ding)第6巻 167〜169頁)。2. Description of the Related Art A conventional thermoelectron power generation element 1'includes three emitter electrodes 2a to 2a as shown in the principle diagram of FIG.
If c is divided by a wire, the currents Ia-Ic flowing through the wire will change due to the gap in each part. This can be used to adjust the non-parallel electrodes. A change in the currents Ia to Ic flowing through the wire causes a change in temperature and a change in the length of the wire, and the change alone is sufficient to compensate for most of the non-parallelism due to manufacturing defects. Now, a gap between an emitter electrode that emits thermoelectrons, for example, the emitter electrode 2a and a collector electrode 4 that traps thermoelectrons (hereinafter, referred to as "electrode space distance").
Becomes smaller, the output current Ia of this wire increases.
As a result, the increased current Ia causes the wire to be heated more than before, and the wire expands due to thermal expansion to change the direction of increasing the electrode space distance to adjust the electrode gap (1992 edition). DINCE (IECEC Procee
