There is provided a spindle motor including: a base member including an installation portion; and a stator core fixed to the installation portion, wherein the installation portion has a facing surface disposed so as to face a lower surface of a coreback of the stator core, and at least one of the facing surface and the lower surface of the coreback has a protrusion part formed thereon. The mounting angle calculation section calculates a mounting angle of the radar sensor from an azimuth of a speed zero observation point, the speed zero observation point being the observation point with a relative speed of zero. The coating may be conductive or resistive depending on the application. The mutually augmenting effects of the inner product execution units and SIMD-compatible composition enhances the level of operation parallelism dramatically. The primary antigen is a DNA molecule encoding an envelop glycoprotein of a primary isolate of HIV-1 while the boosting antigen is either a non-infectious, non-replicating HIV-like particle having the envelope glycoprotein of a primary isolate of HIV-1 or an attenuated viral vector expressing an envelope glycoprotein of a primary isolate of HIV-1.
