Latest Patents

Kuwana's latest patents include an attitude control device and a drilling-direction control device. The attitude control device features a plurality of harmonic drive mechanisms of the hollow type, specifically first and second harmonic drive mechanisms. These mechanisms connect to first and second rotational members, which possess eccentric hollow portions that rotate eccentrically around the rotational axes of the harmonic drive mechanisms. A member to be driven extends through these eccentric hollow portions, allowing it to be supportedly contacted with their inner surfaces. During operation, the eccentric hollow portions rotate relative to each other, enabling the member to be driven to be oriented to a desired direction. This innovative design can also function as a drilling-direction control device, where a rotational drill shaft is supported by the inner surfaces of the eccentric hollow portions. By rotating these portions, the orientation of the drilling shaft can be adjusted from a vertical position.
