Latest Patents

One of Okada's latest patents is for a coil unit and electronic instrument. This innovative coil unit features a planar coil with a transmission side and a non-transmission side. It includes a magnetic sheet positioned over the non-transmission side of the planar coil, along with a heat sink/magnetic shield plate. This plate is stacked on the side of the magnetic sheet that does not face the planar coil. Its purpose is to dissipate heat generated by the planar coil while also shielding magnetism by absorbing magnetic flux that the magnetic sheet does not capture. Notably, the heat sink/magnetic shield plate has a thickness greater than that of the magnetic sheet. Another patent involves a coil unit and electronic apparatus utilizing similar technology, which includes a coil with a coil wire, a magnetic substance for receiving magnetic force lines, a first substrate, and a temperature detection element.
