Abstract: Proposed is a foldable hinge module for a portable terminal, and more particularly, a foldable hinge module for a portable terminal that can easily unfold or fold a flexible display mounted on the portable terminal. In the foldable hinge module for a portable terminal, the flexible display can be smoothly unfolded or folded as the first rotary plate and the second rotary plate are easily rotated in the Y axis direction, by using the gear set part engaged with the first gear part formed in the first rotary plate and the second gear part formed in the second rotary plate to be operated.

Abstract: A hinge device for a rotary door is mounted to a door that is rotating to open and close the door while being rotated in various manners. The hinge device can be rotated in a free stop type in a predetermined section after it is rotated by an external force, and is automatically reversely rotated in a section in which it is reversely rotated after the free stop rotation.

Abstract: Disclosed herein is a screen base capable of allowing at least one base to be rotatably coupled to a vertical bar which extends to a lower end of a screen, and of adjusting an installation angle of the base. The screen base, which is coupled to the vertical bar extending to the lower end of the screen and supports the screen, includes a base including a body which has a hollow shape and is rotatably coupled to the vertical bar, and an extension portion which is formed to extend outward of the vertical bar from the body; and a fixing unit to fix the body with respect to the vertical bar.

Abstract: A structurally improved rail-type device for mechanically splicing optical fibers while reducing the splicing loss is disclosed. The above splicing device not only has a cladding clamp with a seesaw structure thereby easily splicing the optical fibers, it also separately moves the covers relative to the body to easily perform the tuning operation. Due to coating clamp's protrusions and body's slots engaging with each other, the coating clamp exclusively vertically move relative to the body and prevent the optical fibers from being axially thrust. The splicing device further seperately clamps the coating and cladding parts of the optical fibers, thereby preventing the spliced fibers from breaking due to tensile or torsional force. The sliding motion of the covers relative to the body is achieved by the rails of the covers and rail grooves of the body.
