Latest Patents

One of his latest patents is a stabilizer designed to reduce displacement between the right and left wheels of a vehicle. This stabilizer is formed using a metal bar with a solid structure and includes a torsion part that extends in the vehicle's width direction. It is capable of torsional deformation and has a diameter ranging from 10 to 32 mm. The stabilizer's chemical composition contains at least C: 0.15% by mass or more to 0.39% by mass or less, along with Mn, B, and Fe. Additionally, it features a metal structure that is 90% or more martensite.

Another significant patent is the production method for stabilizers, which allows for high productivity in a compact production line without the need for tempering. This method involves forming a steel bar material containing at least C: 0.15 wt % to 0.39 wt %, Mn, B, and Fe into a product shape by bending. The bent steel bar material is then quenched in a medium with a heat transfer coefficient close to that of water.
