Description
最初に本発明の実施態様を列記して説明する。
以下、本発明の実施の形態について図に基づいて説明する。なお、以下の図面において、同一または相当する部分には同一の参照番号を付し、その説明は繰り返さない。
(超電導線材の構成)
図1は、本発明の実施の形態1に係る超電導線材の構成を示す断面模式図である。図1は、実施の形態1に係る超電導線材10の延在する方向に交差する方向に切断した断面を示している。このため、紙面に交差する方向が超電導線材の長手方向であり、超電導材料層5の超電導電流は紙面に交差する方向に沿って流れるものとする。また、図1および以降の断面模式図においては、図を見やすくするために矩形状の断面における上下方向(以下、「厚み方向」とも称する)と左右方向(以下、「幅方向」とも称する)との長さの差を小さくしているが、実際は当該断面の厚み方向の長さは幅方向の長さに比べて十分に小さい。
次に、図3〜図8を参照して、実施の形態1に係る超電導線材の製造方法について説明する。以下では、30mm幅に作製された積層体20から4mm幅に細線加工された積層体20を用いて超電導線材10を製造する方法を例に挙げ、本実施の形態を具体的に説明する。
図13は、本発明の実施の形態2に係る超電導線材の構成を示す断面模式図である。図13は、実施の形態2に係る超電導線材10の延在する方向に交差する方向に切断した断面を示している。
図14は、本発明の実施の形態3に係る超電導線材の構成を示す断面模式図である。図14は、実施の形態3に係る超電導線材の延在する方向に交差する方向に切断した断面を示している。
図18は、本発明の実施の形態4に係る超電導線材の構成を示す断面模式図である。図18は、実施の形態4に係る超電導線材の延在する方向に交差する方向に切断した断面を示している。
図20は、本発明の実施の形態5に係る超電導線材の構成を示す断面模式図である。図20は、実施の形態5に係る超電導線材の延在する方向に交差する方向に切断した断面を示している。
