A cutting device for cutting a material and providing a cut portion of the material. This pulsed beam is indirectly relayed to side-looking missile-borne receivers by way of scattered radiation effected by atmospheric particles. The registered digital image is provided to the second computer over the global computer network. The user of the data recording and reproducing apparatus quickly finds the desired video image by actively utilizing the random access property of the MO disc device and sequentially inputs the same to the VTR device, records the same on the video tape, and performs the editing of the audio andor visual data. According to an exemplary embodiment, an electrically conductive device includes a graphene layer on a substrate, a protein tube portion on the graphene layer, and a conductor penetrating through the protein tube portion to the graphene layer, wherein the conductor is in electrical contact with the graphene layer. The diaphragm blade rotated alternately between the first and second stationary positions due to an interaction between a generated magnetic field upon passing an electric power, and a magnetic field generated due to the magnet.
