Abstract: Phase delay, amplitude and the like of sinusoidal strain (stress) are detected with high precision, and also adverse influences caused by expansion, shrinkage, stress relaxation, and creep of a sample are removed by a simple correction term by way of a mathematical method, utilizing Fourier transformation processing. A digital-to-analog converter is used for converting a signal of a detector for detecting sample strain, or displacement of the sample, a memory is connected for storing a digital output signal from the analog-to-digital converter, and a calculator is used for performing a Fourier transformation calculation on the signal values stored in the memory. Complex elastic modulus M* and loss tangent tan .delta. corresponding to the basic physical amount in dynamic viscoelasticity can be obtained with high precision by processing a response signal derived from the sample by Fourier transformation processing. Also, the measuring range of the elastic modulus can be expanded.

Abstract: A double cylinder comprises an inside cylinder around which a heater wire is wound and a cylinder disposed outside thereof, and a furnace body filled an adiabatic material. Since cool air from a liquid vaporization type cooling device is passed through a gap between the outside and inside cylinders while cooling the outside of the inner cylinder around which the heater wire is wound, and is then ejected, no air current is produced inside the inner cylinder and, consequently, there is no temperature fluctuation at the thermocouple portion in the vicinity of the sample. As a result, linearity of a line indicative of a temperature rise is improved when the temperature is raised from low temperature.
