Title: Memory
Inventor: YOSHINO SUSUMU
IPC: G06F11/22
Filed: 1988-07-15
Abstract: PURPOSE:To efficiently execute the diagnosing processing by operating so as to suppress the sending of an attention signal after a prescribed value set beforehand is reached. CONSTITUTION:At the time of sending an error attention signal to a diagnosing processor 11 by an attention sending control circuit 14, the number of the times of an error is counted by a counter 15, and until the prescribed value is reached by the counted value, the error attention signal is sent and after an arbitrarily settable prescribed value is reached from an external device, the sending of the error attention signal is suppressed. Consequently, when for example, in the memory having 2-bit error detecting and 1-bit error correcting functions, the 1-bit error occurs many times and continuously, the diagnosing processor 11 cannot be cancelled only by the 1-bit error processing. Thus, the diagnosing processing can be efficiently executed.

Title: Highly efficient operating method for pwm regenerative inverter
Inventor: YANAGIYA YOSHIO
IPC: B60M3/06
Filed: 1985-08-12
Abstract: PURPOSE:To keep off any drop in conversion efficiency even in such an acting state as being little in a feeding quantity or a regenerative quantity, by dividing a DC voltage into plural unit inverters in small capacity, controlling it to be a constant voltage, while detecting regenerative or feeding power to be generated in a DC circuit, and converting it into a heteropolar discriminating voltage signal. CONSTITUTION:Divided into plural unit inverters 1-3 in small capacity, a DC voltage is controlled to be a constant voltage V0. This constant voltage is compared with a DC voltage (V) of the inverter and it is converted into a heteropolar discriminating voltage signal capable of discriminating the generation of regenerative power and feeding power by increase or decrease in a transient DC voltage. Motions of each unit inverter is selected and controlled by a voltage signal out of this discriminating voltage signal generator 8 and an AC current detection signal by each of current detectors 21-23 of these unit inverters 1-3. And, according to a feeding quantity and a regenerative quantity, a unit number of these inverters is controlled. Accordingly, in such a state as being little in the feeding power or the regenerative power, a switching loss is reduced so that high conversion efficiency is maintainable.
