Patent number: 10780495Abstract: 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.Type: GrantFiled: September 10, 2015Date of Patent: September 22, 2020Assignee: Kabushiki Kaisha ToshibaInventors: Hideshi Nakano, Hiroshi Ohno, Morihiro Machida, Aya Watase

Patent number: 10646923Abstract: 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.Type: GrantFiled: March 24, 2016Date of Patent: May 12, 2020Assignee: Kabushiki Kaisha ToshibaInventors: Hideshi Nakano, Hiroshi Ohno, Aya Watase, Morihiro Machida, Kazunari Iwakawa, Shanying Pan

Patent number: 10259076Abstract: 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.Type: GrantFiled: September 17, 2014Date of Patent: April 16, 2019Assignee: Kabushiki Kaisha ToshibaInventors: Yusuke Suzuki, Hideshi Nakano, Hiroshi Ohno, Shanying Pan, Kotaro Kobayashi, Masayuki Tanaka, Morihiro Machida, Kazunari Iwakawa, Aya Watase

Patent number: 10040251Abstract: A layered object including a plurality of layers, the layered object includes a first part, and a second part. The first part includes a first face having a shape of protrusions and depressions. The first part constitutes a part of the layers. The second part is in contact with the first face. The second part includes a second face that fits with the protrusions and depressions and includes a third face opposite the second face. The second part includes another part of the layers. The third face includes a portion that has a higher degree of flatness than a degree of flatness of the protrusions and depressions.Type: GrantFiled: September 4, 2014Date of Patent: August 7, 2018Assignee: Kabushiki Kaisha ToshibaInventors: Takahiro Terada, Hiroshi Ohno, Aya Watase
