摘要： By respectively abutting first and second outer diameter sections of a second metallic member against first and second inner diameter sections of a first metallic member, and energizing the first metallic member and the second metallic member using a pair of electrodes while pressurizing both metallic members in an axial direction thereof, a first junction where the first inner diameter section and the first outer diameter section are bonded and a second junction where the second inner diameter section and the second outer diameter section are bonded are formed between both metallic members, and a gap in which the metals do not come into contact with each other is formed between both junctions over a predetermined axial length. Accordingly, a high joint strength can be secured using less energy for bonding.

摘要： A hybrid construction machine drives the upper swing structure using a hydraulic motor and an electric motor together and is capable of regenerating the energy of the upper swing structure in deceleration or stopping into electric power and using the regenerated electric power for assisting the hydraulic motor for driving the upper swing structure. The opening area characteristics of a meter-out restrictor and a bleed-off restrictor of a swing directional control valve are set to become larger than for construction machines driving the upper swing structure with the hydraulic motor alone. Torque of the electric motor is controlled so that the total sum of the actual torque occurring in the hydraulic and electric motors in deceleration or acceleration of the hydraulic motor equals the torque occurring when the opening area of the meter-out restrictor or the bleed-off restrictor is set at the prescribed opening area.
