    摘要： Revolution speeds nca, nib of rolling elements 9a, 9b are sensed by a pair of revolution speed sensors 21a, 21b. Also, a rotational speed ni of a hub 2 is sensed by a rotational speed sensor 15b. A sum “nca+ncb” or a difference “nca−nib” the revolution speeds of rolling elements 9a, 9b in double rows is calculated based on sensed signals of the revolution speed sensors 21a, 21b, and then a ratio “nca+nib/ni” or “nca−ncb/ni” of this sum or difference to the rotational speed ni is calculated. Then, the radial load or the an axial load is calculated based on the ratio “nca+ncb/ni” or “ca−nib/ni”.

    摘要： The invention provides a polarization-converting unit capable of being sufficiently cooled even when polarization-converting elements and a lens array are unitized together. Polarization-converting elements and a second lens array are held by a holding frame and a flow-inlet-side opening is arranged under the holding frame, and a flow-outlet-side opening is arranged over the holding frame so as to form a polarization-converting unit. Therefore, cooling air can be allowed to vertically flow through a clearance between the polarization-converting elements and the second lens array, thereby sufficiently cooling the polarization-converting elements and the second lens array from the faces thereof opposing each other. Therefore, in particular, the thermal effect to phase-difference plates pasted to the opposing faces of the polarization-converting elements can be reduced, and thereby the phase-difference plates are prevented from being peeled off so as to maintain the sufficient image quality.
