With a total of 13 patents to his name, Satodate continues to push the boundaries of innovation.

Latest Patents

Among his latest patents, Satodate has developed a rolling bearing that achieves a reduction in torque. This innovative rolling bearing consists of an inner ring and an outer ring that are coaxially aligned, with a rolling element positioned between them. A seal member covers the area between the inner and outer rings, while filled grease is strategically placed between the rolling element and the seal member. The grease features a first ring-like part that contacts one of the rings and a second ring-like part that connects to the first and contacts the seal member.

Additionally, Satodate has created an inertial force imparting device designed to prevent the intrusion of dust and moisture. This device simulates a kinetic operation feeling in response to user actions and generates vibrations as needed. It includes a stator, a movable mover, a weight attached to the mover, and an actuator unit with a shape memory alloy wire. This wire changes length based on temperature, allowing for precise control of the mover's position.
