Abstract: According to the present invention, access to a password area in a nonvolatile memory cannot be granted by simple supply of an address in a normal order. According to one preferable mode, for instance, a trap address is set in the password area so that reading information from the password area is permitted only when the password area is accessed without accessing the trap address, whereas when the password area is accessed the trap address, whereas when the password area is access through the trap address, information reading is inhibited, or meaningless data is output or the information in the password area is destroyed. This invention can make it harder to gain access to a password area which is used to protect against illegitimate copying and can provide a nonvolatile memory having a stronger copy protection capability.

Abstract: The present invention relates to a process for preparing a coal-water slurry comprising the steps of screening coal into a coarse-grained coal and a fine-grained coal; subjecting said coarse-grained coal to gravity classification to classify into a low ash coal, a middle ash coal and a high ash coal; wet grinding a mixture of the fine-grained coal, the middle ash coal and part of the low ash coal, and subjecting same to flotation; preparing a first slurry having a solid concentration of 40-60 wt. % from the low ash froth resultant from flotation; and mixing another part of the low ash coal with this first slurry and wet grinding this mixture. This process can accord the solid concentration of the product slurry with an optional target value by adjusting the amount of the low ash coal mixed with the first slurry, and can use the remaining low ash coal not to be added to the first slurry for the purpose of preparing the second product slurry.

Abstract: A high moisture porous organic solid is dewatered by the steps of (1) heating the high moisture porous organic solid in a fluid medium having an elevated temperature and a high pressure, thereby reducing the moisture of the solid, (2) starting to compress the porous structure of the solid by mechanical means, while maintaining the temperature and the pressure of the surrounding fluid medium the same as in the final stage of step (1), and (3) lowering the pressure of the surrounding fluid medium while maintaining the mechanical compression of the solid, whereby the quality of the porous solid, such as apparent density and calorific values of moist solid per weight as well as per volume are considerably improved.
