    Abstract: PROBLEM TO BE SOLVED: To prevent an adhesive from protruding from the edge of a sealing frame body by applying the adhesive to a semiconductor package sealing frame body or a semiconductor package substrate by a screen method and making the sealing frame body adhere to the substrate. SOLUTION: A screen printer is used as an adhesive application means 5 applying adhesive 6 to a prescribed region on the substrate 3. The screen printer is provided with a screen 14, and the screen 14 has a mesh part 15 whose form is the same as the adhesive applied region. Multiple small holes are given to the mesh part 15. When a squeegee 16 is moved, adhesive 6 on the screen 14 falls down through a small holes and is applied on the substrate 3. Thus, the adhesive 6 is prevented from protruding from the edge of the sealing frame body, and the adhesive 6 is prevented from covering a connection part between a conductor pattern and a semiconductor chip. Consequently, the conductor pattern and the semiconductor chip can be connected as they are.

    Abstract: PROBLEM TO BE SOLVED: To obtain a tablet of high quality by distributing resin from a screw- containing cylinder of a kneading extruder to a plurality of discharge ports, and injecting it in a tablet mold having a plurality of cavities, thereby, remarkably improving productivity. SOLUTION: Resin composition is fed to a heating cylinder 2 by rotation of a screw of a kneading extruder 1, and kneaded while being heated and melted. It is quantitatively cut by a cutter 4 provided near a discharge port of a distributing die 3 by an urging force of the screw, and then charged in a tablet mold 8 having one or a plurality of cavities. After the charging is completed, a tablet mold holder 5 is moved. Then, when the mold 8 is arrived at a position of the discharge port of the die 3, the holder 5 is stopped. After the resin charged in the mold 8 is pressurized by an upper plunger 11 and sealing member 99, it is cooled. This is lifted by a thrust plunged 12.

    Abstract: PURPOSE:To obtain a thermoplastic resin compsn. having excellent rigidity and impact resistance with improvements in the tensile toughness and chemical resistance of a thermoplastic styrene resin by blending the thermoplastic styrene resin with a modified polyolefin resin and a specific modified graft copolymer. CONSTITUTION:A thermoplastic resin compsn. comprises the following components [A] to [C]. The component [A] is a thermoplastic styrene resin. The component [B] is a modified polyolefin resin prepd. by grafting a polyolefin resin with an alpha,beta-unsatd. carboxylic acid or a deriv. thereof, the amt. of which is 0.1 to 15wt.%, based on the polyolefin resin. The component [C] is either a modified graft copolymer prepd. by graft copolymn. of a diene rubber with a monomer mixture of an oxazolyl group-contg. vinyl monomer and other copolymerizable monomer, or a modified graft copolymer compsn. comprising the above-mentioned modified graft copolymer and a copolymer of the remaining monomers. The blending ratio is such that [A]/[B]=-5/95 to 95/5 (wt. ratio) and the amt. of the component [C] is l-100 pts.wt. per 100 pts.wt. in total of the components [A] and [B].

    Abstract: PURPOSE:To obtain a thermoplastic resin composition having good compatibility among components and excellent in impact resistance, tensile toughness, and rigidity by mixing a thermoplastic styrene resin with a modified polyolefin resin and a modified vinyl polymer having oxazolyl groups. CONSTITUTION:This composition comprises a thermoplastic styrene resin (A) (e.g. a rubber-reinforced styrene-resin), a modified polyolefin resin (B) obtained by grafting an alpha,beta-unsaturated carboxylic acid or a derivative thereof onto a polyolefin resin (b) (e.g. an ethylene/alpha-olefin copolymer rubber) in an amount of 0.1-15wt.% based on the resin (b), and a modified vinyl polymer (C) having oxazolyl groups, wherein the (A) to (B) ratio is 5/95 to 95/5 by weight and the amount of (C) is 1-100 pts.wt. per 100 pts.wt. the sum of (A) and (B). The component (C) is a copolymer of a vinyl monomer having an oxazolyl group (e.g. 2-propenyl-2-oxazoline with a copolymerizable vinyl monomer (e.g., acrylonitrile).

    Abstract: PURPOSE:To stabilize the fluidization of a fluidized bed apparatus by a method wherein cylindrical bodies having an inlet hole and an outlet hole for a running thread or band material are partly formed of perforated plates or porous plates with fine through-holes leading to the outside of the fluidized bed and having diameters smaller than the mean diameter of fluidized particles. CONSTITUTION:A running thread- or band-like material, e.g. a carbon fiber precursor, is introduced into a fluidized bed 1 through an inlet hole 6 provided in the side wall of a frame 2, continuously or intermittently travels through the fluidized bed 2 as it is kept in specified conditions, and goes outside through an outlet hole 7 provided on the side of the frame 2. The inlet and outlet holes 6 and 7 each consist of a cylindrical body 8 which is partly formed of a perforated plate or a porous plate 9 with fine through-holes leading to the outside of the fluidized bed 1 and having diameters smaller than the mean diameter of fluidized particles. Thereby, the fluidized particles deposit and naturally form a dike surrounding the material to be treated, so that an excellent sealing effect is produced and the fluidized particles are kept from leaking.

    Abstract: PURPOSE:To provide a heating furnace with a resistance heating element, the life of which can be substantially prolonged by completely suppressing evaporation of graphite from a surface of the heating element. CONSTITUTION:A carbon fiber thread layer 3 comprising a laminate formed by winding of carbon fiber threads, and a sheet-shaped graphite layer 4 comprising a laminate formed by winding of a sheet-shaped graphite cover in this order an outer surface of a cylindrical-shaped resistance heating element 2 which is formed of graphite and has an inlet 9a and an outlet 9b for a thread Y. The insulating members 5 which comprise a compact of boron nitride is provided between the sheet-shaped graphite layer 4 and the resistance heating element 2 on the opposite ends thereof. Accordingly, the insulating members 5 prevent carbon vapor having evaporated from an outer surface of the resistance heating element 2 from leaking outside the element, so that a heating furnace is provided to have a heating element 1, the life of which is substantially prolonged.
