摘要： PROBLEM TO BE SOLVED: To obtain an oscillation circuit which significantly reduces oscillation rise time and obtains an oscillation output just after start of oscillation. SOLUTION: A short-circuiting means 7 is placed in parallel as an input terminal voltage biasing means of an inverting amplifier 1 between its input and output terminals, and an output buffer circuit, which receives an output of the inverting amplifier 1 and performs oscillation output, always amplifies a minute-amplitude output of the inverting amplifier 1. At the time of start of oscillation, the inverting amplifier 1 is activated, a vibrator 5 is excited by applying potential difference to both ends of the vibrator 5, and thereafter the short-circuiting means 7 is operated in a predetermined period to establish a short circuit between the input and output terminals of the inverting amplifier 1. Thus, resonance-current peak in the vibrator 5 is increased and minute vibrations of the vibrator 5 are enhanced, and therefore the start of oscillation at an early stage can be achieved.

摘要翻译：要解决的问题：获得显着减少振荡上升时间的振荡电路，并获得刚刚开始振荡之后的振荡输出。解决方案：短路装置7作为反相放大器1的输入端电压偏置装置并入其输入和输出端之间，输出缓冲电路接收反相放大器1的输出和执行振荡输出，总是放大反相放大器1的微振幅输出。在振荡开始时，反相放大器1被激活，通过向振子5的两端施加电位差来激励振子5，以及此后，短路装置7在预定周期内操作，以在反相放大器1的输入和输出端之间建立短路。因此，振动器5中的谐振电流峰值增加，振动器5的微小振动增强，因此可以在早期阶段开始振荡。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To detect foreign matte in a liquid filled in a transparent container. SOLUTION: After the transparent container is rotated on a transfer line, it is halted, and transferred on the transfer line as it is. While cameras are made to follow the container, photographing is performed a plurality of times. Foreign matter during rotation is detected by obtaining the difference between the two photographed images. In this case, the contour of the container remains in difference images to be incorrectly judged as foreign matter or interferes with foreign matter detection. Then the contour of one image among the two photographed images is enhanced, and the difference images are subjected to a mask processing with binarized images.
