Title: Kouichirou Matsumoto: Rotation-Angle Detection Inventor
Introduction
Kouichirou Matsumoto is an inventor associated with Kariya, Japan. His work includes technologies for detecting rotational angles using magnetic sensors. He is credited with 3 patents.
Latest Patents
Matsumoto’s listed patents include two rotation-angle detection inventions. The first, “Rotation Angle Detecting Device,” uses a permanent magnet and a pair of magnetic sensor elements to generate output signals as an object rotates. A calculating unit determines the phase difference between the signals to calculate the rotation angle.
The second, “Rotation Angle Detecting Device with a Selecting Means for Selecting a Pair of Output Signals of the Magneto-Sensing Elements,” uses a magnetic-field-forming member, magneto-sensing sections, and a selecting circuit. The circuit chooses the pair of sensor output signals whose phase difference is closest to a preset angle.
