According to one embodiment, a stereoscopic video processor includes a mode setting module, an adjustment module, and a communication module. The mode setting module sets a mode from among a plurality of modes each specifying an adjustment amount related to the disparity between first stereoscopic video and second stereoscopic video. The adjustment module adjusts the disparity between the first stereoscopic video and the second stereoscopic video by an adjustment amount corresponding to the mode set by the mode setting module. The communication module communicates with stereoscopic glasses for viewing the first stereoscopic video and the second stereoscopic video the disparity between which is adjusted by the adjustment module.

A spot size converter comprising an incident area of a first size, an exit area of a second size different from the first size, and side walls defining a light guide, wherein at least a part of side wall inclines from the width direction axis and the thickness direction axis of the incident area is provided. Thereby, it is able to regulate the divergence of the outgoing light, and to optically couple optical elements of different spot size with each other at a high-efficiency. Moreover, the semiconductor laser module and optical fiber laser device using such a spot size converter are provided.

Light from a first excitation light source is incident on one facet of a first optical fiber. A core is doped with a first rare earth substance. A resonant section induces light resonance in the core to generate resonant light, thereby providing selected light at the other facet of the first optical fiber. An optical multi/demultiplexer reflects the light of the selected wavelength in a direction different from that of the first optical fiber. A second excitation light source supplies light to the resonant section of the first optical fiber via the optical multi/demultiplexer and the other facet of the first optical fiber. A second optical fiber guides the light of the selected wavelength from the optical multi/demultiplexer to an exterior.

A superfinishing method of a tapered roller bearing, including the steps of: rotating an outer ring of the tapered roller bearing about a center axis thereof; inserting a straight-shaped superfinishing stone from a front face of outer ring; and slidingly contacting a leading end face of the superfinishing stone with a taper-shaped raceway surface formed in an inner peripheral surface of the outer ring to thereby superfinish the raceway surface. The superfinishing stone is inclined outwardly of the front face of outer ring with respect to a vertical line of the raceway surface.
