Abstract: A counter with communication function allows the counts of a counting mechanism to be transmitted through a communication line such as the Internet, so that no meter reading by a meter reader is required. A CPU of a control unit checks the time given in a timer and determines whether the current time and date is the date and time to transmit counts. It drives a bar code reader when it is the date and time to transmit the counts, and the bar code reader reads the counts of a counting mechanism of a copy machine and stores it in a memory. The CPU then gives a user or a management company notice of the read counts and counter information, such as a counter number, through a communication interface, a router and an Internet network by Electronic Mail.

Abstract: A dental adhesive coating base composition comprising a copolymer represented by formula (I) or (II) in an amount of from 5 to 40 wt % based on the total amounts of the composition; and an oral composition comprising at least one of a copolymer represented by formula (I) and a copolymer represented by formula (II) in an amount of from 5 to 40 wt % based on the total amount of the composition, at least one of a phosphoric acid and tartaric acid present in an amount effective to increase the solubility of fluoride in the composition, up to an amount of 6 wt % or less based on the total amount of the composition; a fluorine-containing compound in an amount effective for dental caries prevention; and a volatile nonaqueous solvent are disclosed: ##STR1## wherein R.sup.11 represents an alkyl group having from 1 to 10 carbon atoms; R.sup.12 represents a lower alkyl group having from 1 to 2 carbon atoms, provided that three R.sup.12 groups must be the same; R.sup.13, R.sup.14, R.sup.15, R.sup.16 and R.sup.
