Abstract: An electronic apparatus includes a casing and a foldable display screen. The casing includes a first frame, a middle frame having a first side and a second side opposite the first side, and a second frame. The first frame is rotatably attached to the first side of the middle frame and the second frame is rotatably attached to the second side of the middle frame. The foldable display screen includes a back surface attached to the casing and a display surface opposite the back surface. The display foldable screen is folded along the first side of the middle frame to be in a first state, and is folded along the second side to be in a second state. The display surface is invisible in the first state. Part of the display surface is visible and remaining part of the display surface is invisible in the second state.

Abstract: The present invention provides a microporous carbon material capable of expressing functions that supported metal has while maintaining pore functions that the microporous carbon material inherently possesses. The microporous carbon material 5 includes: a three-dimensional long-range ordered structure within a range from 0.7 nm or more to 2 nm or less; and micropores 2a, wherein a transition metal 4 is supported on surfaces of the micropores 2a. The microporous carbon material is obtained by a method including: introducing an organic compound on a surface of and inside the micropores of a porous material containing transition metal, and obtaining a composite of the microporous carbon material containing the transition metal and the porous material by carbonizing the organic compound by a chemical vapor deposition method; and removing the porous material.

Abstract: A stylus retaining mechanism for portable electronic device includes a main body, a latching portion, and an elastic member. The main body defines an opening and a receiving chamber communicating with the opening. The latching portion is positioned at one side of the receiving chamber spaced from the opening. The elastic member is fixed in the receiving chamber adjacent to the opening. The stylus is received in the receiving chamber. The elastic member prevents the stylus from separating from the main body when the stylus is disengaged from the latching portion.
