  • Patent number: 7013716
    Abstract: A surface capacity parameter is determined for a surface of an article having irregularities therein that can be characterized by peaks and valleys relative to a reference point. Initially, an area of interest on the surface of the article and a lateral resolution of that area of interest are determined. An apparatus generates a visual representation of the area of interest on the surface of the article. A deflection contact part factor for the article is calculated, and a bearing ratio curve level is determined based upon the calculated deflection contact part factor and the magnitude of the height or distance between the tallest peak and the lowest valley on the surface of the article. The volume of the material comprising the peaks in the surface of the article and the volume of the space in the surface of the article that is available for the retention of a fluid, such as a lubricant, are determined.

  • Patent number: 6865927
    Abstract: A micro-object having a desired sharp point or edge may be optically tested during fabrication. This is accomplished by applying a known force to the workpiece against an optically opaque layer disposed on a transparent substrate, passing light down the workpiece toward the opaque layer, and determining whether the shaped portion of the workpiece has sufficiently penetrated the opaque layer so that light passed through the workpiece can be detected on the remote side of the transparent substrate. If the light is not detected, the shaped portion of the workpiece is considered to be insufficiently sharp, and the workpiece can be subjected to further shaping operations. In another arrangement, after the force is applied to cause penetration of the opaque layer by the shaped portion of the workpiece, the substrate and the workpiece are moved laterally with respect to one another so as to form a scratch on the opaque layer.

  • Patent number: 6568252
    Abstract: Disclosed is a method for testing the smoothness of a disc surface. A glide test is performed by first lowering the glide head until contact between the glide head and the disc surface occurs. The point of contact establishes a base line indicating the location of the disc surface. Once a base line is established, the glide head can be controlled so that it flies at the desired glide height above the disc surface. By first establishing the base line, the glide head can be flown with greatly increased precision at the desired glide height based on known relationships between glide height and various parameters, including spindle speed, various electrical parameters, or crown shape.
