Abstract: A polymer treating method has the steps of: reacting a polymer compound with a reaction agent in a reaction vessel to generate a polymer treatment product; discharging the polymer treatment product containing the reaction agent from the reaction vessel; depressurizing the polymer treatment product; introducing the polymer treatment product into a degassing extruder; separating the reaction agent from the polymer treatment product through a vent box that is connected to upstream of the degassing extruder and that has a volume of equal to or more than that of the reaction vessel; and extruding the polymer treatment product from the degassing extruder.

Abstract: A method of treating a polymer compound has the steps of: mixing and agitating the polymer compound and a chemical agent in an extruder while controlling the inside of the extruder to be kept at a high temperature and a high pressure to have a reaction mixture containing a polymer treated product; supplying the reaction mixture continuously into a high-pressure container disposed following the extruder and retaining the reaction mixture at the high temperature and high pressure for a predetermined time; then supplying the reaction mixture continuously to a chemical agent separator to separate the polymer treated product; and supplying the separated polymer treated product continuously to a molding means to form it into a molded material.

Abstract: A magnetic disk device includes a magnetic disk, and a magnetic head slider. The slider has a magnetic head, a plurality of surfaces which are formed sequentially from an adjacent side to a magnetic disk, and a slider rail surface which is arranged near an air flow-out edge on a nearest surface of the plurality of surfaces. The slider rail surface includes a long sideways rail surface on an air flow-in side and a lengthwise rail surface on an air flow-out side. The nearest surface of the plurality of surfaces is arranged only in a center area with respect to a width of the slider near the air flow-out edge and has a width substantially less than the width of the slider. An area of the long sideways rail surface is larger than an area of the lengthwise rail surface.

Abstract: The object of the present invention resides in providing a method and instrument of polymer processing treatment, wherein a sudden pressure change due to expansion by gasification of a reactant when it is exhausted from a reacting extruder is given in a little amount to a molding machine for a treated substance, and a change in the amount of the material supplied to the molding machine and a variation in molding are little, and hence continuous and uniform molding is possible. That is, the method of the present invention resides in a method of polymer processing treatment, which includes the steps of: reacting a polymer with a reactant under mixing and stirring at a high temperature and a high pressure in the inside of a reacting extruder to produce the treated substance; introducing said treated substance and a remaining reactant into a reactant-separation tank to separate the treated substance and the reactant; and molding the separated treated substance.
