Latest Patents

**Economical Recording and Reproducing Apparatus Which Performs Real-Time Processing.** This invention describes an audio recording and playback apparatus designed to process signals in real time using a low-cost structure. It converts incoming audio signals into digital data and records that data across clusters on a storage medium. File-management and directory information identify the clusters and their playback order, while reproduction-procedure information specifies the starting cluster for a file. During playback, the apparatus reads the stored data and converts it into output audio signals.

**Sprocket Wheel for Advancing Film and Device for Advancing Film Using It.** This invention uses sprocket wheels with three pairs of teeth, spaced 120 degrees apart, to engage film perforations. A cam, follower, lever, and registration pins coordinate the film’s movement and positioning. A switching lever can place the mechanism in a position that prevents the shaft from rotating, even when the main shaft turns.

Career Highlights

Tsukada’s listed career includes work at TEAC Corporation and Imagica Corp. The two patents reflect applications in distinct technical areas: digital audio equipment and film-transport mechanisms.
