    摘要： An X-ray radiograph apparatus comprising an X-ray source which irradiates a subject body with X rays of a low level radiation dose during the fluoroscopic operation and irradiates the same with X rays of a high level radiation dose during the radiographic operation; an X-ray image intensifier for converting an X-ray image, which has irradiated by the X-ray source and has penetrated through the subject body, into an optical image; a distributor for distributing an output optical image from the X-ray intensifier to a plurality of optical paths; a fluoroscopic imaging element arranged on one of plural output optical paths of the distributor; a radiographic imaging element arranged on an output optical path of the distributor other than the output optical path on which the fluoroscopic imaging element is arranged, the radiographic imaging element having a higher resolution than the fluoroscopic imaging element and having a lower imaging speed than the fluoroscopic imaging element; and an image display for displaying a fluoroscopic image or a radiographic image formed based on output signals from the fluoroscopic imaging element or the radiographic imaging element, respectively. With this, it becomes possible to collect, at the same time, the high resolution static image (radiographic image) by the radiographic imaging element and the moving image (fluoroscopic image) by the fluoroscopic imaging element. It is also possible to improve the S/N ratio of the radiographic image. Furthermore, should the radiographic image element include a defect pixel, the influence thereby would be lowered to minimum or to zero.

    摘要： A driving power unit for a liquid crystal display element, which charges an electrostatic charge on the surface of the liquid crystal display element having at least a conductive layer and a liquid crystal-dispersed polymer layer in which a liquid crystal is finely dispersed into a polymer matrix, has a blocking oscillator circuit for boosting a low voltage generated by a low-voltage DC power source, a rectifier diode for rectifying the voltage boosted by the blocking oscillator circuit, a smoothing capacitor for being charged by application of the rectified voltage and smoothing an output voltage, and a resistance interconnected between the smoothing capacitor and an output terminal to control an output current value to 5 mA or less. A liquid crystal light-modulating device has a driving power unit and a liquid crystal light-modulating panel including a pair of electrodes at least one of which is transparent or translucent, and a liquid crystal-dispersed polymer layer sandwiched between the electrodes.
