  • Patent number: 10307964
    Abstract: A three-dimensional molding method in which a step of sintering a powder layer with a laser light or an electron beam after a flat surface has been formed by sliding of a squeegee against the powder layer is repeated in a prescribed number of times, and then the periphery is cut, in order to mold both the object 1 to be molded and a support structure 2 that supports the lower side of the object 1 from below and is intended to be removed after molding, wherein in the support structure 2, the upper parts of the struts connected to the object 1 to be molded employ truncated circular conic shapes or partial truncated circular conic shapes that are reduced in diameter toward the top.

  • Patent number: 9003619
    Abstract: The present invention has an object to provide a fiber-spreading method which can form a thin spread fiber sheet having a large and uniform spread width by uniformly distributing fibers of a fiber bundle having an increased number of fibers. Since a set of regions Si each including a pair of a fiber-spreading region Ai and an expansion region Bi are arranged in a movable region M set so that the fibers of the fiber bundle can move in the width direction, the fiber-spreading region Ai moving the fibers in the width direction while bending the fibers by letting a fluid pass through the fiber bundle, thereby spreading the fiber bundle to a spread width Wi (i=1, . . .

  • Patent number: 8276637
    Abstract: An end of a sheet drawn out form a feeder is clamped by a pair of upper and lower clamping devices of two or more pairs. The sheet is drawn out from the initial position to the end position in a spread state. While the spread sheet is being tentered on pin tenters, another pair of upper and lower clamping devices at the end position is separated from each other and moved along the respective rails into the initial position. The end of the sheet drawn out from the feeder is clamped from above and below at the initial position with the upper and lower clamping devices that has returned to the initial position.

  • Patent number: 7967182
    Abstract: Provided is a dissimilar metal joint product of nickel-titanium alloy material and pure titanium material, having a tensile strength at the joint not less than that of the pure titanium material before joining, having a small variation in the strength at the joint, and having narrow heat-affected zone after joining, and a method for joining thereof. A round rod 1 of the nickel-titanium alloy material is integrally joined with a round rod 2 of the pure titanium material, while rotating at least one of the joining faces for conducting frictional pressure welding, applying a specified upset force thereto to compress thereof, after the start of deceleration of the rotation, in a period where peripheral velocity in the outermost periphery of the rotation in the joining face is not less than 0.5 m/sec. A reaction layer structure is formed at the joint by the compressive force induced by the upset force and by the rotational force of decelerating rotation.

  • Publication number: 20060137156
    Abstract: A method of producing a spread multi-filament bundle and an apparatus is used in which an arbitrary number of multi-filament bundles of higher strength are simultaneously spread with high speed and a high-quality. A spread multi-filament bundle or sheet with the component monofilaments thereof aligned in parallel widthwise and uniformly distributed in density is produced. The respective multi-filament bundles fed from a yarn supplier or a creel are subjected to fluctuation of the tensile force applied thereto alternatively between tension and relaxation and the respective bundles as subjected to such fluctuation are passed in succession through a fluid flowing spreader.
