Latest Patents
Among his latest patents is a magnetic transducing assembly that features an elongate magnetic flux carrying core member. This assembly includes a substrate with a flat multi-turn spiral on its surface and a slit opening at the center of the spiral. The core is engaged in the slit, aligning the plane of the spiral with the elongate direction of the core, allowing the spiral to form a coil around the core member. Another notable patent involves a method of bonding laminations of a magnetic core. This method utilizes photo-resist material, consisting of a co-polymer, applied as a film to a sheet of magnetic material to define lamination shapes. The laminations are formed by etching, and the film is used to bond the laminations together in a stack. To ensure the core operates at higher temperatures, the bonded stack is irradiated to modify the bonding material, preventing it from softening at the core's operating temperature.
