Latest Patents
One of his latest patents is a timing signal generating circuit. This circuit includes a clock source that generates clock pulses of a predetermined period, a binary counter that divides the frequency of the clock pulses from the clock source by n, and a logical array that decodes the output of the binary counter. The logical array is composed of semiconductor elements and flip-flop circuits, which are set or reset by the outputs of the logical array in response to the clock pulses from the clock source. The outputs of the flip-flop circuits are then used as timing signals.
Another significant patent is a memory device with circulating storage loops. This device features a plurality of recirculating type storage loops, allowing information from the same addresses of the respective storage loops to be read and written in parallel. Additionally, the memory device includes a feature where information indicating whether a corresponding storage loop is a bad or defective loop is written in a specified address of each of the storage loops.
