Abstract

PURPOSE:To track the sun easily and surely by controlling electric contacts through thermal expansion by temperature differences of the metals of the same kind. CONSTITUTION:When the temp. of a detecting plate 1 on the left side etc. of temp. difference detecting plates 1, 1 formed of two sheets of the metals of the same kind of the tracking device rises higher, the plate 1 moves to the right direction on account of the thermal expansion of said plate 1, then the contact (c) and contact a2 of electric contacts 2 connect, thereby generating a delay pulse. One electromagnetic coil 3 is energized by this pulse, and a gear 9 is turned by a prescribed amount in the prescribed direction by way of a feed cam 6, whereby the tracking device is driven until there are no more temp. differences of both plates 1 and 1. Hence, the sun is tracked surely with the simple constitution irrespective of the change in the atmospheric temp., etc.
