A method for producing a customised orthopaedic implant is provided. The method involves scanning a bone from which a diseased region of bone will be resected to obtain a three dimensional digital image of an unresected volume of bone; scanning the bone after a diseased region of bone has been resected to obtain a corresponding three dimensional digital image of a resected volume of bone; and comparing the three dimensional digital image of the unresected volume of bone to the corresponding three dimensional digital image of the resected volume of bone to estimate a volume of bone that has been resected. The estimate of the volume of bone that has been resected is used to design a customised orthopaedic implant that substantially corresponds to the configuration of the resected volume of bone, the implant being configured to substantially restore a biomechanical function of the bone. Finally the customised orthopaedic implant is manufactured and provided for insertion into the resected region of bone.

To provide a porous molding that can be used as a molding that has sufficient strength to be self-supportable even when the dimensions change due to absorbing water and that can be suitably used as a filter for removing impurities in a liquid or gas. A porous molding is achieved by sintering a mixed powder including a dried gel powder and a thermoplastic resin powder, wherein the ratio of average particle diameter d.sub.1 of the thermoplastic resin powder to the average particle diameter d.sub.2 of the dried gel powder d.sub.2/d.sub.1 is 1.3 or greater, and the difference ratio of average particle diameter d.sub.1 of the thermoplastic resin powder to the average particle diameter d.sub.2 of the dried gel powder and the average particle diameter d.sub.3 of the dried gel powder when absorbing water and swelling is (d.sub.3d.sub.2)/d.sub.1 is 4.0 or less.

A method of manufacturing a semiconductor device includes providing, in a housing, an insulating substrate having a metal pattern, a semiconductor chip, a sinter material applied on the semiconductor chip, and a terminal, providing multiple granular sealing resins supported by a grid provided in the housing, heating an inside of the housing until a temperature thereof reaches a first temperature higher than a room temperature and thereby discharging a vaporized solvent of the sinter material out of the housing via a gap of the grid and a gap of the sealing resins, and heating the inside of the housing until the temperature thereof reaches a second temperature higher than the first temperature and thereby causing the melted sealing resins to pass the gap of the grid and form a resin layer covering the semiconductor chip.

The present disclosure provides a metamaterial manufacturing method. The manufacturing method includes the following steps: (a) separately adding insulating substrate powder and at least one of wave-absorbing agent powder and metal electrode powder to thermoplastic resin, and mixing them evenly to obtain a raw material; (b) applying a coextrusion process to the raw material according to a metamaterial microstructure design, to form a microstructure unit rodlike material; and (c) configuring the microstructure unit rodlike material in a cyclic microstructure configuration manner, placing the material in an extruder, and obtaining a cyclically configured metamaterial microstructure through coextrusion by using the extruder. The present disclosure further provides a metamaterial manufactured by using the foregoing method. The present disclosure provides a method for manufacturing a ceramic-substrate metamaterial that features high efficiency, low iteration costs, and a relatively high yield rate. A thinner and more efficient wave-absorbing metamaterial is obtained.
