摘要： A blasting cartridge includes a generally cylindrical blasting container, a blasting substance filled in the blasting container, a pair of leadwires contained in the blasting container, and a single thin metal wire connected to tip portions of the pair of leadwires. The leadwires and the thin metal wire are positioned within the blasting substance within the blasting container. The blasting substance is nitromethane, and the thin metal wire is formed of tungsten. With an electric discharge impact blasting apparatus, since the thin metal wire has a higher heating value than a copper wire because of its higher resistance and vaporizes at higher temperatures, it is possible to obtain a greater blasting force at lower voltages than with a blasting apparatus using a copper wire.

摘要： A novel primary or secondary battery whose active material for the negative electrode is composed of metallic gallium, gallium alloys or gallium oxide has first come into the world.Gallium has an electrochemical equivalent of 23.24, which is smaller than those of zinc (32.70) and cadmium (56.21). This indicates that when used as an active material for the negative electrode in batteries, gallium has larger capacity per unit mass than zinc and cadmium by respective factors of ca. 1.4 and 2.4. The potential of the reaction; Ga+6OH.sup.- =GaO.sub.3.sup.3- +3H.sub.2 O+3e.sup.- is obviously less noble than the voltage of hydrogen evolution and this means that a high-potential battery can be made. Due to the high hydrogen overvoltage of gallium, gallium ions in the solution can be precipitated as metallic gallium by electrodeposition. As a further advantage, no dendrite formation occurs during the electrodeposition unlike in the case of zinc. The high hydrogen overvoltage also contributes to the production of a battery that undergoes only limited self-discharge. What is more, gallium which has no toxicity presents few environmental problems.

摘要翻译： 一种新型的一次或二次电池，其负极活性物质由金属镓，镓合金或氧化镓组成，已经进入世界。 镓的电化学当量为23.24，小于锌（32.70）和镉（56.21）的电化学当量。 这表明，当用作电池中的负极的活性材料时，镓的每单位质量的量比锌和镉的相应因素大。 1.4和2.4。 反应的潜力; Ga + 6OH- = GaO33- + 3H2O + 3e-明显低于氢析出电压的高度，这意味着可以制造高电位电池。 由于镓的高氢过电压，溶液中的镓离子可以通过电沉积作为金属镓沉淀。 作为另外的优点，在电沉积期间不发生枝晶形成，这与锌的情况不同。 高氢过电压也有助于生产仅经受有限自放电的电池。 而且，没有毒性的镓会带来很少的环境问题。
