    • A heat flux type differential scanning calorimeter has a heat reservoir made of a thermal conducting material. A thermally conductive plate is disposed in the heat reservoir for supporting an unknown sample and a reference sample symmetrically with respect to a center of the reservoir. A thermally conductive support member is disposed in contact with the thermally conductive plate and supports the thermally conductive plate in the heat reservoir. A heat buffer plate is disposed between the thermally conductive support member and the heat reservoir so that the thermally conductive support member and the heat reservoir are contacted only through the heat buffer plate.

    • The invention comprises a DC motor and a mechanism for converting a rotational motion of the DC motor to a linear motion in a vertical direction; a jig driven by the DC motor for performing sealing of a sample container; a DC power source; a section for controlling power supplied from the DC power source to the DC motor; a circuit for detecting a value of current flowing from the DC power source to the DC motor; a section for setting a predetermined load to be applied to the jig when the sample container is sealed by the jig; and a comparator connected to the load setting section and the current value detecting circuit. The comparator compares a target value corresponding to the predetermined load value set in the load setting section, and an actually measured value detected in said current detecting circuit, with each other, and an instruction is issued to the DC motor controlling section when the actually measured value detected by the current detecting circuit exceeds the target value corresponding to the predetermined load value. The instruction controls the jig drive. The arrangement allows the load on the sealer robe accurately controlled without resorting to an expensive load cell or the like.

    • A thermal analysis instrument which is equipped with a cooling mechanism and device for blowing a drying gas so that when low temperature are being measured moisture is prevented from condensing on the upper end surface of the heating furnace and on a cover that closes the inside of the heating furnace to thereby prevent deposition of frost. Where a robot mechanism is added to this thermal analysis instrument equipped with the cooling mechanism, it is not necessary to impose additional functions on the robot mechanism. The device for blowing a drying gas presents an annular passage mounted near the upper end surface of the heating furnace for blowing the drying gas against the upper end surface and the cover to thereby prevent the deposition of frost.

    • A cooling device provided in a thermal analyzer to cool a heating furnace by heat exchange between a cooling medium and the heating furnace based on direct and uniform gas-to-solid contact, and constructed to facilitate replacement of a sample in the cooled furnace. The cooling device includes a jacket surrounding the heating furnace to define a closed annular space, an inlet formed to introduce cooling medium into the closed space, and an outlet formed to discharge the introduced cooling medium from the closed space. Cooling of the furnace is carried out due to the heat exchange between the cooling medium and the heating surface in the closed space. A top portion of the heating furnace is not covered by the jacket, but is exposed to thereby facilitate the replacement of a sample through the exposed top portion of the heating furnace.
