An object of the present invention is to provide a novel medical application to regenerative medicine that uses pluripotent stem cells (Muse cells). The present invention provides a cell preparation for treating chronic kidney disease that contains SSEA-3-positive pluripotent stem cells isolated from mesenchymal tissue in the body or cultured mesenchymal cells. The cell preparation of the present invention is based on a renal tissue regeneration mechanism by which Muse cells are made to selectively accumulate at a site of kidney disease and differentiate into cells that compose the kidney by administering Muse cells intravenously to a subject having the aforementioned disease.

An image display apparatus includes a projection unit configured to project an image and a plurality of concave reflectors in which contact surfaces with optical axes of the concave reflectors with respect to the optical axis of the projection unit are disposed at different angles from one another. A first concave reflector of the plurality of concave reflectors reflects at least a portion of an image projected by the projection unit to form a first image based on the image. A second concave reflector of the plurality of concave reflectors transmits a portion of an image projected by the projection unit and reflects a portion of the image to form a second image based on the image.

Alloy powder of a composition formula Fe_(100-a-b-c-d-e-f)Co_(a)B_(b)Si_(c)P_(d)Cu_(e)C_(f) having an amorphous phase as a main phase is provided. Parameters satisfy the following conditions: 3.5 a 4.5 at%, 6 b 15 at%, 2 c 11 at%, 3 d 5 at%, 0.5 e 1.1 at%, and 0 f 2 at%. With this composition, the alloy powder has good magnetic characteristics even when it has a large particle diameter such as 90 m. Therefore, yield thereof is improved.


Provided is a photodiode having a high-concentration layer on its surface, in which the high-concentration layer is formed so that the thickness of a non-depleted region is larger than the roughness of an interface between silicon and an insulation film layer, and is smaller than a penetration depth of ultraviolet light.

Provided is a corrosion-resistant, high-hardness alloy composition, which realizes both corrosion resistance and high hardness by using a Ni-Co-Cr-Mo-based alloy and optimizing the chemical composition, heat treatment conditions and processing conditions thereof, and a method for producing that alloy composition. The alloy composition is an alloy composition comprising 15.5% by weight to 16.5% by weight of Cr, 7.5% by weight to 15.5% by weight of Mo, 0% by weight to 30% by weight of Co, 4.5% by weight to 15% by weight of Fe and 0.5% by weight to 4.0% by weight of Cu, with the remainder consisting of Ni and unavoidably included elements, wherein the crystal phase consists only of a phase and the Vickers hardness at room temperature is 500 HV or more. The alloy composition is obtained by subjecting an ingot of an alloy having the aforementioned composition to homogenization treatment for 4 hours to 24 hours at 1100C to 1300C, followed by subjecting to cold processing at a compression rate of 30% to 60% and then to aging treatment for 0.5 hours to 3 hours over a temperature range of 300C to 600C.

To miniaturize metal columns. A semiconductor device includes a metal column (14) that extends in a stretching direction; a polymer layer (16) that surrounds the metal column from a direction crossing the stretching direction; and a guide (12) that surrounds the polymer layer in the crossing direction so as to be spaced from the metal column with the polymer layer interposed therebetween. A method for manufacturing semiconductor devices includes a step of filling a mixture (20) containing metal particles (22) and polymers (24) in a guide (12); and a step of subjecting the mixture to a heat treatment so that the polymers agglomerate to the guide to form a polymer layer (16) that makes contact with the guide and the metal particles agglomerate away from the guide with the polymer layer interposed therebetween to form a metal column (14) that stretches in a stretching direction of the guide from the metal particles.
