Title: Power supply device using solar cell
Inventor: TAKADA MAKOTO
IPC: F24S23/30
Filed: 1983-09-26
Abstract: PURPOSE:To improve the efficiency of power generation by projecting solar rays to a condenser lens having high optical transmittance to which a solar cell element is fitted, absorbing transmitted and condensed solar rays by a heat collector and generating electricity. CONSTITUTION:Solar rays 5a-5e transmit a Fresnel lens 1, and one part is absorbed to solar cell elements and contributes to power generation. One part transmits the element, and most of red and infrared rays as heat sources are absorbed to a heat collector 4. The efficiency of the heat collector 4 can further be improved by the effect of a heat insulating material because the heat collector requires no function cooling the solar cell elements 2-2<n>.

Abstract: PURPOSE:To make focusing possible and reduce a measuring time if noise of a voltage measurement is large by making a determination separately at the upper limit and the lower limit of timing when the potential at a measuring position corresponds with a predetermined potential to enlarge a measurement range. CONSTITUTION:A focusing processing means 1a gives a range of timing when the potential at a measuring position corresponds with a predetermined potential as that between the upper limit and the lower limit, and move of the range between the upper limit and the lower limit and increase/decrease of its width are performed by achieving focusing of different directions for the upper limit and the lower limit based on the signs of time change of the voltage at a measuring position. A focusing limit determining means 2a then determines if the interval between the upper limit and the lower limit is within a time range prescribed by noise of a voltage measurement and inclination of a voltage waveform at the measuring position. Focusing is thus made possible if noise of the voltage measurement is large, and measuring time can be reduced.
