  • Patent number: 5620753
    Abstract: An optical fiber is releasably held in coil or skein form by a magnetized in film coating on the fiber. Adjacent convolutions are held together by a magnetic field to prevent unintended unravelling of the coil, but the fiber can be rapidly played out at high speed without rupture and with a constant release tension force. The magnetic field has a radial and axial component relative to the coil cylinder. A magnetizing apparatus is disclosed for magnetizing the film. A sensor feedback loop can dynamically adjust the reel-out drag force to dampen vibration modes during reel out which can cause tangle.

  • Patent number: 5167988
    Abstract: A ceramic coating bonded to an iron tubular member comprising a bonding layer formed on a surface of the iron tubular member by a reaction of an iron tubular oxide layer of the iron tubular member and a silicate; and an iron oxide diffusion-preventing layer produced from fine metal oxide particles or an organometallic binder by firing on a surface of the bonding layer. The ceramic coating may further comprises an oxidation-preventing layer, a heat-insulating layer, a refractory layer or a thin dense protective layer. It may be produced by coating the surface of the iron tubular member with a silicate binder to form a layer which is then converted to a bonding layer by a heat treatment in a steam atmosphere; coating the surface of the bonding layer with fine metal oxide particles or an organometallic binder to form an iron oxide diffusion-preventing layer; and after curing and drying firing the resulting ceramic coating in an atmosphere having an oxygen partial pressure of 10 mmHg or less.

  • Patent number: 4948674
    Abstract: To achieve a high adhesive strength of a metallization on an enamel, the surface of the enamel is first roughened and simultaneously treated by ultrasound to remove loose particles. Then the layer is conditioned by a wetting agent, activated and the metal layer is deposited chemically. Particularly good results are obtained when the conditioning and activation of the surface are performed at a temperature slightly elevated above room temperature, about 40.degree. C., for about 5 minutes and the roughening is performed chemically by treating with a 2% solution of ammonium hydrogen fluoride.

  • Patent number: 4937094
    Abstract: A method of forming a high flux of activated species, such as ions, of an energy transferring gas by employing a substantial pressure differential between a first conduit in which the energy transferring gas is introduced into a vacuumized enclosure and the background pressure which exits in said enclosure. In one embodiment, the flow rate of the energy transferring gas flowing through said first conduit, when taken in conjunction with said pressure differential, causes the high flux to activated species of the energy transferring gas to collide with a precursor deposition/etchant gas, remotely introduced into the enclosure through a second conduit, for forming deposition/etchant species therefrom. In an alternate embodiment, the pressure differential causes those activated species, themselves, to be either deposited upon or etched away from the surface of a remotely positioned substrate.

    Abstract: According to the present invention, there is provided an improved process for the formation of a deposited film by way of a microwave plasma CVD method, the improvement comprising monitoring an effective power of a microwave to be introduced into a reaction chamber, leading to a control means an output signal indicative of the effective power corresponding a plasma intensity, and automatically controlling the matching between the reaction chamber and the microwave to be introduced into the reaction chamber according to an output signal from the control means. According to the above process, even after a long discharge time has elapsed, the plasma intensity in the reaction chamber may be maintained constant, and the effective power of the microwave to be introduced into the reaction chamber may be therefore maintained constant.

  • Patent number: 4846101
    Abstract: An apparatus for generating a plasma in the lumen of a small diameter tube includes a housing having a diaphragm which separates the housing into a first chamber equipped with a gas inbleed assembly and a second chamber connected to a vacuum source. Parallel plate electrodes in the first chamber are encased in a dielectric which prevents substantially all plasma discharge external of a plasma zone between the electrodes. A conduit maintains gas flow between the chambers. A bore through the dielectric includes the plasma zone and receives the tube to be plasma treated.A method for treating the luminal wall of a plastic tube includes positioning a tube in the plasma zone, evacuating the chambers, bleeding a gas into the chambers, and delivering radiofrequency power to the electrodes. A long tube may be drawn through the plasma zone, or the dielectric and electrodes may be moved past the tube.
