The norm closure of the algebra generated by the set <$E left { n~symbol О~lambda sup n sup k~:~lambda~symbol <174>~bold roman T~roman and~k~symbol <174>~bold roman N right }> of functions on (Z,+) was studied in [11] (and was named as the Weyl algebra). In this paper, by a fruitful result of Namioka, this algebra is generalized for a general semitopological semigroup and, among other things, it is shown that the elements of the involved algebra are distal. In particular, we examine this algebra for (Z,+) and (more generally) for the discrete (additive) group of any countable ring. Finally, our results are treated for a bicyclic semigroup.
