Abstract: A building material is formed from a specific composition containing a phosphoric ester compound represented by the following formulae (8)-c and (8)-d and copper ions, in a resin plate.

Abstract: A pharmaceutical composition containing 24,25-dihydroxycholecalciferol is provided. The active ingredient used in the present invention is an intrinsic and safe substance, and so does not exhibit hypercalcemia which is the side effect induced by conventional antirachitic agents, and is effective for the treatment of rickets, particularly vitamin D resistant rickets.

Abstract: Food packaging-use formed articles including at least one layer of a 3 to 90 microns thickness which comprises a composition consisting of polyvinyl alcohol resin having a degree of saponification of 60 to 95 mole % (A) and a compound elected from a group of alkylene glycol polymer, etc. falling within the range of from 3 weight parts of (B) to 100 weight parts of (A) to the saturated solubility of (B) in (A) and having a carbon dioxide/oxygen solubility ratio (SCO.sub.2 /SO.sub.2) of 30 or higher.

Abstract: A material testing apparatus including holders for material to be tested, a driving unit actuating the holders to plastically deform the material and a measuring unit for measuring the extent of color changes in deformed material. The measuring unit, which is an essential part of the apparatus, includes a light source, a light beam receiving unit and a display device. Light beams emitted from a light source are reflected on the plastically deformed material in the form of a testpiece, and thus reflected light beams are introduced into the light beam receiving unit in which the intensity of the received light beam is detected. Then, the light beams are converted into an electrical value, and digitally displayed on the display device. The driving unit may include a mechanism for changing the rate of deformation of the material. The material is usually subjected to plastic deformation by a stepping motor which changes the rate of deformation of the material.
