Abstract: An information processing system includes an information acquisition unit that acquires information on multiple bulletins to be posted in posting locations that are different from each other, a determination unit that determines, based on the information, an order of visitation according to which a worker posting bulletins visits each of the posting locations, and an instruction unit that provides an instruction to output printed matter that accounts for the order of visitation determined.

Abstract: An aircraft fuselage assembling jig is a horizontal-type jig on which an aircraft fuselage panel is placed in a laid-down state, and includes: a base with a plurality of frame indexes for positioning both ends of a plurality of aircraft fuselage frames; a plurality of header plates, each of which protrudes from the base to extend along the panel, the header plates being arranged in parallel in an axial direction of the panel; a plurality of electric cylinders radially provided on each plate, the electric cylinders moving respective receiving members in a radial direction of the panel, the receiving members contacting a skin included in the panel; and air lifting devices provided on the respective receiving members and that, when supplied with air pressure, lift the skin from receiving surfaces of the respective receiving members and support the aircraft fuselage panel such that the aircraft fuselage panel is slidable.

Abstract: An aircraft fuselage assembling jig includes: a base provided with a plurality of frame indexes for positioning both ends of a plurality of aircraft fuselage frames; a plurality of header plates, each of which protrudes from the base so as to extend along an aircraft fuselage panel, the header plates being arranged parallel to each other in an axial direction of the aircraft fuselage panel; and a plurality of electric cylinders radially provided on each of the plurality of header plates, the electric cylinders moving respective receiving members in a radial direction of the aircraft fuselage panel, the receiving members contacting a skin included in the aircraft fuselage panel.

Abstract: A component mounting system for mounting a component to a frame member by a fastener, and includes: a machining apparatus configured to machine a hole in each of the frame member and the component along a machining axis and fasten the frame member and the component together by the fastener; a positioning unit configured to perform positioning of a mounting position present on the frame member relative to the machining axis; a robot configured to transfer the component to the mounting position present on the frame member; and a detector including a camera and a sensor, the camera being provided on the machining axis and configured to capture an image of the component transferred to the mounting position, the sensor being configured to detect a tilt of the component transferred to the mounting position.

Abstract: A circular scratch inspection apparatus includes: a camera capturing an image of a workpiece surface around a hole; illumination device emitting light to the workpiece surface around the hole, the light being reflected on the workpiece surface is not directly incident on the camera; and image processor. The image processor: generates a second-derivative image by performing secondary differentiation on luminance values in an actual image obtained by the camera; generates a second-derivative curve for each of a plurality of ruler lines, extending radially from the hole center and are set in an inspection target region on the workpiece surface; counts a first reference number of times for each ruler line; calculates a first reference total number of times; and determines presence or absence of a circular scratch by using the first reference total number of times.
