摘要： A color image forming apparatus has a color mode for color printing and a monochrome mode for printing at a higher speed than the printing speed of the color mode. The color image forming apparatus has mirrors 33, 35 and 37 that reflect the laser beams in order to guide the laser beams to optimum positions when the laser beams are guided from light sources (LD) to photoconductor drums 58, and in an optical system for the monochrome mode, the mirrors whose number is smaller than that in the other optical systems are arranged.

摘要： A trailing edge of a turbine rotor blade is formed so that a deflection angle of a blade surface in a downstream side of a maximum blade thickness portion is a predetermined value or less, by forming the trailing edge of the rotor blade so as to be inclined from a center line of a blade thickness toward an extension line of a suction surface. Since the trailing edge of the rotor blade is thus formed, a rapid increase of the deflection angle is prevented in a trailing edge portion of the rotor blade. Accordingly, a rapid ascent portion and a rapid deceleration portion are not generated in a suction surface velocity in a main stream unlike the conventional case.
