Latest Patents

Fukatsu's latest patents include a scanning method for disk players and an automatic sound volume control device. The scanning method for disk players allows for high-speed reproduction of video data from a recording disk. This method executes a sequence of track jump operations, enabling the data detection point of the pickup to jump across tracks of the disk. This is alternated with intervals of play operation, during which data is read from the disk. The data obtained is written into memory and repetitively read out to produce a clear output video signal, resulting in a display image free from noise and disorder during scanning operations.

The automatic sound volume control device is designed for use in devices such as radios or tape players in high ambient noise environments. It detects noise and sound signal levels above predetermined reference levels and produces a control signal based on these output signals. This control signal determines the amplification gain of the sound signal. Several methods for producing the control signal are described, each offering unique advantages for different situations and types of reproduced sound.
