Abstract: PURPOSE:To stabilize an operation without necessity of a complicated process by precharging a bit line to the same potential as a power source voltage through a conductivity type transistor, and further clamping the potential of the bit line to a lower voltage corresponding to a threshold voltage of the transistor. CONSTITUTION:Bit line pairs 3 are so precharged to a power source voltage 20 by an equalizer having P-type MOS transistors 2a, 2b, 2c as not to conduct an operation of a source follower. On the other hand, a clamping circuit having N-type MOS transistors 1a, 1b is so controlled by an FF 18 for controlling it by an identification signal WE8 as to conduct the operation of the source follower to clamp the pair 3 from when it becomes a potential lower by threshold voltages of the 1a and 1b than the voltage 20. A potential difference of the pair 3 is amplified by a vibration amplifier 4 to be output to a data line 14. Thus, a difference between a clamping potential and a precharging potential for deciding the amplitude of the pair is decided by the threshold voltage of the transistors.

Title: Three-phase balancing equipment
Inventor: YOSHIDA TOSHIO
IPC: G05F1/10
Filed: 1987-10-05
Abstract: PURPOSE:To make each phase current into balanced currents, even if a load is in an unbalanced state, by taking in each phase current from an AC power according to the difference between each phase load current mean value and each phase load current. CONSTITUTION:When a load 2 is in an unbalanced state, the current values of AC buses U, V, W on the load side indicates values differing from each other. Then, a mean value is obtained by an average operation circuit 10 and the deviation between said mean value and each phase current is operated by an adder-subtractor circuit 11. Accordingly, when the deviation value is small, a forward power converter 3 is PWM(pulse width modulation)-controlled on the basis of said value and a corresponding current is taken in from an insufficient phase and converted into DC. Also, when the deviation value is large, a reverse power converter 5 is PWM-controlled, the corresponding current value converted into DC previously is converted into AC, and each electric current with a current value corresponding to an overcurrent value is released to the bus of said overcurrent value on the load 2 side via an insulating transformer 6.
