    摘要： The process for preparation of and the intermediate compounds such as 1H-tetrazole-5-thiol having the formula ##STR1## wherein R.sub.1 is alkyl, aminoalkyl, acylaminoalkyl, aryl, alkoxycarbonylaminoalkyl, halogen-substituted aryl or alkylamino-substituted aryl and R.sub.2 is hydrogen or arakyl, preferably benzyl. The compound is produced by reacting a substituted thiosemicarbazide with an aralkyl chloride, subjecting the resultant compound to diazotization, and reacting the resultant compound with a Friedel Crafts catalyst. Optionally, this may be further hydrolyzed when R.sub.1 is aminoalkyl and/or converted to conventional salts.

    摘要： An evaporated fuel treating apparatus reduces blow-through of evaporated fuel components from an atmosphere port to an outside and has a fluid circulation passage which includes at one end side a first chamber containing granulated carbon or fractured carbon, and heat storage material and at another end side a second chamber containing granulated carbon or fractured carbon and not having the heat storage material. A delay diffusion chamber is disposed between the first chamber and the second chamber, which does not have activated carbon and the heat storage material therein. An adsorption amount of evaporated fuel of granulated or fractured carbon in the second chamber is set to be not less than 2 vol % and not more than 8 vol % of a total adsorption amount of evaporated fuel of granulated or fractured carbon, and a volume of the delay diffusion chamber is larger than that of the second chamber.
