Abstract: Disclosed is an apparatus for coupling an SiC reflex mirror, configured to mount an SiC reflex mirror formed on a plurality of points and having a cylindrical portion on one surface thereof, to a mounting plate. The apparatus includes: an insertion portion having a vertical portion having a curved shape and attached to inside of the cylindrical portion, and a horizontal portion integrally formed with the vertical portion and formed to cross the vertical portion; an adhesive provided between the vertical portion and an inner circumferential surface of the cylindrical portion, and configured to attach the insertion portion to the cylindrical portion; a fixing portion having one end fixed to the horizontal portion, having another end fixed to the mounting plate, and configured to fix the SiC reflex mirror to the mounting plate; and a coupling member configured to fix the fixing portion to the insertion portion.

Abstract: The present invention relates to measurement of cross-inertia-moment in a limited angular rotatory axis, and more specifically, to a measuring device and method of cross-inertia-moment in a limited angular rotatory axis. The measuring device includes a base plate; a pair of first supporters, each end portion being secured on the base plate through a load cell, for supporting a first rotatory axis; a second supporter installed inbetween the pair of first supporters to be able to rotate round the first rotatory axis, for supporting a second rotatory axis that is orthogonal to the first rotatory axis; and a roller installed at the inside of the second supporter, being rotatable round the second rotatory axis. Therefore, the present invention enables to measure and amend the cross-inertia-moment of multiple axis LOS (line of sight) stabilizer as well as low speed rotatory machinery.
