    • An information recording medium includes a first transparent electrode, and a carrier transport layer formed on the first transparent electrode for generating an electric current on the basis of fed carriers. A carrier generation layer formed on the carrier transport layer serves to generate carriers corresponding to a distribution of an intensity of incident information-writing light containing information, and serves to feed the generated carriers to the carrier transport layer. An electric power supply electrically connected to the first transparent electrode serves to generate an electric field corresponding to the distribution of the intensity of the incident information-writing light in cooperation with the carrier transport layer and the carrier generation layer. A photo-modulation layer formed on the carrier generation layer serves to record the information in the incident information-writing light in response to an application of the electric field generated by the electric power supply, and serves to modulate applied information-reading light in accordance with the recorded information. The photo-modulation layer is made of a complex member of high-molecule material and liquid crystal. A second transparent electrode is formed on the photo-modulation layer, and is electrically connected to the electric power supply. The carrier generation layer is made of inorganic material. The carrier generation layer may be made of organic material. In this case, a separating layer is provided between the photo-modulation layer and the carrier generation layer.

    • A combined radial and thrust bearing comprising: a radial rolling bearing including an outer ring provided with a large-diameter cylindrical portion the inner peripheral surface of which constitutes a raceway of rollers, a small-diameter cylindrical portion which extends from one end of the large-diameter cylindrical portion for carrying a thrust rolling bearing and which has a smaller diameter than the large-diameter cylindrical portion and a plurality of projections for preventing the thrust rolling bearing which is provided on the periphery at the end portion of the small-diameter cylindrical portion from coming off, and a plurality of rollers disposed on the inner peripheral surface of the outer ring and held by a retainer at regular circumferential intervals; and a thrust rolling bearing including axially arranged first race and second race, the first race being composed of an annular plate, a plurality of rollers disposed and held by an annular retainer at regular circumferential intervals and the second race being composed of an outer cylindrical portion and an annular plate portion, wherein the first race and the annular retainer of the thrust rolling bearing are placed over the small-diameter cylindrical portion of the radial rolling bearing, and each of the projections is engaged with the outer periphery of the opening of the retainer so as to prevent the thrust rolling bearing from coming off the radial rolling bearing. Assembly and processing of a combined radial and thrust bearing are facilitated and the performance thereof is increased.
