Abstract: A display apparatus which comprises: a substrate; a first electrode group made up of a plurality of electrode patterns which are arranged adjacent to one another on said substrate, and extend in a first extending direction; a second electrode group made up of a plurality of electrode patterns which are arranged adjacent to one another on said substrate, and extend in a second extending direction which is different from said first extending direction; and a plurality of display elements which are each formed in correspondence to the intersection point of one electrode pattern among said first electrode group and one electrode pattern among said second electrode group, wherein at least said first electrode group includes a plurality of electrode patterns which are each connected to a drive circuit at one end, and are different in length from said one end to the other end, each of said plurality of electrode patterns has a lamination structure which has a first conductor having a first sheet resistivity, and a s

Abstract: A plasma-collecting devise comprises a blood-filtering element having a blood-drawing needle and a communicating needle, a vacuum blood-drawing tube, and a contracting and expanding element connecting the blood-filtering unit and the vacuum blood-drawing tube. The device enables blood drawing from blood vessel and blood filtering continuously to obtain plasma.

Abstract: The invention provides a method of recovering filtration residues of blood which comprises filtering blood by a blood filtering device comprising a blood filtering material which is a depth filtering material and a holder which contains the blood filtering material and has a blood inlet and filtrate outlet, after finishing the filtering blood, feeding aqueous liquid to the filtrate outlet to recover the filtration residues accumulated in the blood filtering material.

Abstract: One sigmoid calibration curve is split into three parts of low concentration region represented by a high degree function, intermediate concentration region represented by an exponential function and high concentration region represented by a high degree function according to the present invention. The boundary condition of the adjacent two functions is set so that the two functions have an equal slope at the boundary point; thereby, regression functions of the calibration curves in respective regions are found. The number of standard samples for finding a calibration curve can be reduced while the calibration curve found is of high accuracy.
