A stainless steel sheet for fuel cell separators comprises a predetermined chemical composition, wherein the stainless steel sheet has a textured structure at a surface thereof, an average interval between projected parts of the textured structure being 20 nm or more and 200 nm or less, and a ratio [Cr]/[Fe] of an atomic concentration of Cr existing in chemical form other than metal to an atomic concentration of Fe existing in chemical form other than metal at the surface of the stainless steel sheet is 2.0 or more.

A hub main body (13z) is supported by a support portion (18). At least one block (22) is engaged with a stationary flange (6) of an outer ring (2). As a support plate (21) rotates, the outer ring (2) rotates. A caulking portion (16) is formed by pressing a pressing die (20) on a cylindrical portion (31).

Systems, methods and apparatus for automated vehicle wheel removal and replacement are provided. One system includes a computer system with applications for scheduling the replacement of tires for the vehicle. An electronically controlled lift device and robotic apparatus is configured for interaction with the computer system. The lift device mechanically adjusts arms for placement on lift points of vehicles. The robotic apparatus detects positioning of lug nut configuration for a wheel, removes lug nuts, and then removes the wheel from the wheel hub with gripping arms. The wheel and tire are then handed off to a separate tire changing machine. When a new tire is replaced the robotic apparatus then mounts the wheel to the original wheel hub, and then secures the lug nuts to the lug nut bolts.

A surgical instrument for use with a robotic manipulator includes an end effector assembly having one or two end effector members, each having a distal treatment end, a proximal end, and a tendon pass-through. Tendons that provide both mechanical actuation and electrical conduction to the end effector members are positioned in the pass-throughs.
