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.

An actuation mechanism for an electromagnetic switch for a hydraulic cylinder includes a housing adapted to be inserted into a cylinder head. A rod is slidably engaged in the housing and is adapted to move between a first position and a second position. A biasing element, which may be located inside or outside of the housing biases the rod into the first position.

A safety device for maintaining a load raised cylinder linkage in selected extended position. A combination cylinder engagement rod and locking sleeve with a piston rod engagement channel that will adjustably secure and extended piston rod from a cylinder assembly in a safe secure locked extended position. The cylinder safety stop of the invention is interposed between the cylinder sleeve and the piston end block by the incrementally adjustable engagement panel's positioning via removably positioned stop adjustment pin. An intermediate incrementally adjustable fitting provides for positioning between multiple aligned stop pin engagement apertures.
