Various embodiments of the present disclosure provide a rotorcraft-assisted system and method for launching and retrieving a fixed-wing aircraft into and from free flight. The launch and retrieval system includes a modular multicopter, a storage and launch system, an anchor system, a flexible capture member, and an aircraft-landing structure. The multicopter is attachable to the fixed-wing aircraft to facilitate launching the fixed-wing aircraft into free, wing-borne flight. The storage and launch system is usable to store the multicopter (when disassembled) and to act as a launch mount for the fixed-wing aircraft by retaining the fixed-wing aircraft in a desired launch orientation. The anchor system is usable with the multicopter, the flexible capture member, and the aircraft-landing structure to retrieve the fixed-wing aircraft from free, wing-borne flight.

An image formation apparatus according to an embodiment may include: a print unit that forms an image on a medium; and a medium conveyance unit that conveys the medium to the print unit. The medium conveyance unit may include: a medium guide that is movable in a width direction of the medium perpendicular to a conveyance direction of the medium, to guide a width end of the medium; a guide position detector that detects a position of the medium guide in the width direction of the medium; and a medium end detector that is provided at the medium guide and detects whether there is the medium with the width end guided by the medium guide. The print unit may include a determination unit that determines a set state of the medium based on a detection result by the medium end detector.

At a printer that feeds a continuous paper unwound from a paper sheet supply unit in a sheet-shape to a printing head portion side via a damper portion, and then prints on a label of the continuous paper, the damper portion is constituted of an outer damper portion and an inner damper portion, which is disposed at a downstream side of feed of the outer damper portion.

A sheet conveyance apparatus includes a rotary member pair, a moving unit configured to move the rotary member pair in a width direction orthogonal to a sheet conveyance direction, an abutment member, an obliquely conveying portion, a detection portion, and a control unit. The control unit is configured to execute (1) a first mode of controlling the moving unit such that the rotary member pair is moved in the width direction based on a detection result of the detection portion before the sheet arrives at the obliquely conveying portion, and (2) a second mode of controlling the moving unit such that the rotary member pair is moved in a second direction regardless of a detection result of the detection portion in a state where the sheet is nipped by the rotary member pair and before the sheet arrives at the obliquely conveying portion.

An electrode used in a battery system, the electrode including a sheet made of a nonwoven fabric containing a plurality of carbon fibers. The sheet includes a first surface and a second surface that face each other in a direction along a thickness of the sheet, the plurality of carbon fibers include a first carbon fiber, the first carbon fiber includes at least one of a cut section facing the first surface and a cut section facing the second surface, a width of the sheet is less than or equal to 1000 mm, and a length of the sheet is less than or equal to 2000 mm.

A sheet conveyer to shift a sheet at one side of the sheet conveyer in a widthwise direction is provided. The sheet conveyer includes a pair of rollers, a regulative guide arranged at a position closer to the one side than the pair of rollers in the widthwise direction, a first guide arranged at a position upstream from the pair of rollers with regard to a conveying direction to contact a first area on a first face of the sheet at a position closer to the one side in the widthwise direction than a widthwise center of the sheet, and a second guide arranged at a position upstream from the pair of rollers with regard to the conveying direction to contact a second area on a second face of the sheet. The second guide partly overlaps the first guide in a direction of height.

An image reading apparatus includes a stacking portion, a feeding unit, a reading unit, and a discharge portion provided below the stacking portion. The feeding unit feeds a sheet stacked on the stacking portion in a feeding direction. The reading unit reads an image on the fed sheet and the discharge portion discharges the read sheet. The stacking portion includes first and second support surfaces that support the sheet and first and second regulating units to regulate a position of the sheet in a widthwise direction using two opposing ends of the sheet. The second support surface is retractable from a predetermined section above the discharge portion. The first support surface includes a downstream support portion that supports the sheet on a downstream side of the predetermined section in the feeding direction. A part of the second regulating surface is positioned on the downstream support portion.

At a printer that feeds a continuous paper unwound from a paper sheet supply unit in a sheet-shape to a printing head portion side via a damper portion, and then prints on a label of the continuous paper, the damper portion is constituted of an outer damper portion and an inner damper portion, which is disposed at a downstream side of feed of the outer damper portion.

An image forming apparatus configured to form images on a first surface and a second surface of a sheet includes an apparatus body, an image forming unit, a feed tray, and a return unit configured to return the sheet having an image formed on the first surface of the sheet toward the image forming unit. The return unit includes a first guide, a second guide, and an adjuster. The first guide is detachably attached to the second guide and includes a first roller and a positioned portion. The second guide is positioned in the apparatus body and includes a second roller facing the first roller, and a positioning portion configured to contact the positioned portion of the first guide, thereby positioning the first guide relative to the second guide. The adjuster is configured to adjust an orientation of the second guide relative to the apparatus body.
