摘要： PROBLEM TO BE SOLVED: To provide an electrostatic spray gun in which a clearance of an opening between a cylinder member and a cap can be easily and uniformly set over the whole periphery around the path axis and air is uniformly blown from a diffuser to obtain a stable coating pattern. SOLUTION: Pattern air is fed to between a cylinder 4 and a cap 5 through a gas feeding port 14 and is blown radially around the path axis of a gun and to behind the gun from an opening between the pattern air reflecting surface of the cap 5 and the front of the cylinder 4. In this case, since by fitting a projection 21 provided on the outer periphery of the fitting part of the cap 5 in a groove 20 provided on the inner periphery of the fitting part of the cylinder 4, a clearance H between the cylinder 4 and the cap 5 is set over the whole periphery around the path axis, gas is always and uniformly blown from the diffuser to obtain a stable coating pattern.

摘要： PROBLEM TO BE SOLVED: To achieve a more detailed and handy evaluation of an interactive force between particles in a suspension by a method wherein a sample is rotated for a fixed time length to make the particles centrifugally settle and a relationship is determined between the number of revolutions of a centrifugal machine and a filling rate. SOLUTION: When evaluating, for example, a difference in interactive force between particles due to a difference in the pH of the slurry of ceramic particles, easy-to-sinter alumina is used as a material powder. Nitric acid is used as a dispersant to be set by the mol. concentration. Then, firstly, after the adjustment of the slurry, the slurry is made to centrifugally settle using a centrifugal machine. In the measurement of the height 6 of a cake layer 7 after the centrifugal settlement, a test tube 2 having the slurry centrifugally settled therein is put upright to measure the height 6 to the interface of the cake layer 7 and the supernatant layer 8 from the bottom part of the test tube. Then, the height of the cake layer measured after the centrifugal settlement is converted to a filling rate to evaluate. When a difference is noted in the filling rate depending on changes in the number of revolutions, the structural changes of the particles are presumed to affect the filling rate.
