Abstract: Disclosed is a positive electrode material for a lithium secondary battery. The positive electrode material includes a positive electrode active material formed of Li—[Mn—Ti]-M-O-based material including a transition metal (M) to enable reversible intercalation and deintercalation of lithium and molybdenum oxide. The positive electrode active material is coated with the molybdenum oxide to form a coating layer on a surface thereof.

Abstract: In the method, an upper mould is fixed on an upper portion of a base body, and a lower mould is provided. When the primary molding is performed, the lower mould moves up at a different speed. The beads are drilled during the primary molding. After the primary molding, the lower mould moves down slightly. Gases generated while a material for the beads is cured are discharged, and the lower mould moves up to secondarily mold the beads. The lower mould is positioned on a pin plate fixed to a piston shaft of a cylinder. Semi-circular recesses of the lower mould are provided with pin holes. While pins fitted into the pin plate enters into and exits from the pin holes, the beads are drilled. The pin plate moves down by descent of the lifting plate, and thus the pins escape from the molded beads.

Abstract: A method for coating thermoplastic resin beads for use in imitation pearls includes the steps of: applying to celluloid a surface treatment compound (A) dissolved into a mixed solution of acetone, ethylacetate, butylacetate, and benzene; coating the surface treated celluloid with compounds for an under coat and a mid coat, each compound being obtained by dissolving celluloid into a mixed solution of ethylacetate and amylacetate, and adding a pigment thereto; and coating the celluloid with a compound for a top coat (D) that is prepared by dissolving celluloid into ethylacetate, and adding a pigment thereto.
