IPC: G01N11/00
Filed: 1988-03-07
Abstract: PURPOSE:To detect a change in the viscosity of blood or the like easily, quickly and accurately, by determining a kinematic viscosity of the blood or the like from a surface temperature thetas of a sensor containing a heat absorbing/ generating body immersed into the blood or the like and the temperature thetainfinity of the blood or the like. CONSTITUTION:When a sensor of a platinum wire or the like with a resistance R is immersed into blood or the like and fed with a current (i), heat with a heating value Q is generated based on the formula I and a surface temperature thetas of the sensor corresponding to the resistance R is calculated to measure a temperature thetainfinity  accompanied of blood or the like with a resistance bulb or the like. Then, based on the formula II, a computation is performed to determine a coefficient nu of kinematic viscosity. This enables accurate detection of a change in viscosity with limited errors quickly and easily free from effect of low viscosity without requiring several times of measurement. The same results are obtained by using a temperature thetaw of the heat absorbing/generating body the sensor contains in stead of the temperature thetas or by measuring a change in heat conductivity of the surface of the sensor. In the formula, C1, C2 and C3 are constant.

Abstract: PROBLEM TO BE SOLVED: To obtain a stable resistant value and the stability of production, by adopting a sea and island structure having a combination of two kinds of rubber different from each other in solubility parameter value, in a conductive foamed elastic body and dispersing carbon black on the boundary. SOLUTION: The conductive formed elastic body formed on the outer periphery of a conductive core material has the sea and island structure by three kinds of rubber different in the solubility parameter value. It is desirable that three kinds of rubber consist of nitrobutadiene rubber(NBR), ethylene propylene diene rubber(EPDM) and the third rubber having the middle one of the solubility parameter values of these two kinds of rubber. It is most preferable that the NBR and EPDM drastically different from each other in the solubility parameter value and chloroprene or styrene-butadiene rubber is the third rubber located in the middle of the NBR and EPDM are combined. Thus, the increase of hardness accompanying the increase of the addition of the carbon black can be reduced and the blending and copolymerization ratios are adjusted to be able to maintain the stable resistance value.
