Abstract: PURPOSE:To obtain a cake with low water content excellent in releasability from filter cloth by adding an inorg. flocculant to org. sludge until the pH of the sludge becomes below a specific value and adjusting the pH of the sludge by an alkali agent before adding an amphoteric high-molecular flocculant. CONSTITUTION:An inorg. flocculant is used for the purpose of adding a metal polyvalent ion to sufficiently neutralize charge and achieving the lowering of the water content of the sludge and the enhancement of the releasability of a cake from filter cloth. However, since sludge showing acidic pH from the beginning like mixed raw sludge of sewage largely lowers in its pH even by the addition of a slight amount of the inorg flocculant, the inorg. flocculant can not be added in an amount capable of sufficiently developing effect in many cases. Then, the inorg. flocculant is added until pH becomes below 4 in order to be capable of sufficiently developing effect and the pH of the sludge is adjusted to 4-7 by an alkali agent before the addition of an amphoteric high- molecular flocculant in order effectively develop the function of the amphoteric high-molecular flocculant.

Filed: 1979-08-02
Abstract: PURPOSE: To efficiently remove an alkali catalyst from a polyether-polyol containing an alkali catalyst, by contacting the polyether-polyol with 'sampi'.  
     CONSTITUTION: The alkali catalyst comtained in a polyether-polyol is removed by contacting the polyether-polyol containing an alkali catalyst with 'sampi' in the presence of water. In this operation, the sampi having the adsorbed alkali catalyst is easily separated from the polyether-polyol within a short time, for example, by filtration, and, in addition, the water added to the system can be removed by the sampi. The term 'sampi' is the generic name of clay minerals having a number of active hydroxyl groups on the surface. A preferred sampi which can be used is one obtained by grinding a digged, raw sampi ore into powder or a particles and drying them. The polyether-polyol which can be used is one obtained by adding an active hydrogen-containing compound to an alkylene oxide in the presence of an alkali catalyst.

Abstract: PURPOSE:To cope with the specification change of a sheet or the like and, at the same time, to detect the flaw of the sheet or the like not only on a cloth inspection machine, but also on a knitting machine and weaving machine. CONSTITUTION:The luminance of a sheet or the like on X-Y coordinates is measured at every position (X1, X2, X3,...) in the width direction of the sheet or the like and a histogram curve 13 is found by plotting the histograms of the measured values T in the width direction of the sheet or the like in the order of the positions (X1, X2, X3,...). Then a standard line 14 which is continuous in the X-axis direction is set on the curve 13 and the flaw 15 of the sheet or the like is detected from the presence/absence of the repeating regularity of the intersections A, B, C,... between the curve 13 and line 14 in the X-axis direction. Since the flaw of the sheet or the like is not found by comparing the image of a standard sheet or the like with a sheet or the like to be inspected, but from the presence/absence of the repeating regularity of the knitting or weaving texture of the sheet to be inspected in the width direction, various kinds of sheets or the like can be inspected without preparing standard sheets or the like or exchanging standard data at every sheet or the like to be inspected.

Abstract: PURPOSE:To form a telecentric f.theta lens which is constituted compactly nd enables high-density recording by composing the lens with five groups of lenses and providing a 3rd or 4th group with an anamorphic lens surface. CONSTITUTION:The 1st group produces large negative distortion to secure f.theta property and the 2nd group compensate a spherical aberration and astigmatism generated by the 1st group to some extent, thereby forming the f.theta lens with a large F value along with the 1st group.

The 4th group is for attaining F value = 3.0 and also compensates a comatic aberration and curvature of field principally. The 5th group secures power betas in a sagittal direction. In addition, the anamorphic lens surface formed in the 3rd and the 4th group suppress the sagittal-side power of the 5th group so that it increases unnecessarily, and compensates sagittal-side astigmatism, i.e. image plane property.
