Abstract: There is provided a solid electrolyte production method which can provide a solid electrolyte having a high ion conductivity at low cost with high productivity using a liquid-phase method. The method comprises drying a slurry by fluidized drying using media particles as a medium. The slurry includes a solid electrolyte comprising at least an alkali metal, sulfur atoms and phosphorus atoms as constituent atoms, or a precursor of the solid electrolyte, and a polar solvent.

Abstract: In a wiring board, on an insulating layer of an outermost layer, there are provided a plurality of strip-shaped wiring conductors which are partially provided with semiconductor element connection pads to which electrode terminals of a semiconductor element are connected, at positions which prevent the semiconductor element connection pads adjacent to each other from being laterally arranged, and a solder resist layer having openings for individually exposing the semiconductor element connection pads is adhered on the insulating board as the outermost layer and on the strip-shaped wiring conductors, wherein the solder resist layer internally contains an insulating filler, and the insulating filler is sunk below the upper surfaces of the strip-shaped wiring conductors.

Abstract: The invention provides a method of producing styrenic resin granulates including dry-compression-molding a powder of styrenic resin having a syndiotactic configuration at a compression pressure of 1-20 t/cm and at a molding temperature falling within the range of the glass transition temperature of the powder of styrenic resin to the melting point thereof, inclusive; and crushing the resultant molded product. High-quality styrenic polymer granulates can be produced in an industrially advantageous manner by means of a large-scale apparatus for producing styrenic polymer having a syndiotactic configuration.

Abstract: Disclosed is a method for producing a molding material, which comprises melt-extruding a styrenic polymer essentially having a syndiotactic structure or a composition containing the polymer to give strands, then rapidly cooling the resulting strands to thereby make the surface temperature of the strands not higher than the melting point of the styrenic polymer or the composition containing the polymer, and thereafter gradually cooling them to thereby make the surface temperature of the strands not higher than a temperature higher by 20.degree. C. than their glass transition temperature, and finally pelletizing the strands into pellets. The pellets produced have a high degree of crystallinity and can be well molded into good moldings.
