    摘要： A semiconductor integrated circuit device with a copy-preventive function comprises a memory for storing data to be used by users, an input unit for performing various logical operations on at least one input information fed externally and accessing the memory, an output unit for performing various logical operations on the data at the time of supplying the data from the memory, a judging unit for comparing at least one of the state of the input information, the logical state of the input unit, the logical state of the output unit, and the state of data provided by the output unit with specific judgment information and indicating the result of comparison, and a control unit that when the result indicated by the judging unit reveals that the at least one of the states is consistent with a specific state, acts at least on the output unit so as to prevent data stored in the memory from being supplied normally. Due to this configuration, a copy-preventive function can be reformed frequently from both the aspects of software and hardware. Consequently, illegal copying of data can be substantially disabled.

    摘要： The present invention provides a power flame retardant for a halogen-containing vinyl resin, which comprises the following Components A, B and C. (A) 5 to 30 parts by weight of at least one of alkali metal compound of lithium, sodium and potassium calculated as the formula M.sub.2 O where M is an alkali metal; (B) 0.2 to 10 parts by weight of a perchloric acid radical in the form of the acid or a salt or amine thereof, calculated as perchloric acid radical; and (C) 1 to 50 parts by weight of a hydrophobic dispersing agent having a boiling point or a decomposition temperature of 200.degree. C. or higher. All the parts by weight are based on 100 parts by weight of antimony pentoxide (Sb.sub.2 O.sub.5). The flame retardant of the present invention does not impair transparency of the halogen-containing vinyl resin, and also does not worsen various physical properties such as thermal stability and weathering resistance. The invention also provides (1) flame retardant halogen containing resins and (2) a process for preparing the powdered flame retardant.
