Abstract: PURPOSE: A data managing device is provided to divide address areas into the first address area for directly managing data areas of a telephone memory, the second address area for indirectly managing the data areas by managing the first address area, and the third address area for managing deleted data areas, and to manage the second and the third address areas only, so as to quickly sort and store data in an EEPROM(Electric Erase Programmable ROM). CONSTITUTION: A controller decides whether new data is inputted in a memory(S10). If so, the controller decides whether values of a deletion counter, where a value corresponding to the amount of deleted data is written, are set(S20). If so, the controller confirms the third address area of the memory, and reads a direct address of a deleted address having a high priority(S30). The controller decreases one of the values of the deletion counter(S40). If the values of the deletion counter are set to "0" because of no deleted data, the controller reads an indirect address of the second address area, and reads a direct address of the first address area by the indirect address(S50). The controller writes the new data to be stored on a corresponding data area, and completes the process(S60).

Abstract: PURPOSE: A method is provided to achieve an improved user convenience while reducing the heating cost. CONSTITUTION: A stove comprises a main body(1) made up of a metal, a porcelain-clad plate wounded with a nichrome wire as a heater coil, a porcelain-clad plate cover made up of a metal, a combustion cylinder made up of a metal, a powder coal injection port, and a power switch. When the power switch is turned off and an open/shut-off element of a powder coal injection device filled with powder anthracite is opened, the powder anthracite flows into the combustion cylinder disposed onto the porcelain-clad plate cover through the powder coal injection port. When the powder anthracite contacts the porcelain-clad plate cover which is heated by the nichrome wire, an instantaneous ignition occurs by the action of gasification of the powder anthracite. Once the powder anthracite starts combustion, the powder anthracite is continuously burnt within the combustion cylinder in case where the supply of powder anthracite proceeds, even when the power switch is turned off. Such a heating operation is stopped by simply turning off the open/shut-off element of the powder coal injection device.
