Abstract
PURPOSE: To make it possible to know tide time of various places of a country easily by equipping a keyboard, arithmetic part, memory part, and display part.
CONSTITUTION: The tide time calculator consists of keyboard 2 and display unit 3 arranged on the face of case 1, and memory 4 as a memory part and microcomputer 5 as an arithmetic part installed in case 1. Memory 4 is stored with the control program of microcomputer 5 and various data (reference data, reference tide time at a reference place at the reference date, tide-time revision numbers between the reference place and specific places, and the age of the moon at the reference date) needed to calculate the tide time. Further, ten-digit numeric keys on keyboard 2 are used for the assignment of a desired date when the tide time is to be found and for four rules, and character keys T, H, N... with appended abbreviations of reference places are also used to assign a desired place whose tide time is to be found.
