Abstract: A scanning circuit and an image display device in which the influence of losses in a signal path to scanning wiring and a scanning signal output circuit can be reduced. By considering matrix drive in which one row is driven at a time and two or more of the rows are not simultaneously driven, the 480 rows are divided into six modules and one feedback circuit is provided in correspondence with each module to perform feedback control of the output buffers corresponding to 80 rows. An output from a switch is amplified by an operational amplifier and is input as a compensation signal to all the output buffers by an output voltage compensation circuit. Compensation for a voltage drop is made by using the compensation signal for an increase in voltage such that the apparent voltage drop due to the output current is limited to a small value.

Abstract: The entrapping immobilization pellets satisfy conditions: (A) the deformation rate expressed by (H0?H1)/H0×100 is 70% or more, where the thickness of the pellets before compression is H0 and the thickness of the pellets at the time the pellets are broken by compression is H1; and (B) the particle diameter falls within the range of 0.1 to 1.5 mm. The entrapping immobilization pellets are added to a biological treatment tank having no screen and the entrapping immobilization pellets discharged together with treated water to a solid-liquid separation tank are returned to the biological treatment tank by pumping. With this constitution, the entrapping immobilization pellets are less broken even if they are returned to the biological treatment tank by pumping, a conventional biological treatment tank in which wastewater is treated with activated sludge can be used without modification, and in addition, the particle diameter thereof can be reduced. Therefore, treatment efficiency can be markedly improved.

The driver IC includes a plurality of drive signal output terminals arrange to have variable drive capacities which vary depending on loads of respective signal electrodes of the display device to which the output terminals are connected so as to supply the respective signal electrodes of the display device with drive signal waveforms having identical time constant. The driver IC preferably includes a number of juxtaposed transistors corresponding to but larger in number than the drive signal output terminals, wherein the respective drive signal output terminals are connected to prescribed numbers of transistors so as to have different drive capacities depending on loads of the signal electrodes of the display device to which the output terminals are connected.

Abstract: A drive signal generation circuit which performs gradation control on a load by a drive signal having a stepped waveform. In a case where the wave height value corresponding to input gradation data is Vm (2?m?n), the drive signal is caused to rise in such a manner that each output Vk (2?k?m) is produced one slot after the output V(k?1) to increase the wave height value V0 (reference potential) to Vm in a stepping manner. One slot corresponds to a unit time of the pulse width modulation. The drive signal is caused to fall in such a manner that each output V(k?1) (1?k?m?1) is produced one or two slots after the output Vk to reduce the wave height value from Vm to off level in a stepping manner. A delay circuit is used to delay signals slot by slot. A selection is made from delayed signals according to luminance data to determine a waveform. The circuit is also designed to enable the drive signal waveform rise position to be changed.
