摘要： A bismuth-substituted rare-earth iron garnet crystal film (RIG) which has an insertion loss of less than 0.6 dB and which can be produced in a high yield, as well as an optical isolator, which is grown by liquid phase epitaxy on a non-magnetic garnet substrate represented by a chemical formula of Gd3(ScGa)5O12, wherein the RIG is represented by a chemical formula of Nd3-x-yGdxBiyFe5O12, and x and y satisfy 0.89≦x≦1.43 and 0.85≦y≦1.19. In contrast to conventional RIGs, the RIG represented by the chemical formula of Nd3-x-yGdxBiyFe5O12 of the present invention has an insertion loss of less than 0.6 dB and makes it possible to reduce the amount of heat generated because of absorption of light at wavelengths of about 1 μm. Hence, the RIG has such a remarkable effect that the RIG can be used as a Faraday rotator used for an optical isolator in a high-power laser device for processing.

摘要： A pre-amplifier (column region unit) of a solid-state imaging device including a pixel-signal controller. The pixel-signal controller, for each vertical signal line, detects the level of each pixel signal independently by a pixel-signal detector on the output side of a pixel-signal amplifier, and sets a gain independently to the pixel-signal amplifier according to the level of the signal. At a subsequent stage of the solid-state imaging device, an analog-to-digital (A/D) converter and a signal extending unit are provided. The A/D converter digitizes a pixel signal, and the digitized pixel signal is corrected by a gain set to the pixel-signal amplifier with reference to a classification signal from the pixel-signal detector, so that the dynamic range of signals of one screen is extended.

摘要： When pixel signals are separately read from a plurality of horizontal signal lines to achieve high-speed processing, color difference in image signals and stripes are eliminated.In the operation of reading the pixel signals from the (2n)th row, the pixel signals from R pixels on odd columns are output to an output system A through a horizontal signal line (60A). On the other hand, the pixel signals from Gr pixels on even columns are output to an output system B through a horizontal signal line (60B). In the operation of reading the pixel signals from the (2n+1)th row, the pixel signals from Gb pixels on the odd columns are output to the output system B through the horizontal signal line (60B) by the switching operation in a switching circuit (50). Similarly, the pixel signals from B pixels on the even columns are output to the output system A through the horizontal signal line (60A) by the switching operation in the switching circuit (50).

摘要： An image pickup apparatus comprising an array of unit cells, vertical signal lines, and a control circuit. The unit cells are arranged in rows and columns. Each unit cell has a light-receiving device for receiving light and generating an electric charge corresponding to the light, a charge-accumulating section for accumulating the electric charge generated by the light-receiving device, a transfer device for transferring the electric charge from the light-receiving device to the charge-accumulating section, and a charge-limiting device for limiting the electric charge accumulated in the charge-accumulating section. The vertical signal lines extend along the columns of unit cells, respectively, each for receiving a electric data item corresponding to the electric charge accumulated in the charge-accumulating section of any unit cell of the associated column. The control circuit controls each of the unit cells, causing the charge-limiting device to limit the charge generated by the light-receiving device during a first period and transferred to the charge-accumulating section through the transfer device. The charge generated by the light-receiving device during a second period following the first period and transferred to the charge-accumulating section through the transfer device is added to the electric charge accumulated in the charge-accumulating section.
