摘要： An injection molding machine capable of continuously injecting a molten resin is provided. An injection molding machine including: a plurality of cylinders; a plurality of pistons configured to extrude the molten resin inside the respective cylinders; a plurality of drive parts configured to drive the respective pistons; an injection part configured to inject the molten resin extruded from the plurality of cylinders; and a controller configured to control the plurality of drive parts. The controller controls the plurality of drive parts in such a way that a period during which the molten resin is injected from a first cylinder overlaps a period during which the molten resin is injected from a second cylinder and the molten resin is continuously injected from the plurality of cylinders.

摘要： A first metal powder is supplied to a substrate to form a beginning part of a clad layer. After the beginning part is formed, the second metal powder is supplied to the substrate. A concentration of at least one of Si, Ni, Mo, and Al in the first metal powder is lower than a concentration thereof in the second metal powder.

摘要： A wear-resistant member production method includes: forming a clad layer by moving, relative to a substrate while feeding cladding powder onto the substrate and melting it using a local heating device; and cutting the clad layer. The cladding powder includes matrix powder containing a copper-based alloy, and hard powder including, as a hard phase, a silicide containing one or more elements selected from Cr, Fe, Co, Ni, and Cu, and one or more elements selected from Mo, W, and Nb. The hard powder includes first hard powder and second hard powder. The second hard powder is fed, separately from the first hard powder, to a melt pool formed by melting the first hard powder and the matrix powder, such that at least part of the second hard powder remains unmelted within the clad layer.

摘要： An intake port of an internal combustion engine is connected to a combustion chamber and includes a connecting portion having a passage cross-sectional area that increases as the connecting portion approaches the combustion chamber, and an upstream portion connected to an upstream end of the connecting portion. The connecting portion is provided at its downstream end with a valve seat with which an umbrella part of an intake valve is brought into contact. At least one recess extending in an extending direction of the intake port and included in the connecting portion and the upstream portion is provided at least at one of two portions, the two portions located on both sides in an extending direction of an output shaft, of a peripheral surface of the intake port.
