal deviation to the peak level detector 21, respectively.

摘要： PROBLEM TO BE SOLVED: To connect a current carrying live cable to the ground easily and safely. SOLUTION: At the first step, an outer covering layer 7 is stripped by a tool at a desired position between the end parts of a current carrying live cable 2 to expose a shield layer 6. At the second step, the conductor of a ground wire 8 is attached to the exposed shield layer 6, and wire 10 is wound around the shield layer 6 to connect the conductor of the ground wire 8 to the shield layer 6. After the connection, a conductive adhesive 20 is applied onto the shield layer 6 so as to cover the wire 10 and the conductor 9 of the ground wire 8 to bond the conductor 9 of the ground wire 8 to the shield layer 6. After the conductive adhesive 20 is applied at the third step, the portion bonded at the second step and its surroundings are covered with insulating tape 11 for completion of ground connection.

摘要： PROBLEM TO BE SOLVED: To provide a charge type cable way trouble survey device capable of identifying easily which direction a trouble point exists in, when positioned in the vicinity of a branch point in an electric wire.
SOLUTION: This charge type cable way trouble survey device is provided with magnetic sensors 3a, 3b for detecting bidirectional (X, Y) orthogonal magnetic fields, and an warning means for extracting and outputting a component of voice frequency band included in a time-differentiation of the magnetic field detected by each of the magnetic sensors 3a, 3b. The warning means outputs or displays separately the component of voice frequency band included in the time-differentiation of the X-directional magnetic field output from each magnetic sensor, and the component of voice frequency band included in the time-differentiation of the Y-directional magnetic field output therefrom, using two speakers 6 or level meters 8.

摘要： PROBLEM TO BE SOLVED: To easily manufacture various kinds of connecting edge protecting cover, capable of facilitating the carrying and maintenance thereof at low cost. SOLUTION: A connecting edge protecting cover 10 is provided with a protecting cover main body 11 and regulating members 12 to be fitted on corner parts of the protecting cover main body 11. The protecting cover main body 11 is formed by cutting a plate polypropylene into a rectangular shape, and formed of a ceiling part 13 and sidewall parts 15A, 15B connected to the ceiling part 13 through folding parts 14A, 14B. The sidewall parts 15A, 15B are formed with leg parts 17A-18B. A rubber 19 is adhered to the inside of the leg parts 17A-18B. When the sidewall parts 15A, 15B of the connecting edge protecting cover 10 are folded, the regulating members 12 are fitted in the corner parts formed by the ceiling part 13 and the sidewall parts 15A, 15B so as to hold the sidewall parts 15A, 15B at about 90 degree with respect to the ceiling part 13.
