Abstract: PURPOSE:To forecast the latest amount of rainfall at short intervals of time by calculating the gravity center point of the rainfall amount and rainfall density from a rainfall amount distribution chart obtained by calibrating raindrop data obtained by a radar rain gauge with rainfall amount data obtained by a ground rain gauge. CONSTITUTION:A forecasting device 3 calibrates the raindrop data from the radar rain gauge 1 with rainfall amount data from the ground rain gauge 2 at prescribed intervals of time to generate a rainfall amount distribution chart at prescribed intervals of time, thereby calculating the rainfall amount gravity center and rainfall density.

Further, the transition track of the rainfall density is found from the difference in rainfall density between adjacent times. Further, the future moving speed forecasted value and rainfall density forecasted value are calculated from the moving speed data on the rainfall amount gravity center point and the transition track of the rainfall density. Here, the mean value of the amount of rainfall in an area traced back on the movement track of the estimated object area by a moving speed forecasted value is found and multiplied by a variation coefficient obtained from the rainfall density forecasted value to obtain the rainfall amount forecasted value of the object area to be forecasted.

Abstract: PURPOSE:To attain the protection of an output element as well as to ensure the high-speed responsiveness with a simple constitution, by providing plural Zener diodes, a diode, a resistance, etc. between the drain and source terminals of a power MOSFET. CONSTITUTION:For a drive circuit of a power MOSFET 17 using a pulse transformer 15, a resistance 51, the 1st Zener diode 50, a diode 49 and the 2nd Zener diode 48 are connected between the drain and source terminals of the FET 17. Then the rise of voltage between the drain and the source is detected in an overcurrent mode. When this voltage exceeds a set level, the diode 50 has the break to turn on a MOSFET 16 connected to the front stage of the FET 17. Then the potential of the gate of the FET 17 is set at the same level as the source and the FET 17 of the final stage is turned off. Thus an overcurrent state is released. This ensures the high-speed responsiveness and also protects an output element.

Abstract: PURPOSE: To extend the dynamic range of an adder, by applying an output of a digital low-pass filter inputting the output of an adder with opposite polarity, to the adder for a differential pulse code modulation signal and an output signal of a forecasting device.  
     CONSTITUTION: A closed loop is constituted, in which the sum between an input 7 signal from an input terminal 7 and an output of a forecasting device 9 and the difference between the input signal and the output of a digital low-pass filter 14 are obtained at an adder 13 and the output of the adder 13 is inputted to the filter 14 and the device 9. After unnecessary component is rejected by inputting the output of the adder 13 to a low-pass filter 11, the output is outputted to a terminal 12 as an analog output. The DC component produced through the addition of the output of the device 9 and the input signal from the input terminal 7 passes through the lowpass filter 14 and is subtracted at the adder 13 to reject the DC output of the adder 13. Thus, the clipping due to overflow of the adder can be avoided, allowing to extend the dynamic range of the adder substantially.
