Title: Shunji Usui: Innovator in Audio Reproduction Technology

Introduction

Shunji Usui is a notable inventor based in Fukushima, Japan. He has made significant contributions to the field of audio reproduction technology, holding three patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of his latest patents is a contents data reproducing apparatus. This device continuously reproduces pieces of music without producing a soundless state between music pieces. When a pickup finishes reading a piece of audio data, a microcomputer stops writing the audio data into a storage unit and moves the pickup to the next piece of audio data. The system starts writing the next piece of audio data when the level detection unit indicates that the level is higher than a reference level. An audio data conversion unit then reads the stored audio data and reproduces it.

Another significant patent is an optical disc reproducing apparatus. This apparatus includes a pickup component for detecting digital audio data from an optical disk and a storing component for temporarily holding the detected data. It features an input component for specifying the reproducing direction and speed, along with a control component that manages reading and writing based on these inputs. The signal processing component converts the digital audio data into an analog audio signal for output.
