Title: Makoto Sei: Innovator in Magnetic and Battery Technologies
Introduction
Makoto Sei is a prominent inventor based in Makinohara, Japan. He has made significant contributions to the fields of magnetic and battery technologies, holding a total of 5 patents. His innovative designs focus on enhancing the efficiency and cost-effectiveness of current detection and battery temperature sensing.
Latest Patents
One of his latest patents is for a magnetic permeable member and current detection device. This invention allows for the detection of current across a wide range using a magnetic field detection element at a low cost. The design features a magnetic permeable member that includes both a closed portion and an opened portion. When a large current flows through a bus bar, the magnetic field is less intense at the opened portion, making it easier to detect the large current. Conversely, when a small current flows, the magnetic field is stronger at the closed portion, allowing for effective detection of the small current. This dual functionality enables the common use of magnetic field detection elements, thereby reducing costs while maintaining a wide detection range.
Another notable patent is for a battery temperature sensor and its attachment structure. This sensor includes a sensor body and an electric wire connecting connector. The sensor body is designed to be detachably attached to a mating body and features a first locking member for secure attachment. The temperature measuring element is integrally formed within the sensor housing. The electric wire connecting connector also has a detachable design, with a second locking member and terminals that connect to the sensor housing when coupled. This innovative design enhances the reliability and ease of use of battery temperature sensors.
