PURPOSE:To enable all time pieces to indicate the same time perfectly by arranging a transmission system for converting the counting of a time into a radio wave at a time announcing station and a receiving system for indicating the time. CONSTITUTION:A transmission system is composed to convert the counting of a time into a radio wave (other means of transmitting signals through space) at a time announcing station where the local time continues ticking. The transmission system is so arranged to transmit the radio wave throughout the country. For example, in the radio wave, a frequency range made uniform throghout the country is secured including partial utilization of frequency other than that currently used for TV, radio, wireless and other systems. Then, a receiving system (time piece) is arranged to incorporate a receiving function by a mercury (solar) battery and a function for converting radio waves into a mechanical or digital indication. This also has a function of acting as a time piece with an ordinary accuracy in an area unable to receive radio waves. |
