IPC: G01N25/16
Filed: 1992-11-27
Abstract: PURPOSE:To absolutely prevent fusion of a specimen with a detection rod by adding a function of lifting up the rod when a coefficient of contraction of the specimen becomes higher than a predetermined value. CONSTITUTION:A softening temperature and a coefficient of contraction each being a fusion prevention condition of a specimen S, e.g. a glass, are set in a temperature setting device 12 and a signal setting device 13, respectively. When the specimen S is heated and contracts, whereby the coefficient of contraction is not lower than the predetermined one in a temperature not lower than the predetermined one, both outputs of comparators 15, 16 become H levels so that an output signal of a multiplier 17 becomes H level. At this point, the heating by a heater 3a is stopped and energizing a force coil 5a is started. An electric current in the energizing is applied in a direction so that the electric current permits the coil 5a to move downwardly relative to a permanent magnet 5b and the current level is set so that the generated force is greater than a measured weight W applied on the specimen S. As a result, a detection rod 1 is lifted up. At that time, the specimen S is in the high temperature condition so that the rod separates from the specimen without resistance, thereby preventing fusion of the specimen S with the rod 1.

Title: Constant current supply circuit
Inventor: KURASHIMA YASUMI
IPC: G05F3/24
Filed: 1988-12-17
Abstract: PURPOSE:To ensure the stable supply of a constant current by detecting the deviation of the threshold voltage of a field effect transistor FET against a set level in the form of a voltage change and correcting the gate potential of a constant current supply FET. CONSTITUTION:The deviation between the threshold voltage VT of an FET and its set level is detected in the form of a voltage change via a series circuit of an FET Q2 and an impedance circuit. This voltage change is sharply sensed by a series circuit of both FET Q3 and Q4. Then the gate potential of a constant current supply FET Q5 is corrected so that the deviation of the voltage VT is compensated against its designed value. Thus it is possible to supply a stable current as designated despite the deviation of the voltage VT. At the same time, a circuit which receives the supply of current can be actuated stably and accurately by a constant current supply circuit.
