  • Patent number: 11448578
    Abstract: This invention relates to a method of evaluating powder for lamination shaping by stable criteria. In this method, it is evaluated whether powder for lamination shaping can be spread into a uniform powder layer in the lamination shaping, wherein the powder is evaluated using, as a flowability of the powder, an adhesive force of the powder calculated from a failure envelope obtained by a shear test. The shear test is conducted by a powder rheometer, and the adhesive force is obtained from the relationship between a normal stress and a shearing stress at the powder rheometer. If the adhesive force is 0.450 kPa or less, the powder is evaluated to be spread into a uniform powder layer in the lamination shaping. Furthermore, if at least one of that the 50% particle size of the powder obtained by a laser diffraction method is 3 to 250 ?m and that the apparent density of the powder is 3.5 g/cm3 or more is satisfied, the powder is evaluated to be spread into a uniform powder layer in the lamination shaping.

  • Patent number: 11202996
    Abstract: A filtration filter comprises a metallic mesh having a circumferential shape and radially inner and outer portions. The metallic mesh is adapted to filter out a filtration target object contained in a fluid passing through the membrane. First and second frame members hold the outer portion there between so as to create first and second bent sections separated by a transition section extending between the first and second bent sections. The transition section includes at least one streaked projection.

  • Patent number: 10858624
    Abstract: A filter for filtering nucleated cells that includes a body containing at least either a metal or a metal oxide as its main component; and plural through holes, each of which have a shape other than a square shape, formed therein. A longitudinal diameter of an inscribed ellipse within each of the through holes is smaller than a size of a nucleus of each of the nucleated cells to be filtered. The inscribed ellipse of the through hole is an ellipse that abuts all sides that define an opening of the through hole.

  • Publication number: 20200254517
    Abstract: This invention relates to a method of evaluating a squeegeeing property of powder for lamination shaping by stable criteria. In this method, the squeegeeing property is evaluated using at least a satellite adhesion ratio of the powder and an apparent density of the powder. The satellite adhesion ratio is the ratio of the number of particles on which satellites are adhered to the number of all particles. If the satellite adhesion ratio is equal to or less than 50%, and the apparent density is equal to or more than 3.5 g/cm3, the squeegeeing property is evaluated as that the powder can be spread into a uniform powder layer in the lamination shaping. Furthermore, if the 50% particle size of a powder obtained by a laser diffraction method is 3 to 250 ?m, the squeegeeing property is evaluated as that the powder can be spread into a uniform powder layer in the lamination shaping.

  • Patent number: 10010974
    Abstract: Disclosed is a technique for quickly detecting a defect of a portion welded by laser beam welding. Specifically disclosed is a welding step in which a welding device is used, the welding device welding an object to be welded with a pulsed laser. In the welding step, a first photodetector receives only infrared rays having a wavelength allowing detection of a keyhole formed in a molten pool from among infrared rays radiating from a welded portion during the welding of the object, and an analyzer determines quality of the welded portion on the basis of intensity of the infrared rays received by the first photodetector.
