摘要： PURPOSE:To smoothly supply raw materials with an approximately uniform distribution by respectively and specifically disposing openings in the lower parts of an outer cylinder which is supported inclinedly by a vibrating device and an inner cylinder which is rotatably supported therein and receives the raw materials. CONSTITUTION:This supplying device 20 has double cylindrical structures consisting of the outer cylinder 21 and inner cylinder 22 having the downward slit-shaped opening 23B and longitudinal opening 24B respectively in the lower parts ans is supported with inclination from horizontal at an angle theta. The entire part of the device 20 is vibrated by the vibrating device 28 at the time of accepting the pellets 12 supplied from a hopper 10 via the opening 23A, 24A of the outer cylinder 21 and the inner cylinder 22. As a result, the pellets 12 from the opening 24A are rolled and the lower positions in the inner cylinder 22 are successively filled with these pellets and, therefore, the pellets are distributed approximately uniformly in the longitudinal direction. Next, the opening 24B aligns to the opening 23B when the inner cylinder 22 is rotated about 90 deg. and, therefore, the pellets 12 around the opening 24B fall to a lower basket by passing the opening 23B. At this time, the distribution of the pellets 12 around the opening 24B is uniform and, therefore, the falling distribution into the basket is made approximately uniform as well.

摘要： PURPOSE:To develop a crucible for evaporating uranium where evaporation efficiency can be improved without deteriorating heat insulating effect by arranging mixedly tungsten powders and tungsten blocks in an evaporating crucible where the uramium is melted by irradiating electron beams. CONSTITUTION:Plural tungsten blocks 7a are disposed so as to be in contact with the whole face of inner wall in the crucible body 1 and further, on the tungsten blocks 7a, the tungsten fine powders 5 and particles 6 are charged. On the tungsten fine powders 5 and particles 6, uramium pellets 4a are placed and this is melted with the heat of the electron beam A and penetrated into the tungsten fine powders 5 and particles 6. In such a manner, when the tungsten fine powders 5 and particles 6 coexist with the molten uranium 4, since the solid tungsten fine powders 5 and particles 6 become a resistor to the heat convection of the molten uranium 4, consequently, this becomes the same condition as increasing the viscosity thereof, and heat conductivity and heat convection of the molten uranium 4 are restrained, and the evaporation efficiency is promoted.
