Title: The Innovative Mind of Shigeru Shouji
Introduction
Shigeru Shouji, a prominent inventor based in Hamamatsu, Japan, has made significant contributions to the field of technology with his 16 patents. His work primarily focuses on advancements in magnetic head slider fabrication and thin film magnetic heads, showcasing his innovative prowess within the industry.
Latest Patents
One of Shouji's latest patents is the "Fabrication of Rail of Magnetic Head Slider." This intricate process involves forming a first resist mask on a rail, which covers areas where shallow and deep surfaces are not present. A first etching process is then executed to etch the rail to a depth corresponding to the shallow surface. Following this, without removing the initial resist mask, a second resist mask is added over the shallow surface area. A second etching process thereafter removes material not covered by either mask, achieving the depth needed for the deep surface. Finally, both masks are removed, revealing the completed rail.
Another significant patent is for a "Thin Film Magnetic Head with Special Pole Configuration." This design begins with a substrate where a lower pole is embedded in a protective film. A gap layer is formed on this film, followed by the creation of a first upper pole which faces the lower pole. A protective film is then made coplanar with the upper surface of this first upper pole. On it, a coil consisting of multiple layers is formed, embedded within an insulating film. Lastly, an upper core layer is created, leading to a second upper pole that is magnetically coupled with the first upper pole, resulting in an innovative upper pole configuration.
