  • Publication number: 20090003742
    Abstract: An object of the invention is to provide a grease composition capable of keeping a good lubrication condition for a long period of time even when water has mixed therein, thereby inhibiting white structure flaking and corrosion. Another object is to provide a vehicular hub unit bearing which hardly suffers from white structure flaking and corrosion even when used in an environment where water may penetrate into it and which therefore has a long life. The invention provides a rolling bearing with, sealed up therein, a grease composition containing a waterproof film-forming additive added thereto; a grease composition for hub unit bearings, containing a base oil that comprises at least one of mineral oil and synthetic oil as the main ingredient thereof, and a thickener and a flaking inhibitor; and a vehicular hub unit bearing with the grease composition sealed up therein.

  • Patent number: 7471811
    Abstract: An image pickup apparatus is provided which performs correction of shading without performing correction of an image signal with a complicated algorithm or a large-scale correction circuit. The image pickup apparatus includes light irradiation unit that irradiates light on an object of image pickup and an image pickup element that receives reflected light or transmitted light from the object of image pickup to generate an electric signal corresponding to an amount of received light, in which a light receiving condition of a pixel of the image pickup element is changed such that shading of a signal from the image pickup element is corrected. The light receiving condition is changed by changing areas of opening portions of pixels 10-1 to 10-5 of the image pickup element, a shape of a lens provided on the opening parts, or an impurity concentration in a photoelectric conversion region of the image pickup element, or changing storage time, storing being performed through driving of the image pickup element.

  • Patent number: 6853748
    Abstract: Adaptive luminance interpolation processing in a signal processing apparatus for acquiring an image signal from an image sensing element having color filters and processing the image signal is described. An adaptive luminance interpolation circuit determines the correlation of the image signal in the vertical and horizontal directions, and interpolates the luminance signal of the image signal in a direction in which the correlation is higher. The chroma signal of the image signal is interpolated regardless of the correlation direction. The chroma signal is processed by a color conversion matrix circuit for performing signal processing of suppressing a false color in the vertical direction or a color conversion matrix circuit for performing signal processing of suppressing a false color in the horizontal direction, switched by a matrix switching circuit based on the interpolation direction.
