Latest Patents

Ezaki's latest patents include an insertion guide and an insertion guide device. This invention provides an insertion guide that performs accurate rotation correction between a shaft and a hole, as well as phase correction between the shaft and hole. The design features a first guide portion at the distal end of the shaft, which has a diameter smaller than that of the hole. Additionally, there is a second guide portion on the base end side of a first narrow cylindrical portion, which has a diameter smaller than the hole but larger than that of the first narrow cylindrical portion. The third guide portion is a recessed area at the distal end of the shaft, designed to engage with a protruding portion formed in the hole. This innovative design allows the shaft, when inclined with respect to the hole, to make contact at two points or less before the third guide portion engages with the protruding portion.

Another notable patent is a mirror replacement device for a segmented mirror telescope, along with its corresponding mirror replacement method. This device includes a gripping mechanism to hold a segment mirror, a fine drive mechanism to adjust the position and posture of the gripping mechanism, and a lift mechanism for the segment mirror. It also features detectors to monitor the relative position and posture between a comparison object and a target object, as well as to detect any bending of the fine drive mechanism. The mirror replacement controller operates based on detection signals from these detectors, ensuring precise control during the mirror replacement process.
