Title: Oily solute-adsorbing body and water-purifying device
Inventor: KONISHI YOSHIAKI
IPC: B01J20/26
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To remove efficiently by adsorbing a trace amount of an oily solute dissolved in an aqueous solvent by a method wherein a polymer of which a contact angle to water is at least a specific angle is used as an adsorbing material for adsorbing the oily solute by the affinity. SOLUTION: A hydrophobic polymer such as a polysulfone, a polyethersulfone, a polyarylate, a poly(meth)acrylate, a polystyrene, a polyethylene, a polypropylene, etc., wherein when a solid, a liquid, and a gas are brought in contact with each other, in angles made by tangents drawn to the liquid at contact points of the three phases and a solid surface, a contact angle on a side containing water as the liquid is 60 deg. or over, is used as an adsorbing material for an oily solute of trihalomethanes such as a chloroform, a bromodichloromethane, a dibromochloromethane, a bromoform, etc., according to the affinity. Thereby, the oily solute can be easily removed by adsorbing without depending on a pore distribution.

Abstract: PURPOSE:To obtain a light-weight highly efficient GaAs solar cell at a high yied rate and at a low cost, by doping Group III In at a specified concentration when GaAs is epitaxially grown on an Si crystal substrate. CONSTITUTION:On an n-type silicon crystal substrate 11, a GaAs crystal layer 13, in which In is doped at a concentration of 1X10<19>-2X10<20> cm<-3>, is epitaxially grown. A buffer layer 12 can be provided between the silicon crystal substrate 11 and the GaAs crystal layer 13. Since the In doped GaAs crystal layer is epitaxially grown on the Si crystal substrate 11, the dislocation density is decreased in comparison with a GaAs layer, in which In is not doped. When solar light is inputted into the side of a p-type electrode 7, electrons and holes are optically excited and generated in the semiconductor layers of an In-doped p-type GaAs layer 14 and the In-doped n-type GaAs layer 13. The electrons are diffused into the In-doped n-type GaAs layer 13, and the holes are diffused into the In-doped p-type GaAs layer 14, in the reverse directions. The positive and negative charges are isolated with the p-n junction, and photovoltage is generated.
