摘要:
In a thermoelectric conversion module, each of a p-type element and an n-type element is configured by aligning a plurality of particles in series and connecting the particles to each other. Around a connection part in which the particles are connected to each other, a protrusion is protruded. The protrusion has a shape of continuously extending around the entire periphery of the connection part. The protrusion may be partly interrupted, but in such a case, a circumferential length of one interrupted portion is less than one half of the periphery of the connection part.
摘要:
It is an object of the present invention to provide: a foaming mold having a high expansion ratio and a light weight and having an excellent appearance with no surface roughness; and a method for producing a foaming mold, whereby even in the case of using thermally expandable microcapsules for injection molding, the thermally expandable microcapsules can expand uniformly to give a foaming mold having a high expansion ratio and an excellent appearance.The invention is a foaming mold having uniform and closed cells, which has a cell diameter of 60 to 120 a specific gravity of 0.6 g/ml or less, and a surface roughness of 4 μm or less.
