Title: Temperature detecting circuit
Inventor: KARASAWA KUNIHIKO
IPC: G01J5/20
Filed: 1990-11-08
Abstract: PURPOSE:To enhance the accuracy of temperature detection by delivering a difference between two reference voltages generated when a constant current is fed to diodes from a subtracting circuit. CONSTITUTION:A reference voltage Vt1B which is generated when a constant current is fed to diodes 12 through 14 from a constant current source 8, is applied to a positive input of an operational amplifier 1 through the intermedi ary of a resistor 4, and a reference voltage Vt1A which is generated when a constant current is fed to diodes 9 through 11 from a constant current source 7 is applied to a negative input thereof through the intermediary of a resistor 3. An output from the operational amplifier 1 cancels the temperature characteristics of a reverse saturated current is and a constant current value I<1>, and thereby an output voltage Vout<1> becomes proportional to an absolute temperature T. Further, a variation in the output voltage Vout<1> with respect to temperature can be set optionally by changing the gain alpha of a subtracting circuit.

Title: Developer concentration detector
Inventor: KUBOTA YOICHI
IPC: G03G15/08
Filed: 1987-12-04
Abstract: PURPOSE:To precisely detect the concentration of developer by using a LED as a light emitting source, executing sample and hold at the prescribed timing, and renewing and storing a reference voltage. CONSTITUTION:Light from the LED 31 strikes the developer D through a detecting window 34 which is composed of a crystal liquid plate and is driven by a crystal liquid driver 50. Therefore, reflected light is received by a photodetector 32. A changeover switch 44 switches the sample mode and hold mode of a sample and hold circuit 41. A differential amplifier 42 stores an electric signal as a standard when detecting a detecting pattern of crystal liquid in the detecting window 34. It inverts and amplifies a difference of voltage generated by a photodetector 32 at the time of detecting the developer, at which the detecting window 34 becomes transparent. Thus, a stable output which is always suited to situation condition is obtained without being affected by the fluctuation of the characteristics of light quantity of the LED caused by changes in the elapse of time and environment, and the concentration of developer is detected precisely.
