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 discharge impact breaking device capable of preventing generation of stray currents and ensuring operators' safety. SOLUTION: Cables 21, 22 for completely insulating from a casing 17 a charge-and-discharge circuit comprising a capacitor 5, a dc high voltage power supply 6 for charging the capacitor 5, a discharge switch 8 for discharging high-voltage energy stored on the capacitor 5, and the like which are provided inside the casing 17, and for supplying the high-voltage energy stored in the capacitor 5 to the electrodes 3 of a tubular container 2 from the casing 17, are each constructed of a single withstand voltage cable. This arrangement insulates the charge-and-discharge circuit completely from the casing 17 so that a current discharged into the ground from a metallic filament 4 flows only through the cables, thereby preventing generation of stray currents. By using withstand voltage cables as the cables 21, 22, they can withstand voltages during energy discharges to insure operators' safety.

摘要： PROBLEM TO BE SOLVED: To destruct an object surely in safety by exploding an explosive substance in a filling container using a triggering device, collapsing a liner disposed on the object side of the filling container with an explosive power thus generated to produce an ultrahigh speed destruction jet and bringing the destruction jet into collision against the object. SOLUTION: Triggering nitromethane is exploded by feeding a fine metal wire with electric energy thereby fusing and vaporizing the nitromethane. Explosion power of the triggering nitromethane is transmitted, as a bomb blast to a nitromethane 3 in a filling container 2 and the nitromethane 3 is exploded with the impact. According to the arrangement, a destruction unit 1 can be handled in safety and since an inexplosive nitromethane 3 is exploded surely using a trigger device 6 having safe and strong explosive power, an object 4 can be destructed surely or rendered fragile by forming a powerful destruction jet.

摘要： PROBLEM TO BE SOLVED: To improve the safety in handling a device by setting the impact force to be generated at the time of molten vaporization of a molten vaporizing material, a mean radius of a breakable container, thickness of the breakable container, and tensile strength of the breakable container so as to satisfy the predetermined relation. SOLUTION: Electric energy is supplied from a capacitor 14 to a metal narrow wire 2 so as to melt the metal narrow wire 2 for vaporization, and the breaking material 3 is exploded by the impact force at the time of molten vaporization so as to break a breakable container and so as to break a material 4 to be broken. In this case, the impact force F to be generated at the time of molten vaporization of the molten vaporizing material, a mean radius (r) of the breakable container, thickness (t) of the breakable container and tensile strength σ of the breakable container are set so as to satisfy the relation F.r/t>=σ. With this structure, the breakable container is broken by the only impact force to be generated with the expansion of the molten vaporizing material, and even in the case where the leak of the current is generated in a peripheral equipment, explosion is not generated as long as the electric energy enough for melting the molten vaporizing material for vaporization is not supplied. Safety at the time of handling the device is thereby improved.

摘要： PROBLEM TO BE SOLVED: To transmit the volumetric expansion force of a metallic small-gage wire efficiently at the time of discharge impact destruction. SOLUTION: In the discharge impact destruction device 1, a metallic small- gage wire 13 is melted and vaporized at a stretch and a destroy article 2 is broken by supplying the metallic small-gage wire 13 arranged into a vessel 11 with electric energy in a short time. The inside of the vessel 11 is filled with substances 14 for destruction and granular articles 15 at that time, and the volumetric expansion force of the metallic small-gage wire 13 can be transmitted efficiently because the granular articles 15 are also scattered together with the destroy substances 14 at the time of volume expansion by the melting and vaporization of the metallic small-gage wire. A metallic sphere, a pebble, a ceramic sphere, etc., are preferable as the granular article 15.
