Publication number: 20110139572Abstract: The present invention provides a method for manufacturing a steel plate-shaped component which can increase the yield and the working efficiency. When a steel plate-shaped component (1) such as a pole parking is manufactured, a steel disk-shaped initial material (10) is vertically placed in a cavity (41) of a dice (40) of a cold forging die so that the thickness direction of the initial material (10) is perpendicular to a pressing direction. The initial material (10) is pressed through cold forging against the peripheral side portion (11) by a punch (42) while the initial thickness of the initial material (10) is maintained substantially as it is, whereby an approximate component (20) approximating the plate-shaped component (1) is obtained. Subsequently, a margin portion (25) of the approximate component (20) is removed, whereby a half-finished product (30) is obtained.Type: ApplicationFiled: November 4, 2010Publication date: June 16, 2011Applicants: TOSHIMA MANUFACTURING CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hitoshi Nomasa, Hiroki Uba, Yoshinori Morita, Ryuji Ibaraki, Koichi Kondo, Masahiro Kojima, Fuminori Ashikawa, Tsugio Saito

Patent number: 5804678Abstract: In a gas phase olefin polymerization, an olefin is continuously fed to a fluid bed reactor in which a metallocene catalyst is present. At least one compound selected from water, alcohols and ketones is added in a specified amount simultaneously with the feeding of the olefin. Thus, an olefin polymer having a satisfactory drop second count index as defined by the below indicated formula is produced: ##EQU1## wherein t.sub.0 and t respectively represent a flow time measured in the flow test according to ASTM D-1775 of the olefin polymer obtained when none of the water, alcohols and ketones is incorporated in the reactor, and when at least one compound of water, alcohols and ketones is incorporated in the reactor. The flowability of the polymer formed in the reactor is excellent, so that blocking, bridging and the like do not occur during the gas phase polymerization. Thus, it is feasible to stably produce a (co)polymer having excellent particle properties in high yield for a prolonged period of time.Type: GrantFiled: July 12, 1994Date of Patent: September 8, 1998Assignee: Mitsui Petrochemical Industries, Ltd.Inventors: Yoshinori Morita, Hiroshi Nishikawa, Yutaka Haneda, Satoru Ohtani, Kenji Doi
