Latest Patents

Shirokawa's latest patents include an antenna apparatus designed for satellite communication. This apparatus features an antenna that can rotate in both azimuth and elevation angles, allowing for miniaturization without the need for a slip ring to maintain electrical connections between stationary and movable parts. The design incorporates a motor that rotates a rotary member, which in turn rotates the antenna about the azimuth axis. Additionally, the relative rotation between the rotary member and a relative rotary shaft enables the antenna to rotate about the elevation angle axis through a bevel gear mechanism. Another notable patent is the waveguide rotary coupler, which utilizes an AC power source to induce electromotive force in a secondary coil located in a movable part. This induced AC electromotive force is then converted into DC power for use in a drive control section.
