    Abstract:  希土類磁石の高性能化のために、粉末の酸化を少なくして、粉末粒径を小さくすることが有効である。本発明の課題は、酸化の程度が低く、粉末粒径が小さい極めて活性な粉末を安全に使用できる、磁気異方性希土類焼結磁石の製造方法を提供し、かつ種々の形状の製品を能率よく生産できる方法を提供することにある。秤量・充填部41及び高密度化部42において、磁気異方性希土類焼結磁石の原料となる微粉末を所定の密度になるようにモールドに充填し、磁界配向部43においてパルス磁界により微粉末を配向させた後、微粉末をプレスすることなく焼結炉44において焼結する。この方法では量産装置の動作が単純で、囲いを小さくすることができるため、従来の大がかりなプレス装置を用いる方法で問題となっていた粉末の酸化や燃焼の危険性を排除することが可能となる。また平板状、弓形板状磁石等希土類焼結磁石の最重要形状の製品を多数個取りモールドを使用して、能率よく生産できる。

    Abstract: Structure and a method for producing very dense bodies of material from particulate materials. A particulate material is placed within an electrically conductive container. A solenoid or coil encompasses the electrically conductive container, and a large magnitude of electrical current is caused to flow through the solenoid or coil. As the electrical current flows through the solenoid or coil, large magnitudes of magnetic pressures are created upon the electrically conductive container, and the electrically conductive container is compressed, and the transverse dimension thereof is reduced. Thus, the particulate material within the electrically conductive container is very firmly compacted, and a rigid body of material is provided. Any one of numerous types of particulate material may be employed. For example, a body of electrical superconductive material of any desired size and shape can be produced by this method by the use of superconducting particulate material. A method and system for selecting various parameters which enable the material to be "over-pressure" and densified to densities in excess of 90 % of the material's maximum density is also illustrated in another embodiment of the invention. The various parameters include establishing a stand-off distance, a container wall density and thickness, a fill density and a compressibility value for the material. Once the various parameters are established and for a selected material, the material is magnetically compacted to over-pressure the material to a pressure level which exceeds the pressure applied by a wall of the container. This, in turn, enables the system and method to densify the material to densities in excess of 90 % of its maximum density.

    Abstract: A powder feed mechanism (10) for a three-dimensional printer in which a heap of powder is drawn up from a powder container to be spread across a material bed (12) rather than dropped or deposited on it. The mechanism comprises a carrier arm (26) that moves through a powder chamber (15), and a support platform (28) for carrying a heap of powdered build material. The support platform moves with the carrier arm. The carrier arm moves to a powder delivery position in which the support platform is in a transverse orientation for lying flush with the material bed. This arrangement can reduce the path travelled by the powder from the powder chamber to the material bed and give greater control over the shape of the heap of powder that is to be spread over the material bed.
