Filed: 1988-04-06
Abstract: PURPOSE:To prevent a model from its unstable action due to a circuit delay by giving an instruction value to a sinusoidal wave generating circuit considering its delay and an amplifier in its delay. CONSTITUTION:First, terminal voltage of a generator and its current are read through an input device 3. Next being based on this read value, the generator calculates its internal voltage and current by a Park's equation or the like. While the equation of motion is solved. By these calculation, voltage amplitude, phase and a frequency of the generator in the next step are calculated and output to a sinusoidal wave generating circuit 4 through an output device 2. Here a preset circuit adds its delay to be output. By the method thus obtained, a simulation circuit eliminates its delay, even when a large disturbance is analyzed, unstable action is prevented.

Abstract: PURPOSE:To put on a video light when low light quantity is supplied to a subject by performing the photoelectric conversion of light quantity in photography by a phototransistor, and putting on the light when it shows a value less than a threshold value. CONSTITUTION:When no light over the threshold value is made incident on the phototransistor 30 i.e., the light quantity shows the one less than the threshold value, the output of a NAND gate 26 goes to H. The output turns on a transistor(TR) 35 by supplying a current to the base of it via a resistor 33 and a capacitor 34. Accordingly, a TR 36 is turned on, and a TR 42 is turned on, and as a result, the light 28 is put on. Simultaneously, when the TR 36 is turned on and when a voltage over a Zener voltage is applied to both terminals of a Zener diode 40, the diode 40 is energized. Therefore, since the current is supplied to the base of the TR 35 via the diode 40 and a resistor 39, the light 28 is continued to put on. Also, when the light quantity over the threshold value is made incident on the TR 30, the gate 26 goes to L, and the TRs 35, 36, and 42 are turned off, and the light 28 is put off.
