Abstract: An objective of the present invention is to provide methods of producing human collagen molecules that are easy to isolate and purify and that have a structure substantially equivalent to that of a natural collagen molecule, wherein host cells that are transduced with a collagen gene synthesize large amounts of human collagen protein derived from a gene introduced into a high exogenous gene expression vector. Another objective of the present invention is to provide collagen molecules produced by the production methods. The present inventors discovered that a large amount of human collagen hardly contaminated with host cell-derived collagen could be produced, by selecting from various mammalian cells a host cell that has low collagen expression and introducing a collagen gene construct into a vector capable of high exogenous gene expression.

Abstract: The heat conductivity of an aluminum composite material containing a fibrous carbon material is enhanced. In order to realize this, a spark plasma sintered body having a fibrous carbon material compounded in a metal matrix powder of aluminum or the like is fabricated. At the time of fabrication, an aluminum powder serving as a matrix mother material is compounded with an Al alloy powder such as an Al-12Si powder having a melting point lower than the sintering temperature of the mother material. During the process of sintering the aluminum powder, the Al alloy powder is melted, whereby the heat conductivity between the aluminum powder particles and between the aluminum powder particle and the fibrous carbon material is improved.

Abstract: A vehicle impact attenuator that can be installed at low cost in a narrow installation space, immediately stop a colliding vehicle, and effectively mitigate the impact on the vehicle. The vehicle impact attenuator includes a shock absorber that deforms upon a collision by a vehicle to reduce the impact on the vehicle. A support is provided for the shock absorber and a holding portion holds the support (20A) in a vertical position in an installation area. The support has cuts made in it that upon application of a load equal to or exceeding a set value, fracture and function as a release mechanism to thereby release the support from being held in a vertical position in the installation area. The support is deformable by a load less than the set value.
