Abstract: An integrated member can comprise different members each formed of materials having different mechanical characteristics. A method for manufacturing such an integrated member can comprise an electric resistance welding step in which the first member is press-fit into the second member and the press-fit portion can be electrically energized to achieve the electric resistance welding so as to integrate the first member and the second member. The method can further comprise a carburized layer forming step in which carburizing-quenching and tempering, or carbonitriding-quenching and tempering, is performed on the integrated member obtained in the electric resistance welding step to form carburized layers therein in accordance with the mechanical characteristics of the first member and the second member.

Abstract: A rivet setter which can efficiently and smoothly perform the rivet setting operation even when setting rivets each having a shank of its length smaller than a diameter of its head. The rivet setter can be configured to set a rivet sequentially fed one by one from a rivet supplying means by inserting the rivet into apertures formed at predetermined positions on workpieces. The rivet setter can comprise delivery paths for delivering the rivet one by one by forcing the rivet to be slid down to a settable position. The rivet setter can include notches formed on the bottom surfaces of the delivery paths along the rivet delivery direction and extending to the settable position for supporting the head of the rivet in the course of delivery of the rivet on the delivery paths and for hanging the shank of the rivet downward.

Abstract: A rivet setter that can efficiently and smoothly perform, and reduce the takt time for a rivet setting operation. The rivet setter can be configured to set a rivet sequentially fed from a rivet supplying means by inserting the rivet into apertures formed at predetermined positions on workpieces. The rivet setter can have delivery paths for delivering the rivet one by one by sliding the rivet down to a settable position and can have a hanging support portion formed in the settable position in the tip end of the delivery path for supporting the head of rivet and for hanging the rivet shank downward. The rivet setter can be configured to enable the rivet to be set in the apertures of the workpieces by moving the hanging support portion substantially horizontally while keeping the rivet suspended in the hanging support portion and inserted into the apertures of the workpieces.

Abstract: A power transmitting apparatus for a vehicle mounted with a torque converter can be configured to instantly supply sufficient oil to a clutch mechanism on restart of the engine after an idle-stop without an electrically-driven oil pump. A power transmitting apparatus can comprise a torque converter having a torque amplifying function, a clutch mechanism, an oil pump, a clutch control device, an engine control device, and a flow control device. The oil pump can be driven by the driving power of the engine to supply oil to the clutch mechanism and the torque converter to operate them. The flow control device can be configured to limit or prevent the supply of oil to the torque converter by the oil pump and to prioritize the supply of oil to the clutch mechanism when the engine is restarted by the engine control device after the idle-stopped condition.
