An information processing apparatus inputs image data and calculates a relative magnitude between coefficient or pixel values of the input image data. As is already known, the surfaces of the bearing sleeve and the shaft facing each other form at least one radial bearing region and the surfaces of the bearing sleeve, the cover plate and the thrust plate facing each other form at least one axial bearing region. The user interface rotates or unfolds from the holster so that the user can interact with the user interface. The silicon single crystal has a nitrogen concentration of >5\xd71014 atomscm3 and \u22666\xd71015atomscm3, a carbon concentration of \u22671\xd71015 atomscm3 and \u22669\xd71015 atomscm3, and heat treatment is performed in a noble gas atmosphere having an impurity concentration of \u22665 ppma, or in a non-oxidizing atmosphere.
