    • Disclosed is a laser apparatus for effecting laser oscillation by exciting a laser medium by discharge between an anode and a cathode opposedly arranged to each other in a discharge tube, comprising means disposed in the discharge tube to support both the electrodes movably along the axial direction of the discharge tube so as to prevent warp of the electrodes on laser oscillation and keep the parallelism therebetween with high accuracy. Also disclosed is a laser apparatus comprising main discharge means for effecting laser oscillation by exciting a laser medium by generating discharge, and preionization means for generating ionization previously to the discharge by the main discharge means so as to stabilize laser oscillation under a high gas pressure and a high current density.

    • A monitoring apparatus is provided which can ensure the prevention of a paper break even in a poor installation environment. A light source (9) illuminates light (9a) on a lateral edge (1a) of wet paper (1) and a camera (5) captures light (9b) reflected therefrom. The camera (5) is a micro camera and completely covered by a camera box (10). The camera box (10) has an observation window (10a) which is made of a transparent member, at the lens side (5a) of the camera (5). The outer surface of the observation window (10a) is coated and an air curtain (12a) that flows from above to below prevents staining caused by mist. The air curtain (12a) is formed in such a manner that air that is continuously supplied inside a cover (11) flows along the outer surface of the observation window (10a) from an opening portion (11a). A color image obtained by the camera (5) is subjected to image processing in an image processing device (6) and the resulting image is projected on a monitor TV (7), so that variations of the release point (3) can be monitored. This allows for forecasting of a machine abnormality leading to a paper break.
    • 提供了一种即使在安装环境差的情况下也能够防止纸张断裂的监视装置。 光源(9)照亮湿纸(1)的侧边缘(1a)上的光(9a),并且照相机(5)捕获从其反射的光(9b)。 相机(5)是微型相机,并被相机盒(10)完全覆盖。 相机盒(10)在照相机(5)的透镜侧(5a)处具有由透明构件制成的观察窗(10a)。 观察窗(10a)的外表面被涂覆,并且从上方向下流动的气帘(12a)防止由雾引起的污染。 空气幕(12a)形成为使得在盖(11)内连续供给的空气沿着观察窗(10a)的外表面从开口部(11a)流动。 通过照相机(5)获得的彩色图像在图像处理装置(6)中进行图像处理,并将所得到的图像投影到监视器TV(7)上,从而可以监视释放点(3)的变化 。 这样可以预测导致断纸的机器异常。
