Abstract: PURPOSE: An overcurrent protecting circuit and a method are provided to prevent the fire or the combustion due to an overcurrent without increasing an amount and size of the elements by using the micom to cut off the power when detecting the abnormal state of the circuits. CONSTITUTION: Data for checking the abnormal state is transferred to a load. Whether a response signal with respect to the transferred data is received is checked. If the normal response signal is not received, the load is determined to be abnormal. If the load is determined to be abnormal, the power source supplied to the load is interrupted. The overcurrent preventing circuit comprises a controlling means for checking the operation of the load, the first switching means turned on and off by a controlling signal outputted in the controlling means, and the second switching means turned on and off by the on and off of the first switching means and supplying and interrupting a power source.

Abstract: PURPOSE: A refresh circuit is provided to reduce the power consumption during refresh operation by reducing mean current during the operation. CONSTITUTION: The refresh circuit includes a memory cell array(11), a row decoder(12), a sub word line driver, a vertically word line generator(14), a refresh counter(15), an input buffer(16) and a turn-check member(17). The row decoder generates a global word line. The sub word line driver receives a vertically word line output and a global word line output from the vertically word line generator and a row decoder and generates final sub word line. The vertically word line generator receives an output signal of the turn-check member and an arbitrary number of upper bit of the refresh counter and delivers the result on the sub word line driver as one input signal. The refresh counter multiplexes the address applied from outside with the address generated inside by allocating the address for generating input signal on the vertical word line generator on the upper portion while allocating the rest on the lower portion. The input buffer receives all external input signals and determines self refresh. The turn-check member only operates only when all of the address but the address of arbitrary upper bits are of logic high or low levels.

Filed: 2000-01-22
Abstract: PURPOSE: A deciding method of cooking finish time in a microwave oven is provided to decide the time point having the cooking state value of cooking material reaches specific set value, as the finish time of cooking. CONSTITUTION: A microcomputer generates microwaves from a magnetron and rotates a turntable when a user puts popcorn in a cavity and selects a cooking mode. The microcomputer obtains the maximum value and the minimum value of 20 detected data from each rotation of the turntable and operates the difference(C) therebetween. The microcomputer multiplies the maximum difference(C') of 5th rotation by a first set coefficient(A) when the turntable is rotated 5 times. Then the microcomputer multiplies the maximum difference(C') of 8th rotation by a second set coefficient(B) if the turntable is rotated 8 times. The microcomputer performs the cooking mode by increasing the 1cycle of the turntable. The microcomputer obtains the maximum difference(C') of 9th rotation and multiplies the difference by the second coefficient. The microcomputer finishes the cooking mode if the multiplied value is similar to the difference of the 10th rotation. Therefore, the microwave oven provides convenience to a user by automatically cooking various foods through simple operation of a function key.
