Abstract: PURPOSE:To minimize the capacity of a storage means for reference places by deciding on a reference place on the basis of input area data, reading the corrected place of a representative value having the deepest relation on the basis of the reference place and input area, and correcting it and calculating a proper corrected value. CONSTITUTION:Data on an area is stored in an area data temporary storage circuit 70 through an input control circuit 11 and a reference place decision circuit 80 decides which section in 'tidal section figure' the input area belongs to and where the reference plate of the section is. An arithmetic circuit 60 reads tide data out of a tide data storage circuit 40 and reads a calculation expression out of a calculation expression storage circuit 30 to perform arithmetic. A correcting value reading circuit 90 reads a tide correcting value for a representative place closest to a reference place. The tide correcting value is calculated by a correcting value calculating circuit 100 and the correction result is displayed on a display body 130.

Abstract: PURPOSE:To prevent a defect in operation on a main storage device, etc., even if a CPU is replaced and the frequency of a clock is varied by including both OUT and IN pulses in operation pulses of a computer, and altering them and leaving a time between oscillations of both the pulses. CONSTITUTION:The input terminal A of a pulse modulating circuit system 2 is connected to the pulse oscillating circuit 1 that the personal computer originally has and when a pulse train that the clock oscillates is inputted to the input terminal A, a modulated pulse train is outputted from the output terminal B. This pulse train consists of pulses twice as many as those of the clock and a long pulse interval and a short pulse interval are alternated. Namely, the CPU reads data out of a main memory 3 at a pulse rise after the short pulse interval and writes data in the memory 3 at a rise after the long pulse interval. The interval from the reading to the writing of the memory 3 is longer than pulse intervals in the modulated pulse train. The pulse intervals are a half as long as the original intervals and the number of operations is twice.
