            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).
