Description
1つ又は複数の軟磁性部材が環状体(トロイド)として巻き付けられ、
巻き付けられた環状体が一箇所で切断されて展開され、縦長のアンテナコアに再形成される。
軟磁性部材に磁界内での熱処理によってその軟磁性特性(例えば、透磁率、B−Hループの形状、保持力、磁気ひずみ等)が調整されるステップである。
図9はアンテナコアの製造方法を示すものである。この場合、開放フレームとして形成された型枠17内にまずテープ1が装着される。しかし、このフレーム自体、薄いフレームを持つものとすることができる。その上に巻線18が施される。巻線18は例えばフレーム17の外側角に設けられる刻み目の中に巻き込まれる。このようにして形成された中間製品が次のステップで接着され、又はモールドされ、又はテープを巻き付けられ、その後、シュリンクチューブ19が被せられてシュリンキングが施される。図9の最下部に、シュリンキングが施された形のシュリンクチューブ19が示されている。そこには、アンテナコアの端部20,21が押圧工具による成形によって平らにされ、幅広に押圧されている。それによってシュリンクチューブも端部でアンテナコアの内部と密に結合することができる。
