A process for fabricating a partially polymerized prepreg material. Fibers are impregnated with thermosetting resin. The resin is partially polymerized to a degree of polymerization between 10% and 60%. The thermosetting composite parts are produced by drape forming of the prepreg material. The material laid-up in the form of tapes and heated at a temperature above the glass transition temperature of the prepreg state. The laid-up material is pressed and cooled to return the laid-up material to a temperature below the glass transition temperature of the prepreg state in question.

Methods are disclosed including thermally processing a scaffold to increase the radial strength of the scaffold when the scaffold is deployed from a crimped state to a deployed state such as a nominal deployment diameter. The thermal processing may further maintain or increase the expansion capability of the scaffold when expanded beyond the nominal diameter.

A female loop portion for a hook and loop self-adhesive, comprising a film (1) made of at least one thermoplastic and a plurality of filaments (2) which are separate from one another and attached to one of the surfaces of the film, each filament comprising a series of fastening sections (15) and a series of loop sections (4) alternating with the fastening sections, the filaments being attached to the film along the fastening sections while the loop sections are at a distance from the film so as to form loops, and characterized in that a cross-sectional area of one loop section of a filament is less than a cross-sectional area of one fastening section of said one filament.

A heat-shrinkable tube heating apparatus of the present invention comprises a pair of heat source boxes that are configured to be plane-symmetrical to each other. A blower pipe and a pair of heating tubes are disposed parallel to each other inside each of the pair of heat source boxes wherein air jet holes are formed side by side on the blower pipe. The pair of heating tubes, each including a heating wire emitting infrared rays, are arranged across an open area on one side of each heat source box, the blower pipe is disposed between the pair of heating tubes to be positioned more inside than the pair of heating tubes from the open area, and the blower pipe is installed so that a pressurized air flowing thereinto is blown out through the air jet holes toward one of both sides of heat-shrinkable tubes placed for being heated.

A method of calibrating a three-dimensional measurement system having a plurality of cameras and at least one projector is provided. The method includes performing a full calibration for each camera/projector pair where the full calibration generates at least two sets of correction matrices. Subsequently, an updated calibration is performed for each camera/projector pair. The updated calibration changes less than all of the sets of correction matrices.

A method and apparatus for sealing a bag made of a polymeric material by applying heat activated layers on different portions of the bag, wherein the first adhesive layer and the second adhesive layer have respective heat activation temperatures below the softening point temperature of the polymeric material; after creasing the bag along a fold line, applying heat at a temperature below the softening point temperature of the polymeric material to activate the first adhesive layer and the second adhesive layer to adhesive states after the bag has been filled with contents; and folding the bag to form an adhesive-to adhesive seal by contact between the heat activated first adhesive layer and the heat activated second adhesive layer.

A method for making low shrink polyester films wherein the films are arranged in stacks, tentered, heat treated, and relaxed in unison. Also, polyester films produced by such method.

A three-dimensional shaping device includes: a plasticizing unit configured to plasticize a material to generate a plasticized material; a stage having a deposition surface on which the plasticized material is deposited; an ejection unit that has a plurality of nozzles arranged side by side along a first axis parallel to the deposition surface of the stage, and that is configured to eject the plasticized material in a continuous linear form from the plurality of nozzles toward the deposition surface; an ejection switching unit configured to individually switch between stopping and resuming ejection of the plasticized material from the plurality of nozzles; a moving unit configured to move the ejection unit with respect to the stage along a second axis that is parallel to the deposition surface of the stage and that intersects the first axis; and a control unit configured to laminate a shaping layer formed of the plasticized material on the deposited surface of the stage by controlling the plasticizing unit, the ejection switching unit, and the moving unit.

A method for producing a fencing material including the steps of: providing a border material having an interior surface; providing a mesh material having a front and a back; treating the interior surface of the border material to produce a tacky border material surface; placing a portion of the front and/or the back of the mesh material against the tacky border material surface; pressing the tacky border material surface and the mesh material together; and thermally bonding at least some portion of the front and the back of the mesh material with the interior surface of the border material. The border material being a polyvinyl chloride, the mesh being a polyvinyl chloride material and/or a vinyl coated material.

An air flow controller includes: a box-shaped body cover that is disposed above and/or below a film running surface to be adjacent to an upstream side of an entrance of a tenter oven in a film running direction and/or a downstream side of an exit of the tenter oven in the film running direction, the box-shaped body cover extending in the film running direction and having a surface facing the film running surface and being open. The box-shaped body cover includes at least one partition structural body in the box-shaped body cover, the partition structural body extending in a width direction of the film and separating inside of the box-shaped body cover into a plurality of chambers, and each of at least two of the chambers is provided with an air discharge mechanism configured to discharge air in a corresponding chamber.
