Abstract: A base supporting an offshore wind power generator includes a fender portion composed of a pair of cylindrically shaped first fender portion and second fender portion for cushioning an impact when a ship touches the fender portion, and rung portions extending horizontally from the fender portion toward the base and composed of first rung portions and second rung portions installed at predetermined intervals in the vertical direction. A worker on board the ship can safely transfer to the adjacent rung portions when the hull of the ship kept touching the fender portion.

Abstract: An information processing apparatus includes a processor configured to: detect a specific noncontact operation performed by a user on an operation surface; and display, if the specific noncontact operation is detected, an operation object for achieving a gesture operation based on movement of the user with respect to the operation surface.

Abstract: A propeller fan includes a blade configured to rotate around a predetermined rotation axis, and a ring connected to a blade end of the blade. The blade includes a curved portion on a side on which the blade end is located. The curved portion has, in a rotational radial direction of the blade, a cross-sectional shape projecting in a convex manner toward a side on which a pressure surface is located. In the curved portion, when a height from a position of a blade root on a camber line in a direction along the predetermined rotation axis is an axial-direction height and a position at which the axial-direction height becomes maximum in the rotational radial direction is a maximum curve position, the axial-direction height at the maximum curve position is maximum on a side on which a trailing edge of the blade is located.

Abstract: A propeller fan includes a hub rotatable about an axis, and a plurality of blades extending radially outward from an outer peripheral surface of the hub. A ring surrounds the plurality of blades and is connected to each blade tip. A maximum camber location is on a camber line where a distance from a chord line to the camber line in an arc-shaped cross section of each blade about the axis is maximum. An axial height is from a trailing edge to the camber line in a direction along the axis. Each blade has a first portion provided inside in the radial direction of rotation and whose axial height at the maximum camber location is substantially constant, and a second portion provided outside in the radial direction of rotation and whose axial height at the maximum camber location increases toward the blade tip.

Abstract: An information processing apparatus includes a processor configured to: in a case where a selection function selected by a user does not correspond to an operation address that is an address associated with an operation unit operated by the user, cause a display unit to display a screen showing an address corresponding to a relationship between a registered address, which is an address registered in a contact address associated with the operation address, and the selection function.

Abstract: An information processing device includes a processor configured to issue an instruction to an image forming device. The processor is configured to: in a case where an interruption instruction is received, issue an instruction for a processing mode of the image forming device to be transitioned from a normal mode in which jobs are executed in an order in which the jobs are received, to an interruption mode in which a job that is being executed is suspended and an interruption job is executed first; and, after completion of the interruption job, issue an instruction for the processing mode to be transitioned from the interruption mode to the normal mode, in accordance with a cancellation method in which the interruption mode is canceled, predicted from information representing a state of the image forming device.

Abstract: An information processing device includes a process execution unit that executes a process, a generation unit that, in response to a login request from a user, generates login session information that becomes invalid if the user logs out, and a control unit. If user identification information assigned to a user who specified the execution of the process is unique user identification information that is unique to the user, the control unit controls a user operation on the process with the unique user identification information. If user identification information assigned to a user who specified the execution of the process is shared user identification information that is shared among multiple users, the control unit controls a user operation on the process with the login session information.
