Latest Patents

Koji Arata holds a patent for a groundbreaking "Drive control apparatus for an electrically-driven type". This invention encompasses a sophisticated control circuit linked to a power supply, which manages the operation of a motor capable of rotating in both normal and reverse directions. The apparatus features a multi-threaded worm mechanism on the motor's output shaft, which effectively engages a worm wheel. This interaction transmits rotational force to a drive gear, facilitating the movement of a longitudinal drive rope that extends and retracts an antenna element.

The design also incorporates mechanical stoppers to halt the antenna's movements upon reaching its limits, along with an integral shock absorber primarily composed of elastic materials to mitigate impact forces during operation. Additionally, the invention includes switching mechanisms that intelligently cut off power to the motor to prevent damage when the shock absorber's elastic deformation ceases.
