摘要： In a method for manufacturing a rotor, each magnetic steel sheet has protrusions on its one surface and has recesses on the other surface at positions corresponding to the protrusions. The plurality of magnetic steel sheets are joined together as the protrusions of each magnetic steel sheet are fitted in the recesses of its adjoining magnetic steel sheet. A shaft member is inserted into a rotor core in the same direction as that in which the protrusions protrude.

摘要： A die is supported in a die holder such as a frame or an adapter supported in a frame such that it is operational use in a material deforming operation. One or both of the die and the die holder have at least one gas passage which is substantially closed by at least part of the die. Gas such as pressurized air is directed into an end of the gas passage opposite the die via a hose connected to a gas source. If the die is broken or loose leak paths are available for the escape of gas past the die to or from atmosphere. A pressure sensor connected to the hose detects the change in pressure of the gas and the magnitude of that pressure is used to determine the die condition. Alternatively a flow rate sensor is used to detect a change in the flow rate of the gas in order to determine the condition of the die.

摘要： A composite tungsten carbide insert (B, I) with heterogeneous composition and structure has a working part (W) and a non-working part (N). The working part (W) is made of a tungsten carbide material consisting of tungsten carbide powder and cobalt powder or nickel. The non-working part (N) is made of a low density tungsten carbide material consisting of titanium carbide powder, tungsten carbide powder, and cobalt powder or nickel powder. During pressing, the tungsten carbide material for the working part (W) and the low density tungsten carbide material for the non-working part (N) are weighed and added to a steel die successively for molding and then sintering. The non-working part (N) which accounts for most of the overall product volume has low density and less material consumption, and can greatly reduce the raw material costs of the product, significantly improving the performance-cost ratio of the insert (B, I).
