Title: Extrusion of metal junction plastic molded article
Inventor: OCHIUMI MASAHIDE
IPC: B29C61/00
Filed: 1979-12-19
Abstract: PURPOSE: To prepare the firmly bonded, titled molded article by a method wherein after the surface of a metallic body is covered with a copolymer (graft) composed of olefin and an unsaturated carboxylic acid derivative, it is fixed in a metallic  mold and polyolefin is extruded.  
     CONSTITUTION: A metallic body (example: aluminum foil, etc.) is covered with olefin (example: ethylene, propylene, etc.) and unsaturated carboxylic acid or its derivatives [example: (meta)acrylic acid, maleic anhydride, etc.] and this is inserted into a metallic mold and then, fixed on the metallic mold wall and thereafter, polyolefin is extruded. The heat possessed by the polyolefin extruded in a metallic mold melts partially the surface of a denatured polyolefin of a laminate of the previously inserted metal and the denatured polyolefin, thus, polyolefin and the denatured polyolefin are firmly bonded. As mentioned in the above, a laminated molding firmly bonded with polyolefin and a metal is prepared efficiently through the mediation of a denatured polyolefin.

Title: Field-effect optical modulation element
Inventor: GOTO HIDEKI
IPC: G02F1/025
Filed: 1995-06-30
Abstract: PURPOSE: To reduce the electric power consumption of a field-effect optical modulation element and to enhance its efficiency. CONSTITUTION: A flat first semiconductor of a rectangular parallelepiped shape, etc., is used as an active region 1 and the active region 1 is formed into a flat quantum box structure enclosing a second semiconductor 2. Electrodes 3 are so arranged that the impression of an electric field in a direction X where the quantum confinement exclusive of the shortest size is weak is made possible. The three directions are closed and, therefore, if the electric field is impressed in the direction where the quantum confinement is weak, the electrons and holes constituting exciton can move largely in direction reverse from each other in the state that the exciton exists stably. The utilization of a large change in the exciton energy and a change in vibrator intensity is made possible with the lower electric field than heretofore.  Then, the reduced electric consumption and enhanced efficiency of the fieldeffect optical modulation element are embodied.
