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: In a main bearing replacement method for a wind turbine power generation facility including a nacelle, a rotor head rotatably supported by the nacelle, a drive shaft to which rotation of the rotor head is transmitted, a main bearing disposed between the rotor head and the nacelle, and a coupling connecting the rotor head and the drive shaft on a radially inner side of the main bearing, the wind turbine power generation facility includes a main bearing sleeve fitted and fixed to an inner ring of the main bearing and mounted with the rotor head, and the main bearing is replaced at least while the main bearing sleeve is fitted and fixed to the inner ring of the main bearing.

Abstract: A method for lifting/lowering a long object in a wind power generating apparatus which includes a rotatably disposed rotor head, the rotor head having an openable and closable opening which causes an interior space of the rotor head and an exterior of the rotor head to communicate with each other, the interior space being disposed with a long jig for hanging the long object, the method includes a horizontal movement step of moving the long object in a horizontal attitude along a horizontal direction to be close to the opening or to be away from the opening in the interior space, an attitude change step of changing an attitude of the long object between the horizontal attitude and a vertical attitude vertically above the opening in the interior space, and a lifting/lowering step of lifting/lowering the long object in the vertical attitude while hanging the long object from the jig.
