Title: Innovations of Tatsuo Hara
Introduction
Tatsuo Hara is a prominent inventor based in Okaya, Japan, known for his significant contributions to the field of technology. He holds a total of 14 patents, showcasing his innovative spirit and technical expertise. His work primarily focuses on advancements in magnetic heads and timepiece mechanisms.
Latest Patents
One of Hara's latest patents is a method of manufacturing a magnetic head. This invention involves forming a magnetic core portion, a residual base material portion, and a connecting portion by pressing from a base material. Notches are created at the peripheral edge of the magnetic core portion, which is bent in the direction of the plate thickness to form a temporary fixing portion. When base materials are overlapped to cut the magnetic core portions from the connecting portion, the magnetic core portions are pressed toward one another, allowing the temporary fixing portion to fill between notches in the other magnetic core portion, thus temporarily fixing the other magnetic core portions. This method simplifies the temporary fixing process during the cutting step.
Another notable patent involves a mainspring used as a power source for a driving mechanism in timepieces. This mainspring is made of an amorphous metal sheet and features an S-shaped free-exploded design. The curvature changing point is strategically located on the inner end side of the middle point between the winding side and the outer end. The unique properties of the amorphous metal, including high tensile stress and low Young's modulus, enable an increase in the mechanical energy stored in the mainspring.
