    摘要： A power transfer device of the type which includes a housing, a first shaft rotatably mounted within the housing to transfer drive torque from a power transmission to a set of rear-wheel drive axles, a second shaft rotatably mounted within the housing in parallel with the first shaft for drive connection to a set of front-wheel drive axles, and a pair of clutch sleeves mounted on the first and second shafts and shiftable between respective positions in which they effect drive connection or disconnection between the first and second shafts. A shift mechanism for the clutch sleeves includes a shift rod arranged in parallel with the first and second shafts and axially movably mounted within the housing, a first shift fork axially slidably mounted on the shift rod and coupled with one of the clutch sleeves, a second shift fork fixedly mounted on the shift rod at a position adjacent the first shift fork and coupled with the other clutch sleeve, and a retainer element fixed to the shift rod at a position where it is spaced in a predetermined distance from the first shift fork when the second shift fork is maintained in engagement with the first shift fork.

    摘要： With regard to an optical communications system, in a system using a single optical fiber cable between subscribers and an exchange and in which bi-directional transmission is performed using the same 1.3-.mu.m wavelength, the exchange-to-subscriber signal is a high-speed, wideband signal which is bandwidth limited by means of a lowpass filter, and the subscriber-to-exchange signal is a carrier having a frequency higher than the upper limit of the exchange-to-subscriber signal and which is modulated with a low-speed, narrowband signal.
