THE CLAIMED SUBJECT MATTER
Because Appellant groups claim 3 separately from claims 1, 6 and 7 (Brief1 at § VII), our
focus will be on the subject matter of claim 1, the independent claim, and claim 3. Claims 1 and
3 read as follows:
1. A sludge removing device comprising:
a sludge trapping container for removing a sludge mixed in a molten salt-bath solution;
said sludge trapping container being made of steel, ceramics, titanium, or alloy steel of a
predetermined thickness, and having a bottomed cylindrical or bottomed polygonal tubular shape
with an open end,
said sludge trapping container including a side wall and a bottom each having a plurality
of holes defined therein and extending through the predetermined thickness,
wherein each of the holes defined in the side wall and the bottom of said sludge trapping
container comprises a tapered hole extending through the predetermined thickness and having a
diameter at an end thereof opening at an outer wall surface of said sludge trapping container, said
diameter being smaller than a diameter of an end thereof opening at an inner wall surface of said
sludge trapping container.
3. A sludge removing device according to claim 1, wherein adjacent ones of the holes are
spaced from each other by a distance which is 1-3 times the diameters of the holes.
