Only ground connection, is grounded after can also being connected into a lead, and multiple signal leads are independent between each other, and a signal lead is used to control
The temperature of an actuator 21 is made, according to the principle expanded with heat and contract with cold, driving is controlled by controlling the size of current of external power supply
The temperature of part 21, and then control the stroke of actuator 21.
Since heat transfer is that relative displacement does not occur between the object of different temperatures or each several part of object different temperatures
In the case of, the heat transfer process as caused by the warm-up movement of corpuscle, that is, the heat by molecule, atom or free electron
Heat transfer caused by movement.
Therefore, insulating part is respectively provided with using the both ends in driver, reaches the heat-insulating material by using low-thermal conductivity
To realize isolation transmission of the heat by heat transfer.
