An ingot is manufactured by pulling it up such that V/Ga and V/Gb become 0.23 to 0.50 mm2/minute ° C., respectively, where V (mm/minute) is a pulling-up speed, and Ga (° C./mm) is and axial temperature gradient at the center of the ingot and Gb (° C./mm) is an axial temperature gradient at the edge of the ingot at temperatures in a range of 1,300° C. to a melting pointy of silicon. A wafer obtained by slicing the ingot is heat treated in a reductive atmosphere at temperature in a renge of 1,050° C. to 1,220° C. for 30 to 150 minutes. A silicon wafer free of OSF's, free of COP's, and substantially free of contamination such as Fe and of occurence of slip, is obtained.

Disclosed is a process for producing a phosphine derivative from a phosphine oxide derivative, which comprises the following steps: (I) mixing a phosphine oxide derivative represented by formula (1) with a chlorinating agent in a polar organic solvent to cause the reaction between these components; and (II-1) adding a salt of a metal having an ionization tendency equal to or lower than that of aluminum to the reaction mixture and carrying out the reductive reaction in the presence of aluminum or (II-2) subjecting the reaction mixture to electrolytic reduction, thereby producing a phosphine derivative represented by formula (2). ArnR3-nP═O (1) ArnR3-nP (2) In formulae (1) and (2), Ar represents an aryl group such as a phenyl group, a phenyl group having a substituent, a heteroaromatic ring group, and a heteroaromatic ring group having a substituent; R represents an aliphatic hydrocarbon group or an aliphatic hydrocarbon group having a substituent; and n represents an integer of 0 to 3.

A solar cell construction in a display device is provided. The photovoltaic conversion can be performed with high efficiency by the solar cell construction. The display device includes a front substrate and an opposing rear substrate, which are light-transmissive. The display device further includes an optical control layer, a solar cell layer and an insulating flattened layer. The optical control layer is disposed between the substrates, wherein images formed by the optical control layer are displayed on the outer side of the front substrate. The solar cell layer is disposed in a specific area of the major surface on the rear substrate, between the rear substrate serving as a base for supporting it and the optical control layer, and receives incident light coming from the external surroundings through the rear substrate. The insulating flattened layer is formed on the solar cell layer, wherein the optical control layer is formed on and supported by the insulating flattened layer.

The present invention provides a human β-defensin secretion promoter that can be used in various forms, such as external preparation, internal preparation, food, etc., and promotes human β-defensin secretion. An organic acid has an effect of promoting the secretion of human β-defensin, particularly human β-defensin-2, and therefore the organic acid is used as an active ingredient of a human β-defensin secretion promoter. Furthermore, by adding the human β-defensin secretion promoter to external preparations, internal preparations, or foods, a human β-defensin secretion promotion effect can be imparted thereto.
