薄型AGS(自動巻発電ウォッチ)の開発

概要

Some quartz watches employ an electric power generator as the energy source. Already on the market is the"AGS"brand of quartz watches which generate power from the movement of the wearer's arm. These AGS watches are being made smaller and thinner. As they become smaller and thinner, however, they also generate less power. It is necessary therefore to take steps to maintain the balance between the amount of electric power generated and the amount consumed if the watch is to be driven continuously without stopping. We had to improve the power generating performance and decrease power consumption in order to bring small, thin AGS watches to market. We previously reported the improvements achieved with respect to power-generating performance, so in this paper we will take up the issue of decreasing power consumption and discuss the development of a low-power motor.
