Latest Patents

Akiyama's latest patents include a tachogenerator featuring a magnetoresistance stator coil. This innovative tachogenerator incorporates a magnetoresistance film coil formed on a stator surface along a circular path concentric with the rotor axis. The coil is designed with a spatially periodic structure, consisting of multiple spaced-apart lateral components that are series connected with longitudinal components. The stator surface is positioned opposite to a rotor surface that has multiple equiangularly spaced magnetic pole faces with alternately opposite polarities. The current passed through the coil generates voltage variations, while undesirable small voltage variations resulting from manufacturing tolerances are averaged to zero at the coil output terminals.

Another notable patent is a coil assembly that features stacked spiral pattern layers and a method of making it. This coil assembly comprises several conductive spiral pattern layers piled up via insulating layers on a wafer. The electrical connection between the spiral patterns is established through a conductive member, which is a portion of the upper spiral pattern layer. This member is filled in a through-hole made in the insulating layer, allowing the spiral patterns to connect in series and develop a high voltage when the coil assembly is moved in a magnetic field.
