Abstract: An output content generation device, includes: a first calculation unit that calculates a size, in a display region of a display device, of each of pieces of information to be displayed in the display region; a determination unit that determines whether or not the pieces of information are arrangeable in the display region, based on the size of each of the pieces of information and a size of the display region; and a generation unit that allocates the pieces of information in a plurality of screens accommodated in the display region in a distributed manner, and generates output content of the pieces of information, when the pieces of information are not arrangeable in the display region, thereby enabling information to be legibly viewable.

Abstract: A mammography apparatus includes: an imaging table; a radiation source; a compression plate that compresses the breast and is movable between the radiation source and the imaging table; a projector that includes a display displaying an image including first information projected onto a first surface facing the radiation source on the imaging table and second information projected onto a second surface facing the radiation source on the compression plate, and a projection optical system, in which a focus of the projection optical system is adjusted in accordance with a projection distance to the first surface; and a processor that is configured to control the display and change at least one of a display size or a display position of the second information in the image on an image display surface of the display in accordance with movement of the compression plate having the second surface independently of the first information.

Abstract: A mammography apparatus includes an imaging table; a radiation source; a stand; the compression plate including a bottom plate that compresses the breast and side plates provided on at least two locations of a subject side and a stand side of the bottom plate; and a projector that projects an image toward the compression plate and the imaging table, in which in a case where an intersection between an imaginary plane formed by extending the inner wall surface toward the projector and an imaginary horizontal line crossing the projector in a horizontal direction is defined as an imaginary intersection, an optical element closest to the compression plate on an optical path directed from the projector to the compression plate is located on the subject side with respect to the imaginary intersection.

Abstract: A mammography apparatus includes: an arm; a first cooling fan that is disposed on a stand side with respect to the radiation source in the arm, sucks air from an outside of the arm, and discharges air that has cooled the radiation source from a first exhaust port provided on the stand side with respect to the radiation source; a projector that is disposed in the arm; a second cooling fan that is disposed between the projector and the first exhaust port in the arm, sucks a part of air directed from the first cooling fan to the first exhaust port, blows the sucked air toward the projector to cool the projector, and has a flow rate smaller than that of the first cooling fan; and a second exhaust port that is provided separately from the first exhaust port and through which air that has cooled the projector is discharged.

Abstract: A mammography apparatus includes an arm; and a stand, the arm is provided with a drive mechanism including a motor that rotationally drives the radiation source holding portion, and a first restriction mechanism that restricts rotation of the imaging table about the axis of the support shaft, the first restriction mechanism is disposed on a side opposite to a radiation source with respect to the support shaft, and the drive mechanism is disposed on a radiation source side with respect to the first restriction mechanism and in a case where a center line of the arm extending in a direction connecting the radiation source and a center of the support shaft is assumed, the drive mechanism is disposed so as to intersect the center line.

Abstract: The object of the present invention is to provide an aqueous coating composition which exhibits a small viscosity change and can form a coating film having a superior coating film appearance even when the amount of the solvent contained in the aqueous coating composition is reduced due to changes in the coating environment.

Abstract: An aqueous coating composition comprising an acrylic resin dispersion (A) having a core/shell structure and a melamine resin (B) comprising a hydrophobic melamine resin, wherein the acrylic resin dispersion (A) is a dispersion of a solution-polymerization product of a core part preparation monomer (a-1) and a shell part preparation monomer (a-2), wherein the shell part preparation monomer (a-2) comprises an acid group-containing polymerizable monomer. The aqueous coating composition exhibits a small viscosity change and can form a coating film having a superior coating film appearance, even when the amount of the solvent contained in the aqueous coating composition is reduced due to changes in the coating environment.
