  • Patent number: 5888638
    Abstract: A sealing element is made up of a shut-off body with a sealing surface; a bonding layer component provided on the sealing surface of the shut-off body and containing silicon and carbon; and a sliding layer component provided on the bonding layer component and containing silicon and carbon. The bonding layer component has a silicon content greater than that of the sliding layer component so that the bonding layer component has more ductile properties than the sliding layer component. The sliding layer component is harder than the bonding layer component. The sliding layer component is thinner than the bonding layer component and less than one um so that the bonding layer component takes up stresses of the sliding layer component without impairing adhesion capability of the bonding layer component to the sealing surface.

  • Patent number: 5851666
    Abstract: A process for producing a preform for elastic optical fiber having a refractive index distribution in which the refractive index is gradually decreased from the center of the preform toward the outer periphery thereof, by depositing a deposition layer comprising a polymer A (refractive index: N.sub.a) and a refractive index modifier having a refractive index different from that of the polymer A onto an inner surface of a hollow cylindrical member rotating about an axis thereof, by use of vapor-phase deposition based on a CVD (Chemical Vapor Deposition) process, or a coating process. A plastic optical fiber preform comprising deposition layers having a gradually increasing refractive index distribution is formed by changing the mixing ratio between the polymer A and the refractive index modifier constituting the deposition layer.

  • Patent number: 5807634
    Abstract: A method for improving the adhesion of alkylated chlorosulfonated polyethylene (ACSM) and chlorosulfonated polyethylene (CSM) rubber compounds to a resorcinol-formaldehyde latex (RFL) treated polyester reinforcing element using lower than conventional heat set temperatures comprising dipping the element into a RFL dip comprising chlorosulfonated polyethylene; drying the element; heat setting the element at a temperature in the range from about 300.degree. F. to about 425.degree. F. under tension; incorporating the element into the rubber compounds; and curing the element and the rubber compounds. Further, adding an amine functional polyacrylate to the RFL dip prevents failure of the adhesion of the cord at start up temperatures of about -40.degree. F.

  • Patent number: 5677372
    Abstract: An improved adhesion or bonding between diamond fibers and a matrix of at least one organic polymer such as a resin is achieved in a composite material reinforced with vapor-deposited diamond. To improve bonding to the matrix, hydrogen is removed from the surface of vapor-deposited diamond fiber. This can be achieved by heating the diamond under an oxidative atmosphere at a temperature of about 150.degree. C. to about 800.degree. C., or under a non-oxidative atmosphere at a temperature of about 800.degree. C. to about 1500.degree. C. The surface of the vapor-deposited diamond, which contains not more than about 1.times.10.sup.15 /cm.sup.2 of hydrogen atoms, is bonded to the matrix of resin for example with sufficient strength. To further improve bonding, diamond doped with B or N is employed as the reinforcing material or at least a surface layer thereof.
