Abstract: A mobile device comprises a functional arrangement for performing a function of the mobile device, a coupling device for connecting the mobile device to a stationary device, an authentication device for authenticating the stationary device and an activation device. The authentication device authenticates the stationary device based on information on the stationary device. The activation device activates the functional arrangement when the mobile device is connected to the stationary device by the coupling device, and when the stationary device has been authenticated by the authentication device.

Abstract: A method for producing an intermediate glass plate includes a defect formation step, a separation step, and a polishing step. In the defect formation step, a defect is formed on main surfaces of glass blanks by irradiating a laminate of the glass blanks with a laser beam from one side in a lamination direction in which the glass blanks are laminated, along the lamination direction, and moving the laser beam relative to the laminate such that a circle is drawn in a view from the main surfaces of the glass blanks. In the separation step, a cylindrical laminate is formed by separating a removal target portion along the defect while maintaining the laminate. In the polishing step, a side wall surface of the laminate is polished while maintaining the cylindrical laminate so as to obtain a disk-shaped intermediate glass plate that has been subjected to edge surface polishing.

Abstract: A substrate for a magnetic disk includes a substrate main body having a disk shape and an alloy film. The substrate has a thickness (T+D) of 0.520 mm or less, which is the sum of a thickness T of the substrate main body and a thickness D of the film formed on main surfaces of the substrate main body. The disk shape has an outer diameter of 90 mm or more. A ratio D/T of the thickness D to the thickness T is 0.025 or more. The thickness of the film formed on an outer circumferential edge surface of the substrate main body is greater than the thickness of the film formed on each of the main surfaces, and the thickness of the film formed on each of the main surfaces is 80% or more of the thickness of the film formed on the outer circumferential edge surface.
