Title: Innovations of Katsuhiko Fukuda
Introduction
Katsuhiko Fukuda is a notable inventor based in Kato, Japan. He has made significant contributions to the field of data recording and reproducing technologies. With a total of five patents to his name, Fukuda's work showcases his expertise and innovative spirit.
Latest Patents
Fukuda's latest patents include a data recording device and a data reproducing apparatus. The data recording device features an interval counter, an α counter, and a segment counter. This invention operates with a clock that maintains a constant frequency, independent of clock information. The interval counter resets upon detecting division information and activates the α counter when it reaches a specific count value. The α counter also resets when division information is detected and increments the segment counter when it reaches a predetermined length. The segment counter outputs a writing inhibition signal when it reaches a count value corresponding to the frame length.
The data reproducing apparatus is designed to avoid the selection of incorrect paths. It includes a branch metric computation unit and multiple parallel computation units. Each parallel computation unit consists of path metric computation units that calculate path metric values based on branch metric values. Path metric memories store these values for subsequent computations, while reliability computation units assess path reliability. Modified-path generating units create an inverted path for any path deemed to have low reliability.
