Filed: 2001-12-11
Abstract: PURPOSE: A data managing system for a mobile communication terminal and a method therefor are provided to give a sufficient data storage space to a user by forming a folder managing server connected to a mobile communication network and allowing the user to store data there or transferring his/her radio contents data to someone. CONSTITUTION: A user inputs a mobile terminal number and connects to a mobile communication network(201). It is judged whether to upload a file stored in a memory of the mobile terminal or transfer the file to someone(202). If the user selects uploading, he/she searches the memory to select a file to be uploaded(203). The user connects to a folder managing server and selects a folder which has been created when he/she subscribed as a member(204,205). The selected file is copied or clipped and stored in the folder(206). If the user wants to transfer a file to someone, the mode is changed(210). The user searches the memory and selects a file desired to be transferred to someone(211). The user inputs a mobile terminal number of a receiver(212), and transfers the file(213).

Title: Roll etching method using laser
Inventor: EO JI HO
IPC: B23K26/362
Filed: 2001-12-21
Abstract: PURPOSE: A roll etching method using a laser is provided to efficiently transmit information and to improve a working efficiency by using continuous on/off signals when forming a pattern. CONSTITUTION: A number of pixels having continuous same patterns are checked from etching patterns (S401). Then, laser on/off with respect to the patterns is determined and a laser control signal is outputted (S403). After that, a roll is etched by radiating laser beam onto the roll corresponding to the number of pixels having the continuous same patterns. When radiating laser beam, next etching pattern data are read in advance. The roll is again etched by radiating laser beam onto the roll corresponding to the number of pixels having the continuous same patterns through reversing a phase of laser beam.

Abstract: PURPOSE: To provide a battery cap unit which prevents degradation of accuracy of a protection unit by using a heat sensitive switch as one and can constitute a compact, fit for assembly, and low-cost battery by integrating and unitizing the protection unit with a battery cap body. CONSTITUTION: The unit is provided with a metal battery cap body 2 sealing a battery cell 1 used for a secondary battery and shielding the inside of the cell, and a heat sensitive switch 4 making changeover of switching at a given temperature, and it is so structured that the heat sensitive switch 4 is fitted to the battery cap body 2 and the heat sensitive switch 4 and the battery cap body 2 are integrated, to aim at unitization.
