Title: The Innovations of Tsuyoshi Tomita
Introduction
Tsuyoshi Tomita is a notable inventor based in Kasugai, Japan. He has made significant contributions to the field of signal processing, particularly in the context of data storage technologies. With a total of 4 patents to his name, Tomita's work has had a considerable impact on the efficiency and effectiveness of data retrieval systems.
Latest Patents
One of Tomita's latest patents is a signal processor having feedback loop control for a decision feedback equalizer. This innovative signal processor is designed to process an analog read signal that represents data stored on a magnetic disk. It allows for faster read operations without necessitating an increase in circuit area or buffer memory space. The processor includes a decision feedback equalizer that selectively provides a feedback signal added to a read signal during data reproduction from a storage medium. Additionally, it performs error correction by detecting the load of the error correcting process and adjusting the processing speed accordingly.
Another significant patent is a signal processing circuit for preventing pseudo lock of timing recovery PLL. This circuit is utilized in hard disk controllers to quickly synchronize its clock signal with preamble data read from a hard disk. The circuit features a decision feedback equalizer that equalizes a digital read signal based on a clock signal. It includes a timing recovery PLL that generates a clock signal coinciding with the phase of the digital read signal. The design incorporates a first filter, a decision circuit, a shift register, and a feedback filter, all working together to enhance the reliability of data retrieval.
