Patent number: 8070468Abstract: A sheet film forming roll includes a center rotary shaft. Fixed end plates are disposed in two locations which are away from each other in an axial direction of the center rotary shaft, respectively. An external cylinder is made of a metal thin film. Two ends of the external cylinder are rotatably supported by the fixed end plates, respectively. Multiple rolling rubber rolls have ends which are rotatably supported by the respective fixed end plates. The rolling rubber rolls are in sliding contact with an outer peripheral surface of the center rotary shaft, and in sliding contact with an inner peripheral surface of the external cylinder. The rolling rubber rolls divide an annular space between the external cylinder and the center rotary shaft into multiple heating medium chambers arranged in a circumferential direction of the sheet film forming roll. A heating medium is configured to be filled in each of the multiple heating medium chambers.Type: GrantFiled: May 28, 2009Date of Patent: December 6, 2011Assignee: Toshiba Kikai Kabushiki KaishaInventors: Takayoshi Sano, Takashi Hirose, Tatsuaki Miyazaki

Patent number: 8043538Abstract: In a mold temperature control circuit of an injection molding device, such a molding cycle is repeated that, prior to injection of a resin, a heating-use medium is returned to molds and heated to a temperature suitable for resin injection, after injection of the resin, the heating-use medium is switched to a cooling-use medium, thereby the cooling-use medium is returned to the molds and cooling is conducted to give a temperature equal to or lower than a temperature at which the resin is solidified.Type: GrantFiled: June 29, 2009Date of Patent: October 25, 2011Assignee: Mitsubishi Heavy Industries Plastic Technology Co., Ltd.Inventors: Michitaka Hattori, Satoshi Imaeda, Toshihiko Kariya

Patent number: 8043537Abstract: There are provided an injection molding system, a computer program, a method of injection molding, and an injection molding machine capable of performing precise temperature control of a mold even when there is a delay in temperature increase of the mold in heat supply with a heating medium. The temperature control is performed so that temperatures of a fixed mold and a movable mold are maintained between an upper limit TU and a lower limit TL of a predetermined temperature range after start of injection of resin during an injection molding cycle. The temperature control of the fixed mold and the movable mold is performed only by switching ON/OFF supply of the heating medium, and cooling with a cooling medium is not performed.Type: GrantFiled: October 31, 2007Date of Patent: October 25, 2011Assignee: Mitsubishi Heavy Industries Plastics Technology Co., Ltd.Inventors: Yoshio Shikase, Michitaka Hattori, Shigeru Nozaki, Satoshi Imaeda, Toshihiko Kariya

Patent number: 8038430Abstract: A method of coating metal wire with extrudate using an extrusion system. The method includes the steps of advancing the metal wire through an extrusion die of the extrusion system and extruding molten extrudate over the metal wire as the metal wire is advanced through the extrusion die. Image data is generated, using one or several electronic cameras, concurrently with the advancing, and extruding to provide visual feedback indicative of the concentricity or non-concentricity of extrudate surrounding the metal wire as the metal wire exits the extrusion die.Type: GrantFiled: October 13, 2009Date of Patent: October 18, 2011Assignee: Advanced Neuromodulation Systems, Inc.Inventors: John W. Swanson, Lucien M. Rucker

Publication number: 20110204535Abstract: A disk substrate molding apparatus has a disk substrate molding die and a temperature controller. The disk substrate molding die includes a stamper, a first die including a mirror member to which the stamper comes in contact, and a second die including a molding surface which forms a disk-shaped cavity between the molding surface and the stamper. The second die includes a protruding part which protrudes toward the stamper at an outer circumferential part of the molding surface. The temperature controller controls temperature of the second die so that the protruding part exhibits a higher temperature in comparison to a region further toward the inner circumferential side than the protruding part, and controls temperature of the first die so that a region opposite to the protruding part exhibits a lower temperature in comparison to the protruding part in the mirror member.Type: ApplicationFiled: September 1, 2010Publication date: August 25, 2011Inventor: Kazuo Inoue
