Abstract: A laminating system sandwiches a sheet medium in a two-ply sheet in which two sheets are overlapped and partially joined together and applies heat and pressure to bond the two-ply sheet. The laminating system includes a sheet separating device, a laminate-fixing device, and a conveyor. The sheet separating device separates the two sheets of the two-ply sheet and sandwiches the sheet medium between the two sheets. The laminate-fixing device heats and presses the two-ply sheet sandwiching the sheet medium. The conveyor conveys the two-ply sheet sandwiching the sheet medium from the sheet separating device to the laminate-fixing device. The laminate-fixing device is disposed above the sheet separating device.

Abstract: A method of manufacturing optical elements in which a precision-processed pressing mold is used and the molding surface thereof is transferred to a heat-softened preformed molding material to form an optically functional surface. In the method, post processing for centering and edging are conducted following precision pressing to determine the center axis of an optical element and/or to form on the periphery of the optical element a portion for mounting on some other component. The preformed molding material has a weight within a range of 110 to 155% of a weight of the optical element when the optical element has a biconvex or convex meniscus shape. The preformed material has a weight within range of 180 to 240% of a weight of the optical element when the optical element has a biconcave or concave meniscus shape.

Abstract: A sheet laminator includes a fuser pressure member, a conveyor, and a guide. The fuser pressure member thermally fixes a two-ply sheet and a sheet medium inserted between two sheets of the two-ply sheet. The conveyor conveys the two-ply sheet toward the fuser pressure member in a sheet conveyance direction. The guide guides the two-ply sheet in a sheet conveyance passage between the conveyor and the fuser pressure member. At least one of the fuser pressure member or the conveyor is operable to guide the two-ply sheet outside the sheet conveyance passage in response to an occurrence of an abnormal stop of the sheet laminator.

Abstract: An image forming apparatus includes an intermediate transfer body, a plurality of image bearers, a plurality of developing devices, a plurality of primary transfer devices, a secondary transfer device, and a cleaner. The plurality of image bearers is disposed side by side along the intermediate transfer body In a refreshing mode, the plurality of developing devices form toner images on the plurality of image bearers during a non-image-formation period and the cleaner cleans a surface of the intermediate transfer body. In the refreshing mode, a toner image formed on one image bearer of the plurality of image bearers, which differs from a most downstream image bearer of the plurality of image bearers in a direction of conveyance of the intermediate transfer body, reaches the cleaner first of the toner images formed on the plurality of image bearers.

Abstract: A lamination processing system includes a sheet separation device, a lamination fixing device, and a conveyor. The sheet separation device separates a two-ply sheet to insert a sheet medium between two sheets of the two-ply sheet to form an enclosed two-ply sheet. The lamination fixing device includes an inlet port and a heater. The conveyor conveys the enclosed two-ply sheet from the sheet separation device to the lamination fixing device in a conveyance direction. The conveyor includes a conveyance passage and a guide. The conveyance passage guides the enclosed two-ply sheet from the sheet separation device toward the lamination fixing device. The guide guides the enclosed two-ply sheet to the inlet port. The guide forms a space accommodatable a deflected part of the enclosed two-ply sheet formed by a difference in a conveyance speed of the enclosed two-ply sheet between the sheet separation device and the lamination fixing device.

Abstract: A sheet laminator includes a thermal fixing roller pair, a first heater, a second heater, multiple temperature detectors, and a driver. The thermal fixing roller pair includes a first thermal fixing roller and a second thermal fixing roller facing the first thermal fixing roller. The thermal fixing roller pair thermally fixes and conveys a two-ply sheet and a sheet medium nipped between two sheets of the two-ply sheet. The first heater heats the first thermal fixing roller. The second heater heats the second thermal fixing roller. The multiple temperature detectors are at different positions along an axial direction of the thermal fixing roller pair. The multiple temperature detectors detect a surface temperature of the thermal fixing roller pair. The driver drives the thermal fixing roller pair.
