Latest Patents

One of Nakakubo's latest patents is a damping member for rolling guide devices. This invention provides a damping member that can be easily mounted to existing rolling guide devices without increasing their size. It enhances the damping force in the axial direction, improving the overall functionality of the device. The damping member is designed to be applied to a rolling guide device where a moving block is assembled to a track rail through multiple rolling elements. It includes a friction member with a sliding contact pad that presses against the track rail, and a fixing holder that couples the friction member to the moving block.

Another notable patent is a vertical seismic isolation apparatus. This device consists of a fixed frame and a movable frame arranged on it, allowing only vertical movement. The support guide mechanism converts the vertical movement of the movable frame into motion of the moving block, ensuring stability during seismic events. The design includes a support leg and an auxiliary leg, which work together to maintain a constant distance between the frames.
