    Abstract: There is provided an air foil bearing. The air foil bearing comprises a bearing house and a first foil, wherein a first end of the first foil is fixed with respect to the bearing housing and a second end of the first foil is extended along a peripheral surface of a rotating shaft while maintaining a predetermined clearance with respect to the rotating shaft to thereby become a free end. The air foil bearing also comprises a second foil fabricated from a porous metallic material and extended along the first foil between the first foil and the bearing housing.

    Abstract: An image forming apparatus includes a photoconductor, a laser scanning unit to scan a beam across the photoconductor to form an electrostatic latent image on the photoconductor, a developing unit to apply a developer to the photoconductor having the electrostatic latent image formed thereon to form a visible image on the photoconductor, and a transferring unit to transfer the visible image, formed on the photoconductor, to a print medium. The laser scanning unit includes a light source to generate a beam according to an image signal, a polygon mirror including a plurality of reflection surfaces to deflect the beam, generated by the light source, in the main scanning direction, the reflection surfaces being aspherical to correct an aberration of the beam to converge the beam, deflected in the main scanning direction, on the photoconductor, and a motor to rotate the polygon mirror.

    Abstract: Embodiments of the present invention may provide a coating material having heat resistance, abrasion resistance and low friction characteristics, which is coated on an operating component such as a rotating shaft working at a high speed without oil supply in a medium temperature environment (400° C.˜500° C.). This is so that the operating body can sufficiently withstand friction, heat generation and abrasion caused by contact with a bearing. The coating material of the present invention comprises 15 to 25 wt % antimony trioxide (Sb2O3), 50 to 70 wt % binder, 10 to 20 wt % tungsten disulphide (WS2) and 5 to 15 wt % silver (Ag). The binder comprises 60 to 80 wt % nickel (Ni) and 20 to 40 wt % chromium (Cr).
