摘要： PURPOSE:To obtain an electronic component sealed molding which is excellent in moisture resistance and solder resistance, and especially excellent in moisture resistance after being dipped in a solder bath by making specific independent pores exist in the resin part of a molding, and making the surface layer of the compact dense. CONSTITUTION:When an electronic component is sealed with a PAS resin compo sition, independent pores of 50-300mum in largest pore diameter are made to exist at the rate of 1-5volume% at the resin part of this molding, and besides the surface layer of the compact is made dense. For PAS resin, the one which has repeat unit of p-phenylene sulfide by 50weight% or more as the main constit uent unit of polymer is desirable. To obtain an electronic component sealed molding wherein independent pores of 50-300mum in the largest pore diameter are formed at the rate of 1-5volume% at the resin part of the compact and the surface layer of the compact is dense, it is important to set the injection molding maintenance pressure to lower pressure, but the conditions of these injection moldings vary with the composition of a resin composition, the type of an injection molding machine, the size of a mold, etc., so it is desirable to set the optimum conditions by trying it beforehand.

摘要： PURPOSE:To prepare the title molding at a low cost in a short time with a small-size oven, by removing a viscosity modifier from a spherical molding comprising petroleum- or coal-derived pitch and a viscosity modifier to prepare a porous molding and baking the porous molding in a particular heater for activation. CONSTITUTION:A di- or tricyclic arom. compd. (B) having a b.p. of 200 deg.C or above is removed from a spherical molding comprising 100 pts.wt. petroleum- or coal-derived pitch (A) and 5-50 pts.wt. component (B) as a viscosity modifier to prepare a porous molding. The porous molding is then made infusible to prepare an infusible spherical pitch. This molding is baked at 600-800 deg.C in a first-stage fluidized bed 2 of a two- stage fluidized bed activator 1 with a waste gas from a second-stage fluidized bed 3, thereby preparing a spherical carbon molding. After the activated molding of the previous batch is transferred outside the oven to empty the oven, the carbon molding is transferred to the empty fluidized bed 3, where the carbon molding is activated at 800-1200 deg.C with a heated activation gas at an ascending velocity not higher than the terminal fluidization gas velocity of the spherical activated carbon molding of the fluidized bed 3 and not lower than the incipient fluidization gas velocity of the infusible spherical pitch molding, thereby preparing pitch molding as spherical activated carbon molding.
