The increments of the light in the "Translucent Tranquilizer" 
are controlled by the mathematical dictates of an exponential curve.
An exponential curve can express a physical phenomenon in nature.
For example,when we place a metal ball on a waterway,which has a 
smoothed bottom and is filled with continuously flowing water,
we can see the velocity of the metal ball,reflected in an air-tight
container is also reflected by the same curve.
The controlled light of the "Translucent Tranquilizer" is like 
respiration.
I think there is a reason that there are many
 "exponential curved phenomena" inside our bodies.
The cycle was set a 1/3 or 1/4 of the breathing rate for a human being 
at rest.
I expected to cool down our mental conditions,like taking "Tranquilizer".
This rhythm is created by an analog-circuits.
Analog-circuits were once regarded as an old fashion-expensive and
 inaccurate.
As the rhythm  varied under the influence of temperature,humidity and 
supplied voltage,it is perfectly suitable for expressing of
 "Tomoko NINOMIYA's world",which is quiet and cool,but warm.
