    摘要： A rotary compressor may include a rotary shaft; a plurality of plates that supports the rotary shaft; a cylinder provided between the plurality of plates to define a compression space, and provided with a vane slot; a roller slidably coupled to the rotary shaft inside of the cylinder, and having a hinge groove on an outer circumferential surface thereof; and a vane, a first end of which is slidably coupled to the vane slot of the cylinder, and a second end of which is rotatably coupled to the hinge groove of the roller. At least one of first and second axial end surfaces of the roller facing the plurality of plates is provided with a dimple portion having a predetermined depth. With this structure, contact surfaces between the roller and the plate may be prevented from being in close contact with each other.

    摘要： A method for manufacturing graphene using light capable of transferring and patterning graphene, and graphene manufactured using the method are disclosed. The method includes forming a graphene layer on a catalyst metal layer, attaching a support layer losing adhesion by light on the graphene layer, removing the catalyst metal layer, disposing a substrate on the graphene layer, and separating the support layer from the graphene layer by irradiating light to the support layer.
