Title: Temperature compensating device
Inventor: SUGIMOTO HIROSHI
IPC: G05D23/24
Filed: 1979-04-20
Abstract: PURPOSE: To ensure nearly the constant temperature with a simple constitution for the photo detector when measuring the fluorescent volume, by securing the low output for the temperature detector when the temperature of the metal plate reaches the set level to turn off the power transistor and turns on when the temperature lowers less than the set level and then repeatng these actions.  
     CONSTITUTION: With application of the power source of the fluorescent volume meter, temperature detector IC operates as the comparator to the detection temperature to deliver the outputs of H and L in case the detection temperature is lower and higher than the set level of variable resistance VR respectively. This output is applied to power transistor (TR) via resistance R 4  to control the action of the TR. In other words, the TR is turned on in the region of H, and the heat generation of the operating current raises the ambient temperature of photoelectric detector PM through metal plate MB and the cover. And when plate MB reaches the set temperature, the output of detector IC features L to turn off the TR. The TR is turned on when the temperature becomes lower than the set level. In such way, the temperature of the photoelectric detector can be kept substantially at constant level with a simple constitution when measuring the fluorescent volume.
