摘要： An image capturing device having a function of clamping an image signal. When the image capturing device is activated, a synchronous signal generating section begins creation of a horizontal synchronous signal, and a counter begins counting a pulse of the horizontal synchronous signal. When the counted value reaches a predetermined value, the clamping capability control section changes the level of a clamp mode signal to an H level. During a period from the start of power supply to the image capturing device to the raising of the level of a clamp mode signal to an H level, a clamp pulse generating section sets a longer width for a clamp pulse than in a normal operation so that a switch element of a clamping circuit remains in an on state in a longer period, whereby a smaller time constant for clamping is set. After elapse of a predetermined period, the switch element is controlled so as to remain in an ON state in a normal period, which is relatively short, whereby a larger time constant for clamping is set. With this arrangement, noise which would be caused with a small clamping time constant is suppressed.

摘要翻译： 具有夹持图像信号的功能的图像捕获装置。 当图像拍摄装置被激活时，同步信号产生部分开始创建水平同步信号，并且计数器开始计数水平同步信号的脉冲。 当计数值达到预定值时，钳位能力控制部分将钳位模式信号的电平改变为H电平。 在从供电开始到图像捕获装置到将钳位模式信号的电平提高到H电平的期间中，钳位脉冲发生部分将钳位脉冲的宽度设置为比正常操作更长的宽度，使得 钳位电路的开关元件在较长时间内保持导通状态，由此设定较小的钳位时间常数。 在经过预定时间后，开关元件被控制成在相对较短的正常时段内保持在ON状态，由此设定较大的夹紧时间常数。 通过这种布置，可以抑制以小的夹紧时间常数引起的噪声。

摘要： The present invention provides a process for producing lower alkyl fatty esters from fatty acids and lower alcohols, wherein lower alkyl fatty esters are produced in higher yield with a reduction in the amount of the remaining fatty acids. The process of the present invention comprises bringing fatty acids into contact with gaseous lower alcohols in fixed bed(s) charged with a weakly acidic solid catalyst by countercurrent operation, by co-current operation and subsequent countercurrent operation or by pseudo-countercurrent operation, thus feeding and reacting the fatty acids and lower alcohols in fixed-bed reactor(s) charged with a weakly acidic solid catalyst to produce lower alkyl fatty esters.
