Abstract: The spectral transmittance of pure water and salt water solutions of various concentrations, which are important for the thermal calculation of a solar pond, is measured experimentally for ...

Abstract: A new type of the reflectors for evacuated tubular collectors (ETC) which we referred to as a Compound Circular Reflector (CCR) was designed. The reflectors allow reducing the number of tubes ...

Abstract: A new deep drawing process of sheet metals is developed to facilitate small-lot production of deep cups with large drawing ratio. In this process, unlike the conventional deep drawing method, ...
