  • Magnetic field measuring device
    Patent number: 9581426
    Abstract: The present invention provides a magnetic field measuring device comprising first to fourth magnetoelectric transducers, magnetic convergence plates, and a calculation unit that calculates the strength of a magnetic field applied in a horizontal direction and/or a vertical direction with respect to a magneto-sensing surface of the magnetoelectric transducers, wherein the magnetic convergence plates are placed in the vicinity of the first to fourth magnetoelectric transducers so as to convert magnetic field vectors, and the calculation unit includes a first calculation block that adds or subtracts output from the first to fourth magnetoelectric transducers, and outputs a calculation result.
    Type: Grant
    Filed: July 27, 2012
    Date of Patent: February 28, 2017
    Assignee: Asahi Kasei Microdevices Corporation
    Inventors: Junichiro Okamoto, Arata Takahashi
