Abstract:
A power unit includes: a differential gear (21) in which a first rotating element (21r) is connected to an output shaft of a prime mover (2), a second rotating element (21s) is connected to a body of rotation of a rotary actuator (3), and a third rotating element (21c) is connected to a driven unit (4) via a first power transmission path (22); a first power transmission system (34, 36, 37) selectively operable between an operating state for enabling power transmission in the first power transmission path (22) and an operating state for disconnecting the power transmission; a second power transmission path (23) connecting between the output shaft of the prime mover (2) and the driven unit (4); and a second power transmission system (32) selectively operable between an operating state for enabling power transmission in the second power transmission path and an operating state for disconnecting the power transmission, wherein an auxiliary device (5) is connected to one of the second rotating element (21s) and the third rotating element (21c) of the differential gear (21).
Abstract:
An accessory drive system which is capable of preventing the driving efficiency thereof from being lowered and achieving simplified construction, and reduction of the size and manufacturing costs. The system has a rotating machine including a first rotor, a second rotor, and a stator. The first rotor is formed by magnetic poles circumferentially arranged, with each two adjacent ones having different polarities. The stator has an armature row for generating a rotating magnetic pole that circumferentially rotates, between the armature and magnetic pole rows. The second rotor is formed by soft magnetic material elements circumferentially arranged with space, and disposed between the magnetic pole and armature rows. A ratio between the number of the armature magnetic poles, that of the magnetic poles, and that of the soft magnetic material elements is set to 1:m:(1+m)/2(m≠1.0).
Abstract:
A power unit includes: an energy dispensing/synthesizing system in which a first body of rotation is connected to an output shaft of a prime mover and a second body of rotation is connected to a driven unit via a first power transmission path; a first power transmission system selectively operable between an operating state for enabling power transmission in the first power transmission path and an operating state for disconnecting the power transmission; a second power transmission path connecting between the output shaft of the prime mover and the driven unit; and a second power transmission system selectively operable between an operating state for enabling power transmission in the second power transmission path and an operating state for disconnecting the power transmission, wherein an auxiliary device is connected to a second body of rotation of the energy dispensing/synthesizing system.
Abstract:
A communication system includes a user terminal connected to a first communication line, a device connected to the first communication line, and storing data to be updated, and a storage apparatus connected to a second communication line and storing the data transmitted from the device. A communication originated at the storage apparatus and addressed to the device and the user terminal is blocked by a firewall apparatus while a communication from the storage apparatus to the user terminal in reply to a request from the user terminal is permitted by the firewall apparatus.
Abstract:
A navigation apparatus comprises a map display control unit that displays a map on a display monitor, a voice information outputting unit that outputs voice information related to traveling of a vehicle, and a highlighting unit that highlights a part of the map that corresponds to the voice information in synchronization with output of the voice information by the voice information outputting unit.
