| PURPOSE:To stably control the particle diameter of product crystal by preventing the oscillation and non-linearity of the crystallization phenomenon in a salt-forming process. CONSTITUTION:The characteristics of a crystallizing apparatus (a) exhibiting oscillation property and nonlinearity in a crystallization system 20 of a salt- forming process are modeled by a model-constructing function part 11 using a learning function of a neural net based on a measurement data on product crystal particle diameter having distribution. The crystallization factors to get target values are inferred from the target product crystal particle diameter based on the constructed model. In the case of varying operation state, the crystallization operation conditions for getting the target average crystal particle diameter are inferred on the crystallization factors other than the factors to cause the variation of the operation state. The inference is carried out by judging the effective range based on the maximum value, the representative mean value and the minimum value of the product crystal particle diameter. | ||||||

| 8 | Method for the preparation of pellets of metal halide | EP93116467.7 | 1993-10-12 | EP0592998A1 | 1994-04-20 | Wataya, Kazuhiro; Sakai, Shigeru; Fukuda, Masahiko; Yoshida Norifumi |
An improvement is obtained in the method for the preparation of pellets of a metal halide as a light-emitting source of metal halide lamps, of which an extremely low moisture content is essential, in order not to increase the moisture content of the metal halide during pulverization and compression molding of the metal halide. Thus, a metal halide dehumidified in advance to have a moisture content not exceeding 5 ppm is pulverized and compression-molded in an atmosphere of an inert gas of which the dew point is -60 °C or lower so that substantially no moisture absorption takes place during processing. |
