Latest Patents

Morita's latest patents include a magnetic rotary encoder designed for the detection of incremental angular displacement. This innovative device utilizes magneto-resistors to detect angular velocity and rotating direction. The rotary member can be a drum, disk, or cup-shaped and is attached to a rotatable shaft. A magnetic medium on the rotary member's surface is divided into multiple magnetic sections, each containing a recorded magnetic signal. As the rotary member revolves, it produces an alternating magnetic field. The magnetic field detector, which includes at least one magneto-resistor, generates an analog signal that represents the electrical resistance change corresponding to the rotational angle of the rotary member.

Another notable patent is a digital servo control system that responds to command signals indicative of a moveable element's position. This system develops a motor drive signal to position the motor accurately. It operates in both velocity control and position control modes, ensuring precise movement of the controlled element.
