Abstract: A method of making a magneto-optical recording medium comprises the steps of moving a rotating substrate along a first dielectric target, at least one rare earth metal target, and a second dielectric target which are disposed in this order from an upstream side toward the downstream side in an in-line sputtering apparatus, and carrying out simultaneous sputtering on the substrate in the course of the movement of the substrate by use of the first dielectric target and the rare earth metal target. Thereafter, sputtering is carried out on the substrate by use of the rare earth metal target. Then, simultaneous sputtering is carried out on the substrate by use of the rare earth metal target and the second dielectric target.

Abstract: The invention provides an optical fibre having a synthetic resin cladding, comprising a glass fibre, a first cladding layer of a synthetic rubber and a subsequent cladding layer of a synthetic resin the molecules of which are oriented substantially in the longitudinal direction of the glass fibre, in which a low application temperature, a low pressure and a high cladding rate can be used in that the oriented synthetic resin is formed from a curable synthetic resin composition which comprises one or more oligomeric compounds the molecules of which comprise reactive groups and the molecular weight of which is smaller than 5000.The invention further relates to a method of manufacturing such an optical fibre and a device for cladding a glass fibre with a curable synthetic resin composition in which an elongation flow in the curable synthetic resin composition is produced to effect the orientation in the curable synthetic resin composition.

Abstract: A laser-induced CVD method in accordance with this invention comprises the steps of: setting a substrate in a reactive gas; applying a laser beam to the reactive gas to decompose it and produce not only free radicals but also ions due to multiphoton absorption; and applying an electric field thereby to efficiently transport the ions toward the substrate and deposit a thin film on the substrate at an increased deposition rate.

Abstract: A gas-phase growth process for growing films of uniform thickness or having a prescribed pattern form or growing films sequentially onto a substrate and an apparatus related thereto. The films are grown by allowing an inert gas to flow over a reaction gas flow in parallel to the surface of the substrate. Optionally, the substrate surface could be irradiated by a UV light source which is directed from above the inert gas toward the substrate surface.

Abstract: Glow polymerisate layers can be generated on a substrate, starting from hydrocarbons and/or fluorocarbons, by means of a high-frequency, low-pressure glow discharge. Glow polymerisates completely saturated with hydrogen or fluorine are obtained when the glow discharge is carried out in the microwave range between 0.5 and 1.000 GHz and if the amplitude E.sub.0 of the effective field strength in the vicinity of the substrate no greater than 850 V/cm.

Abstract: A process for forming a deposited film comprises introducing into a film forming space housing a substrate therein an active species (A) formed by decomposition of a compound containing carbon and a halogen and an active species (B) formed from a chemical substance for film formation which is reactive with said active species (A) separately from each other, irradiating them with light energy and thereby allowing both the species to react with each other thereby to form a deposited film on the substrate.

Abstract: A method for mending a damaged area in a papermachine fabric includes filling the defective area with a photosensitive resin, irradiating the defective area with ultraviolet light through a first mask having a multiplicity of light impervious dots in order to crosslink the irradiated regions and rinsing away the non-crosslinked regions of the photosensitive resin. The patch produced in this way is firmly bonded to the fabric of the papermachine fabric and also has a permeability sufficient for dehydration of the paper pulp.

Abstract: A ring is formed having alternating segments of ferromagnetic and paramagnetic materials. The ring is formed by first providing an annular ring of a high strength magnetic steel. Teeth are formed on the outer surface of the ring by forming troughs of the ferromagnetic material. Low pressure plasma deposition is used to fill in the troughs with a high strength paramagnetic material. The excess steel and excess plasma deposited material is removed to leave the finished ring of alternating segments of ferromagnetic and paramagnetic material.

Abstract: A process for forming a deposited film comprises introducing into a film forming space housing a substrate therein an active species (A) formed by decomposition of a compound containing germanium and a halogen and an active species (B) formed from a chemical substance for film formation which is reactive with said active species (A) separately from each other, then irradiating them with light energy and thereby allowing both the species to react with each other thereby to form a deposited film on the substrate.

Abstract: A process for the treatment of archival material such as books and other bound volumes. The treatment includes a radiation-induced polymerization of at least one vinyl monomer within the paper of the archival material. The process, which is carried out in a substantially nonaqueous system, may be used to improve the structure of paper as well as to provide some protection against degradation of the paper.

Abstract: A solid substrate, which contains or consists of a biologically or chemically active substance, is coated with coating material containing at least one polymerizable crosslinkable polyfunctional acrylic or methacrylic compound whereafter the coating material is subjected to polymerization substantially in the absence of non-polymerizable components to form a network coating of polymer on the surface of the solid substrate. This coating permits either the controlled release of active substance from the coated substrate or the controlled access of material reacting with said active substance into the coated substrate and the controlled release of the resulting reaction products from the coated substrate.

Abstract: A CDV method in which a substrate having a surface to be deposited where the film is placed in a reaction chamber and a reactive gas introduced into the reaction chamber is excited by irradiation with flat light and scattered light to thereby deposit the film on the substate surface. The flat light is directed along the substrate surface in close proximity thereto, and the scattered light is directed to the substrate surface thereto.

Abstract: The inside of a tube of an electrically insulating material is coated with a layer of electrically insulating material by reactive deposition of the coating material from a gas mixture which is passed through the tube. The tube is heated and the deposition is activated by a plasma produced by microwaves. The plasma reciprocates in the tube. Energy consumption is reduced by heating the tube to the reaction temperature at least partly by the energy supplied by the plasma to the tube wall. Thermal losses of the tube are reflected back to the tube wall by a heat reflecting element.

Abstract: A heat-sensitive material is incorporated into a fluid prepolymer precursor of a pressure-sensitive adhesive to form a stable mixture. The mixture is cast onto a substrate, and the prepolymer is polymerized into a pressure-sensitive adhesive by the action of ultraviolet radiation, electron-beam radiation, or a combination thereof.

Abstract: Small, preferably micronsized hollow glass or ceramic or carbon spheres (or a mix thereof) sprayed into a uncured or wet resin material which is formed into a layer and after curing of the resin layer, it is abraded, sand or grit blasted so as to rupture the outermost layer of spheres or voids to provide a plurality of anchor sites undercuts or nooks and crannies. A thermally sprayed metal, such as copper, becomes embedded into the undercuts, nooks and crannies, such that the bond or adherent strength is greatly improved. This micronsized glass, ceramic carbon spheres and/or pores greatly increases the bond strength by providing better undercuts in the surface to be sprayed by molten metal and provide the capability of depositing thicker layers without jeopardizing the bond.
