Assistant U.S. Attorney, and Robert J. Triba, Chief Counsel, Social
Security Administration, on brief for appellee.

December 3, 1999

          Per Curiam.    Having reviewed the record with care,
we find that substantial evidence supports the ALJ's decision
that claimant did not show that prior to the expiration of his
insured status he had a medically determinable impairment or
combination of impairments which precluded the performance of
his past relevant work.  We apprehend no error in the ALJ's 
evaluation of conflicting medical opinions about the claimant's
residual functional capacity, see 20 C.F.R.  404.1527(e)(2),
(f), nor in the determination that claimant had not produced
credible proof of the onset of a severe mental impairment prior
to the expiration of his insured status.  See 20 C.F.R.  
404.131(b).     
          Affirmed.  See Loc. R. 27(c).
