Abstract: A method of manufacturing produces an assembled product where a ring-shaped seal is attached to a channel in an inner circumferential surface of a ring-shaped component. The method includes: a holding step that moves an engaged portion of the seal inwardly in a radial direction using a deformation member, while restricting movement of the seal in a direction parallel to an inner circumferential wall of the channel, to cause deformation so that the outer diameter of part of the seal aside from the engaged portion becomes smaller than the channel inner circumferential diameter; and an attachment step that attaches the seal to the channel by releasing the seal to restore the seal from the deformation. The attachment step includes releasing the seal by releasing engagement by the deformation member and moving the seal body inside the channel while pressing out the seal body from inside.

Abstract: A method of manufacturing a component and a component manufacturing apparatus to attach an attached part in a predetermined posture to a ring-shaped channel formed in an outer circumference of a component main body. While being held by holding portions, a ring-shaped seal body is placed in contact with a tapered portion and has its diameter expanded to at least the outer diameter of the component main body. The seal body elastically deforms from the expanded-diameter state so that its diameter reduces and is attached to the attachment channel in the outer circumferential surface of the component main body while being guided by the holding portions.

Abstract: A substance detection method includes the steps of: heating a sample adhered to a substance with a temperature at which the substance is readily vaporized to vapor the substance; sucking air and feeding the sucked air in a direction different from a direction along which the substance is vaporized; negatively ionizing the vapor sucked with the air; and detecting the substance adhered to the sample by analyzing the negative ion.
