Abstract: Novel carbapenem compounds, which are shown by the formula (I): ##STR1## wherein R is --SO.sub.3 H or hydrogen, or a physiologically acceptable salt thereof, are useful as a bactericide or disinfectant, and also produce a synergistic effect with penicillin and/or cephalosporin antibiotic agents.The compound of the formula (I) can be produced by subjecting to reduction reaction a compound of the formula: ##STR2## wherein R has the same meaning as defined above, or a salt thereof.

Abstract: Novel tetrapeptidehydrazide derivatives, inclusive of a pharmacologically acceptable acid addition salt thereof, which has the general formula (I): ##STR1## [wherein R.sub.1 is hydrogen or lower alkyl; R.sub.2 is hydrogen or the side chain of a D-.alpha.-amino acid; R.sub.3 is hydrogen or lower alkyl; R.sub.4 is hydrogen, or a saturated or unsaturated and straight or branched lower aliphatic acyl group which may optionally be substituted by hydroxy, amino, lower alkoxy, halogen, oxo, lower alkylthio or lower alkylthiooxide], are useful as analgesics.

Abstract: A ferritic precipitation-hardened soft magnetic stainless steel is disclosed. This steel consists by weight percentage of not more than 0.1% of C, 12.0-22.0% of Cr, 1.5-6.0% of Nb, at least one of Al and Ti, provided that an amount of Al used alone is 0.5-4.0%, an amount of Ti used alone is 0.5-3.0% and an amount of Al and Ti used together is 0.5-4.0% (in the latter case, the amount of Ti does not exceed 3.0%), the remainder being Fe and incidental impurities. The steel exhibits substantially 100% ferrite phase after solution heat- and aging-treatments and has improved magnetic properties, corrosion resistance and hardness.
