[0057]
Step a
As shown in Figure 5 (a), the first molding member 14 comprising a first space 16 which is open at one, placing the thermoplastic resin film 18 so as to cover the opening. Then, to fix the thermoplastic resin film 18 at the open end by a fixing member 20. Thus, the first space portion 16 of one surface 18a side of the thermoplastic resin film 18, so as to partition the space of the other surface 18b side, placing a thermoplastic resin film 18.
[0058]
The first inner mold member 14, the mold 32 is disposed vertically movable. Surface 32a of the mold 32 is substantially hemispherical convex. Mold 32, the porous body comprises a myriad of pores; that solidified to flow the medium in one direction by bundling hollow tube, for example, a hollow body hardened bundling pipe-shaped molded body; a plurality of sheets structure using a plate, for example, laminate construction was layered as stacked spaced apart a plurality of plate-flowing media through the gap; structures that formed a plurality of plate in a lattice-like or triangular shape; fibrous body solidified those fibrous; are composed of such, it is possible to supply the medium to the surface 32a of the mold 32.
The porous body sintered metal; those that have been gathered to those binder coated particulate inorganic (ceramic / metal); sintered ceramic foam metal; plastic granules were gathered particles; foam plastic organic polymer granulate ; cellular rubber; those hardened by bundling hollow fibers; metal, ceramic, plastic, hollow body hardened bundling pipe-like structures made of rubber or the like; metals, ceramics, plastics, plate-like structures made of rubber or the like cavity body was laminated a gap; and the like.
Mold 32 is provided with medium supply means (not shown) can be supplied to the medium on the surface 32a from the interior of the mold 32.
