摘要： PROBLEM TO BE SOLVED: To perform a precise geophysical exploration by analyzing a received elastic wave by use of the time of the discharge current peak value when the discharge switch of a focus device is ON to supply electric energy to a conductive material as impact force developing time. SOLUTION: This device is formed of an impact developing device 10, an acceleration sensor 4 and a vibration measuring device. The impact developing device 10 is provided with a focal vibration device 1 mounted on a natural ground 2 and an electric energy supplying device for supplying electric energy thereto. The focal vibration device 1 internally has a metal thin wire 1a and a transmitting material for transmitting the impact force by the evaporation thereof. When a discharge switch 8 connected to a discharge electrode 5 within the supplying device 3 is ON by the signal of a trigger circuit 9, the metal thin wire 1a is fused by the electric energy of a capacitor 7 to develop a discharge impact force. The vibration measuring device 11 takes the peak value generation time by the detection signal of discharge current as the impact force developing time of the focal vibration device 1 and analyses the vibration acceleration measuring time or attenuation from the acceleration sensor 4 on the basis of it, whereby the exploration position can be made clear.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device capable of accurately sorting even if mixed particles have small particle diameters. SOLUTION: A mixture of particles, which is supplied to a separation space 9, is electrostatically charged, by impressing a high-voltage to a vibrating electrode plate 3a, made inclined at a predetermined angle, and to a needle-shaped electrode 31b placed over the electrode plate 3a through a separation space 6 to discharge ion, and is attracted to the vibrating electrode plate 3a. Then, particles of a conducting material are neutralized by coming into contact with the electrode plate 3a and then are electrostatically charged in homopolarity with the electrode plate 3a. Accordingly, when the electrode plate 3a is vibrated, the particles of the conducting material repelling the electrode plate 3a are hardly influenced by carrying force of vibration and slip down in the dipping direction by gravitaty. Plastic particles attracted and biased to the electrode plate 3a are carried in the carrying direction by the vibration of the electrode plate 3a. Thereby, the plastic particles and the particles of the electric conductor are carried in the different directions and separated.

摘要： PROBLEM TO BE SOLVED: To sort/separate a metallic piece and plastic pieces according to their kinds at one sorting stage. SOLUTION: Respective electric charges are imparted to respective components of a mixture before supply by triboelectrification. The mixture is irradiated with a negative ion from an ion discharging electrode 5 so that the electrified amount of the negatively charged plastic piece is increased and the piece is adsorbed on a rotating drum electrode 4 and the electrified amount of the positively charged plastic piece is decreased to repel the electrode 4. Metallic fine powder is brought into contact with the electrode 4 so that the metallic fine powder is electrified to have positive polarity and repel the electrode 4. In an electrostatic field S for separation, the plastic pieces are separated by their kinds by making the plastic piece having an almost neutral charge amount draw an intermediately falling locus and making the plastic piece having a negative charge draw an internally falling locus while being attracted to the electrode 4 by the electrostatic force. The metallic fine powder is separated by making it draw an externally falling locus while being attracted to an electrostatic electrode 6 side by the electrostatic force.
