Title: Solar cell module having overvoltage preventing element and solar light power generating system using the same
Inventor: TAKEHARA NOBUYOSHI
IPC: H01L31/04
Filed: 1999-11-10
Abstract: PROBLEM TO BE SOLVED: To eliminate specific means for heat radiation of overvoltage preventing elements by connecting the overvoltage preventing elements in parallel for each photovoltaic element, by making the overvoltage preventing elements semiconductive, and by making the minimum operating voltage of the overvoltage preventing elements less than the open voltage of the photovoltaic element and more than the optimum operation voltage. SOLUTION: Overvoltage preventing elements 902 are connected in parallel for each photovoltaic element 901, and overvoltage is prevented by controlling the open voltage of the photovoltaic element 901. In the case the minimum operating voltage where overvoltage preventing function of the overvoltage preventing elements 902 is carried out is extremely lower than the optimum operating voltage of the photovoltaic element 901, an output loss of a solar cell is increased. Therefore, the minimum operating voltage of the overvoltage preventing elements 902 is made to be more than the optimum operating voltage of the photovoltaic element 901 and less than the open voltage.  The minimum operating voltage of the overvoltage preventing elements 902 can be controlled by a kind, a number and so on of constituting elements of the overvoltage preventing elements 902 properly selecting corresponding to the output property of the photovoltaic element 901.

Abstract: PURPOSE:To enable formation of a conductive pattern to a mold board without taking much time by forming a circuit pattern to the mold board with a trench whereto solder can be immersed through capillary phenomenon, by immersion the mold board into a solder bath and by making the solder immersed inside the groove of the circuit pattern. CONSTITUTION:An electronic parts 14 and 16 are mounted on a mold board 10. Resist is attached to an area of the mold board 10 excepting a circuit pattern 12 to avoid solder thereon. Then, the mold board 10 is reversed, and if it is immersed into a solder bath, solder is immersed into a trench of the circuit pattern 12. Since resist is attached to an area of the mold board 10 excepting the circuit pattern 12, the solder does not mount on an area excepting the circuit pattern 12. The solder is thereby filled inside the trench of the circuit pattern 12 and a conductive pattern is formed to the mold board 10. In this way a conductive pattern can be formed readily without taking much time.

Abstract: PROBLEM TO BE SOLVED: To display the shift tendency of a peak wavelength of the fluorescence intensity generated from a measured site irradiated with excitation light as an information source for estimation of tissue properties by observer. SOLUTION: An excitation light L2 from GaN semiconductor laser 114 is irradiated on the biological measurement site 10 and the generated fluorescence L3 is received via an image fiber 103 by a CCD image sensor 125 with an on- chip mosaic filter 123 composed of filters with transmission wavelength band about 480 nm and about 500 nm respectively. A1/A2 computing section 128 calculates the ratio of the light intensity A1 near 480 nm and the light intensity A1 near 500 nm A1/A1 for each image element of the CCD image sensor.  The comparison section 131 compares A1/A2 with a reference value RA previously decided based on the fluorescence from a normal tissue and a diseased tissue and displays the compared results deciding that if the A1/A2 is larger, the peak wavelength shifts toward the peak wavelength of fluorescence from the normal tissue and if smaller, it shifts toward the peak wavelength of diseased tissue.
