Title: Photometric apparatus
Inventor: HOSOI YOICHI
IPC: G01J1/42
Filed: 1990-08-13
Abstract: PURPOSE:To automatically correct the change of the sensitivity of a photomultiplier due to the temperature change of the using circumstances and with time thereby to output a correct measuring value by providing a correcting means for correcting an output of the photomultiplier based on an output of a photodetector. CONSTITUTION:The central wavelength of the light generated from each of two or more kinds of light sources LEDX2 6, LEDY 7, LEDZ 8 is different. A photomultiplier 1 receives the light of these two or more kinds of the LEDs 6-8. A photodetector, namely, a silicon photodiode 4 detects a reference light of the LEDs 6-8, having superior temperature characteristics to the photomultiplier 1. Therefore, the reference light becomes a reference for correction of the temperature characteristics of the photomulti plier 1. A processor 13 corrects the output of the photomultiplier 1 on the basis of the output of the photodetector 4. It is more preferable that the light of the two or more kinds of LEDs 6-8 is selectively guided to the photomultiplier 1 through an optical fiber 12. The output of the photomultiplier 1 is corrected with the utilization of the favorable characteristics of the silicon photodiode 4, thereby to improve the temperature characteristics of the photomultiplier 1. Accordingly, a correct measuring value is obtained.

Title: Electric charge detection circuit
Inventor: ISHIHARA HIROSHI
IPC: G01R19/00
Filed: 1995-08-21
Abstract: PROBLEM TO BE SOLVED: To obtain a highly sensitive electric charge detection circuit which is not effected by an output capacitance and a wiring capacitance of a switching element by using capacitances, the switching element, differential amplifiers and resistances in a specified configuration. SOLUTION: A signal electric charge is stored into a capacitance C1 while a switching element S1 is OFF. This electric charge Q flows to an electric charge detection circuit by turning ON the switching element S1 and a voltage of Vout2=(Q/C3)×(R1/R2) is generated at an output terminal of a differential amplifier 2. That is the voltage of Vout2 is proportional to the electric charge Q. The value of the resistance R1 is preferably larger than that of the resistance R2, hence allowing raising of the sensitivity of a circuit output. The electric charge Q is inputted into a current-voltage conversion circuit constituted of the differential amplifier 2, a capacitance C3 and a resistance R3 through a current-voltage conversion circuit constituted of a differential amplifier 1, the capacitances C1 and C2 and the resistances R1 and R2.  Thereby effect of a wire capacitance C4 can be eliminated.
