Latest Patents

Watanabe holds 2 patents that showcase his innovative approach. His first patent involves an encoder designed to provide calibrated measurement capability of rotation. This invention features a scale with a regular arrangement of optically or magnetically different response characteristics. The scale can be attached to a moving object, such as a motor, even after assembly with associated mechanical components. This allows for easy measurement of the motor's operational mode. The light beam from a light-emitting device is directed to the label media, and the reflected light is received by a light-receiving device to identify individual objects based on the label.

His second patent pertains to an apparatus for measuring torque, inertia moment, output, and backlash. This invention measures characteristic parameters of a torque of a stepping motor and its associated driving current or voltage. By referencing these parameters against previously obtained data, Watanabe's apparatus can determine actual load torque and load inertia moment. Additionally, it calculates motor efficiency and backlash based on specific current waveform changes.
