  • Patent number: 7104533
    Abstract: A cylindrical vibration-damping device includes: a rubber bushing having a rubber elastic body elastically connecting an inner sleeve and a resin outer sleeve; a rigid mounting member having a cylindrical bore into which the rubber bushing is press fit; an engaging stepped face formed on an inner surface of the mounting member; and an engaged stepped face produced on an outer surface of the outer sleeve once the outer sleeve is press fit into the cylindrical bore of the mounting member, by means of elastic deformation of the outer sleeve. The engaged stepped face is opposed to the engaging stepped face in an axial direction of the device, and is brought into engagement with the engaging stepped face so as to exhibit a resistance to dislodging of the rubber bushing from the mounting member in at least one of opposite axial directions. The method of producing the same is also disclosed.

  • Patent number: 6396948
    Abstract: A technique for compressing video images uses temporary compression of blocks during compression, integrated color rotation of compressed images, direct compression of a composite video signal, and border filters to allow blocks to be compressed independently. Temporary compression reduces storage needed in an integrated circuit. An incoming frame is compressed block-by-block and placed in temporary storage. A corresponding block of a later frame is also compressed. Both blocks are decoded back into the transform domain and the two blocks are compared in the transform domain. Color rotation on compressed color information is integrated with overall compression and is performed upon the chrominance transform pyramids after transformation of the video signal rather than performing a rotation on the raw signal itself. Color rotation is performed at any stage and uses serial multiplication (shift and add) for more efficient processing, rather than using parallel multiplication.
