Title: Photodetection circuit
Inventor: SOYA TAKASHI
IPC: H03K5/08
Filed: 1993-10-26
Abstract: PURPOSE:To obtain a photodetection circuit which does not perform a malfunction for noise. CONSTITUTION:A capacitor 101 is connected with the cathode of a photodiode 301 and the input side of a current mirror circuit composed of transistors 102, 103 and 105 and a resistance 104. The area of the emitter of the transistor 105 is 10 times as large as the emitter of the transistor 102. The collector of the transistor 105 is connected with the anode side of the photodiode 301. When the Junction capacity of the photodiode 301 is C301, the capacity of the capacitor 101 is C101 and the voltage change of noise is dVcc/dt, the current due to noise to be inputted in the transistor 303 becomes (C301.dVcc/dt)-(C101.dVcc/dt)X10. When (C301/C101)=10 is made, this current becomes 0 and the current due to noise does not flow. Thus, the inverted input and noninverted input of a comparator 318 becomes the same phase and the circuit does not perform a malfunction.

Title: Method for stabilizing wavelength of laser spectroscope system
Inventor: MCANDREW JAMES
IPC: G01J3/10
Filed: 1996-10-08
Abstract: PROBLEM TO BE SOLVED: To provide a method for stabilizing the wavelength of a laser spectroscope that is useful for spectrophotometry. SOLUTION: Initial scanning is made by supplying a current signal or a voltage signal to a laser. The current signal value or the voltage signal value are increased with a constant increment over the total number of signal values determined in advance from a minimum signal value to a maximum signal value. The minimum signal value and the maximum signal value are selected so that absorption characteristics of a seed to be measured enter a scanning range whose boundary is determined by them (a). The relative position of absorption characteristics for the supply signal value of the previous scanning is measured by analyzing the output of a detector corresponding to the signal value of previous scanning (b). An absorption value corresponding to the absorption characteristics is measured (c). The concentration of the seed to be measured is calculated (d).  A signal value is set again from the previous scanning and a new signal scanning is defined and a relative position for the supply signal value of the absorption characteristics of a new signal scanning is set to the same value as in the last scanning (e). Scanning is made (f). Processes (b)-(f) are repeated until spectrometry is completed (g).
