Title: Michiyuki Kamiji: Innovator in Magnetic Encoder Technology
Introduction
Michiyuki Kamiji is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of magnetic encoder technology, holding a total of nine patents. His innovative approaches have led to advancements in manufacturing methods and design.
Latest Patents
One of Kamiji's latest patents is a magnetic encoder manufacturing method. This method involves creating a magnetic encoder where a support member and a plastic magnet do not adhere to each other during the manufacturing process. The plastic magnet features a turning molded portion on its outer circumferential side. The mold used has an inner-diameter-side disk gate, with a specific length in the axial direction ranging from 0.2 mm to 0.6 mm. The tensile strength of the plastic magnet material is 65 MPa or more, and its Young's modulus is between 4000 MPa and 15000 MPa. The method includes steps for opening the mold, placing the support member as an insert object, and injecting melted plastic magnet material into the cavity through the disk gate.
Another notable patent is related to a rotary seal. This invention addresses the radial gap between the outer circumferential surface of an encoder member and the inner circumferential surface of a seal body. The design includes a first gap portion and a second gap portion, with the first being a cylindrical surface and the second being conical, gradually increasing in radial gap as it approaches the inward flange portion of the core metal.
