摘要： PURPOSE:To make an ammunition main body erect with the top part directed upward correctly even on a non-leveled ground, by canceling a state of engagement of the base end part of an elastic member not coming into contact with the ground, with the periphery of the ammunition main body, and by making the elastic member withdraw thereby from the ammunition main body. CONSTITUTION:At the time of landing, a ring 17 comes into contact with the ground surface and a coil spring 18 contracts. Therefore a pin 15 is also moved downward and the lower end part 15a thereof comes out of a joining hole 14b. Then the restraint of a leaf spring 13 is removed. The shape of the leaf spring 13 is to be restored to a straight line. Therefore the fore end part 13b thereof separates from an ammunition main body 11 and develops and it comes into contact with the ground surface. Then the ammunition main body 11 starts to rotate. A rubber band is broken, the leaf spring 13 develops further and the ammunition main body 11 inclines. At this time, the fore end parts 13b of several leaf springs 13 are to make the ammunition main body erect. When the ammunition main body 11 inclines at a prescribed value or more, it transfers to a state of stable erection. At this time, the leaf springs 13 not being in contact with the ground surface fall off the ammunition main body 11.

摘要： PURPOSE:To permit the employment of a loader both for loading a bullets and propellant by a method wherein an one-side bending chain is driven by switching the moving stroke of a head and the speed of the same by two steps. CONSTITUTION:Upon loading a bullet, the bullet 11 is put on a tray 10 and links 8, 9 are driven whereby the tray 10 is moved horizontally in parallel to a loading starting position on the axial line 3 of a gun and is engaged with the opening 3c of a breech ring. Subsequently, bi-position cylinder 17 is driven to dispatch an one-side bending chain 13 with a high speed while the bullet 11 is pushed by a head 13a and is sent into a releasing position A in the barrel 3e of a recoiling body. Then, the bullet 11 is slid by a slight distance and arrives at a biting position B whereby the bullet 11 is loaded into the barrel 3e. Upon loading propellant, the tray 10 is moved to the loading starting position in the same manner and, then, the bi-position cylinder 17 is driven to dispatch the one-side bending chain 13, however, the chain 13 pushes the propellant 12 to a propellant loading position C with a low speed to load the propellant 12 into the barrel 3e.

摘要： PURPOSE:To suppress a gas differential pressure generated in a gun powder chamber by specifying a density of a columnar destrolyable vessel of a specified composition such as nitrocellulose, etc., and specifying a weight of igniter explosive and a burning surface area of the igniter explosive for shooting powder of a specific weight. CONSTITUTION:Main components of a columnar destrolyable vessel 1 1 have nitrocellulose, pulp, resin and additive, and its density is set to 0.8-1.2g/cm . A weight of igniter explosive to 1kg of shooting powder is set to 5-30g, and a burning surface area of the igniter explosive to 1kg of the shooting powder is set to 25-200cm . The condition of 0.8g/cm of more of the density is indispensable to realize burning characteristics of the vessel 1, and the density of 1.2g/cm or more is not preferable due to generation of burning residue. Further, the conditions for specifying the weight of the igniter explosive and the surface area of the burning for 1kg of the shooting powder are preferable to suppress a differential pressure generated at the time of shooting in high gas pressure range, and a differential pressure reduction can be realized by devising both the material and the igniter explosive of the vessel 1.
