摘要： An FPD, being offline from an X-ray source, detects X-ray irradiation from the X-ray source to detect an X-ray image. The FPD includes pixels arranged in two dimensions, scan lines corresponding to respective rows of the pixels, signal lines corresponding to respective columns of the pixels, and switching elements provided to the respective pixels to allow performing accumulation operation or readout operation. At least one of the pixels is used as a detection pixel to detect a start of the X-ray irradiation. First and second voltage signals are obtained successively through the signal line to which the detection pixel is connected. The start of the X-ray irradiation is judged based on a difference between the first and second voltage signals.

摘要： A flat panel detector has an imaging area, in which pixels are arrayed in a matrix and signal lines for reading out electric signals from the pixels are provided, to detect an image of a subject from x-rays which are incident on the imaging area after penetrating the subject. Detective elements are arranged in the imaging area, to output electric signals corresponding to incident x-rays. Based on previously stored sensitivity data on the detective elements, high-sensitivity elements are selected from among the detective elements. The start of radiation and the end of radiation of x-rays toward the imaging area are detected by monitoring the electric signals from the selected high-sensitivity elements, to control operation of the imaging device on the basis of the detected start and end of radiation.

摘要： A flat speaker includes a casing with a display window, a vibratory sound panel mounted to the display window and having a display region and an exciter mount region, a display screen disposed internally of the display region, and an exciter mounted to the inner surface of the exciter mount region. A dust barrier is disposed to isolate a first space defined between the display region and the display screen from a second space surrounding the first space. The dust barrier has a dust barrier member disposed between the display region and the exciter mount region and extending across the vibratory sound panel to inhibit dust particles from moving from said exciter mount region to said display region within said casing. The dust barrier member is yieldingly deformable in response to vibration of said vibratory sound panel.

摘要： An x-ray image detector monitors the intensity of incident x-rays to detect an end of radiation from an x-ray source when the x-ray intensity decreases to a threshold level or less. The x-ray intensity gets down to zero with a variable time lag from the start of decreasing, called radiation wave tail. Depending on the gradient of declivity in time curve of the decreasing x-ray intensity, calculated at the time when the end of radiation is detected, the x-ray image detector decides a delay time from the end-of-radiation detection time to a reading start time to start reading signal charges from the image detector. Thus, the reading start time may be adjusted to the point when the x-ray intensity gets down to zero, which will improve S/N ratio and prevent shading artifacts.
摘要翻译： 当X射线强度降低到阈值水平或更低时，X射线图像检测器监测入射的X射线的强度以检测来自X射线源的辐射的结束。 X射线强度从减小开始的可变时间滞后变为零，称为辐射波尾。 根据在检测到辐射结束时计算出的x射线强度减小的时间曲线下的倾斜度的梯度，X射线图像检测器决定从放射检测结束时间到延迟时间的延迟时间 读取开始时间开始从图像检测器读取信号电荷。 因此，可以将读取开始时间调整为当x射线强度降至零时的点，这将提高S / N比并防止遮蔽伪像。

摘要： An FPD has plural pixels arranged in two dimensions. The pixels include a short pixel directly connected to a signal line, and a comparative pixel connected to another signal line through a TFT. In irradiation detecting operation, a control section monitors a voltage signal from the short pixel. When the voltage signal is a predetermined threshold value or more, the control section detects the start of X-ray irradiation, and provisionally starts charge accumulation operation. Then, the control section calculates the difference in the voltage signal between the short pixel and the comparative pixel. When this difference is another threshold value or more, the detection of the start of X-ray irradiation is judged to be valid. When the difference is less than the threshold value, the detection is judged to be misdetection caused by shock noise. The charge accumulation operation is aborted, and the irradiation detecting operation is restarted.
