摘要： PURPOSE:To obtain a metal gasket which does not cause creep at its sealing edge nor cause damages to a valve seat even if it is used for a long time under a high temperature in the state that a valve is closed. CONSTITUTION:A metal gasket of this invention is manufactured as follows. At first, a nickel plating 3'' having a thickness of several mum is appied over the surface of a base 3' of stainless steel by immersing the base 3' in a bath of nickel chloride, and then a copper plating 3''' having a thickness of several mm. and a hardness of 180-220Hv is applied over the nickel plating 3'' by immersing the same in a bath of copper pyrophosphate added with a sulfuric compound containing additive. After appplying the copper plating 3''', heat treatment is applied at 250 deg.C for 20min-3hr so as to increase the hardness of the copper plating 3''' to 100-180Hv. In case that a metal gasket manufactured as above is used for a long time at a high temperature in the state that a valve is sealed by a load acted thereto, its sealing edge portion has a high resistance against creep, so that the stainless steel 3' does not come into direct contact with the valve seat. Thus, it is enabled to improve durability of the seal.

摘要： PURPOSE:To fly a flying object at a higher speed. CONSTITUTION:A first group of solenoid coils 3, 4 and a second group of solenoid coils 5, 6 are previously energized, and, after passage of a flying object, gas thereafter is made to be a plasma with laser. This plasma armature 9 is compressed in the length direction of rails 1, 2 by magnetic force of the first group of the solenoid coils 3, 4 and the second group of the solenoid coils 5, 6, plasma density is increased, and simultaneously current density is also increased. Thereafter, the first group of the solenoid coils 3, 4 is switched off and the flying object is accelerated in two-stages by the compressed plasma armature 9. Since acceleration force, namely, Lorentz's force can be determined by multiplying magnetic flux by current density, the increase of the magnetic flux and the current density is effective for flying the flying object.

摘要： PROBLEM TO BE SOLVED: To introduce a pellet fuel that is cut by a cutting device into the pellet injection groove of a rotator without causing damages to the fuel. SOLUTION: An injection device is provided with a cutting device 5 for cutting fuel that is cooled and hardened at an extremely low temperature into a pellet shape, a rotator 6 that is arranged nearly horizontally at the lower portion of the cutting device 5, and a pellet fuel injection groove 8 that is formed along the centrifugal direction of the rotator on the upper surface of the rotator 6. Also, the injection device is provided with a guide member 10 for guiding the pellet fuel that is cut by the cutting device 5 into the pellet fuel injection groove 8 on the upper surface of the rotator 6.

摘要： PURPOSE:To make it possible to obtain a large accelerating force and a large magnetic flux density and thereby to improve an additional acceleration performance of a flying body. CONSTITUTION:When a flying body 7 given initial-stage acceleration by a gas gun comes in between augment rails (inside) 6 and 61 through an introducing tube, a capacitor l for initial plasma ignition is turned ON and a voltage is applied between the augment rails. By turning arm accelerating gas in the rear of the flying body 7 into plasma by a laser, thereafter, a current is made to flow through one inside augment rail 6 a plasma armature 8 the other inside augment rail 61 and the flying body 7 is accelerated additionally by a Lorentz force at that time. Since the plasma is kept, in this condition, in a state of a higher plasma density than the plasma obtained by using the whole of the augment rails, switchover is made from the capacitor 1 for initial plasma ignition to a power source 3 in this state. Thereby it is made possible to make the maximum current flow before the plasma spreads (in other words, while the plasma is in a state of not being expanded, but being collected), a large accelerating force and a large magnetic flux density are obtained and thus an additional acceleration performance of the flying body 7 is improved.

摘要： PURPOSE:To prevent fluid leaks by detecting fluid that leaks from the high pressure side conduit to the low pressure side conduit through valve seat at the time of the valve actuation, and if the fluid leakage exceeds the specified value, the valve is actuated to cause a bellows to expand to press the valve plate against the valve seat. CONSTITUTION:The valve apparatus can be closed airtight at the high and low pressure side conduits 1, 4 by actuating a valve plate 10 to the closed position in a valve body 2 which is disposed between the high and low pressure side conduits 1, 4, and causing a bellows 17 to expand toward the valve plate 10 to press a valve seat 11 of the bellows 17 side against the valve plate 10. In such a construction, the amount of He leakage from the high pressure side conduit 1 to the low pressure side conduit 4 through the valve seat 11 is detected at the time of the valve closure actuation by a He leak detector 26. The detected signal X is supplied to a reducing valve 22, and if the amount of He leakage exceeds the specified value, the reducing valve 22 is actuated to increase the pressure in the bellows 17. By this constitution, fluid leaks from the high pressure side conduit 1 to the low pressure side conduit 4 is prevented.
