Abstract: A thermoplastic elastomer composition contains (A) to (D): (A) 100 parts by mass of a propylene polymer; (B) 50 to 300 parts by mass of an ethylene/?-olefin copolymer including units of ethylene and ?-olefin having 3 to 20 carbon atoms; (C) 50 to 280 parts by mass of a softener; and (D) 90 to 400 parts by mass of a hydrogenated product of a block copolymer including at least one block mainly including a conjugated diene monomer unit and at least one block mainly including a vinyl aromatic monomer unit.

Abstract: A solar battery is formed by forming a film of a specific merocyanine dye on an n-type semiconductor substrate thereby producing a p-n junction in the interface between the dye film and the semiconductor substrate and connecting electrodes one each to the two layers.

Abstract: A device for removal of excess water from blood is formed by having a plurality of solution chambers and a plurality of blood chambers arranged alternately, partitioning the adjoining ones of the alternately disposed chambers by insertion of semi-permeable membranes one each along the boundaries thereof and having a sorbent retained in the form of a bed inside the blood chambers, whereby the blood containing waste material and excess water in consequence of renal insufficiency is freed from such fouling substances by causing the blood to flow through the blood chambers in order for the beds of sorbent to deprive the blood of the waste material through sorption and for the high concentration solutions flowing through the adjoining solution chambers to deprive the blood of the excess water through osmosis effected through the medium of the semi-permeable membranes.
