The present invention is directed to tripyridyl carboxamide compounds which are antagonists of orexin receptors, and which are useful in the treatment or prevention of neurological and psychiatric disorders and diseases in which orexin receptors are involved. An automatic business-to-business template generator is provided for supporting workflow design. A superimposed-image processing unit then superimposes the distribution of the variance of the velocity components according to the velocity-variance image on an average absolute-value image, and an image display unit displays a superimposed image. The cylindrical portion of the first yoke and the outermost-diameter portion of the rotating yoke face each other across a gap in the radial direction, and the cylindrical portion of the second yoke and the flat surface portion of the rotating yoke face each other across a gap in the shaft direction. The coupling component is configured to couple with a handheld computer.
