摘要： The present invention provides a method capable of continuously efficiently producing a 2-hydroxycarboxylic acid oligomer while effectively removing the water contained in a raw material and the water produced by dehydration reaction. In production of a 2-hydroxycarboxylic acid oligomer by supplying a 2-hydroxycarboxylic acid to a reaction system, a dehydration system is provided between a raw material supply system and a polymerization reaction system so as to remove the water contained in the raw material and the water produced in the polymerization reaction system. As a result, the raw material in the dehydration system is concentrated and then supplied to the polymerization reaction system.

摘要： The apparatus of the invention is an injection molding apparatus of a type adapted to cool a molten metal under shearing by an extrusion screw in a substantially vertical chamber into a semi-solidified slurry and then inject the semi-solidified slurry discharged from a discharge port at the lower end of a channel into molding plates, in which a clamping device is adapted to open or close a movable plate relative to a stationary plate in the horizontal direction, and a connection member having, at the inside, a vertical first channel and a second channel extending in the horizontal direction from the lower end of the first channel and in communication with the stationary plate is connected to the discharge port at the lower end of the chamber. Since this can inject and mold light metal molding products of high quality with less pore or shrinkage without excessively enlarging the size for the height of the apparatus, casting products of high quality can be obtained at a reduced cost by injection molding.

摘要： A bladder for a vulcanizer includes, as a constituent member, a low elongation material with stable properties at vulcanization temperatures. During a vulcanization-molding process, the bladder is pressed against the inner surface of a green tire using a pressurized medium. The pressurized medium can be at vulcanization temperatures. The bladder has substantially the same shape as the inner wall surface of the tire that is formed using the bladder. As a result, irregularities in the shape of the inner wall surface of a tire rarely occur, and the frequency of exchange of bladders can be reduced. The vulcanizer bladder can include a conductive material or a magnetic material, both of which can be heated by using an induction heating coil. The use of both heat from the pressurized medium and heat generated in the bladder to vulcanize a green tire can shorten the period of time required for vulcanizing-molding.
