  • Patent number: 8888636
    Abstract: A power output apparatus 1 to 1D including an engine 6, a motor 7, and a transmission 20 to 20D having two transmission shafts connected to the engine 6 is provided. The transmission includes a power combination mechanism 30 adapted so as to be able to rotate first to third elements differentially from each other. The first element is connected to any one of the two transmission shafts, the second element is connected to a driving shaft 9 or 9, and the third element is connected to the motor 7. The second element combines the power transmitted from the first element and the power transmitted from the third element, and transmits the combined power to the driving shaft 9 and 9. The other transmission shaft of the two transmission shafts transmits power to the driving shaft 9 or 9 without going via the power combination mechanism 30.

  • Patent number: 5301788
    Abstract: A pallet with a workpiece mounted thereon is delivered on a pallet carriage, and transferred onto the table of a machine tool which has a different height from the pallet carriage. Lifting mechanisms on the pallet carriage are engaged by respective positioning members in front of the machine tool. The lifting mechanisms are actuated to lift the pallet carriage to position the pallet carriage for transfer of the pallet onto the machine tool table. The pallet is transferred from the pallet carriage onto the machine tool table, half of a predetermined stroke by a first transfer mechanism on the pallet carriage and the remaining half of the stroke by a second transfer mechanism on the machine tool table. The table has vertically movable support rollers for supporting the pallet when it is transferred onto and from the table.
