摘要： An optical sensor, an optical encoder, a torque detection apparatus, and an electric power steering apparatus less affected by fluctuations in the amount of detected light and with an improved resolution are provided. The optical sensor includes a first polarizing layer that splits incident light to light with a first polarization direction, a first photoreceiver that receives first polarized light split by the first polarizing layer, a second polarizing layer that splits the incident light to light with a second polarization direction, and a second photoreceiver that receives second polarized light split by the second polarizing layer. The first photoreceiver and the second photoreceiver are positioned alternatingly and spaced uniformly with each other.

摘要： A bearing apparatus has a rolling bearing including an outer ring (11), an inner ring (12), and rolling elements (13) disposed between the two rings, and a temperature sensor (TS) for measuring an internal temperature of the rolling bearing. A wire from the temperature sensor extends to the outside via a through-hole (11d) formed in a component of the bearing apparatus, and hence the temperature sensor can be disposed in a desired position with excellent wiring extension flexibility, thereby enabling a temperature in the desired position of the bearing to be measured. The temperature sensor, which can be configured thin in a small size with flexibility, can therefore be incorporated into whichever portion of the bearing, wherein a high response to temperature detection is attained, and detectability of abnormality in temperature can be improved.
