摘要： The metal powder production apparatus includes: a spray tank; and a plurality of spray nozzles each including a molten metal nozzle that lets molten metal flow down into the spray tank and a gas injection nozzle that injects gas from a plurality of injection holes to the molten metal flowing down from the molten metal nozzle. The sectional area A1 [mm2] of the spray tank has a value obtained by multiplying the number n (n is an integer equal to or greater than 2) of the spray nozzles by a predetermined area value c1.

摘要： A method for performing cutting machining by applying a laser beam to the surface of a base material formed from a composite material and cutting the base material to be cut out a product from the base material, a machining line, serving as a boundary between the product to be cut out and a remainder which is the base material after the product is cut out, is set to the base material before the cutting machining, and a plurality of machining paths along the machining line are set to be arranged from the machining line side to the remainder side with the machining line side as a reference. In the cutting machining, the base material is cut by repeatedly executing a laser beam application step for applying the laser beam to the surface of the base material on the basis of the plurality of machining paths having been set.

摘要： A desired shape can be easily realized, and a decrease in strength can be inhibited. A method for producing a composite material includes: an insertion step of inserting an inner member in which a second reinforcing fiber is impregnated with a resin into a space of an outer member that is formed of a woven first reinforcing fiber extending in an undulating manner, the outer member including an opening that is provided at at least one end portion and the space that communicates with the opening; and a composite material forming step of forming a composite material in which the outer member and the inner member are joined to each other by curing the resin of the inner member to join the outer member and the inner member to each other.

摘要： In an information processing device according to the present invention, a statistics estimation unit estimates a value of a state quantity by using a statistical model constructed based on values of past state quantities of a target device. A physical estimation unit estimates a value of a state quantity by using a physical model constructed based on design data of the target device. A specification unit specifies a value to be used to manage the target device from the value estimated by the statistics estimation unit and the value estimated by the physical estimation unit based on deterioration of the target device with time.

摘要： A three-dimensional additive manufacturing device is configured to emit a beam to a powder bed formed by laying a powder on a base plate to harden the powder bed selectively. A sensor is configured to detect the shape or the temperature of a surface of the powder bed or a modeling surface. A defect in laying of the powder or a defect in emission of the beam is corrected based on the detection result, before completion of forming of the next layer.

摘要： A threat coping system (10) is provided with a threat coping device (300) that copes with a coping target (30) and a control device (200) that controls the threat coping device. The control device (200) is provided with a no-coping area setting means (514) and a coping instruction means (526). The no-coping area setting means (514) sets a no-coping area (12) based on information of a no-coping target that is not to cope with. The coping instruction means (526) generates an instruction signal, that instructs the threat coping device to cope a coping target, based on the no-coping area.
