Abstract: A 6-quinazolinesulfonyl derivative of Formula (I): ##STR1## wherein R.sub.1 is a hydrogen atom or a C.sub.1-12 alkyl group:R.sub.2 is a hydrogen atom, a C.sub.1-12 alkyl group, a C.sub.4-10 cycloalkyl group, an aryl group or an aralkyl group; andR.sub.1 and R.sub.2 may be linked directly or through an oxygen atom to form a 5- to 7-membered heterocyclic ring together with the adjacent nitrogen atom; andR.sub.3 is a ##STR2## group wherein R.sub.4 is a C.sub.1-8 alkyl group; a --HN(CH.sub.2).sub.n NH.sub.2 group wherein n is an integer of 2 to 10; or a ##STR3## group; and the pharmaceutically acceptable salt thereof; and a process for the preparation thereof. The compounds of this invention have a relaxatory action for vascular smooth muscle and are useful as a vasodilator and a hypotensor.

Abstract: This invention relates to a method of producing a dam comprising the steps of exposing transmission members 4 by stripping the sheath 3 of a communication cable, covering the exposed portions of the transmission members 4 with a mold 5 and injecting self-curing resin 2 into the mold 5 to cure it. A resin which is cured while being foamed is used as the self-curing resin. The resin 2 is foamed in the mold after being injected into the mold while it is still not foamed. The resin 2 has the pressure increased by increasing the fluidity resistance of the resin 2 as it progresses to be cured when the resin 2 intrudes into gaps between the transmission members 4 within the sheath 3, which is caused by an expansion of volume of the resin 2 during foaming whereby the resin 2 is cured under a high pressure.
