本研究的目的是研制一种从口腔液体中密封的小型杯状磁附着体。该磁性装置在磁铁、磁轭和保持器之间形成闭合电路。将一块3.2 mm×1.4 mm的SmCO5磁体放入447J1不锈钢的杯形磁轭中，并用447J1不锈钢圆盘磁轭和316L不锈钢环覆盖。为了保护磁铁不受腐蚀，连接用激光焊接进行了密封。用有限元方法计算出了最优尺寸。对磁性附着体的性能进行了研究。结果，研制出直径4.4 mm、高度2.1 mm的磁体装置。守门员触球时的分离保留率平均为341gf。
The purpose of this study was to develop a small cup type yoke magnetic attachment sealed from oral fluid. The magnetic device forms a closed circuit between the magnet, yokes, and keeper. A 3.2 mm phi x 1.4 mm SmCO5 magnet was put into a cup yoke of 447J1 stainless steel and covered by 447J1 stainless steel disk yoke with a 316L stainless steel ring. To protect the magnet from corrosion, the connection was sealed by laser welding. The optimum dimensions were figured out by a finite element method. The performance of the magnetic attachment was investigated. As a result, a magnet device 4.4 mm in diameter and 2.1 mm in height was developed. The breakaway retention when the keeper touched it was 341 gf on average.
