    摘要： A carrier recovery circuit, adapted to a demodulation circuit according to a quasi-coherent detection method for generating baseband signals by way of quadrature detection on a received signal having an intermediate frequency, rotates phases of baseband signals; detects a phase error and an amplitude error; controls a bandwidth of a loop filter based on its difference, eliminates a high-frequency component from the phase error; and performs phase rotation based on the phase error eliminating its high-frequency component. It expands the bandwidth of the loop filter when a difference between the phase error and the amplitude error is greater than a predetermined threshold, whilst reducing bandwidth of the loop filter upon determining that the amplitude error decreases due to a reduction of the bandwidth of the loop filter. This optimizes the bandwidth of the loop filter to follow variations of the C/N ratio of the received signal, improving bit error rate.

    摘要： An automatic chemical analyzer suitable for chemically analyzing a number of analysis items is disclosed. Samples in sample containers are sequentially dispensed to an array of reaction vessels using a first pipetting tube. Reagent solutions selected in accordance with the analysis items are fed to the reaction vessels using a second conductive pipetting tube. The reaction solutions in the reaction vessels are measured by a photometer. When the reagent solutions are sucked into the second pipetting tube, the liquid levels of the reagent solutions in the reagent containers are detected by a liquid level sensor formed by the second pipetting tube and a conductive electrode. The amounts of the reagent solutions remaining in the reagent containers are determined based on the position of the liquid level sensor and the numbers of times of dispense allowed to the reagent solutions with respect to the analysis items are displayed on a cathode ray tube.

    摘要： An electric wire in a rising part, which is obtained by covering a conductor whose sectional shape is a square with an insulating film, is formed in a curve so that the inside of the curve is along the circumference of a circle having a radius “r” until the electric wire risen from the coil in which the electric wire is wound is turned in a desired direction. The radius “r” of the circle has a length, which is equal to or larger than ½ of one side R of the square as the sectional shape of the conductor of the electric wire.
