Dear Mr. Murakami:

      We have reviewed your response letter dated July 28, 2005
and
have the following additional comment.


Form 10-K for the year ended December 31, 2004


Segments, Prior Comment 7
1. You state that the Poz-Loc Traffic Systems are not considered a
reportable segment because discrete financial information is not
available.  It is unclear to us how you are able to make decisions
concerning the allocation of resources to this business, or to
assess
its performance in the absence of discrete financial information.
You say that you combine the information of Poz-Loc Traffic
Systems
with Tubular Products. Please provide us with the pre-combined
information for Poz-Loc Traffic Systems. We assume that as part of
your normal internal control structure you require information to
assess this ongoing business. Provide us with an example of your
internal management reports for the Tubular Products.

We also note that the nature of Poz-Loc products is different than
that of other Tubular products, requires specific and differing
government approval and is sold through different marketing
channels.

You say that you do not consider Propane Tanks to be a reportable
segment as it does not meet the quantitative thresholds of
paragraph
18. However this does not mean that it, or Poz-Loc, may be
aggregated
with another reportable segment unless it meets all of the
aggregation criteria in paragraph 17. Considering the nature of
the
products, it does not appear that they meet such criteria.
