The present invention relates to a counter circuit and method of controlling such a counter circuit, wherein a first counting section counts in accordance witha state- cycle, and a second counting section is clocked by the first counting section.

Digital data corresponding to said analog signal is output on the basis of said lower phase signal latched by the latching section and a count result of the counting section.

The extender section is used to further divide the input signal, and is synchronized to an adjustable counter section.

The packet configuration may include an OFDM signal symbol which further includes a data rate section and a data count section.

The header including a five-byte head-check section, a four-byte data-count section, a four-byte play-mode section, and a 255-byte spare section.

The slug feeder (B) includes a slug converyor (10) and a slug metering section (12).

A counting section (104) counts the waiting words included in the inputted speech and the selected waiting words.

The size of the slug may be easily adjusted by providing an adjustable metering block (124) carried in the metering section which moves in and out of the conveyor path of the articles to meter the number of articles in a slug.

A usable remaining amount counting section (124) determines a usable amount of gas in accordance with the readout data on the usable amount of gas and a flow rate determined by a flow rate calculation section (110).

A sync controller circuit receives an output from the counter section, as well as a timing signal from the extender, and generates the mode signal on the mode command line.
