Patent JP-H04117005-A (JP)
Title: Bias circuit
Inventor: HIRAYAMA MASAHIKO
IPC: H04B10/40
Filed: 1990-08-31
Abstract: PURPOSE:To ensure a high gain without connecting a bias circuit to a feedback line of a noninverting amplifier so as to select a 1st resistance freely. CONSTITUTION:A diode D1, a cathode terminal, a resistor R1 and a photosensing element D2 are connected to an input terminal 2 and an anode of the diode D1 is connected to a collector of a PNP transistor(TR) Q2 whose emitter connects to a constant current source I2. Moreover, the base of the PNP TR Q2 is connected to the other terminal of the resistor R1 and a reference voltage source V1 to form the bias circuit at the input terminal of a noninverting amplifier. Thus, the photosensing element current at a high input is fed from the constant current source I2 via the PNP TR Q2 and the diode D1 and the base current of the PNP TR Q2 flows to the reference voltage source, then no current flows to a resistor R3. Thus, the resistance of the resistor R3 is selected freely and the gain of the noninverting feedback amplifier is increased by selecting the resistance of the resistor R3 to be larger.

Abstract: PURPOSE:To accurately and rapidly measure the concn. of an aqueous chemical agent solution by measuring the near infrared absorption spectrum in the specific wavelength band of the aqueous chemical agent solution for a semiconductor process whose concn. is known to prepare a calibration formula. CONSTITUTION:The near infrared absorption spectrum of an aqueous chemical agent solution for semiconductor process is compared with that of pure water and a wavelength lambdai giving an absorption band having marked significant difference between both of them in a wavelength band of 800 - 1,400 nm is selected. The absorption spectrum of a standard sample whose concn. is known in the wavelength band of 800 - 1,400 nm is measured to calculate absorbancy Ai in the wavelength lambdai and the relation between concn. C and the absorbancy Ai is analyzed to prepare a calibration formula : C=SIGMAalphaiAi (wherein a constant alphai is determined by the kind of a chemical agent, the wavelength li and the number of selections of the wavelength lambda). The absorption spectrum of an aqueous sample solution whose concn. is known in the wavelength band of 800 - 1,400 nm is measured to calculate absorbancy in the wavelength li and, when this absorbancy is substituted for the calibration formula, the concn. of the sample solution can be rapidly and accurately calculated.
