| Outline of Final Research Achievements |
We are conducting basic research for the practical application of non-contact magnetic bearings that integrate superconducting bulk materials that can be used in the liquid nitrogen temperature range. This time, we conducted research on a bonding method that simultaneously considers mechanical and magnetic bonding at the time of integration, which is one of the most difficult technical problems among the goals.
As a result of our research, we clarified the optimization process and the investigation method for the investigation of the single bulk shape up to the incorporation of the magnetic bearing. Based on the collected bulk data and the results of integrated bulk data constructed using fixing jigs, the process of reaching the ideal model was clarified.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の成果である、集積型超伝導バルクの電磁気的接合方法の検討によって、バルクを応用した回転機や軸受等への組込み自由度が飛躍的に向上させることができたと考えられる．
これらにより，設計的に制約の多い超伝導機器応用のみならず，それ以外の分野でもその応用範囲が広がることとなり、様々な分野への応用が期待できる．そして、それらの実用化によって社会全般に貢献することと考えられる．
