A file system (i) permits storage capacity to be added easily, (ii) can be expanded beyond a given unit, (iii) is easy to administer and manage, (iv) permits data sharing, and (v) is able to perform effectively with very large storage capacity and client loads. State information from a newly added unit is communicated (e.g., automatically and transparently) to central administration and management operations. Configuration and control information from such operations is communicated (e.g., automatically) back down to the newly added units, as well as existing units. In this way, a file system can span both local storage devices (like disk drives) and networked computational devices transparently to clients. Such state and configuration and control information can include globally managed segments as the building blocks of the file system, and a fixed mapping of globally unique file identifiers (e.g., Inode numbers) and/or ranges thereof, to such segments.

The invention discloses a low segregation centrifugal casting high speed steel roll and the method. The roll is constituted by high speed steel roll body and alloy ductile ion roll core. The roll is produced by electric furnace. The high speed steel roll body is cast on horizontal centrifuge. As the liquid steel is cast iron powder suspension concentrate with 4%-6% by weight of liquid steel is added. After the liquid steel is cast glass waste sludge is added and then it is cooled by spraying water to form the model. Meanwhile the rotate speed of casting model is changed continuously and finally the ductile ion roll core is cast at the top statically. There is no obvious element segregation in radial section of high speed steel roll manufactured in invention. The macro hardness of roll is high and can achieve 63-65HRC. The difference of roll face hardness is less than 2HRC. The hardness fall of roll along the radial direction is small. The tensile strength of roll body is more than 600MPa and the elongation of roll core is more than 3%. The service life is improved by 5-8 times than high chromium cast iron roll and is improved by 35%-48% than common high speed steel roll. It can decrease the producing cost of rolling steel and prolong roll changing period.

A new and novel device for controlling a steering characteristic of a vehicle such as automobile so as to enhance an effect of suppressing a change in a behavior of the vehicle body due to a difference between driving and braking forces on the left and right wheels is characterized in that the device makes an amount of controlling the steering characteristic smaller as an index indicating an amount of a shift of vertical loads between the left and right wheels is increased. The steering characteristic is modified through controlling steering assist torque or a steering angle of the steered wheels. The steering assist by the steering control device is fully effective when the vehicle is running on a straight road having surfaces of different frictional coefficients while less effective on a curved road having a uniform frictional surface, preventing undesirable and unexpected modification of the steering characteristic during turning of the vehicle.
