    摘要: To improve productivity and increase seizing resistance and abrasion resistance of a sliding surface of a tilt adjustment cylinder, a plurality of pistons are arranged cirumferentially in a cylinder block configured to rotate with a rotating shaft. Tip end portions of the pistons slide along the swash plate, and the pistons reciprocate. The swash plate is supported to tilt with respect to the rotating shaft. Further, a tilt adjustment driving portion is included. The tilt adjustment driving portion includes tilt adjustment large- and small-diameter cylinder chambers and tilt adjustment large- and small-diameter pistons configured to slide in the cylinder chambers to change the tilt angle of the swash plate. A sliding surface of the inner peripheral surface of each of the cylinder chambers includes a quenched portion formed by quenching using laser light, the sliding surface being a surface on which the tilt adjustment piston slides.

    摘要: An illumination optical system which illuminates an illumination objective surface with a light from a light source. The illumination optical system includes a spatial light modulator which includes a plurality of optical elements arranged within a predetermined plane and controlled individually, and which forms a light intensity distribution in an illumination pupil of the illumination optical system; and a polarization unit which is arranged in a position optically conjugate with the predetermined plane, and which polarizes an incident light beam having a first and second partial light beams, coming into the polarization unit such that the first and second partial light beams have polarization states different from each other, and emits the polarized incident light beam as an outgoing light beam, wherein the polarization unit changes, in a cross section of the outgoing light beam, a ratio between a cross sectional areas of the first and second partial light beams.
