Title: Adjusting method of heat dissipation constant
Inventor: SATO TSUTOMU
IPC: H01C7/04
Filed: 1992-05-15
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.

And after the shaping process, many tests are performed as a product and the data obtained at the tests are regarded as formal ones. The transformers passed such the shaping process will minimize a variation in coil impedance even if a high current flows in a coil by the accidents during operation. In this way, the characteristics of an electrical machine such as a transformer or the like will be stabilized and maintained.
