A cathode active material capable of increasing a capacity and improving high temperature characteristics or cycle characteristics, a method of manufacturing it, a cathode using the cathode active material, and a battery using the cathode active material are provided. A cutting device is provided that cuts into the insulation to be removed perpendicular to the fiber. The conductive metal layer completely covers the substrate layer, and has a critical dimension bar corresponding to a desired CD. The clock recovery circuit includes a phase detector, charge pump, controlled oscillation module and a feedback module. The switch actuator may be made from a material having a higher melting point than the housing so that ultrasonic welding may be performed on the circuit module package without joining the switch actuator permanently to the circuit module package assembly. A post-migration authentication server receives a first template and a second template from a post-migration authentication terminal, performs authentication on the basis of the comparison result between the received first template and the user’s preliminarily first enrolled template, and provisionally enrolls the first template and the second template.
