Abstract: A prior simulation of a velocity field and a temperature field is carried out, and snapshot data of the velocity field and that of the temperature field are collected during the prior simulation. Then principal component analysis on the collected snapshot data obtains velocity-field and temperature field dimension transformation matrixes, on the based on which the analysis models of the velocity field and temperature field having respective first degrees of freedom are converted into reduced degree-of-freedom models. Consequently, a simulation of the velocity field and the temperature field is carried out using models having respective reduced degrees of freedom (i.e., second degrees of freedom).

Abstract: An apparatus and method for supporting harness design. Harness information including a pass position of a harness is set on a three-dimensional model. Then, it is determined whether the harness whose position is decided so as to pass through the set pass position interferes with a mechanical part that is read from a storing unit that stores therein three-dimensional model data on the mechanical part through which the harness passes. When it is determined that the harness interferes with the mechanical part, from among a plurality of surfaces of the mechanical part, a surface that has not been selected is selected, and a pass position of the harness is set outside the selected surface. Then, a position of the harness that passes through the set pass position is decided. These processes are repeated until it is determined that the harness does not interfere with the mechanical part.

Abstract: A technique that increases operability in changing the rotational speed of a spindle in a power tool. The rotational speed can be changed in three levels by utilizing a planetary gear mechanism. The third gear position is located in an intermediate position in the sliding direction of the speed changing part. The first speed change position is located on one side of the third speed change position. The second speed change position is located on the other side of the third speed change position. During operation, shifting between the first and third speeds can be done without going through the second speed each time. Further, shifting between the second and third speeds can be done without going through the first speed. Therefore, speed change shifting can be facilitated.
