Water-absorbent agent and method for manufacturing the same

A hydrogel polymer obtained by polymerizing a monomer component including acrylic acid (salt) is post-neutralized so that each of polymer particles derived from a polymer produced by neutralizing the hydrogel polymer has an allowable neutralization ratio. The polymer as obtained by neutralizing the hydrogel polymer is reacted with a crosslinking agent reactive to a functional group of the polymer. The allowable neutralization ratio, for example, is a neutralization ratio which is not lower, by not less than 20 mole percent, or more than, at least 55 mole percent, than an average neutralization ratio of a mass of the polymer particles, and the post-neutralization is carried out so that a number of polymer particles having a non-allowable neutralization ratio outside the allowable neutralization range is not more than 10 in 200 polymer particles, thus obtaining a water-absorbent agent having high absorbency under no applied pressure and high pressure wherein the amount of water soluble component is lower compared with the conventional water-absorbent agent and a change in pH of a swollen gel is small.

Hologram optical element, method of fabrication thereof, and image display apparatus

As a result of the light from a plurality of point light sources located at an identical position being refracted at a surface of a color correction prism at the time of exposure, the chromatic aberration occurring as a result of the light (for example, image light) directed via a refractive surface of the optical system used at the time of reconstruction to the viewer's pupil being refracted at this refractive surface is corrected for. Moreover, at least two of another set of a plurality of point light sources are arranged at such positions as to provide angles of incidence commensurate with the deviation between them of the ratio between exposure wavelength and use wavelength. Thus, even in a case where the ratio between exposure wavelength and use wavelength differs between at least two colors, it is possible to make equal for all colors the angle of diffraction that provides the maximum diffraction efficiency at the hologram optical element at the time of reconstruction, and thereby to correct for color shifting depending on the viewing angle.

An object of this invention is to implement a radiographic apparatus which can stably obtain a moving image at a high speed by suppressing a voltage variation in GND or power supply line and omitting the standby period for each frame. To achieve this object, during a period after electrical signals from conversion elements (S1-1–S1-3) in one control interconnection (G1) are transferred and read for each row by a driving circuit section (SR1) before electrical signals in the next control interconnection are transferred and read, the read-accessed conversion elements are refreshed for each row, thereby eliminating the necessity for preparing a refresh period in acquiring continuous moving images. In addition, since the conversion elements are refreshed for each row, the dark current (transient current) in the refresh mode can be made small as compared to a case wherein all the conversion elements are refreshed at once. With this arrangement, the voltage variation in GND or power supply line is suppressed.
