Latest Patents
One of Tanaka's latest patents is the Generator Hub Adapter. This device is designed for use on a bicycle generator hub and includes a mounting portion and a contact terminal. The mounting portion is specifically dimensioned to contact the axial outer face of a nut member of the generator hub. It is electrically connectable to the nut member and can be easily mounted on a hub axle supporting the generator hub. The contact terminal is formed integrally with the mounting portion, providing a simple means for completing an electrical circuit without requiring modifications to the bicycle frame or the generator hub.
Another notable invention is the Bicycle Generator Hub. This hub is mounted to the front fork of a bicycle and consists of a hub shaft, a hub shell, bearings, a generator mechanism, and first and second magnetic flux recirculation members. The hub shaft is non-rotatably mounted to the front fork, while the hub shell is disposed around the surface of the hub shaft. The bearings allow the hub shell to rotate relative to the hub shaft. The generator mechanism features a coil mounted to the hub shaft and a magnet unit that generates electric power through the rotation of the hub shell. The magnetic flux recirculation members help return any leaked magnetic flux to the coil, enhancing the efficiency of the generator.
