The first effective diameter of the central segment is gradually tapered to the second effective diameter of the offset segments across first steps.
The flange of a lens has a transitional surface outside the effective diameter.
The second effective diameters of the offset segments are gradually tapered to the diameter of the catheter shaft across second steps.
There is provided at least one sputtering head, the effective diameter of which is smaller than half the inner diameter of the sputtering vessel.
The ratio of the effective diameter of the optical fiber preform to the diameter of the assembled core rod is 2.5-5.6.
The 'parachute' structure comprises hydrophilic branched molecular fragments, or a cyclodextrin moiety, with a defined action diameter.
The first fibrous layer is a multiple component meltblown web comprised of at least 95 % by weight of meltblown fibers having an average effective diameter of less than 10 microns.
The case connect links contain out of plane bends to accommodate a change in the effective diameter of the case and the balance bar with respect to each other due to changing thermal conditions.
In the filtering apparatus, flexible fibers having an effective diameter of 1 to 60 μm and which are flexible, elastic, and have proper surface roughness extend in the longitudinal direction of the apparatus.
