发明名称 NONCONTACT MEMORY CARD AND ELECTROMAGNETIC COUPLING DEVICE MOUNTABLE ON SAME
摘要 <p>PURPOSE: To provide the electromagnetic coupling connector equipped with a power carrier coil which is small-sized and high in the transmission efficiency of electric power. CONSTITUTION: Magnetic cores 3j1 , 3j2 , and 3j3 of the same size in the same shape which are wound with coils 2j1 , 2j2 , and 2j3 respectively are connected across adhesive layers 31a and 31b to form the power carrier coil 30. The winding directions of the coils or the application directions of exciting currents are adjusted to drive the adjacent coils in mutually opposite directions. The magnetic cores may be formed of one magnetic body having plural winding parts formed at equal intervals.</p>
