Abstract: The number of digital-analog converters is decreased in an audio processing apparatus that outputs an audio signal to not only a device disposed in a main room but also a device disposed in a sub-room. The audio processing apparatus includes a digital-analog conversion unit for outputting an extended left audio signal and an extended right audio signal in an analog format, or for outputting a sub-room left audio signal and a sub-room right audio signal in the analog format; and an input switch unit that switches between a supply of a combination of the extended left audio signal and the extended right audio signal to the digital-analog conversion unit and a supply of a combination of the sub-room left audio signal and the sub-room right audio signal to the digital-analog conversion unit.

Abstract: A power transfer system which distributes a power of the engine to front and rear wheels in a vehicle. The power transfer system comprises a first input shaft whose one end portion is in butt connection with an input shaft from an engine and whose other end portion is supported to a ball bearing fixed to a housing. A friction clutch is installed to the first input shaft such that the power to the first output shaft is transferred to a second output shaft through an endless chain according to the engagement of the friction clutch. A ring groove is formed at an outer peripheral portion of the first output shaft, and a ring member is installed to the ring groove so as to be in contact with a side surface of the ball bearing. Therefore, a thrust load applied to the first output shaft due to the operation of the friction clutch is securely received by the ball bearing through the ring member.
