Title: Hirokazu Miyamoto: Innovator in Angle Detection Technology
Introduction
Hirokazu Miyamoto is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of angle detection technology. With a total of 2 patents to his name, Miyamoto continues to push the boundaries of innovation in his area of expertise.
Latest Patents
Miyamoto's latest patents include an angle detecting apparatus and an angle detecting method. The first patent describes an angle detecting apparatus that features a rotor fixed to a rotating shaft. It includes a pair of magnetic sensors arranged close to the rotor's outer periphery, which have a difference in angle of (π/2) with respect to the center of rotation. A differential operational circuit processes the detection signals from the magnetic sensors to output a differential signal. An angle calculating circuit then determines the angle of rotation based on this differential signal. The rotor's planar shape is designed so that the sum of the distances between the center of rotation and two specific points on the rotor's outer periphery remains constant, ensuring symmetry with respect to a straight line passing through the center of rotation.
The second patent also focuses on an angle detecting apparatus, which includes a rotor and a pair of magnetic sensors positioned opposite each other. These sensors output first and second detection signals that contain information about the rotor's angle of rotation. A differential operational circuit performs operations on these signals, while an angle calculating circuit computes the angle of rotation based on the results. The design ensures that the distance between two points where a straight line crosses the rotor's outer periphery remains constant.
