Patent number: 7794643Abstract: A method of molding an object with a mold having a transfer face includes the steps of filling, separating, re-melting, re-contacting, cooling, and removing. The filling step fills a thermoplastic material, having a temperature greater than a softening temperature of the thermoplastic material, into a cavity space in the mold having a temperature smaller than the softening temperature of the thermoplastic material. The thermoplastic material comes in contact with the transfer face and is cooled. The separating step separates the transfer face from the thermoplastic material to form a heat-insulating layer between the thermoplastic material and transfer face. The re-melting step re-melts the thermoplastic material with heat energy retained inside the thermoplastic material. The re-contacting step re-contacts the re-melted thermoplastic material to the transfer face. The cooling step cools the thermoplastic material to a temperature smaller than the softening temperature of the thermoplastic material.Type: GrantFiled: March 23, 2007Date of Patent: September 14, 2010Assignee: Ricoh Company, Ltd.Inventors: Jun Watanabe, Yasuo Yamanaka, Kiyotaka Sawada, Keiji Ueda, Yasunori Sugimoto

Patent number: 7785436Abstract: A laminating apparatus and a laminating method for finely finishing laminate processing without performing edge processing after the laminate processing is performed to a recording medium. A laminate material having a size larger than that of the recording medium is placed to cover the recording medium, bonded with heat and pressure, and a laminate layer protruding from the recording medium is transferred to a means to be transferred to, which is arranged on an opposite plane side to a recording plane of the recording medium. When the means to be transferred to is arranged apart on the opposite plane side to the recording medium, the laminate layer is pulled into the opposite plane side to the recording medium. As a result, an edge of the laminate layer formed on the recording plane of the recording medium becomes fine, matching with an edge of the recording medium.Type: GrantFiled: March 30, 2005Date of Patent: August 31, 2010Assignee: Noritsu Koki Co., Ltd.Inventors: Yoshihiko Nakashima, Junichi Yamamoto, Yasuto Kimura, Hironori Masutani, Nobuaki Nakaoka
