摘要： A layer forming apparatus includes a loading unit including a stage onto which powder is supplied, a rotator that flattens the powder on the stage to form a powder layer, and circuitry. The circuitry causes the rotator to move in a first direction parallel to a surface of the stage and rotate while contacting the powder on the stage to form the powder layer. Further, the circuitry causes the rotator to move in a second direction opposite to the first direction and rotate while contacting surplus powder not on the stage.

摘要： A fabrication apparatus includes a loading unit including a stage onto which powder is supplied, a rotator that rotates while moving to flatten the powder on the stage to form a powder layer, a solidification device that applies a fabrication liquid to the powder layer on the stage to solidify the powder layer to form a fabrication layer, and circuitry. The powder layer includes a first powder layer and a second powder layer. The circuitry causes the rotator to move and rotate to form the first powder layer having a cyclic uneven surface and form the second powder layer on the first powder layer. The second powder layer has an uneven surface that is in phase with the cyclic uneven surface.

摘要： A heat storage and release unit includes a reactant formed body for reacting with a reaction medium to store and release heat; a reaction vessel for accommodating the reactant formed body and exchanging heat with the reactant formed body; a reaction medium flow path structure, connected to the reaction vessel, for supplying the reaction medium to the reaction vessel or discharging the reaction medium from the reaction vessel. The reactant formed body includes a plate-like heat transfer plate that contacts the reaction vessel, heat transfer elements extending from a surface of the heat transfer plate at substantially right angles, and a reactant formed unit that encloses the heat transfer elements in such a way that the heat transfer elements are partially exposed from the reactant formed unit, and the reaction vessel can change form by a pressure difference between the outside and the inside of the reaction vessel.
