    Abstract: PROBLEM TO BE SOLVED: To improve productivity remarkably, to prevent the lowering of a yield due to a defective measurement precision, and to improve quality by installing a specified number of means which distribute a resin to discharge openings and regulate the volume variably at the tip of a screw housing cylinder. SOLUTION: A distribution die 3 for distributing a resin to discharge openings is connected to the tip of the screw housing cylinder of a kneading extruder 1. A molten resin composition is injected into one or more means for regulating the volume variably through the die 3 and measured. The measured molten resin is supplied to tablet molding dies 5a, 5b having one or more cavities. The composition, after being pressure-molded, is cooled and ejected upward by an ejecting plunger pestle 12, and high-quality tablets 14 are discharged. In this way, productivity is improved remarkably, the lowering of a yield due to a defective measuring precision is prevented, and the high-quality tablets 14 can be produced.

    Abstract: PROBLEM TO BE SOLVED: To improve productivity while assuring stable physical properties of a product and to maintain a production yield and a shape accuracy at high levels by continuously melting a resin, simultaneously supplying and filling a molten resin composition to and in one or a plurality of cavities, and sequentially conveying the compositions. SOLUTION: A resin composition is kneaded while heating and melting the composition in a kneading extruder 1, cast and filled in a mold 4 capable of changing a length of a round bar by a sealing member movable in the cavity from a mouth 3, and a completion of charging and metering is sensed from a discharging pressure of the extruder 1 by a pressure gage 2. Composition discharging is suppressed by the completion. A mold 4a is moved to a position of a discharging port of the mouth 3, conveyed to a molding machine 5a by a conveyor unit 10, and pressurized and cooled by a pressurizing member 7 of a hydraulic cylinder 6. The molten composition after the pressurizing and cooling is lifted by a lifting member 9 of a hydraulic cylinder 8 to recover a resin molding. Thus, stable physical properties of the product are assured, high productivity and a high yield are maintained, and a shape accuracy can be enhanced.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for the production of a color filter by which a means to apply three colors of R, G, B at a time through a nozzle having a plurality of injection holes is realized, the number of total processes is decreased significantly, and the color filter of high quality can be produced at a low cost. SOLUTION: The color filter is produced by forming a color pixel film in strips form in the pixel part in between a black matrices on a substrate. In this a method, after the color pixel film is formed in stripes, the upper part of the color pixel film is removed.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for preparing a granular material excellent in measuring accuracy and generating a few amount of a fine powder with improved productivity while maintaining stable resin characteristics by setting a grain size within a specific range and a variation of its bulk density within a specific range. SOLUTION: The thermosetting resin granular material is obtained by granulating a molten resin composition kept in a fluid state, cooling and solidifying it, and has a particle size ranging from 0.5 to 5 mm and a variation of its bulk density within ±10%. A thermosetting resin component such as an epoxy resin, a curing agent component such as a phenol novolak resin and 60-95 wt.% of an inorganic filler such as crystalline silica are compounded to give a resin composition. The resin composition is thrown into a kneader 1 and melt-kneaded and discharged by an extruding force of a screw 3 from a discharge opening 4 onto a cooling belt apparatus 5. It is passed between the cooling belts, stretched into a plate, cut into a prescribed size, through into a granulating apparatus 7 equipped with a base part rotating blade 8, a side part rotating blade 9 and a cooling jacket 10 and subjected to a treatment to give resin granules from a takeout opening 11 of resin granules.

    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.
