摘要： The present invention relates to a flaky α-alumina crystal and a preparation method thereof. More particularly, the present invention relates to a flaky α-alumina crystal comprising aluminum oxide and zinc oxide, which is prepared by hydrolyzing an aluminum precursor solution containing a water-soluble flux and a zinc precursor solution to obtain a gel mixture and aging, drying, calcining and crystallizing it under a specific reaction condition, and a preparation method thereof. Since the flaky α-alumina crystal of the present invention has a thickness of less than 0.5 μm, an average particle diameter of at least 15 μm and an aspect ratio of at least 50, it is useful as high-quality pearlescent pigment material and filler for ceramic materials.

摘要： A device capable of opening/closing a door selectively closing an access opening of a main body at either side thereof comprises: at least a pair of hinge pins installed at the main body; a fixing member fixed on the door having pin guide grooves for the hinge pins; a pair of pin holders having a pin holding recess for accommodating radially said hinge pin and a pinion-toothed portion; a pair of rack-toothed portions provided on said fixing member to engage with said pinion-toothed portions of said pin holders, so that said pin holders rotate on their own axis when they are moving along said pin guide grooves; a pair of transverse sliders moving together with said pin holders; and a pair of latch members. The side surface of said transverse slider and corresponding outer end of said latch member has a contour relation that the transverse movement of said transverse slider causes the longitudinal movement of said latch member.
