Abstract: Provided is a method of synthesizing apatite powder by emitting a laser beam to a surface of a substrate immersed in a precursor solution. The method is including immersing a substrate in an apatite-forming precursor solution, emitting a laser beam to a region on a surface of the substrate immersed in the precursor solution, and obtaining apatite powder generated in the precursor solution.

Abstract: A gripper includes a body part, a finger base part coupled to the body part to be rotatable, the finger base part including a first finger base part and a second finger base part configured such that when the first finger base part is rotated in a first direction with respect to the body part, the second finger base part is provided to be rotatable in a second direction opposite the first direction with respect to the body part, and a finger part coupled to a first side of the body part or the finger base part to be reciprocal.

Abstract: A gripper includes a body part, a finger base part coupled to the body part, and a finger part coupled to a first side of the body part or the finger base part and coupled to the body part or the finger base part to be reciprocal, wherein the finger part comprises a first link structure and a second link structure, sides of which are coupled to the finger base part, respectively, and wherein, in the first link structure and the second link structure, a first support area of the first link structure and a second support area of the second link structure reciprocate in only one of a plurality of directions that cross a direction in which the finger part reciprocates with respect to the finger base part.

Abstract: An embodiment device includes an input module including a motor configured to generate a rotational force, an output module configured to receive power from the input module to be rotatable, and a connection module having a first side coupled to the input module and a second side, opposite the first side, coupled to the output module, wherein the connection module is configured to transmit the power from the input module to the output module.

Abstract: A slide mobile phone is provided. The slide mobile phone may include a first main body, a second main body connected to perform a sliding movement while contacting with the first main body, a rail formed along an inner side surface of the first main body, a keypad installed at the first main body and having a projection received in the rail in a side surface, and spring members installed within the first main body for supporting the keypad. The keypad can vertically move by extension and compression of the plurality of spring members when the second main body is moved according to an opening and/or closing movement.

Abstract: A mobile terminal having a supporting member is provided. The mobile terminal includes a main body having a first hinge portion, a first part mounted in the main body, and the supporting member having a second hinge portion connected to the first hinge portion. The supporting member is inserted into the main body and coupled to the main body by rotating about the first hinge portion. By integrally forming the main body of the mobile terminal and the supporting member, a manufacturing cost of the mobile terminal can be reduced and inadvertent loss of the supporting member by a user can be prevented. Further, when the supporting member is stored in a folded position in the main body of the mobile terminal, the supporting member can be used for aesthetic purposes and can provide an enhanced external appearance.
