Latest Patents

Yoshioka's latest patents include an innovative automatic clock signal phase adjustment system. This system is designed for use with digital magnetic recording and reproducing apparatuses that adopt a partial response class IV coding method. The automatic clock signal phase adjusting circuit features a pattern detection circuit that identifies specific patterns, including '1, 0, -1' and '-1, 0, 1', from a reproduced signal. Additionally, it includes a level detection circuit that assesses the levels of the reproduced signal when the pattern detection circuit detects 0's. The clock reproduction circuit is responsible for reproducing a clock signal from the reproduced signal, while the phase adjustment circuit fine-tunes the phase of the clock signal based on the output from the level detection circuit.
