摘要： A power source apparatus distributes a current command value to be supplied to a load to a plurality of output current amplifiers connected in parallel with the load, and each of the output current amplifiers supplies an output current corresponding to the current command value so distributed. This power source apparatus prevents a circulating current between the output current amplifiers by controlling each output current amplifier so that the difference between the output current from each output current amplifier and the distributed current command value becomes zero, or by inserting current limiting devices into the output line of each output current amplifier.

摘要： A motorcycle of the type having a luggage box in the form of oppositely spaced side cases is organized to reduce the size and weight of the component parts of the vehicle by, according to one aspect of the invention, locating the pivot shaft for the luggage box cover, which attaches the vehicle rear seat, at the front end of the luggage box to reduce the stiffness of the frame parts required to support the cover. Also, the side walls of the side cases are adjustably secured to the vehicle and so configured as to permit selective enlargement of the cases without an attendant increase in aerodynamic drag. The vehicle, further, employs particularly formed side bumpers that are arranged to prevent damage to the laterally extensive side cases of the luggage box in the event of contact between the vehicle and the road surface that would otherwise damage the cowling. Furthermore, the luggage box components are desirably designed to be mounted on a frame structure separate from the vehicle frame but detachably secured thereto in order to facilitate construction and assembly of the vehicle.
