Title: Analytical element
Inventor: TSUJI TOSHIO
IPC: G01N33/52
Filed: 1991-07-09
Abstract: PURPOSE:To improve the photometric accuracy of an analytical element so as to improve the measurement accuracy of the element by forming an expanding layer of a specific fiber containing at least a binder and white pigment. CONSTITUTION:An expanding layer is formed of a fiber which contains a binder and white pigment and has such a size that can pass through a 50-mesh screen but cannot pass a 325-mesh screen. Since the expanding layer contains the white pigment, the light reflectance and photometric accuracy of the layer are improved and the quantitative analysis of components contained in a biological fluid sample can be easily and quickly performed with a spectrophotometer. In addition, since the white pigment exists in the fiber, the pigment does not fill up the holes of the expanding layer. Accordingly, even when the fluid sample contains large-sized molecules, such as albumin, etc., plugging-up of the layer hardly takes place and the fluid sample adhered to the layer in the form of a spot can be expanded. Therefore, the components contained in the biological fluid sample can be quantitatively analyzed with high accuracy and the expanding layer can contain a reagent.

Title: Method for producing resin mold coil
Inventor: TANAKA YOSHINORI
IPC: H01F41/12
Filed: 1983-09-13
Abstract: PURPOSE:To facilitate production control by a method in which a wound coil is impregnated with epoxy resin, put on a high-temperature heating plate applied with catalytic hardener, and then hardened in a drying oven. CONSTITUTION:A film 18 having desirable releasing properties is laid on the upper face of a heating plate 17, and a solution of catalytic hardener is applied over there. A coil 10 impregnated with resin is put vertically on the film 18 of the heating plate 17 and heated. The temperature of the heating plate 17 is raised so that the surface temperature of the film 18 reaches the final curing temperature of epoxy resin. When the coil 10 is heated, the epoxy resin reacts rapidly with the catalytic hardener, and the epoxy resin existing in the lower end of the coil 10 cures more rapidly than the epoxy resin in the other portion of the coil to provide a sealing layer for preventing the impregnated resin from leaking from the lower end. The coil 10 is thereafter removed from the heating plate 17 and completely hardened by a dryer.
