The continuous multiple arc type wave-absorbing bank comprises a main body and a slope protector, wherein the upstream surface of the main body is provided with an inclined slope, and the slope protector comprises a circular-arc protecting surface and a horizontal connecting section.

The feedback control includes a video camera focused on sludge as it trails behind plows on a dewatering belt, a video image processing system for converting the video signal into single numbers known as “camera readings”, and a computer programmed both to compare them with a “camera reading” setpoint and to determine whether the filtrate charge is more positive or more negative than it normally is whenever the “camera reading” deviates from its setpoint by a threshold amount. A controller, activated by the computer, incrementally resets the polymer feedrate in such a direction as to restore the normal cationic charge of the filtrate. The feedback control uses the streaming current value measured immediately after each “camera reading” excursion to update the streaming current setpoint.

When a potential of a power supply line varies according to a flowing current, the gate-source voltage Vgs of a transistor also varies, leading to variations in the constant current between each source follower. In order to solve this problem, a potential Vb of the gate terminal of a transistor as a constant current source is changed in the same manner as a power supply line Vss which is connected to the source terminal of the transistor. Therefore, variations in the constant current are suppressed and variations in the output of the source followers are thus suppressed. In addition, by connecting the circuit having source followers to the output side of a signal line driver circuit, it can be prevented that luminance unevenness of a striped pattern is recognized in a display portion of a semiconductor device.
