摘要： PROBLEM TO BE SOLVED: To analize a magnetic field source by measuring vertical components of the organism magnetic field without increasing the number of detecting coils. SOLUTION: An organism magnetic field measuring device for measuring organism magnetic field distribution in a shield room has a plurality of fluxmeters formed of quantum interference elements (SQUID) and arranged at equal spaces to detect the organism magnetic field generated from an organism 2, as a signal; an arithmetic processing means 8 for performing arithmetic processing of the signal; and a display means for displaying the arithmetic processed result. The fluxmeters detect the time change of normal components Bz, vertical to the organism surface, of the organism magnetic field. The arithmetic processing means computes to obtain the time change of the value proportional to a square sum root of the change rate of the normal components in an x-direction and a y-direction and to obtain the integrated value in a specified period of this time change and displays the integrated value on the display means. Quantitative organism magnetic field distribution is therefore displayed using a small number of figures, so that individual diseases and abnormality can be grasped objectively and quantitatively.

摘要： PURPOSE:To decrease the deformation quantity of the structure body caused by hygroscopic swelling by providing a vent hole for allowing moisture to escape on the reaction container structure body. CONSTITUTION:Reaction cells 1, 2... of the outside peripheral side and reaction cells 11, 12... of the inside peripheral side are placed like a concentric circle so as to correspond in one line to the centripetal direction, and manufactured as a reaction container structure body 10 by a mold integral formation of transparent plastic. Between the outside peripheral side and the reaction cells of the inside peripheral side, plural vent holes 21 are provided, and on the inside of the reaction cells of the inside peripheral side, as well, plural vent holes 31 are formed. On both the outside peripheral side and the inside peripheral side, two pieces of adjacent reaction cells come into contact with each other, and between those reaction cells, gaps 51, 52... are provided. The structure body 10 moves horizontally on the peripheral track in a state that the lower part of the reaction cells 1..., 11... is immersed into a constant temperature water side. Moisture generated from a thermostatic oven is emitted to the outside through the holes 21, 31. In such a way, a difference of hygroscopic swelling between the surface of the constant temperature oven side and the surface of the open air side can be reduced, and accordingly, the deformation can be reduced.
