摘要： The difference in brightness between the brightest area and the darkest area of the object of distance measurement can be speedily detected, as described above, and it can be determined before contrast calculation and correlation calculation are performed whether or not reliable distance measurement is possible. Therefore, where the object of distance measurement suffers from inadequate contrast, unnecessary performance of contrast calculation and comparative calculation regarding the distributions of accumulated charge can be avoided, so that the user can be promptly informed of the inadequacy in contrast and appropriate measures, such as emission of auxiliary light for distance measurement, can be speedily taken.

摘要： The degree of a structure change of the sugar chain of a glycoprotein caused by a disease can be measured with high precision rapidly by separating and measuring two or more forms of glycoproteins which are different in sugar chain structure but have substantially the same protein structure, by using a combination of a lectin capable of recognizing the specific sugar chain structure of at least one of these glycoprotein analytes to be measured, and a first antibody which has a property of binding to all the glycoprotein analytes but is kept from binding to glycoprotein analyte(s) having the lectin attached thereto; and separating and measuring glycoprotein analyte(s) having the first antibody attached thereto and glycoprotein analyte(s) having no first antibody attached thereto, by utilizing differences in properties between the former glycoprotein analyte(s) and the latter glycoprotein analyte(s).

摘要： In a preferred embodiment, a lighting device may include a metal halide lamp and a polarity inversion step-up circuit which generates a DC voltage Va of minus value. An inverter circuit inverts the output of the polarity inversion step-up circuit to create AC voltage and supplies it to a discharge lamp. Consequently, the discharge lamp has applied a square wave AC voltage with voltage between zero and peak being nearly .vertline.Va.vertline.. Potential of a lighting tool to enclose the discharge lamp is set to ground potential. Since the discharge lamp is lit always at a mean lighting potential which is less than the potential of the lighting tool, the Na loss phenomenon is suppressed. That is, life of the discharge lamp can be lengthened. Other embodiments also operate to keep the mean lighting potential of the discharge lamp less than the potential of the lighting tool.

摘要： In an optical communication system, a transmitted signal is modulated with a subcarrier signal having a frequency higher than the frequency of said transmitted signal on the transmission side, the modulated signal light emitted to a transmission channel. On the reception side, the received signal is filtered and decoded by means of a band-pass filter having a center frequency approximately equal to the frequency of the subcarrier signal of the received signal. The above arrangement makes it possible to achieve an arrangement free from the influence of deterioration in the degree of modulation due to spontaneous emission generated from an optical amplifier disposed midway along the transmission channel. The optical amplifier may be an optical differential gain amplifier which has the differential-gain optical input/output characteristics of outputting spontaneous emission of low intensity according to a digital signal value "0" and output light of high intensity according to a digital signal value "1". The arrangement enables optical amplification of signal light without the risk of outputting high-level spontaneous emission due to direct current excitation. It is therefore possible to provide received signals of high quality by eliminating any deterioration in S/N ratio and any deterioration of the degree of modulation of signal light due to spontaneous emission from the optical amplifier disposed midway along the transmission channel.
