Inventor: ABE YASUSHI
IPC: G03G21/10
Filed: 1994-11-24
Abstract: PURPOSE: To manufacture a permanent magnet member for a highly accurate magnet roll, whose deflection is small, in a short molding cycle by injecting and filling the mixed material, wherein magnetic particle and bonding material are main components, and thereafter ejecting the molded body from molding dies at the same time when the molding dies are opened. CONSTITUTION: The mixed material, wherein magnetic powder and bonding material are main components, is injected and filled in a molding cavity 13 in the fused state (e.g. at 250 deg.C). After the injection and filling, a movable die 12 is lifted up under the state (the central part is in the unsolidified state), wherein the outer surface and the vicinity of the molding body in the molding cavity 13 are not solidified. Thus, ejector rods 8 are lifted by the energyzing force of a compressing coil spring 23, and the molded body is ejected from the molding cavity 13. Under this state, the molded body is supported by the ejector rods 18 and located at the position at the approximately equal distance from a fixing die 11 and the movable die 12, respectively.

Filed: 1988-11-15
Abstract: PURPOSE:To make it light and tough, and improve the bending strength by adhering and laminating one or more synthetic paper sheets of non-directional orientating property containing a predetermined wt.% or more of aromatic polyamide fiber, on the surface of a molding comprising porous polymetamethyl acrylate having the air bubbles of specific apparent density and the copolymer thereof. CONSTITUTION:At least, one synthetic paper sheet of non-directional orientating property containing 49wt.% of aromatic polyamide fiber is adhered and laminated on the surface of a molding comprising porous polymetamethyl acrylate having the air bubbles of 0.05 - 0.5g/cm<3> in its apparent density. In this instance, as it is less than 0.05g/cm<3> in its apparent density, the total strength of the foam and the cell strength of the foaming part falls extremely, and as it exceeds 0.5g/cm<3>, the foaming degree of a polymetamethyl acrylate core material drops necessarily. In the case wherein the containing rate of the aromatic polyamide fiber in the synthetic paper is less than 49wt.%, the bending strength of a molded composite material is small with a result that bending creases occur thereon.
