    摘要: A stereophonic apparatus uses three speakers respectively installed toward a front of a vehicle on both shoulders of a seat back of a driver's seat and toward a back of the vehicle on an exact center in front of a driver. This configuration provides more effectively exerted positioning effects for a virtual sound source realized by using the three speakers, especially for the effects in a frontward field of sound.

    摘要: A process for manufacturing a carbon fiber or graphite fiber includes melt-spinning a carbonaceous pitch, infusibilizing the resulting pitch fiber, carbonizing, and when necessary graphitizing the fiber. A precursor of the carbonaceous pitch is centrifuged in a molten state to separate the precursor pitch simultaneously into a solids slurry layer, an optically isotropic phase, and an optically anisotropic phase, and the latter is utilized as the carbonaceous pitch.
