[ Problem Point ]

We were looking for a heater that would synchronize with the pulse signal.

[ ⇒Kaizen Point ]

By changing the applied frequency, it was possible to limit the area of the heat generation point.
When applied in a low cycle, a large temperature change was observed and a large region was visible.
High cycle application could be limited to a small area.
Then, by changing the applied voltage, the heat generation state could be changed.
Furthermore, by using a cold air cooler together, the cooling cycle could be controlled.
