Complete electrical isolation is difficult due to the effects of eddy currents, etc., and the disadvantage is that noise is superimposed on the transmitted signal.
本発明はこのような現状に鑑み成されたもので
あり、以下本発明による信号変換素子について、
第１図および第２図の図面を用いて説明する。 The present invention has been made in view of the current situation, and the signal conversion element according to the present invention will be described below.
This will be explained using the drawings of FIGS. 1 and 2.

３ａにはリード線４が接続されている。 FIG. 1 shows a signal conversion element according to an embodiment of the present invention. In the figure, 1 is an alumina substrate as a thermally conductive insulator, and 2 is a heating element formed on one surface of this alumina substrate 1. A thick film glaze resistive film 3 is a heat-sensitive glaze film as a temperature sensor formed on the other surface of the alumina substrate 1, and this heat-sensitive glaze film 3 has a resistance value change amount with respect to temperature, that is, linearity. We use only good quality products. Furthermore, electrodes 2a and 3a are provided on the thick film glaze resistive film 2 and the heat-sensitive glaze film 3, respectively.
A lead wire 4 is connected to 3a.
なお、５は抵抗値調整溝である。 Note that 5 is a resistance value adjusting groove.

じて変化する。 That is, in the present invention, by passing an electrical signal through the thick film glaze resistive film 2, the thick film glaze resistive film 2 generates heat due to the electrical signal. The heat generation temperature at this time changes depending on the magnitude of the electrical signal.
そして、この厚膜グレーズ抵抗膜２の発熱は、

る。 The heat generated by this thick glaze resistive film 2 is
The heat is transmitted to the heat-sensitive glaze film 3 through the alumina substrate 1, and the resistance value of the heat-sensitive glaze film 3 changes in accordance with the transmitted heat. It is possible to transmit data in a completely isolated state.
この時、アルミナ基板１が大きいほど応答性が
悪くなるが、同期の長い信号や大きい信号に対し
ては良好である。 At this time, the larger the alumina substrate 1, the worse the response, but it is good for signals with long synchronization or large signals.

のである。 As described above, according to the present invention, signals can be transmitted in an electrically insulated state, and if an insulator with a small specific heat and a small shape is used, small signals or signals with a fast period can be transmitted. On the other hand, if a material with a large specific heat is used, it will be possible to transmit large signals or signals with a slow period, and it will also be possible to delay the signal.Moreover, because it has a simple structure, it can be inexpensive and small. It is possible to do so.
