TAO TIMEPIECE DEVICE ABLE TO SIMULTANEOUSLY CLOCK AND DISPLAY ANALOG CLOCKING, DIGITAL CLOCKING AND ABSOLUTE TIME

摘要

PURPOSE: To dissolve even sight clocking error (l/100,000,000 second) by uniting sandglass system clocking devices and a 360° rotating system clocking system on one device. ;CONSTITUTION: Six pieces, for instance, of sandglass system devices A-F are prepared, and these six pieces are integrated onto a 360°C rotating system device, with each constricted place at the center as a cardinal point. This results in realizing a timepiece device in which six sandglass system timepiece devices with twelve vertical closed spaces are integrated on the 360 rotating system timepiece device, divided into twelve equal parts, as a base body. As a result, the integrated time of the elapsed time until the set time, and the subtracted time indicating the residual time obtained by inverse operation from the set end time can be both displayed simultaneously, and can be displayed with no time error at all, if necessary. If the number of the sandglass system devices is (n), the 360° rotating system device can set any time dividing form by dividing 360° into 2n equal parts.;COPYRIGHT: (C)1995,JPO
