Latest Patents

One of Ikeda's latest patents is the metal graphite grounding brush, which is primarily composed of silver. This brush is designed to make slide contact with the peripheral surface of an axle, effectively grounding it. The mass ratio of silver to carbonaceous components in the brush is crucial, with silver comprising over 30% and up to 90%, while carbonaceous components make up less than 70% and down to 10%. The volatile component in the brush is maintained between 2.0% and 15%. This innovative design not only reduces noise from car radios but also ensures a long service life and mechanical strength.

Another notable patent is related to a commutator used in rotary electric machines. In this design, each commutator segment features a low-resistive layer made from a low-resistive material and a high-resistive layer made from a high-resistive material. The low-resistive material includes a carbonic material and a binder, while the high-resistive material contains a carbonic material, a binder, and an inorganic substance such as boron nitride. The mixing ratio of the inorganic material to the high-resistive material exceeds 20 wt%. This innovative approach enhances the performance and reliability of the commutator.
