Abstract: This invention relates to a photoconductive antenna element having a structure capable of preventing element characteristics from deteriorating and attain a smaller size at the same time. This photoconductive antenna element (17) comprises a pair of electrodes (21) formed on a semiconductor layer (19). Each electrode (21) is constituted by an antenna part (22), pad parts (23), and a line part (24) connecting them, while the line part (24) includes a parallel portion (24a) extending from the antenna part (22). In the line part (24) of one electrode (21), a portion other than the antenna region (A) is bent opposite to the other electrode (21). In the line part (24) of the other electrode (21), a portion other than the antenna region (A) is bent opposite to the one electrode (21). This structure can prevent the photoconductive antenna element (17) from deteriorating its element characteristics and make it smaller.

Abstract: The present invention relates to a manufacturing method of obtaining a photoelectric converting device which can sufficiently maintain airtightness of a housing space for photocathode without degradation of the characteristics of the photocathode. In accordance with the manufacturing method, on the side wall end face of a lower frame and a bonding portion of an upper frame forming an envelope of the photoelectric converting device, a multilayered metal film of chromium and nickel is formed. In a vacuum space decompressed to a predetermined degree of vacuum and having a temperature not more than the melting point of indium, these upper and lower frames introduced therein are brought into close contact with each other with a predetermined pressure while sandwiching indium wire members, and accordingly, an envelope having a housing space whose airtightness is sufficiently maintained is obtained.

Abstract: A fly-eye lens 30 formed by arranging a plurality of condensing lenses 32 in a matrix on a plane, a CMOS sensor 10 having a light receiving surface arranged in parallel to the fly-eye lens 30 at a distance corresponding to the focal length of the condensing lenses 32, and a phase calculation device 20 are provided. A center position calculating part 243 calculates the center positions of bright spots (focal points) of focal point images on the light receiving surface by comparison with luminances of adjacent pixels. A centroid data processing part 245 calculates the 0-order moment (total of bright spot luminances in the centroid operating region), first-order moment in the x direction, and first-order moment in the y direction of the luminance in a centroid operating region centered on the bright spot center position. A centroid position calculating part 261 calculates the centroid position of each bright spot based on these centroid data.

Abstract: A fluorescence probe dye is introduced into a cell, and excitation beams at three defferent wavelengths are irradiated to the cell to measure intensities of the fluorescence generated by the excitation beams, corresponding to the three wavelengths. Then, an equilibrium reaction equation for concentrations of the fluorescence probe dye, protein, free ions and their complexes in the cell, and a relationship equation between the fluorescence probe dye, protein, free ions and their complexes are used as simultaneous equations to give concentrations of the respective components. This process can correct interactions among various components of the cell due to bonding among them and a correct ion concentration can be determined.
