Title
(EN) CYLINDRICAL COIL AND CYLINDRICAL MICRO-MOTOR USING THE SAME
(FR) BOBINE CYLINDRIQUE ET MICROMOTEUR CYLINDRIQUE L’UTILISANT
(JA) 円筒状コイル及びそれを用いた円筒型マイクロモータ
Abstract
(EN) [PROBLEMS] To form a highly accurate and fine-structure coil pattern and to provide highly accurate cylindrical coil having an excellent mechanical accuracy such as circularity and deviation and a cylindrical micro motor using the cylindrical coil. [MEANS FOR SOLVING PROBLEMS] The cylindrical coil is formed with a cylindrical base surface on which insulation layers having a through hole and coil pattern layers formed by conductive nano particle paste are alternately printed by an ink jet nozzle array. The coil patterns overlaid are electrically connected to one another by the conductive nano particle paste filled in the through holes. The outermost layer is formed by the insulation layer having no through hole.
(FR) Les problèmes que l’invention se propose de résoudre consistent à former une spire de haute précision et structure fine pour obtenir une bobine cylindrique de haute précision aux excellentes propriétés de précision mécanique telles que circularité et déviation et un micromoteur cylindrique utilisant cette bobine. Les solutions trouvées dans le cadre de l’invention consistent à former la bobine cylindrique avec une surface de base cylindrique sur laquelle des couches d’isolation percées d’un trou et des couches de spires formées par une pâte conductrice de nanoparticules sont imprimées alternativement par une série de buses à jet d’encre. Les couches de spires supérieures sont connectées électriquement l’une à l’autre par la pâte conductrice de nanoparticules qui emplit les trous. La couche extérieure est une couche d’isolation sans trou.
(JA) 【課題】 高精度で微細なコイルパターンを形成し、且つ、真円度やフレ等、機械的精度の優れた高精度な円筒状コイル、及び、その円筒状コイルを用いた円筒型マイクロモータを提供する。 【解決手段】 円筒状基材表面に、インクジェットノズルアレイによって、スルーホールを備えた絶縁層と、導電性ナノ粒子ペーストによって形成されるコイルパターン層が、交互に複数層印刷され、積層されたコイルパターンは、前記スルーホールに印刷充填される導電性ナノ粒子ペーストによって電気的に層間接続され、最表層はスルーホールを形成しない絶縁層で構成されることを特徴とする円筒状コイルを形成する。
