Title: The using method and the coloring agent of liquid to color cement structures
Inventor: JEONG WON WOOK
IPC: C09D17/00
Filed: 2000-06-27
Abstract: PURPOSE: Provided are a liquid colorant for coloring various secondary cement processed goods, which can prevent the generation of dust and dose not pollute the environment, and a method for using the same. CONSTITUTION: The liquid colorant comprises about 30% (based on the produced composition of 100%) of pigment powder, about 20% of a liquid surfactant for dispersing the pigment equally, about 15% of a liquid polymerizing agent for preventing discoloration caused by sunlight, about 5% of a dispersing agent, about 5% of additives, and about 25% of mineral water. And the liquid colorant can be used by mixing with cement or coating on cement structures.

Title: Method of erasing a flash memory device
Inventor: AHN BYEONG JIN
IPC: G11C16/34
Filed: 2000-06-27
Abstract: PURPOSE: A method for erasing a flash memory device is provided, which has a constant erase speed in spite of a variation of an internal voltage, and can solve an over-erase problem by performing an erase operation by controlling an erase pulse according to an erase state. CONSTITUTION: According to the method, a pre-program and its verification are performed to increase a threshold voltage of cells of a selected sector. An erase is performed by applying an erase voltage of a unit pulse in an address unit after resetting an address counter of the selected sector. An erase state of the whole cell of the address is verified, and if the whole cell of the address is erased, then an erase is performed to the final address by increasing the address. If the whole cell is not erased, the whole sector is erased and it is verified that the number of erase exceeds the maximum erase number. If the number of erase does not exceed the maximum erase number, the number of erased cell is checked. When the number of erased cell is lower than the minimum number of erased cells, an erase is performed by applying an erase voltage whose pulse width is increased. When the number of erased cells is higher than the maximum number of erased cells, an erase is performed by applying an erase voltage whose pulse width is decreased. When, the number of erased cells lies between the minimum number and the maximum number of erased cells, an erase is performed by applying an erase voltage whose pulse width is not controlled. When the number of erase exceeds the maximum erase number, the device is judged to be defective and the erase ends.
