Latest Patents
One of Naoki Akira's latest patents is for a paper feed roll designed to inhibit conveyance failure during long-term use. This invention addresses the issue of unevenness in the surface of an elastic material layer, which is crucial for maintaining consistent performance. The paper feed roll features a shaft body and an elastic material layer that includes a first phase of ethylene propylene diene rubber and a second phase of either isoprene rubber or natural rubber. The area ratio of the second phase is maintained between 30% and 70% within a specified range, ensuring optimal functionality.
Another notable patent is for a conductive roll intended for use in electrophotographic machines. This conductive roll serves as a charging roll and consists of a shaft body with an elastic body layer formed on its outer periphery. The elastic body layer is a crosslinked composition that includes a diene-based polymer, a sulfur or peroxide crosslinking agent, carbon black, and a coupling agent. The specific surface area of the carbon black and the composition ratios are carefully controlled to enhance the performance of the roll.
