Abstract: There is provided a magnet manufacturing method with which a high residual magnetic flux density is obtained without using dysprosium (Dy) and without using a bonding agent. Magnetic powders made of a hard magnetic material formed of a R—Fe—N compound containing a rare earth element as R or formed of a Fe—N compound are used. In a pressurizing step, the magnetic powders are pressurized by molds multiple times to form a primary compact. In a baking step, a secondary compact is formed by heating the primary compact in an oxidizing atmosphere at a temperature lower than a decomposition temperature of the magnetic powders to bond together the outer surfaces of the adjacent magnetic powders with oxide films formed on the outer surfaces of the magnetic powders.

Abstract: An injection moulding machine makes a long fiber length of reinforcing fibers contained in a resin moulded article to produce a high strength, rigidity, and wear and fatigue resistant resin moulded article. In a screw fiber kneading stage in an injection moulding machine, a longitudinal cross-sectional area between first flights feeding a base resin and reinforcing fibers in a feeding direction in conjunction with rotation of the screw while suppressing passage of the base resin and the reinforcing fibers is made greater at an upstream side than a downstream side in the feeding direction. In an article production method, an elongated roving containing the reinforcing fibers is continuously supplied as it is in the elongated state to the base resin plasticized inside the cylinder of the injection moulding machine to prepare a fiber-reinforced resin and the prepared fiber-reinforced resin is made to fill a mould internal space of a mould.

Abstract: A hard magnetic material formed of material powders made of a R—Fe—N compound containing a light rare earth element as R, or material powders made of a Fe—N compound is used as material powders. There is formed a compact in which a density of the hard magnetic material powders differs between an outer face side portion and an inside portion of the compact such that a rate of progress of powder bonding due to microwave heating is higher in the inside portion of the compact than in the outer face side portion of the compact when an outer face of the compact is irradiated with microwaves. Then, the outer face of the compact is irradiated with the microwaves to cause the microwave heating, thereby bonding the hard magnetic material powders by oxide films which are formed on the hard magnetic material powders.
