Abstract: The glass panel and funnel of a color TV picture tube are sealed to one another at 420.degree. C. within 20 minutes, using a composition which includes:(a) 93-99.8 weight percent PbO--B.sub.2 O.sub.3 --ZnO devitrifiable glass powder made of:74-82 weight percent PbO,7-10 weight percent B.sub.2 O.sub.3,8-12 weight percent ZnO,1-4 weight percent SiO.sub.2,0.05-0.5 weight percent MgO,0.1-0.5 weight percent BaO, and0.1-0.5 weight percent F;(b) 0.1-4.0 weight percent synthetic zircon having a specific surface area of 1.0-2.0 m.sup.2 /g, as a nucleating agent; and(c) 0.1-3.0 weight percent corderite, as a filler.

Abstract: The present invention relates to optical isomers of quinoline compounds of Formula (IA) or Formula (IA'), their pharmaceutically acceptable salts and their intermediates: ##STR1## In the above formulae, A represent nitrogen or ##STR2## in which Y represents hydrogen, halogen such as fluorine or chlorine, lower alkyl or lower alkoxy such as methoxy, or together with R.sub.1 forms --CH.sub.2 CH.sub.2 CH.sub.2 --, --CH.sub.2 CH.sub.2 CH(CH.sub.3)--, --OCH.sub.2 CH.sub.2 --, --OCH.sub.2 CH(CH.sub.3)--, --SCH.sub.2 CH.sub.2 -- or --SCH.sub.2 CH(CH.sub.3)--;R.sub.1 is as defined above or represents straight chain or cyclic lower alkyl group having 1 to 3 carbon atoms, a straight chain or cyclic lower alkyl group having 1 to 3 carbon atoms which is substituted with a halogen atom, a phenyl group or a phenyl group substituted with one or two halogen atoms, such as ethyl, cyclopropyl or 2,4-difluorophenyl;R.sup.

Abstract: There are sintered Bi.sub.2 Te.sub.3 -based thermoelectric materials containing Ag.sub.2 S, which prevent p- to n-type transition of Bi.sub.2 Te.sub.3 -based thermoelectric materials during polycrystalline sintering and have improved thermoelectric properties.
