摘要： PROBLEM TO BE SOLVED: To apply a coating of a high-melting corrosion preventing coating material to the inside surface of a gun barrel for well joining the coating material to a gun barrel material without giving great thermal influences to the gun barrel.
SOLUTION: The coating of the corrosion preventing coating material 9 is applied to the inside of the gun barrel 1 by a plasma spraying. Concurrently with plasma spraying, a laser beam 7 is guided onto the inside surface 5 of the gun barrel for melting a gun barrel region 10 just subjected to coating or subject thereto from now in proximity to the surface to form a melting liquid 11 containing the gun barrel material and the coating material melted in the region 10 in proximity to the surface of the gun barrel 1. The melting liquid is hardened when the laser beam 7 is further moved.

摘要： PROBLEM TO BE SOLVED: To surely repair a gun barrel having damage in coatings and damage caused by corrosion by a simple and inexpensive method, without weakening the important gun barrel.
SOLUTION: For example, a proper coating material including chrome is stuck to a coating damage and/or corrosion damage area 3 existing on an inside surface of the gun barrel 1 by buildup welding. Postprocessing is mechanically performed when necessary. Buildup is performed by a laser buildup welding or plasma buildup welding of a buildup welding laser. The temperature is adjusted so that thermally influenced zone in a wall of the gun barrel becomes 1 mm or less at the maximum.

摘要： PROBLEM TO BE SOLVED: To provide a method for forming a gun barrel for armament having a hard chromium layer inside thereof. SOLUTION: In order to improve the thermal shock resistance of a chromium layer 2, a hard chromium layer is thermally post-treated before using a gun barrel 1 for armament. The temperature is selected so that the chromium crystal formed during electroplating is re-crystallized to thereby obtain a bcc-type recrystallization structure. The hardness of the chromium layer is remarkably reduced, thereby improving its ductility.

摘要： PROBLEM TO BE SOLVED: To provide gun barrel arms avoiding approximately a stroke effect of the gun barrel, dispensing with a guide slot in a cradle tube, and slidably journaled in the cradle tube capable of replacing the gun barrel.
SOLUTION: The gun barrel (2) is journaled to first and second slide bush bearings arranged on the ends on the muzzle side and the rear body side of the cradle tube (3). The first slide bush bearing is constituted without the stroke effect and has a tube bush (7), and the outside face (8) of the tube bush is journaled movably by sliding in the cradle tube. Each tube bush has inside four groove-shaped recessed parts (9) distributed and arranged uniformly in the circumferential direction. Four strip-shaped projections (10) are arranged on the gun barrel, and the projections are inserted into the groove-shaped recessed parts on the tube bush. Plays for absorbing extension of the gun barrel generated at the firing time are provided between the outside surface (11) coupled with the gun barrel in a complementary shape and the inside surface (12) of the tube bush, and between a strip head (13) and the inside surface (14) of the groove-shaped recessed parts.

摘要： PROBLEM TO BE SOLVED: To guarantee ignition and necessary safety release of a safety device when reaching a predetermined propellant pressure while maintaining a function of smoothbore ammunition. SOLUTION: A changeover piston 6 of this gas pressure switch 1 is held inside a housing of the switch by a safety pin 7. When propellant burns and when reaching a predetermined piston force, the changeover piston 6 is released by shearing of the safety pin 7 to form contact between two contact pins 5. Before one changeover process, the gas pressure switch is electrically opened until the predetermined pressure. The switch is closed within 15 ms after pressure supply, and the switch remains in the closed position until the ignition of the explosive charged propellant. The changeover piston is surrounded by a deformable membrane 8 connected to the switch housing, and the membrane secures the changeover piston in a contact position with the contact pins 5 in a complementary shape after the severing of the safety pin.

摘要： PROBLEM TO BE SOLVED: To prevent a conventional high load from acting on a portion of a muzzle brake detachably linked with a gun barrel at the time of discharging. SOLUTION: This muzzle brake (2) has a pipe piece having openings (16) around its periphery, and a jacket pipe (4) opposed to a muzzle with a diameter for surrounding the pipe piece, and having a gas outflow opening (17) extending vertical to a cavity axis (15). At the time of discharging, a muzzle area (3) itself of the gun barrel is formed as a part of the muzzle brake so that as small load as possible acts on the portion detachably linked with the gun barrel (1). That is to say, a large number of openings (16) are formed in a ring form around the gun barrel, and the jacket pipe having the slit-shaped gas outflow opening (17) is fixed on the muzzle area.

摘要： PROBLEM TO BE SOLVED: To miniaturize and lighten the weight of a control unit for guiding a piston rod for operating a closing wedge. SOLUTION: The control unit 11 is provided with a changeover rod 13 and a detent pawl 17, a cam 16 is fitted inside a notch 18 of a control rod, and the cam press-fits the detent pawl in the inside of a lock groove 19 of the changeover rod at the initial position of the control rod 15. The changeover rod cannot slide axially, the control rod slides in the direction of an opening part of a gun barrel 3, and the cam swings the detent pawl so as to come out from the lock groove. The lengths of the piston rod 8 and the changeover rod are so selected that, when the gun barrel 3 advances, the closing wedge 7 moves to a position already opened by the axial sliding of the rods 8 and 13, and then the control cam 10 brings about the sliding of the control rod and the swinging of the detent pawl toward the release position.

摘要： PROBLEM TO BE SOLVED: To provide a discarding sabot in which separation of sabot segments from a projectile is not prohibited by a seal band.
SOLUTION: This device comprises a plurality of sabot segments 9 parted by separation seams 11, and disposed in a circumferential direction. Each is provided with a seal flange 7, and a sabot range 8 of a truncated conical form is continuously formed on the back side of the seal flange. A seal band 12 comprising plastic is fixed to an outer circumferential surface of it. The seal band 12 is composed of a plurality of seal band segments 14 and 14', parted by separation seams 13, and disposed in the circumferential direction. Each seal band segment corresponds to the sabot segment 9 to be coupled with the sabot segment 9 in a complementary form and/or friction coupling. The seal band segments are integrally coupled on the back side by a vulcanized layer 18.

摘要： PROBLEM TO BE SOLVED: To provide a simply structured wedge breechblock capable of automatic release of a breechblock for fast continuous firing without requiring an additional external driving device.
SOLUTION: In the wedge breechblock for an arm 1 having a gun barrel 3 and a rear body 4 retreatable against a cradle and equipped with a closure wedge 7, provided in the rear body in a manner transversely slidable against a bore shaft 6, which is operatable with a releaser shaft 8, a curve passage 15 is provided at a guide device 12 fixed on the cradle for guiding an interlocking element 11 in a bolt shape. The interlocking element 11 rotates the releaser shaft 8 when the gun barrel 3 moves forward, and the releaser shaft itself acts on the closure wedge 7 via, for example, a releaser lever 9 to move the closure wedge 7 at its released position.
