Then every time the gain is revised by an addition/subtraction circuit 6, the change in the order of the gain revised before is divided by two, a fraction is rounded off or truncated or rounded by a 1/2 circuit, and the amplitude of the output signal obtained by the gain of the order revised by the number obtained at the 1/2 circuit 7 to the order of the gain before the revision by the command of the amplitude comparison circuit 4 approaches the reference input 5 by addition or subtraction. A gain switching circuit 8revising the control signal controlling the switch so as to select the gain of the order obtained by the addition/subtraction circuit 6 is provided.

Abstract: PROBLEM TO BE SOLVED: To suppress the fluctuation of a prime mover and a generator driven by the prime mover to an allowable value or less by controlling an electric motor for driving a propeller at a torque limit value or less derived from the value based on a power increase allowable value. SOLUTION: A preset power increase allowable value is added to the value obtained by multiplying a torque set value, which is the output of a speed regulator 25 by the detection value of an electric motor 3 by a speed detector 5. The value held by sampling this added value every prescribed time is subtracted by the detection value of the speed detector 5. The subtracted value is set as the torque limit value of the electric motor 3. The deviation between the speed set value and the detection value of the speed detector 5 is arithmetically regulated by the speed regulator 25, and when the resulting regulated arithmetic value exceeds the torque limit value, the torque limit value is outputted as the torque set value, and when it is lower than the torque limit value, the regulated arithmetic value is outputted as the torque set value.

Abstract: PROBLEM TO BE SOLVED: To improve operability when a load of a print job is shared with other image forming devices by transferring image information of an original read with an arbitrary image forming device among plural image forming devices by interrupting the reading of the original, when the remaining memory capacity of any one image forming device is a prescribed value or below.

Here, sets slave inform the master set of the remaining memory capacity of the own sets. Then the master set interrupts the reading of the original, when the master set recognizes that the remaining memory capacity of the master set or any of the slave sets is zero based on the monitor result, that is, when the actual remaining memory capacity is below a prescribed value (10%). The liquid crystal touch panel 31 of the operation display section 30 displays an image, including information which denotes the image forming device whose remaining memory capacity is zero.
