A data processing system having flexibility coping with parallelism of a program comprises a plurality of processor elements for executing instructions, a main memory shared by the plurality of processor elements, and a plurality of parallel operation control facilities for enabling the plurality of processor elements to operate in synchronism. The plurality of parallel operation control facilities are provided in correspondence to the plurality of processor elements, respectively. The data processing system further comprises a multiprocessor operation control facility for enabling the plurality of processor elements to operate independently, and a flag for holding a value indicating which of the parallel operation mode or the multiprocessor mode is to be activated. The shared cache memory is implemented in a blank instruction and controlled by a cache controller so that inconsistency of the data stored in the cache memory is eliminated.

In a heating roller, electrode members come in contact with power supplying members for supplying power to a heating element. The electrode members are resiliently fitted to the heating element. Power is supplied from the power supplying members to the heating element through the electrode members. In this heating roller, it is possible to solve problems about cracks, etc. caused by thermal expansion, etc. of each of the heating element, the electrode members and an electric conductor formed by materials having different coefficients of thermal expansion. Accordingly, reliability of the heating roller is high and the heating roller is safe. The heating roller may have a bearing for rotatably supporting the heating roller; a structural member for supporting the bearing; and a rotating force transmitting member arranged in an electrode member resiliently fitted to the heating element or arranged in a conductive resilient member between the heating element and the electrode member so that rotating force of the heating roller is obtained from the exterior thereof.

A battery state estimating unit estimates an internal state of a secondary battery in accordance with a battery model equation in every arithmetic cycle, and estimates a charging rate and a battery current based on a result of the estimation. A parameter estimating unit obtains a battery current measured by a sensor as well as the charging rate and the battery current estimated by the battery state estimating unit. The parameter estimating unit estimates a capacity deterioration parameter such that a rate of change in difference (estimation error) between a summed value of an actual current and a summed value of an estimated current with respect to the charging rate is minimized. A result obtained by estimating the capacity deterioration parameter is reflected in the battery model by the battery state estimating unit.

摘要:
A diffusion estimation unit follows a diffusion equation in an active material that is represented by a polar coordinate to estimate a distribution in concentration of lithium in the active material. An open circuit voltage estimation unit obtains an open circuit voltage in accordance with a local SOC(θ) based on a concentration of lithium obtained at an interface of the active material as estimated by the diffusion estimation unit. A current estimation unit uses a battery's voltage measured by a voltage sensor, the estimated open circuit voltage, and a parameter value that is set for the battery by a battery parameter value setting unit, and follows a voltage-current relationship model expression simplified from an electrochemical reaction expression to estimate the battery's current density. A boundary condition setting unit sequentially sets a boundary condition for the diffusion equation of the diffusion estimation unit for the active material's interface, as based on the battery's estimated current density. Thus a battery model that allows an internal state to be estimated based on an electrochemical reaction dynamically and can also achieve an alleviated operating load can be used to estimate a state of a secondary battery.
