  • Patent number: 6143027
    Abstract: An intraocular lens is described that includes an optic portion formed of an optically suitable polymer or glass material that has been coated by a fluorocarbon polymer. A haptic portion of the IOL is attached to the optic. The resulting low-energy IOL surface induces significantly reduced cell damage when contacted with corneal endothelial tissues. The fluorocarbon polymer coating is preferably applied by exposing IOL surfaces to a plasma formed from a gaseous fluorocarbon monomer. The resulting IOL causes substantially less damage to corneal endothelial cells during implantation.

  • Patent number: 6125628
    Abstract: In a water-cooled engine comprising a catalyst for purifying exhaust in an exhaust pipe, a catalyst is rendered active at an early stage by arranging an air-fuel ratio of a fuel mixture supplied to the engine to be lean on startup. A catalyst activation water temperature corresponding to full activation of this catalyst is set, and the air-fuel ratio is arranged to be leaner than a theoretical air-fuel ratio during a period from engine startup to when a cooling water temperature reaches the catalyst activation water temperature. After the cooling water temperature reaches the catalyst activation water temperature, the air-fuel ratio is shifted to the stoichiometric air-fuel ratio. In this way, lean control is optimized to activate the catalyst.

  • Patent number: 5881038
    Abstract: A recording and reproducing system for performing the reproduction using an optical recording medium. A physical feature of a ROM type disk is extracted and enciphered before being recorded in an optical disk. The cipher reproduced and converted into a plain text physical feature, which in turn, is compared with the physical feature information detected from the ROM disk. When both are coincident with each other, the operation of the system stops, thereby preventing the use of an illegally duplicated disk. The physical feature information, recorded on a magnetic recording layer 4 of the optical recording medium 2, is reproduced by an optical head 8 and compared with the information measured by a physical feature information detector, thereby detecting a duplicated medium.
