| 内容記述 | The authors, in this paper, give outlines about the apparatus of the pipe-harpoon projector for electrical whale-catching and about the results of its tests. It is cleared that the shock-waves have transmitted in 37.4 milli-sec. through copper lead-wire from its harpoon-tieing end to the other end and that the harpoon flys only 5 meter during this period. The impact which occurs on the cable-rope is given as follow ; Ρ=υ√{ρEg}. where Ρ＝impact, υ＝the component of harpoon velocity in the direction of the rope veered away, ρ＝mass of copper wire in unit length, E＝Young’s modulus of copper, g＝gravitational acceleration. Using this formula, it is calculated that the impact comes up a large value ranging about 2 tons in thick cable-rope for an old-type electric harpoon, and, even in our thin cable-rope, the impact is 354 kg. In order to keep off the knots on a copper lead-wire by shock, the authors devised the new type connector of lead-wire in which electricity was connected perfectly and mechanical shock-waves were intercepted. And, when these connectors were used, the tests were satisfactory to project harpoon and cable-rope. | |||||
