摘要： PROBLEM TO BE SOLVED: To control actuation of an electromagnetic clutch so as to smoothly drive a driven shaft to reach a predetermined set revolutions in a short time, without wearing the electromagnetic clutch during a high speed rotation of a driving shaft. SOLUTION: A power supply amount and a power supply time for actuating the electromagnetic clutch 19 are controlled by a power supply control means 22. When a switch 21 is turned ON, the power supply control means 22 supplies, for a short time t1, power required for making the electromagnetic clutch 19 to be in a fully connecting state, and supplies power required for making the electromagnetic clutch 19 to be in a partial clutch engagement state for a predetermined time t2 in which wear of the electromagnetic clutch 19 does not generates. Thereafter, the power supply control means 22 supplies power required for making the electromagnetic clutch 19 to be in the fully connecting state again.

摘要： PROBLEM TO BE SOLVED: To provide a liquid spray device capable of constantly attaining uniform spray without being affected by the change of the number of liquid discharge nozzles for discharging a liquid and the change of a machine moving speed. SOLUTION: The flow rate of the liquid in a diversion pipe line 10 is detected by a flow rate sensor 14. The diversion pipe line 10 is communicated with a discharge port 5 side of a pump 2 and allows liquid discharge quantities from respective nozzles (n) forming spray nozzle groups N to be passed at a constant rate of the liquid L. In a control device 16, the flow rate of the liquid necessary for attaining the required spray quantity per unit area in the diversion pipe line 10 is calculated based on the signals from a velocity sensor 15 and the flow rate sensor 14 and the discharge quantity of the pump 2 is controlled to realize the calculation result.
