Latest Patents

One of Kuramoto's latest patents is a power steering device that features a hydraulic actuator. This device generates steering assistance power by utilizing hydraulic fluid fed from a pump driven by a brushless electric motor. The innovative design allows for control of the motor's rotation speed, ensuring a preset steering assistance speed in a steering assistance mode, and a preset standby speed in a steering assistance release mode. Additionally, the motor's rotation speed is set to the steering assistance speed after being adjusted to a maximum speed that exceeds the steering assistance speed in the steering assistance mode.

Another significant patent is a torque sensor that includes two cylinders fixed to two shafts connected through a torsion bar. The magnetic coupling state of these cylinders is made variable in response to the relative rotations of the two shafts. This state is detected by a coil impedance, which indicates the torque acting on the shafts. The design features teeth with cutouts disposed circumferentially on the cylinders, ensuring that the two shafts are regulated by rotation to avoid complete opposition or non-opposition of the teeth.
