Abstract: PURPOSE:To raise the water permeability of artificial turf in the boundary by providing a water-permeable lower layer base having a higher water permeability than the rest artificial turf for the downside of the artificial turf over a given width from the boundary between soil or natural turf and the artificial turf in an athletic ground. CONSTITUTION:Edge stones 3 are set in the boundary between the ground 1 and a water-permeable artificial turf 2, and the end of the turf 2 is fixed to the side of the stone 3, where a base cloth 5 with piles 4. having water- permeable holes is placed. Large-diameter crushed stones are set with a given width under the turf 2 to form the first water-permeable lower layer base 7 having a given water permeability, and the second water-permeable layer base 8 having a lower water permeability is also formed with a fixed width adjacently to the base 7. In this case, the water permeability of the turf 2 on the base 7 is made higher than the residual turf 2. The water permeability of the turf 2 in the boundary can thus be raised and maintenance can also be easily made.

Abstract: PURPOSE:To detect overload reliably by providing means for detecting excessive output current and insufficient rotational speed of a drive motor for a motor vehicle and detecting overload of the motor based on the logical product of outputs tram both detecting means and then producing an alarm. CONSTITUTION:Current of a motor (not shown) for driving a motor vehicle is determined from a voltage Vs across a shunt resistor 25 and thus determined current is fed to an overcurrent detecting means 1. An open collector type comparator IC compares the voltage VS with a reference voltage Vi set by a variable resistor VR1 and produces an output H when Vs>Vi. An open collector type comparator IC2 in a speed drop detecting means 2 compares a reference value Vf set by a variable resistor VR2 with a voltage Vo obtained by subjecting the output from a rotation sensor 19 to F/V conversion 22 and produces an output H when Vo<Vf. When both comparators IC1, IC2 produce outputs H, a logical product means 3 produces an output H and actuates an alarm generating means 4. According to the constitution, overload is detected reliably in case of continuous steep hill or at the time of motor lock.

Abstract: PURPOSE:To suppress the deterioration in image quality even in the case of increasing the toner capacity of a toner storing part by providing a supporting member which is rotated in the toner storing part and an agitating member which is arranged so as to be freely rotated around the rotational track of the leading end of the supporting member on a carrying and rotating member. CONSTITUTION:As for an agitator 5, the center shaft 6 of the agitator is rotated clockwise in order to supply the toner housed in a hopper 2 to a developing part 1. When the center shaft 6 of the agitator is rotated, a paddle gear 10 engaged with a fixed hopper gear 11 is rotated in the same direction, and the paddle 9 is rotated through the paddle gear 10 and a shaft 8.
