摘要： PROBLEM TO BE SOLVED: To extend a prospecting range, and to propagate an elastic wave with proper amplitude to prospecting a natural ground. SOLUTION: A seismic center device for geology prospect measures the reflection wave or the refraction wave due to the prospecting ground of an elastic wave which is generated from a seismic center device 4 for prospecting the geology of a natural ground. The device is provided with a metal small-gauge wire 8 that is arranged in an earthquake-generating container 6 and is quickly dissolved and vaporized by electric energy being quickly supplied, an explosive substance 9 that is filled into the earthquake-generating container 6 and is exploded by dissolving and vaporizing the metal small-gauge wire 8, and a supply device for supplying the electric energy to the metal small-gauge wire 8. When the amplitude of the elastic wave in the prospecting natural ground is set to A, distance from a seismic center position to the prospecting natural ground is set to L, a coefficient regarding the amplitude A of the elastic wave and the distance L is set to α, a coefficient regarding the distance of the elastic wave is set to n, and a coefficient regarding the capacity and amplitude of the explosive substance is set to m, the capacity QA of the explosive substance is represented by as QA=[(A×L )/α] . In this case, the coefficient α should be set to 770

摘要： PROBLEM TO BE SOLVED: To obtain an optimum mixing state of fly ash and to improve a fly ash processing capacity by a method in which when fly ash is heated in a reactor while being agitated by a paddle agitator to decompose dioxin in the fly ash, the width of paddles is specified with regard to the inside radius of the reactor. SOLUTION: This fly ash dioxin pyrolyzing apparatus 1 is provided with a reactor with a cooling water jacket 3 and a paddle agitator 4 for agitating fly ash in the reactor 2. Fly ash introduced into the reactor 2 from one end side of the reactor 2 is heated in the reactor 2 while being agitated by the agitator 4, dioxin is decomposed, and decomposition gas is discharged from the other end side. On this occasion, the width of paddles 4a is set up to be 0.25-0.4 time the inside radius of the reactor 2. The relationship among the radius R (m) of the reactor 2, the number of rotations N (rpm) of the paddles, and the acceleration of gravity G (m/s ) meet the relationship 220 /G

摘要： PROBLEM TO BE SOLVED: To prevent breakage of a rotary cutter by realizing a smooth cutting of a pilot hole in a backfilling material grouting pipe. SOLUTION: A recessed portion as a housing space formed on the front side of a backfilling material grouting pipe for grouting backfilling materials between a primary lining body and natural ground has a rotary cutter arranged retractably, a cutter rotating device 12 for rotating and driving the rotary cutter, and a cutter advance-retreat device 13. In addition, a torque detector 44 for detecting the cutting torque is provided on the rotating cutter, a displacement gauge 56 is provided for detecting the projecting speed of the rotary cutter from the displacement of a cutter advance-retreat cylinder 53 of the cutter advance-retreat device 13, and a cutting controller 10 is provided which controls the projecting speed of the rotary cutter by cutter advance-retreat cylinder 53 based on the detection signal of the torque detector 44 of a cutter rotating motor 35 of the cutter rotating device 12.

摘要： PROBLEM TO BE SOLVED: To provide a silo having a hopper of an easily designable and manufacturable structure with high strength and to decrease the number of discharging conveyors to one. SOLUTION: A silo main body 1 is provided with an annular inner hopper part 5 having an inner delivery port 12 and an annular outer hopper part 6 having an outer delivery port 13. An inner discharging port 17 for discharging the stored material under transportation is opened at one point on the transfer path of an inner table conveyor 15 for transporting the stored material 2 delivered from the inner delivery port 12. Outer discharging ports 18 for discharging the stored material under transportation are opened at two points on the transfer path of an outer table conveyor 16 for transporting the stored material 2 delivered from the outer delivery port 13. These discharging ports 17, 18 are aligned on a horizontal straight line 19. A single discharging conveyor 20 for receiving the stored material 2 and transporting the material out of the silo main body 1 is placed under the discharging ports 17, 18.

摘要： PURPOSE: To accurately destruct an article to be destructed in a preset distructing direction by preventing that the article to be destructed is destructed from destruction holes toward the outer surface thereof by setting the interval between a plurality of the destruction holes bored in the article to be destructed smaller than the distance from the respective destruction holes to the outer surface of the article to be destructed. CONSTITUTION: The spaced-apart distance between the destruction holes 20a bored in an article H1 to be destructed is set smaller than the distance from the destruction holes 20a to the outer surface 30 of the article H1 to be destructed. Therefore, the inner peripheral surfaces of the destruction holes 20a adjacent to destruction containers 2 and having no destruction containers 2 provided thereto become the free surfaces nearest to the destruction containers 2 and the impact force at the time of the melting and evaporation of fine metal wires acts in the direction separating the article H1 to be destructed along the line connecting the respective destruction holes 20a. Therefore, the article H1 to be destructed is prevented from being destructed from the destruction holes 20a to the outer surface 30 thereof and can be accuratly destructed in a preset destructing direction.
