    摘要： Disclosed is an optical lens which can be produced by injection molding on an industrial scale and which has a high refractive index, a low Abbe's number, a low birefringence index, a high transparency and a high glass transition temperature. The optical lens can be produced by injection molding of a polycarbonate resin (preferably having a reduced viscosity of 0.2 dl/g or higher and a glass transition temperature of 120 to 160° C.), wherein the polycarbonate resin is produced by reacting a diol component comprising 99 to 51 mol % of 9,9-bis(4-(2-hydroxyethoxy)phenyl)fluorene and 1 to 49 mol % of bisphenol A with a carbonate diester. It becomes possible to produce an optical lens preferably having a refractive index of 1.60 to 1.65, an Abbe's number of 30 or smaller, a birefringence index of 300 nm or lower and an all light transmittance of 85.0% or higher.

    摘要： In one embodiment, an electric motor. A first bracket is fixed to the first side of a stator core in an axial direction, and is fixed to first bearing housing. A second bracket is fixed to the second side of the stator core, and is fixed to second bearing housing. The rotor includes a shaft rotatably supported by bearings, and an attached rotor core. Rotor core faces the inside of the stator core. A fan is attached to the shaft between the rotor core and the first housing. A flue formed between the first housing and the first bracket is configured to draw air from a port to a part of the first bracket. A rotation detection circuit includes a detected part fixed to the fan, and is within the flue. A sensor operable to detect the part is set in the flue, counter to the detected part.
