Abstract: A gas-recycling device according to an embodiment includes a particle remover, a liquid remover, and a supplier. The particle remover brings a mist of liquid into contact with a gas which includes particles and is discharged from an apparatus, to remove the particles from the gas. The liquid remover removes the liquid from the gas having passed through the particle remover. The supplier supplies the gas to the apparatus.

Abstract: According to one embodiment, an electrospinning head includes a plurality of head units and a coupling structure, and the plurality of head units are coupled to one another through the coupling structure. Each head unit includes a unit main body and a nozzle. Inside the unit main body, a hollow storing a raw material liquid is formed along a longitudinal axis. The nozzle is formed of a conductive material and provided on an outer circumferential surface of the unit main body. The nozzle ejects the raw material liquid supplied through the hollow of the unit main body. The coupling structure connects the plurality of head units in a state where the hollows of the unit main bodies communicate with one another.

Abstract: A material feeder in an additive manufacturing apparatus according to one embodiment includes a feeding unit. The feeding unit includes a container capable of containing a powdery material, a first wall that is provided with a plurality of openings communicated with the container and that at least partially covers a region onto which the material is fed, and an opening-closing part capable of individually opening and closing the openings, the feeding unit forming a layer of the material on at least a part of the region by feeding the material inside the container onto the region from at least one of the openings that is opened by the opening-closing part.

Abstract: An additive manufacturing apparatus includes an operation unit, a first face, a mover, a supplier, and an irradiator. The operation unit includes a first part and a second part that cover a part of a supply region supplied with a powdery material and facing a first direction are aligned in a second direction, and includes a first opening extending between the first part and the second part in the first direction. The first face of the first part faces the second part, and is provided with a second opening. The mover moves the operation unit. The supply unit supplies an inert gas from the second opening to the first opening. The irradiator is spaced apart from the operation unit, and can emit an energy ray to the supply region through the first opening, and change a position with which the energy ray is irradiated.

Abstract: A device for manufacturing a layered object includes a container, a vibration unit, and an energy beam irradiation unit. The container includes a stage, a wall surrounding the stage, and a lid. The vibration unit vibrates raw material powder to planarize a face of the raw material powder supplied into the container. The energy beam irradiation unit irradiates part of the raw material powder with an energy beam to form part of the layered object. The lid presses the raw material powder when the vibration unit vibrates the raw material powder. A space is formed between the wall and the lid in the container when the lid is in contact with the raw material powder. The raw material powder is allowed to flow into the space.

Abstract: A mixer structure includes a helical fluid passage includes a first partition and a second partition. The first partition extends intersecting with a cross-sectional center line of the passage, and divides the helical passage into first sub-passages in parallel. The second partition is disposed downstream of the first partition, extends intersecting with the cross-sectional center line, and divides the helical passage into second sub-passages in parallel. A rear or downstream end of the first partition and a front or upstream end of the second partition intersect with each other or are at skew position.

Abstract: A nozzle includes a body. The body includes a supply port to which a liquid is supplied, a vent from which the liquid is discharged downward, and a flow channel that extends between the supply port and the vent. The flow channel includes: a storage including a first part through which the liquid flows downward to the vent, and a second part provided downstream of the first part, through which the liquid flows upward to the vent; and an exhaust capable of exhausting a gas upstream of the second part while the liquid is not discharged from the vent and is stored in the storage. The storage includes a third part connecting the first part and the second part. The exhaust includes a bypass channel that leads to parts upstream and downstream of the third part in the flow channel.
