  • Patent number: 7708517
    Abstract: A workpiece transfer system or method is provided for transferring workpieces one set of pallets to another set of pallets using a workpiece transfer device that is movably attached to a robot. The workpiece transfer device uses mechanical devices to align the workpiece relative to the robot so that different types of workpieces can be placed into a pallet without the need of troublesome, expensive and complex image processing in which the workpiece holding positions are processed as images by using an imaging device such as a visual sensor. Preferably, the workpiece transfer device cooperates with a positional adjustment part such that the workpiece that is held by the transfer device contacts the the positional adjustment part to position the workpiece in a depthwise direction of the workpiece, a widthwise direction of the workpiece and a longitudinal direction of the workpiece.

  • Patent number: 7698892
    Abstract: An external combustion engine comprises a container (11) with a working liquid (12) sealed therein in a state adapted to flow, a heater (13) for heating and vaporizing the working liquid (12) in the container (11), and a cooler (14) for cooling and liquefying the vapor of the working liquid (12) heated and vaporized by the heater (13). The displacement of the working liquid (12) caused by the vapor volume change is output as mechanical energy by being converted into the mechanical energy. A pressure regulating liquid (18) is sealed in a pressure regulating container (16) communicating with the container (11). A pressure regulating unit (19) regulates the internal pressure (Pt) of the pressure regulating container (16).

  • Patent number: 6849820
    Abstract: A preliminary assembly system for joining a body side panel and a floor panel of an automotive vehicle in a loose-fit hemming joint state by bending a claw piece extending from a main body of one of the panels to hold the other of the panels, prior to welding. The preliminary assembly system comprises a die to be in contact with a back-side surface of the main body of one of the panels in a region forming a loose-fit hemming joint section. Additionally, a main bending blade is provided to be movable to approach the die to bend the claw piece until the loose-fit hemming joint state is established. The main bending blade is moved to approach the die by a movement amount which is mechanically determined relative to a surface of the other of the panels during formation of the loose-fit hemming joint section.
