2) the ledge side is made 10 five equilibriums, adjacent sector, its both sides are shared respectively, are the occasion of datum level with the edge part, this fan-shaped face constitutes 40.5～49.0 degree with respect to the angle of this datum level, and edge part is cut into the circular arc portion of each sector;
3) form 10 leg-of-mutton, every 1, the middle position of crest line becomes one side of leg-of-mutton with the line that other crest lines are connected to the point of edge part mutually, all the other both sides are leg-of-mutton adjacent shared limit, is the occasion of datum level at each leg-of-mutton with the edge part, with respect to angle formation 40.5 degree～41.5 degree of this datum level;
4) form 5 tetragonal, make the shared adjacent part leg-of-mutton, shared this limit of short brink cut into tetragonal, at bottommost, 5 tetragonal top converges, is the occasion of datum level at each tetragonal with the edge part, is 35.5～36.5 degree with respect to the angle of this datum level;
5) protruding hat side is also making 10 five equilibriums with the corresponding position of ledge side, adjacent fan-shaped face, both sides are shared respectively, at this fan-shaped face is the occasion of datum level with the edge part, angle with respect to this datum level constitutes 31.0～37.0 degree, and edge part is cut into the circular arc portion of each fan-shaped face;
6) form 10 leg-of-mutton, make every 1, the position apart from edge part 11/4 of crest line becomes one side of leg-of-mutton with the line that other crest lines are connected to the point of edge part mutually, other both sides are leg-of-mutton adjacent shared limit, is the occasion of datum level at each leg-of-mutton with the edge part, is 29.5～30.5 degree with respect to the angle of this datum level;
7) part that will become the planar portions of protruding hat side cuts into: be 55%～65% position of the diameter of edge part in the degree of depth, tetragonal of the bottommost of ledge goes up overlooking of the star that forms, and to be seen as pentagonal external diameter identical with the diameter of the planar portions of protruding hat;
8) the shared place on leg-of-mutton adjacent limit forms leg-of-mutton, and planar portions becomes decagon, and 10 leg-of-mutton is cut into tetragonal respectively, so that described planar portions becomes decagon.
