    摘要： A spindle motor comprises a permanent magnet having an outer diameter, an outer circumference, and a number of poles. A stator core is disposed around and spaced from the outer circumference of the permanent magnet rotor. The stator core has a yoke portion, a number of lengthwise extending and circumferentially spaced slots, and a tooth portion between each adjacent two of the slots. The slots are disposed in close proximity to the outer circumference of the permanent magnet rotor, and a width of each of the slots in a radial direction of the stator core is smaller than a width of the yoke portion and equal to or greater than 1/20 of the outer diameter of the permanent magnet rotor. A coil has two or less turns and is comprised of a conductor disposed in the slots of the stator core.

    摘要： An electrophoresis medium membrane comprises a planar support, a planar cover sheet, and a layer of an electrophoresis gel medium provided between the planar support and the planar cover sheet. The electrophoresis gel medium contains an aqueous polyacrylamide gel, which is prepared by cross-linking polymerization of an acrylamide compound and a cross-linking agent in the presence of water and a compound having at least one carbamoyl group as a denaturing agent (or modifier). The layer of the electrophoresis gel medium has both a predetermined gradual change (gradient) in layer thickness and a predetermined gradual change (gradient) in concentrations of the acrylamide compound and the cross-linking agent.

    摘要： A method of quantitatively analyzing an analyte contained in a whole blood sample, wherein a dry multi-layered analysis element is used. The method provides particular merits when the used multi-layered analysis element has no light-shielding layer which is interposed, in the conventional analysis element, between a coloring reagent layer and a blood cell separating layer, so that red coloring matters of blood cells are detected from the support side during the step of measuring the optical density of the reflected light. After the optical density due to coloring matters of blood cells trapped by the blood cell separating layer has reached a constant level or background density, the changing rate in optical density is measured and then the measured changing rate is converted to the corresponding content or activity of the analyte through a colorimetric operation, or the total change in optical density is measured and then the substantially constant background density is subtracted therefrom to know the change in optical density caused by a coloring dye or like material formed in the coloring reagent layer in the presence of the analyte, followed by a similar conversion operation performed on the basis of the principle of colorimetry, to determine the content or activity of the analyte.
