摘要： PROBLEM TO BE SOLVED: To obtain an aqueous cutting fluid excellent in disperse stability and viscosity stability of abrasive grains and especially effective for wire saws and an aqueous cutting fluid usable therefor and provide a method for cutting hard and brittle materials excellent in processing accuracy, washing property, etc., of material to be cut. SOLUTION: This cutting fluid comprises a cationic water-soluble resin having 20-200 mg KOH/g amine value and at least one or more kinds of viscosity adjusters selected from inorganic and organic bentonite and aqueous silica sol and has nonvolatile substance content of the viscosity adjuster in an amount of 0.1-30 wt.% based on nonvolatile substance content of the cationic water-soluble resin. This method for cutting crustaceous materials comprises cutting hard and brittle materials with a cutter by using an aqueous cutting fluid obtained by adding abrasive grains to the above aqueous cutting fluid so that the content of the abrasive grains becomes 100-1,000 wt.% based on the nonvolatile substance content of the aqueous cutting fluid.

摘要： PROBLEM TO BE SOLVED: To provide a working fluid for cutting which exhibits a small change in viscosity even when recycled and is excellent in thixotropic properties, working accuracy, handleability, capability for cleaning cutting scraps, abrasive grain dispersion, etc., by compounding a polyalkylene glycol (deriv.) with a viscosity improver and water. SOLUTION: This working fluid is prepd. by compounding 90-99.998 wt.% at least one glycol compd. having an average mol.wt. of 300-1,000 and selected from among polyalkylene glycols (or their derivs.) and glycol compds. represented by the formula (R1 and R2 are each 1-4C alkyl, 2-5C acyl, or H; and n is 5-22) with 0.001-5 wt.% viscosity improver selected from among polyacrylic acid, polyacrylamide, methylcellulose, ethylcellulose, carboxymethylcellulose, hydroxypropylcellulose, high-molecular polysaccharides, and montmorillonite compds. and 0.001-5 wt.% water. The working fluid is compounded with 20-80 wt.% abrasive grain to give a comps. for cutting.

摘要： PROBLEM TO BE SOLVED: To always form good images in any copying environment over a very long period of time without causing a filming due to toner fusion to a photoreceptor or flawing the photoreceptor even after copying on many sheets, in an image forming method in which an electrostatic charge image on an inorganic photoreceptor is developed with an electrostatic charge image developer, a formed toner image is transferred, and the photoreceptor is cleaned with a cleaning blade. SOLUTION: An electrostatic latent image on an inorganic photoreceptor 1 is developed with the electrostatic charge image developer 6 having an average primary particle diameter of 0.2-1.5 μm and a specific surface area of 10-50 m 2 /g, and containing 0.1-5.0 wt.% fine silicon carbide powder in which the amount of agglomerated particles is 10-60%, based on the amount of toner particles, the developed image is transferred to a transfer material 11, and the residual toner remaining on the photoreceptor is scraped off with a cleaning blade 9.

摘要： PROBLEM TO BE SOLVED: To recover those of abrasive grains and working fluid at each specified grain size by carrying out a classifying process in regard to the solid phase separated from a spent cutting composition, and separating it to plural liquid phases containing abrasive grains of the specified grain size. SOLUTION: First of all, a secured spent composition is separated into the solid phase, where abrasive grains are settled, and the liquid phase or working fluid. With the secured solid phase stirred up, the abrasive grains are uniformly dispersed around, and thereby stock slurry is prepared. This stock slurry is charged into a cylindrical classifying tank (a) whose lower part is formed into being conically shaped, and then a constant flow rate of water is stably fed out of a water supply port a1 at a lower part of this classifying tank (a). At this time, those of unrefined abrasive grains by cutting work are left behind in the classifying tank (a). The slurry containing the yet smaller abrasive grains and unnecessaries is overflowed from an upper distributing water port a2 of the classifying tank (a), and it comes into another classifying tank (b) from a slurry supply port b1 at a lower part of this classifying tank (b). Likewise, hereafter, even those of classifying tanks (b) and (c) collect the liquid phase containing abrasive grains of the specified grain size respectively.
