[ Problem Point ]
We have no idea about how to heating and cooling at the same time in line.
[ ⇒Kaizen Point ]
It made high fever air of a suitable temperature with the Air Blow Heater, projected and captured data at the time of temperature up.
Afterwards, it turned off power, cooling by the air and got data at the time of temperature-fall.
The cycle of the temperature rise and fall came by one device, so the productivity rise up.
