摘要:
An automatic photometric analyzer is disclosed using an automatic exchanger holding a sample solution. A recorder, a photometer, an injector for the sample solution, and supply systems for pure water and coloring solutions are used. Additionally, valves under control of an automatic controller properly control the flow and the solution to provide a simple and practical apparatus with rapid automatic operation for analysis. The injector delivers reactant solutions to a reactor from which reactant is circulated through the photometric means to measure the absorbency thereof and back to the reactor.

There is disclosed a photoelectric conversion method, a light receiving circuit, and an optical communication system, in which even if an average received light level varies, a constant output level of demodulated signal can always be obtained. In the photoelectric conversion method, the light receiving circuit and the optical communication system of the present invention, a light signal is received by a light receiving diode and converted to an electric signal. An alternating component is removed and a direct current component is taken out by a low-pass filter to detect an average received light level of the light, a difference of the average received light level and a preset reference voltage is amplified by a differential amplifier to output a control voltage of a variable gain amplifier, and the electric signal is amplified with a gain corresponding to the control voltage by the variable gain amplifier to obtain a demodulated signal.

Radio communication systems, e.g. cellular telephones, have employed a space diversity antenna system which includes a plurality of antennas. In the space diversity antenna system for use in the cellular telephone, since two antennas are positioned adjoining each other, the space diversity effect cannot be adequately provided. To solve this problem, the polarization diversity antenna system according to this invention incorporates a first antenna, a second antenna, and a conductive board on which the second antenna is fixed at a given position, thus preventing the current flowing in the conductive board from causing the reception characteristic of the second antenna to deteriorate.
