Abstract: There is provided a die plate, a resin machine, and a method of heating nozzles of the die plate that can suppress temperature unevenness of the nozzles and increase the temperature rise performance of the nozzles. The die plate includes a nozzle group including a plurality of nozzles through which molten resin passes, and a heating medium guidance part that guides a heating medium for heating a nozzle wall of each nozzle. The heating medium guidance part includes an inlet that receives the heating medium, an outlet that discharges the heating medium from a heating medium channel, and a guidance wall that defines a heating channel that causes the inlet and the outlet to be in communication with each other together with an outer peripheral surface of the nozzle wall of each of the plurality of nozzles.

Abstract: A method for manufacturing an additively-manufactured object incudes a groove portion processing step, a groove portion closing step, and a building step. In the groove portion processing step, a groove portion is formed by cutting an outer periphery of the shaft body. In the groove portion closing step, a first weld bead is formed along the groove portion on an edge portion of the groove portion in a shaft body to close the groove portion to form a hollow portion. In the building step, a built-up portion is built by depositing a second weld on the outer periphery of the shaft body.

Abstract: A method is disclosed for dividing a composite material in which a brittle material layer and a resin layer are laminated, including: irradiating the resin layer with a laser beam L1 oscillated from a CO2 laser source along scheduled dividing lines DL of the composite material to form a processing groove along the scheduled dividing lines; and irradiating the brittle material layer with a laser beam L2 oscillated from an ultrashort pulsed laser source along the scheduled dividing lines to form a processing mark along the scheduled dividing lines. In the resin removing step, in a region IS where the scheduled dividing lines intersect, the laser beam oscillated from the CO2 laser source is not irradiated multiple times, or an irradiation amount of the laser beam is decreased relative to an irradiation amount in a region other than a region where the scheduled dividing lines intersect.

Abstract: A decorative molded body (1) comprises: a transparent layer (10) having an exposed surface (11) and an uneven back surface (12) on an opposite side of the exposed surface (11); a molded layer (50) disposed to face the back surface (12) of the transparent layer (10); a decorative film (30) formed in a predetermined contour shape, disposed to be sandwiched between the back surface (12) of the transparent layer (10) and the molded layer (50), and formed to follow an unevenness of the back surface (12) of the transparent layer (10), the decorative film (30) being visible through the transparent layer (10) from the exposed surface (11) of the transparent layer (10); and a sealing member (60) disposed in a periphery shape on an outer periphery side of the decorative film (30) and burying an outer periphery edge of the decorative film (30).

Abstract: The disclosure provides a method for manufacturing a decorative molded body and a method for manufacturing a processed product using the decorative molded body. The method for manufacturing the decorative molded body includes: a film preparation step of molding a decorative film in a planar shape; a molding preparation step of, in a mold, disposing a transparent layer as an insert and disposing the decorative film of the planar shape; and a film forming step of, while supplying in the mold a material of a molded layer and molding the molded layer, forming the decorative film to follow an unevenness of a back surface of the transparent layer.

Abstract: The vibration of a cab deck as well as the mass of a deck supporting member is suppressed. A slewing frame of an upper slewing body includes a front plate connected to a second side plate. A cab deck is disposed on a front side of an engine deck with a gap between the cab deck and the engine deck. A deck supporting member is connected to the second side plate and the cab deck. When viewed along an up-and-down direction, a connection portion of the front plate to be connected to the second side plate is opposed to, in the lateral direction via the second side plate, a connection portion of the deck supporting member to be connected to the second side plate.

Abstract: The vibration of a cab deck as well as the mass of a deck supporting member is suppressed. A slewing frame 10 of an upper slewing body 1 includes a front plate 17 connected to a second side plate 15B. A cab deck 30 is disposed on a front side X1 of an engine deck 20 with a gap S between the cab deck 30 and the engine deck 20. A deck supporting member 40 is connected to the second side plate 15B and the cab deck 30. When viewed along an up-and-down direction Z, a connection portion of the front plate 17 to be connected to the second side plate 15B is opposed to, in the lateral direction Y via the second side plate 15B, a connection portion of the deck supporting member 40 to be connected to the second side plate 15B.

Abstract: To provide a method for manufacturing a composite member including an aluminum die cast member and a polymer member firmly bonded by removing a carbide film on the surface of the aluminum die cast member to even the surface layer. The method includes: a melting step of melting a surface layer of a joint surface of the aluminum die cast member by irradiating the joint surface with a laser, the joint surface being joined with the polymer member; and a combining step of integrally molding a polymeric material on the joint surface. The method may have a removal step of removing the carbide film present on the joint surface by irradiating the joint surface with the laser before the melting step, and a modification step of irradiating the joint surface with plasma to impart a hydroxyl group to the joint surface after the melting step.

Abstract: A detecting unit detects a first output signal and a second output signal, which are output by a first sensor and a second sensor disposed on an actuator, and outputs a first detection signal and a second detection signal to a measurement unit. Based on the first detection signal and the second detection signal, the measurement unit measures a tact time taken for a piston to move from one end to another end of a movement range.
