摘要： A gallic acid alkyl ester or a gallic acid aryl ester is reacted in an inert solvent with 3 equivalents of naphthoquinone-(1,2)-diazido-(2)-sulfonyl chloride in the presence of an alkali to effect sulfonylation of 3 hydroxyl groups in the gallic acid moiety whereby a photodecomposable naphthoquinone-(1,2)-diazido-(2)-sulfonic acid ester is obtained. The new naphthoquinonediazido derivative thus obtained is mixed with an alkali-soluble phenol resin such as m-cresol novolac resin or phenol novolac resin to prepare a positive-type photoresist composition having high sensitivity and high resolving power as well as excellent dimensional accuracy and etching-resistance. In addition, this composition forms a good photosensitive film and can be a good ink receptor.

摘要： The feature of the present invention resides in that when a polyelectrolyte coagulant is added to sludge to dewater the sludge in a sewage treatment plant, the dosage level of the polyelectrolyte coagulant to be to the sludge is controlled most properly, whereby moisture content of dewatered cake can be minimized. This control can be achieved by feeding the coagulant to a sludge feed pipe (3) by means of a coagulant feed pump (6) to carry out a coagulation reaction, dewatering tie sludge by a dewatering means (4), measuring a capillary suction time (CST) of the resultant filtrate (8) by a CST measuring means (10), and then controlling the addition of the coagulant by the coagulant pump (6) so that the filtrate CST value may be minimized
