Abstract: Particulate matter having precisely controlled length, width, thickness (i.e., height) and shape is produced with photolithographic techniques using a release film. In accordance with the method, a first photoresist layer is cured upon a substrate and a second photoresist layer is selectively cured upon the first photoresist to provide a desired pattern. The uncured portions of the second photoresist layer are removed so that a plurality of first and second deposition sites are produced wherein each said first and second deposition site has the desired area and wherein each first deposition site is located in a first plane and each second deposition site is located in a second plane. Further, portions of the substrate which are not part of the first deposition site are not located in the first plane and portions of the substrate which are not part of a second deposition site are not located in the second plane. The desired material is deposited using line-of-sight chemical deposition techniques.

Abstract: In a method of forming an ophthalmic lens from a synthetic material blank, in particular from a polycarbonate material, the blank is placed horizontally in a mold having optically finished molding surfaces. It is then subjected to a molding force at raised temperature in an oven. The mold has an upper molding surface that is part of a shell member adapted to slide freely in a ring. The molding force is limited to the static force due to the weight of the shell member, optionally increased by the weight of a pre-load mass surmounting the shell member.

Abstract: A method of fabricating an optical branching and coupling device includes the steps of preparing at least a pair of coated optical fibers; partly stripping the coating of the optical fibers; and fixedly inserting the coating stripped portions of the optical fibers into a pair of comb-shaped grooves under a condition prior to a unification step which is free from tension and torsional stress in an optical axial direction to bring the coating stripped portions into contact with each other between the comb-shaped grooves. The method also includes the steps of melting the coating stripped portions thus contacting each other by heating to unify the coating stripped portions and extending the coating stripped portions in the optical axial direction while in the melted state.

Abstract: A method of producing integral articles such as rudder parts etc. of plastics, reinforced with relatively long, continuous fibres is described. During the hot-setting or thermoforming process pressure is applied along at least two co-ordinate axes, with an angle between them of 30.degree. to 90.degree.. The method is characterized particularly in that to achieve the required pressures for each co-ordinate axis, from one of its co-ordinate directions a pressure element movable relative to the article is pressed against the article, while from the opposite co-ordinate axis at least one principally form stable reaction block or element in conjunction with said pressure element is caused to provide a pressure that acts on the article and against the direction of the force of the pressure element.

Abstract: A method is disclosed for the manufacture of an electrofusion coupler, for connecting adjoining lengths of thermoplastics pipes, and which coupler takes the form of a sleeve of thermoplastics material, to receive adjoining ends of adjoining pipes, the sleeve having an electrical resistance heater embedded therein and extended around the sleeve. In the method, a plastics preform is wound with a resistance heating wire, while heating the wire, to melt the surface of the preform, or applying molten plastics to the preform in the vicinity where the wire runs onto the preform, in order to ensure that the heating wire is fully embedded in the preform. A pressing roller may be run over the preform surface before the molten plastics has solidified, in order to smooth over the molten plastics. The preform 10 is subsequently placed in an injection mould and an outer encapsulating jacket is injection moulded around the preform.

Abstract: A plastic lens having a hard coat film and/or anti-reflecting film strongly adhered and having no defects such as yellowing, milky turbidities, cracks is provided. The plastic lens can be produced according to the present invention by forming an anti-reflecting film and/or a hard coat film on the working surfaces of a pair of molds, pouring a monomer liquid into the space between said molds and a ring gasket and polymerizing the monomer therein. Formation of the anti-reflecting film and/or the hard coat film can be carried out by coating of a hard coat solution or by a vacuum deposition of inorganic substances. When the anti-reflecting film and/or the hard coat film is formed by coating of a hard coat solution, a hard coat solution containing at least one release agent is applied to the working surfaces of the molds, or, after applying a release agent to the working surfaces of the molds, a hard coat solution containing no release agent is applied to the release agent layer.

Abstract: A multilayered molding is disclosed, which has a base molding outer layer mainly composed of a partial crosslinking type substance A obtained from polyolefin resin and ethylene-.alpha.-olefin copolymer rubber or a mixture B of polyolefin resin and ethylene-.alpha.-olefin copolymer rubber or both. The outermost layer is in direct contact with and forms a lamination with an inner intermediate layer or a base molding composed of a polyethylene resin, for instance, and is firmly bonded to the outermost layer. A method of manufacturing such multilayered molding is also disclosed, in which a composite sheet of the thermoplastic elastomer with or without the intermediate layer is preliminarily heated, followed by being suction held in close contact with a mold cavity inner surface, thus forming a surface layer. The mold is then clamped, and fluidized and plasticized polyolein resin is injected to produce the molding. The polyolefin resin may also be injected prior to the clamping.

Abstract: A method for fabricating in a mold a rotatable recording drum. Initially, the mold is rotated and a predetermined quantity of a flowable substance is poured into the mold cavity and is centrifugally flung against the mold wall to form a mold layer with a smooth inner surface. Next, a surface substance is poured into the mold cavity and is allowed to harden against the mold layer. A core outer layer substance is then poured into the mold cavity and allowed to harden against the surface substance, and rotation of the mold is stopped. The mold layer fluid is removed, and the cavity inside the outer layer is filled with a core inner layer substance which is allowed to harden before the drum core is removed from the mold cavity. Following removal of the core from the mold cavity, the hardened surface substance may be vacuum coated, and a protective overcoat applied to the core. The drum core and the surface substance can also be formed separately.
