Title: **Tsunemasa Okumura: Innovator in Wheel Technology**
Introduction
Tsunemasa Okumura, based in Aichi, Japan, has made significant contributions to the field of wheel technology. With two patented inventions to his name, he has demonstrated innovation and creativity in enhancing the design and functionality of wheels.
Latest Patents
One of Tsunemasa Okumura's latest inventions is a revolutionary **Cast Wheel**. This full face type cast wheel features a rim portion designed to hold a tire, which is integrally cast with a disk portion. A standout element of this design is a side wall portion that extends from the dropped portion of the rim to the bead seat, along with a series of recessed portions. These recessed areas, defined intermittently along the circumferential direction, serve to reduce the weight of the wheel, prevent blowhole generation during the casting process, and enhance the air capacity of the tire.
Another notable patent by Okumura is a **Method for Processing a Nut Seat on a Wheel**. This innovative technique involves drilling the nut seat and bolthole simultaneously using a step drill, followed by roller burnishing the edge portions of the nut seat. This method ensures that at least the edge portions achieve a specular finish, significantly increasing the strength of the nut seat. Consequently, this allows for a reduced thickness of light alloy wheels, thereby decreasing their overall weight while also expediting the processing time.
