Tire vulcanizing method
Provided is a tire vulcanizing method enabling an optimum vulcanization operation for each tire by measuring the temperatures of the inner surface and the outer surface of a tire until the demolding timing without damaging the tire and by determining the vulcanized state of the tire accurately based on the measured temperature data to efficiently produce uniformly vulcanized tires especially under conditions where the temperature of a mold fluctuates. During vulcanization of a tire G, the temperatures of the inner surface and the outer surface at a plurality of principal portions representing the tire G are measured, and the demolding timing is determined according to the equivalent degree of vulcanization indicating the degree of progress in crosslinking reaction calculated based on the temperature data measured.
RUBBER TEMPERATURE MEASURING DEVICE AND RUBBER PRODUCT MANUFACTURING METHOD
In a rubber temperature measuring device, a temperature sensor and a biasing member are disposed in an installation hole formed in a molding surface of a mold. The temperature sensor is biased by the biasing member and a temperature detecting unit at a tip end projects from the molding surface and is not in contact with the mold. The mold is closed and vulcanized in a state in which a green tire making contact with the temperature detecting unit presses the temperature sensor against biasing force of the biasing member and an opening portion of the installation hole is blocked by the temperature detecting unit. Temperature data detected by the temperature detecting unit is input to a control unit disposed outside the mold through a communication line extending in a communicating hole communicating with the installation hole.
IMPRINT APPARATUS, IMPRINT METHOD, AND ARTICLE MANUFACTURING METHOD
The present invention provides an imprint apparatus including an irradiation unit configured to irradiate a peripheral region of a pattern region of a mold with light while the mold is in contact with an imprint material on a substrate so as to make a polymerization degree of the imprint material between the peripheral region and the substrate fall within a range higher than a polymerization degree in an initial state when the imprint material is supplied onto the substrate and lower than a polymerization degree in a final state when the imprint material is cured, and a control unit configured to control, for each shot region on the substrate, a value of a second parameter for controlling irradiation with the light from the irradiation unit based on a value of a first parameter for controlling a contact step.
Steerable heat source
An apparatus includes a pressure vessel and a steerable heat source disposed within the pressure vessel. The apparatus also includes one or more control systems coupled to the steerable heat source. The one or more control systems are configured to direct supplemental heat toward a targeted region within the pressure vessel using the steerable heat source.
Composite automated debulk machine for large scale parts
An assembly for debulking an uncured stack of plies of fiber reinforced composite material positioned on a forming tool, including a force application element and a heat source, associated with the force application element. The heat source is positioned in at least one of the following positions: spaced apart from a top ply to directionally heat the uncured stack of plies from the top ply through a bottom ply of the uncured stack of plies; with the forming tool positioned between the heat source and the uncured stack of plies, the heat source to heat the forming tool, to directionally heat the uncured stack of plies in a direction from the bottom ply through the top ply; or between the uncured stack of plies and the forming tool, to directionally heat the uncured stack of plies in the direction from the bottom ply through the top ply.
THERMAL BEHAVIOR PREDICTION FROM A CONTONE MAP
Examples of a thermal behavior prediction method are described herein. In some examples of the thermal behavior prediction method, a predicted heat map of a layer corresponding to a three-dimensional (3D) model is computed using at least one neural network. The predicted heat map is computed based on a contone map corresponding to the 3D model.
METHODS AND APPARATUSES FOR CASTING POLYMER PRODUCTS
In an example method of forming a waveguide film, a photocurable material is dispensed into a space between a first mold portion and a second mold portion opposite the first mold portion. Further, a relative separation between a surface of the first mold portion with respect to a surface of the second mold portion opposing the surface of the first mold portion is adjusted. The photocurable material in the space is irradiated with radiation suitable for photocuring the photocurable material to form a cured waveguide film. Concurrent to irradiating the photocurable material, the relative separation between the surface of the first mold portion and the surface of the second mold portion is varied and/or an intensity of the radiation irradiating the photocurable material is varied.
Systems and methods for gamma radiation based stabilization of replicated mirror structures at the nanometer-scale
A system includes a curing assembly for low temperature curing and residual stress relief of material substrates. The curing assembly includes a first exposure chamber configured to expose the material substrate to UV radiation, and a second exposure chamber configured to expose the material substrate to Gamma radiation. In some embodiments, a mixing apparatus may mix nano-filler particles into the material substrate prior to exposure to Gamma radiation. The cure assembly may also include a control system for determining exposure dosages and exposure times based at least in part, on the material properties of the material substrate.
Systems, cure tools, and methods for thermally curing a composite part
An example method for curing a composite part includes placing the composite part onto a topside of a cure tool, and a bottom surface of the composite part contacts the topside of the cure tool and a top surface of the composite part is opposite the bottom surface of the composite part. The method also includes placing the cure tool and the composite part into an autoclave, using the autoclave to apply external heat to the cure tool and the composite part so that air flows over the top surface of the composite part to heat the top surface, and applying additional heat to a backside of the cure tool via radiation provided by at least one heating source of the cure tool, so as to reduce a temperature difference between the backside of the cure tool and the top surface of the composite part being cured.
Device and method of manufacturing a structure made of a curable material by means of molding
A device for varyingly irradiating by means of ray shaping is described. Furthermore, a method of manufacturing a structure made of a curable material by means of molding is described. In a first step of the method, a molding tool is arranged above a surface such that the curable material abuts on the surface and a molding surface, facing the surface, of the molding tool in a region between the molding tool and the surface and such that further curable material may continue to flow to the region. In a second step, the curable material is irradiated in the region in a locally varying manner such that the ray experiences ray shaping in an optical channel and such that the curable material cures at different speeds in a laterally varying manner.
