  • Publication number: 20190299539
    Abstract: A method for performing thermo-fusion additive fabrication so as to allow the fusion with a member shaped by an arbitrary method, a method allowing a thermo-fusion additive fabrication object to be surely fused with another member, and a structure at least partially including the thermo-fusion additive fabrication object are provided. A method for performing thermo-fusion additive fabrication such that fusion can be performed on a shaped member even afterward includes: a step of providing a near infrared ray absorption material on the member by the thermo-fusion additive fabrication, the near infrared ray absorption material containing a near infrared ray absorption agent that absorbs a near infrared ray and a resin in which the near infrared ray absorption agent is dispersed; and a step of providing a thermoplastic resin material on the near infrared ray absorption material by the thermo-fusion additive fabrication.

  • Patent number: 10429480
    Abstract: A magnetic resonance imaging apparatus according to an embodiment includes a first acquiring unit, a second acquiring unit, and a combining unit. The first acquiring unit is configured to acquire data by executing a pulse sequence based on a first radio-frequency pulse transmission condition. The second acquiring unit is configured to acquire data by executing a pulse sequence based on a second radio-frequency pulse transmission condition that is different from the first radio-frequency pulse transmission condition. The combining unit is configured to perform a combining process either on the data acquired by the first acquiring unit and the data acquired by the second acquiring unit or on data obtained by reconstructing the data acquired by the first acquiring unit and data obtained by reconstructing the data acquired by the second acquiring unit.

  • Patent number: 9993949
    Abstract: Provided is a preform member bonding method, in a RTM process, for bonding a preform member and another member (a preform member or a hardened member) together with an adhesive. The preform member bonding method includes: beforehand obtaining data on a range of a level of progress in hardening of the adhesive which allows the adhesive to penetrate the preform member, and data on a range of the level of progress in the hardening of the adhesive which decreases bonding strength of the adhesive; and controlling the level of progress in the hardening of the adhesive by heat-treating the adhesive based on these data, before the preform member comes into contact with the adhesive.

  • Publication number: 20160347008
    Abstract: In a molding method using a VaRTM process in which a workpiece is impregnated with resin in a vacuum, the flow channel resistance or the thickness of which is not constant, an air-permeable sheet only permeable to gas and not permeable to resin (liquid) is arranged at the bottom surface of the workpiece to cover the total length of the workpiece in a direction in which the flow channel resistance or the thickness of the workpiece varies, to impregnate the resin.
