Collaborative management of shared resources is implemented by a storage server receiving, from a first resource manager, notification of a violation for a service provided by the storage server or device coupled to the storage server. The mode of operation of a subcircuit in the memory can be controlled on the basis of the stored frequency-range information item in the register. The drive portion includes a plurality of drive elements that each are capable of expanding or contracting in response to an applied electric signal so as to provide different drive outputs to the joint portion.
