CONSTITUTION:The one 12 of a plurality of fluidized beds is heated by a fluidized bed heating mechanism 44. A part of a fluidizing medium the temperature of which is increased is introduced to the other fluidized bed 14 through a fluidizing medium flow passage 64 to increase temperature. In which case, the fluidizing medium in the same quantity as that of the fluidizing medium introduced to the other positioned adjacent to the other is supplied to the fluidized bed 12 by means of a fluidizing medium charge mechanism 40. By the feed and supply of the fluidizing medium to the adjoining fluidizing bed, the fluidized bed under operation incurs a heat loss, but a speed at which the adjoining fluidized bed is filled with the fluidizing medium the temperature of which is increased is regulated or an amount of a combustion substance charged in the fluidized bed during operation is regulated. By repetition of a series of cycles, the fluidized bed is capable of effecting hot start. Simultaneously with discharge of gas for fluidization to the other fluidized bed, a combustion substance is charged to start operation.

Abstract: PURPOSE:To obtain a prepreg for which an increase in cost caused by solvent loss and a change of the working atmosphere for the worse is improved by impregnating a sheetlike fibrous base material with a molten polyaminopolymaleimide fluid. CONSTITUTION:The aimed prepreg sheet is obtd. by impregnating a sheetlike fibrous base material with a molten polyaminopolymaleimide fluid. It is pref. that the viscosity of this fluid is 1,000cps or smaller. Resin impregnation characteristics to fibrous base material equal to those of the soln. impregnation method can be obtd. thereby. It is pref. that no org. solvent is incorporated, but if a small amt. thereof is added to reduce the viscosity of the molten resin and to ensure drapeness of the prepreg sheet, no large problem occurs since most of the solvent is kept in the prepreg. However, the amt. of the org. solvent should be 10wt.% or less based on the whole impregnation fluid and if it exceeds this value, a large amt. of solvent volatilization becomes conspicuous.
