Abstract: PROBLEM TO BE SOLVED: To provide a non-volatile semiconductor memory device which can reduce write-in and verification read-out time, and the data write-in method for the device. SOLUTION: After the all bit line voltage is charged to a power source voltage VCC before writing, the bit line is discharged through NMOS transistors NT25, NT26, in which a gate electrode is connected to the second storage node N21b, N22b of a latch circuit Q21, Q22, thereby charging the bit line at high speed; and by making the bit line voltage, which is connected to a write-inhibit voltage, the power source voltage VCC, the threshold voltage Vth of a selective gate on the drain side is lowered, with a margin given to a self- boost, and also with writing performed parallelly. Consequently, the bit line charging time is reduced before writing of data, resulting in the reduction of the entire write time, and enabling verification read-out and normal read-out to be carried out at high speed.

Abstract: PROBLEM TO BE SOLVED: To provide a distribution line monitoring and controlling device, provided with a voltage-adjusting function which controls the voltage of a distribution line to keep it at an appropriate value. SOLUTION: The data of current and power factor of a high-voltage distribution line 1 are received, outputted to a data-measuring means 82, and converted to be stored in a measured data file 87. A section voltage calculating means 83 calculates each section voltage of the distribution line 1 from the measured data file 87 and a distribution system facility data file 88. A section voltage presuming means 86 determines whether or not each section voltage obtained by the section voltage calculating means 83 is within a tolerable value. If it is outside of the tolerable value, parallel capacitors SC provided in each section are switched on and off to presume the section voltage of each section. A controlled SC determining means 85 determines the SC to be controlled, based on the data of the switched-on SC in systems, where each section voltage is all within the tolerable value.  An SC-controlling means 84 outputs the on-off control of the controlled SC to a remotely-controlled data receiving and transmitting means 81 and then to a remote controlling device 53, which transmits it to a distribution remote controlling device 52 as the on-off data for SC controlled substation to perform it.
