Title:

ADJUSTING METHOD OF HEAT DISSIPATION CONSTANT

Document Type and Number:

Japanese Patent JP3245687

Kind Code:

B2

Abstract:

PURPOSE: To adjust heat dissipation constant of temperature-sensitive element by building the temperature-sensitive element into a bridge circuit of a sensor and then energizing the circuit.
CONSTITUTION: A temperature-sensitive element 4 is suspended in a container TO-5 by means of lead wires 5, 5 connected with hermetic terminals 6, 6. Since heat dissipation constant of the temperature-sensitive element 4 varies depending on the distance between the suspended temperature-sensitive element 4 and the container, it can be adjusted arbitrarily by partially deforming the container mechanically thereby varying the distance between the temperature-sensitive element 4 and the container. When two samples having different heat dissipation constants are built in a bridge circuit and output voltage from the bridge circuit is regulated to zero by deforming the container for a sample having lower terminal voltage partially inward, heat dissipation constants for both samples can be matched.
