    Abstract: PROBLEM TO BE SOLVED: To provide a voltage step-up or step-down switch mode power supply type power converter, capable of independently adjusting each supply voltage of loads, without requiring a plurality of output capacitors.
    SOLUTION: The power converter is shared with a plurality of the loads. The power converter allocates a periodic power-feeding time window, which is exclusive for each load, to each load. Periodicity of the time window is selected corresponding to the remaining time of the load.

    Abstract: PROBLEM TO BE SOLVED: To provide a rectifier circuit having low threshold voltage and under the autonomous control of the MOS transistor.
    SOLUTION: A control circuit for controlling in one polarity a switch with A.C. voltage applied, has a circuit delaying a turn-on of the switch relating to a zero cross of the voltage in both ends of the switch and a circuit which after the turn-on triggers a turn-off of the switch when a prescribed time interval plus or minus error time, controlled by a duty cycle of a preceding one or a plurality of periods of the A.C. voltage in the both ends of the switch, is ended. The control circuit is applicable for forming of the rectifier circuit by the switch.

    Abstract: PROBLEM TO BE SOLVED: To provide a new technique that encrypts in processors data stored in a memory outside the processors, when the data must be used by two or more processors. SOLUTION: When data stored in a memory 23 outside a circuit are encrypted, an encrypted data word Ci related to an initialization vector IVi, and a key identifier KIDi related to a private key Ki having encrypted the data word are stored in the external memory.

    Abstract: PROBLEM TO BE SOLVED: To provide a protected microprocessor equipped with a right allocating system for allocating a lasting access right to a zone of a memory array in the microprocessor, in programs executable by the microprocessor.
    SOLUTION: A right distribution system is provided with a means for imparting to the zone the temporary access right allocated when a subprogram is called out by the one program in the subprograms used commonly by at least the two programs. A library in the protected microprocessor is thereby provided using the library, without disturbing an essence of the right imparted to the program.
