摘要： A gas concentration measurement device which utilizes a TDLAS measurement method, and in which the phase-sensitive detection can be performed by digital processing using an integer-arithmetic device, is provided. In the gas concentration measurement device according to the present invention, AC components corresponding to integer multiples of a modulation frequency f contained in an input signal are removed by taking a moving average of data obtained from an output signal of a multiplier 62 for a period of time corresponding to one cycle of the modulation frequency f. As a result, a DC component in the output signal of a digital filter 63 relatively increases, making it easier to extract the DC component by a digital low-pass filter 64, so that a sufficiently accurate phase-sensitive detection can be made even if a digital processing based on integer arithmetic is used.

摘要： A distribution of AC electric field regularly arranged in a cell is formed while storing a sample having particles dispersed in a medium in the cell, whereby the particles are dielectrically migrated in the medium to generate a diffraction grating by density distribution of the particles. Diffracted light generated by irradiating the diffraction grating by density distribution with measuring light is detected, and evaluation of dielectrophoretic intensities of the particles and/or the medium is performed from the detection result. According to this method, evaluation of dielectrophoretic characteristics can be performed without adhering a phosphor to particles, and since even a particle small in size can achieve a detection level by collecting a number of such particles to form a diffraction grating, dielectric characteristics of microparticles of several nanometers in diameter can be thus quantitatively measured with high sensitivity.

摘要： A floating diffusion region is formed at an edge of a light-receiving surface of an embedded photodiode, with a transfer gate electrode located therebetween. A first region, with radially extending portions centered on the FD region, and a second region, located to the outside of the first region, are created in the substantially sector-shaped light-receiving surface. A dopant whose conductivity type is the same as the signal charges to be collected in the first region are introduced, whereby an electric field for moving the signal charges from the radially extending sections towards the center is created due to a three-dimensional field effect. As a result, the charge-transfer time is reduced. Additionally, since a circuit element in the subsequent stage can be placed adjacent to the floating diffusion region, the parasitic capacitance of the floating diffusion region can be reduced and a highly sensitive element can be obtained.

摘要： A transistor (24) which acts as a load-current source for a source follower amplifying transistor (22) for outputting a pixel signal to a pixel output line (40) is provided in each picture element (10), whereby a high bias current is prevented from passing through the high-resistance pixel output line (40), so that a variation in an offset voltage among picture elements is suppressed. Inclusion of the high-resistance pixel output line (40) into the source follower amplification circuit is also avoided, whereby the gain characteristics are prevented from deterioration. Thus, the S/N ratio of the picture element is improved so as to enhance the quality of the images.
