Abstract: The present invention relates to a catalyst for hydrogenation of an aromatic compound, which is capable of greatly reducing the inactivation of a catalyst by using a support including a magnesium-based spinel structure, and a preparation method therefor.

Abstract: The present invention relates to a slide hinge apparatus and comprises a base frame wherein a space part is formed; a first slider that forms a space part to overlap with said space part of the base frame, and is furnished at the top of said base frame; a second slider that slides following said first slider; a hinge module that connects said first slider with the second slider so that these support each other elastically; a blocking plate furnished between said base frame and the first slider to move following a guide part and block the space part; and a first arm and a second arm that connect said hinge module with the block plate to rotate according to the motion of the hinge module and cause said block plate to slide. According to the present invention, both the slider and the block plate are effectively caused to slide simultaneously using the hinge module and a plurality of arms, thereby closing off the bottom of a liquid crystal screen (FPC) that is opened during sliding.

Abstract: The Ti—Ni—Mo shape memory alloy and fixating device for bone fractures using the same are provided, in which a very small amount of Mo of 0.5 at % or 0.7 at % is added Ni for to a Ti—Ni alloy, in order to maintain a transformation temperature whose martensite transformation start temperature (Rs) is 4-35° C. and whose inverse transformation finish temperature (Af) is 6-37° C. to be consistent, so that the transformation temperature can be applied to the human body most ideally, and enhance a corrosion resistivity. The Ti—Ni—Mo shape memory alloy is preferably made of Ti of 48-52 at %, Ni of 48-52 at % and Mo of 0.1-2.0 at %, in a composition ratio.
