    摘要: The present invention provides a method to cure material (polymer, metals) into a mold against the shape of a fluid (aka the substrate). The substrate is a ferrofluid, and its shape can be dictated by surrounding magnetic fields. By manipulating the applied magnetic fields, the ferrofluid can be formed into a specific shape; then, the curing material (in fluid or powder form) can be molded against that specific shape. The ferrofluid shape can further be changed during the curing step to impact the final shape. The methods of the present invention permit fast three-dimensional molding in a programmable fashion.

    摘要: A method of producing a copper-base sintered bearing material is provided so that it is sintered with high thermal efficiency. As a heat source for a sintering furnace, an electric resistance heater which heats a furnace atmosphere and/or a high frequency induction heater, is provided, and also a microwave oscillating device which irradiates microwaves to copper alloy powder to be sintered is provided therewith. A steel sheet, which is a steel backing metal, can be heated by an electric resistance heater and/or a high frequency induction heater, and the copper alloy powder can be heated directly by microwaves.
