摘要： PURPOSE:To obtain a powerful shooting echo by simultaneously injecting only smoke without large percussion sound at the time of shooting a bullet by providing a small hole having a function for injecting or sucking the smoke. CONSTITUTION:A small hole B is formed at a part of an inner barrel A, and a periphery of the hole is sealed by a smoke storage tank D adhered with an external injection port C. First, smoke substance of smoke screen, etc., is ignited and injected from the port C. The tank D is fully filled with concentrated smoke, which is fed from the hole B into the barrel A. When a bullet is shot, the smoke in the barrel A is simultaneously injected by pressure of the air, the concentrated smoke is sucked by the hole B by the flow of the air to become the state for waiting next shooting of a bullet. It can be shot until the smoke in the tank D becomes thin while repeating such a state. A position of the hole B formed at the barrel A is preferably nearer to a muzzle since the pressure of the air is continued, but automatically decided from the relationship to designing.

摘要： PURPOSE:To fire a projectile efficiently employing only light gas by a method wherein an injecting tube, generating high-temperature produced gas, is attached to a barrel for firing the projectile under an eccentric condition to provide the high-temperature produced gas with rotating motion and separate it into heavy constituent and the light gas surely by the mass of them. CONSTITUTION:When a switch 2 is put ON after loading a projectile 15 into a barrel 51, chemical reaction between aluminum and water in an electric thermochemical unit 80 is generated suddenly and high-temperature produced gas is generated. Then the high-temperature produced gas is injected into a bore 51a from the cylindrical hole 110 of an injection tube 110 through a breech groove 112. In this case, the high- temperature produced gas is rotated by the eccentricity between the injection tube 110 and the barrel 51 and becomes the condition of vortex. As a result, heavy constituents in the high-temperature produced gas is stagnated on the wall surface 112a of the breech groove 112 and is cooled by the wall surface 112a of the same. Accordingly, the heavy constituents in the high-temperature produced gas is separated surely from the light gas by the mass of the same. According to this method, the projectile can be driven efficiently utilizing the light gas and super high-speed firing can be effected in a low-temperature condition also.

摘要： PURPOSE:To obtain nuclear fusion energy of applied electric energy or more and to reduce in size a power source by performing nuclear fusion reaction with heavy water, and accelerating a bullet by high pressure heavy water vapor obtained thereby. CONSTITUTION:Heavy water 28 is filled in a reaction chamber 16, and a missile 14 is loaded in a gun barrel 12. The gun barrel 12 is engaged with the missile 14 to eliminate leakage of the water 28. Then, when an anode 18 and a cathode 22 are conducted by a power source 26, heavy hydrogen in the water 28 is absorbed in large quantity to the cathode 22, compressed, and the hydrogens are nuclear-fused. Thus, helium, neutron, tritium and hydrogen are generated. The generated high energy particles have kinetic energy of 1-2 million electron volts, collided with the cathode 22 and a cylindrical member 24 and with heavy hydrogen. Accordingly, the heavy water eventually becomes high pressure heavy water vapor. The missile 14 is ejected from a gun tube 10 at a high speed by means of the pressure of the high pressure heavy water vapor.
