| Aichi Steel Corporation (Headquarters:
Tokai-city, Aichi prefecture; President: Yuji Shibata) and its subsidiary, Aichi Micro
Intelligent Corporation (AMI / Headquarters: Tokai-city, Aichi prefecture; President:
Akiyoshi Morita) have jointly developed a three-dimensional Magnet Impedance (MI)
sensor-based magnetic field canceller. The canceller, named "Palm Gauss," will
be released in November 2002. A magnetic field canceller, which provides a nonmagnetic field or a minute magnetic field, is used for electron microscopes and in neuromagnetic field diagnosing rooms. Since Aichi Steel succeeded in developing a high-sensitivity magnetic sensor based on the amorphous MI effect last year, developing a minute magnetic field and its industrial applications has become a priority, requiring a compact magnetic field canceller. "Palm Gauss" jointly developed by Aichi Steel and AMI is a device that provides a palm-sized nonmagnetic field or minute magnetic field. A micromini three-dimensional MI sensor detects a magnetic field and three-dimensional coil compensates it to create a nonmagnetic field. Miniaturization was achieved by solving the mutual interference problem particular to a three-dimensional sensor and successfully producing a micromini three-dimensional MI sensor. This new product is expected to be used in the research of a minute magnetic field in the fields of information, biology and the environment in the future.
