Title: Seiji Kikuchi: Innovator in Magnetic Sensor Technology
Introduction
Seiji Kikuchi is a prominent inventor based in Miyagi-ken, Japan. He has made significant contributions to the field of magnetic sensor technology, holding a total of 7 patents. His innovative work has led to advancements in the accuracy and efficiency of magnetic sensors.
Latest Patents
Kikuchi's latest patents include an assembling method for producing a magnetic sensor with high output accuracy. This method involves magnetizing the fixed layers of all magnetoresistive elements formed on the same substrate in the same direction. Chips containing these elements are cut out individually from the substrate, and a magnetic sensor is assembled by combining these chips while considering the magnetization directions. This approach ensures that the fixed layers are magnetized by a sufficiently strong magnetic field, resulting in an output signal with a large absolute value.
Another notable patent is for a magnetic switch capable of instantaneous switching of an output signal and magnetic sensor. This magnetic switch utilizes magnetoresistive elements with free layers whose magnetization directions can be altered by an external magnetic field. It features two magnets that produce distinct magnetic fields, which are opposite in direction and vary in strength. A magnetic shield member moves between positions to control the magnetization of the free layers, enhancing the functionality of the switch.
