It is a task of the invention to make it possible to calculate a control target value of one actuator or control target values of a plurality of actuators regarding engine control at a high speed through the use of a multicore processor. With a view to accomplishing this task, a plurality of lattice points that are arranged on a two-dimensional orthogonal coordinate system having axes representing a first operating condition and a second operating condition respectively are associated respectively with at least one or some of a plurality of cores that are arranged in a latticed manner on the multicore processor on one-on-one level on a same line as on the two-dimensional orthogonal coordinate system, and a calculation program for calculating an optimal control value at the associated lattice point or calculation programs for calculating optimal control values at the associated lattice points are allocated respectively to at least one or some of the plurality of the cores. In addition, each of the cores with which the lattice points are associated respectively is programmed, in a case where an operation area on the two-dimensional orthogonal coordinate system to which a current operating point belongs is an area that is defined by the lattice point associated with each of the cores itself, to transmit, to an interpolation calculation core, an optimal control value at the relevant lattice point that is calculated by each of the cores itself. The interpolation calculation core is programmed to perform an interpolation calculation of an optimal control value at the current operating point using optimal control values at all the lattice points that define the operation area on the two-dimensional orthogonal coordinate system to which the current operating point belongs. In addition, the multicore processor outputs the optimal control value at the current operating point, which is obtained from the interpolation calculation core, as a control target value of each of the actuators.

A control device for a multi-cylinder internal combustion engine that is equipped with a variable compression ratio mechanism includes an air-fuel ratio sensor, and a controller that determines whether or not actual mechanical compression ratios in cylinders of the internal combustion engine are uniform. The controller controls the variable compression ratio mechanism by decreasing a target mechanical compression ratio from a current first target mechanical compression ratio to a second target mechanical compression ratio without changing the amount of intake air and a fuel injection amount, and determines that the actual mechanical compression ratios in the cylinders are not uniform when the target mechanical compression ratio is set at the first target mechanical compression ratio if the differences in the output air-fuel ratios from the air-fuel ratio sensor for exhaust gases from the cylinders before and after the control of the variable compression ratio mechanism are not uniform.

The invention is a process for producing a rubber composition containing at least one rubber component (A) selected from natural rubbers and synthetic diene rubbers, a filler containing an inorganic filler (B), a silane coupling agent (C) and a vulcanization accelerator (D), wherein the rubber composition is kneaded in multiple stages, the rubber component (A), all or a portion of the inorganic filler (B), all or a portion of the silane coupling agent (C) and the vulcanization accelerator (D) are added and kneaded in the first stage of kneading, and the specific energy for kneading in the first stage is from 0.05 to 1.50 kWh/kg. The specific energy is obtained by dividing the power consumption by the motor in the kneading device in the first stage of kneading by the total mass of the rubber composition therein.

A brake system provided with a brake booster using intake negative pressure of an engine for boosting a brake operating force for a vehicle. A requested braking force is detected base on an operating amount of a brake pedal, and when the requested braking force is less than a threshold value, a master cylinder pressure prevailing in the master cylinder using an operating force boosted by the brake booster is supplied to the wheel cylinder. On the other hand, when the requested braking force is greater than or equal to the threshold value, brake fluid pressure having been boosted by a pump is supplied to the wheel cylinder. The threshold value is set to a value that becomes greater the larger the negative pressure inside the brake booster.

A disaster recovery technology capable of achieving the high-speed FO and correctly reading the logs even if the unit of logs written in the main site is large is provided. In the disaster recovery system comprising a main site and a sub-site, when the writing in units of a log block consisting of a plurality of log records is performed in the main site and the logs are applied in the sub-site, the log blocks are read from the sub-storage to verify the consistency, and it is determined whether the reading process conflicts with the writing process through the remote copy operation when reading the logs. Then, only the log blocks in which the reading process does not conflict with the writing process as a result of the determination are applied to the database. Thereby, the logs are applied in the sub-site independently to recover the database.
