摘要： An important component selection device is provided for selecting a component having a higher importance in a simulation calculation, so that the component having a higher priority is calculated firstly by a calculation device and the importance of the updated component is re-evaluated so as to be reflected in the calculation thereafter. When a high speed is required, the ranking of the important components are realized by hardware. Moreover, when a storage device has a plurality of candidate value data for each of the component data and the calculation device updates the candidate values one by one, the magnitude of variety of the candidate values is used as the importance of the component data and the component having this value which is large is calculated with a higher priority so that the calculation of the component having a small change is omitted, thereby increasing the simulation speed.

摘要： A controller of a cell phone serving as the position detector reads time-sequentially anteroposterior positional information Pi−1, Pi+1, together with interest positional information Pi that is an object of determination (S103), and calculates, for example, vectors V1 and V2 showing a shift from Pi−1, to Pi and a shift from Pi to Pi+1, respectively (S104, S105), in order to calculate an amplitude of fluctuation representing a direction of change. The amplitude of fluctuation representing a direction of change is expressed by a value of dot product of the calculated vectors V1 and V2 (S106). When the value of dot product is lower than a predetermined value (S107: YES), a position is shown to greatly deviate in the vicinity of the interest positional information Pi. Therefore, the amplitude of fluctuation representing a direction of change is judged to be large, and the positional information is determined to be error (S108).

摘要： Even if an internal combustion engine is stopped having a lock pin of a vane rotor kept disengaged from a lock recess, subsequent engine starting can instantly move the vane rotor to a desired angular position where the lock member an be engaged with the lock recess. The vane rotor has therein two passage control mechanisms each having a hydraulically actuated valve body. When the valve body is moved to a given position, retarding and advancing hydraulic holes become communicated to each other through an annular groove of the valve body. Due to this ON communication, retarding and advancing operation chambers become communicated, so that reciprocative swing movement of the vane rotor induced by an alternating torque produced at the starting of the engine is effectively made and thus the vane rotor can be quickly turned to the desired angular position for ease of engine starting.
