Title: the method of managing cellular phone with low battery
Inventor: KIM JAE HUI
IPC: H04B7/00
Filed: 2002-10-14
Abstract: PURPOSE: A method for managing a mobile phone in a power low state is provided to inform the other side that the power of a user's mobile phone has been turned off due to weak power, in order to avoid misunderstanding that the user hung up on purpose. CONSTITUTION: In case that the power of a mobile phone gets low, the mobile phone transmits a power low message to an MSC(Mobile Switching Center) through a base station(S10). The MSC stores the power low message in a database and manages the mobile phone in a power low state(S20). In this state, if the power of the mobile phone is turned off in the middle of telephone conversation, the MSC judges whether the other side is maintaining the traffic path(S30). In case that the other side is still maintaining the traffic path, the MSC sends an announcement to inform the other side that the line has been cut off due to a shortage of power(S50). Then the MSC executes an operation to automatically remove the traffic path(S60).

The throwaway insert (1) comprises a major cutting edge (60) including a tapered cutting edge (61) connected to a cutting edge (41) of a nose portion (40), and a curved cutting edge (62) connected to an end of the tapered cutting edge (61) at a connection point (P). The curved cutting edge (62) is formed so as to extend along an imaginary cylindrical surface (S) whose center axis coincides with the axis of rotation of a tool main body (200), and tapered cutting edge (61) is formed so as to gradually curve from the imaginary cylindrical surface (S) toward the inside of the imaginary cylindrical surface (S) as the distance from the curved cutting edge (62) increases, and the distance from the nose portion (40) decreases. The throwaway insert (1) is attached to the tool main body (200) in which the surface of the distal end thereof is machined so that surface roughness thereof is less than 3.2  mu m when indicated by the Ry roughness. <IMAGE>
