    • In a snow-removing machine, an expandable and contractible regulating mechanism is coupled between a steering handlebar of a machine body including a snow-removing section and a drive section capable of being turned relative to the machine body about a wheel driving shaft, and is capable of regulating the level of the snow-removing section relative to the drive section. The expandable and contractible regulating mechanism is comprised of a cylinder connected to the machine body, a piston which divides the inside of the cylinder into a first chamber and a second chamber, a piston rod coupled to the piston and connected to the drive section, a communication passage permitting communication between the first and second chambers, and an on-off valve for opening and closing the communication passage. A high-pressure gas is filled in the first and second chambers, so that the expansion and compression of the high-pressure gas is permitted upon closing of the on-off valve. Thus, during a snow-removing operation of the snow-removing machine, vibration applied to the drive section can be absorbed utilizing the expandable and contractible regulating mechanism for regulating the level of the snow-removing section.
    • 在除雪机中,可膨胀和收缩的调节机构联接在包括除雪部分的机体的转向车把与能够围绕车轮驱动轴相对于机体转动的驱动部分之间,并且是 能够调节除雪部相对于驱动部的高度。 可膨胀和可收缩的调节机构包括连接到机体的气缸,将气缸内部分成第一室和第二室的活塞,联接到活塞并连接到驱动部的活塞杆, 连通通道,允许第一和第二室之间的连通,以及用于打开和关闭连通通道的开关阀。 高压气体被填充在第一和第二室中,使得在关闭开关阀时允许高压气体的膨胀和压缩。 因此,在除雪机的除雪作业中,利用用于调节除雪部的水平的可膨胀收缩调节机构,能够吸收施加于驱动部的振动。

    • An apparatus for monitoring a water quality by raising an aquatic living thing in a monitoring water tank 1. The monitoring water tank 1 is taken through a camera 12 to be displayed on a television 14. A monitoring area E comprising a plurality of sensor points is set on a television scene through a light pen, and a fish sensing device 13 senses variation of the sensor points in luminance level to continuously detect the moving positions of fish F, F' under observation. A personal computer 15 detects, on the basis of the moving positions of the fish under observation, whether or not each of the fish under observation takes any one of a plurality of abnormal action patterns, and conducts an alarm operation if both the two fish F, F' under observation assume any abnormal action pattern.

    • A water quality monitoring apparatus including a raw water supply and discharge unit 7 equipped with a monitoring water tank 5 for breeding fish under observation. The raw water supply and discharge unit 7 is detachably placed in a lower section of a rack 1, and a video camera 8 is provided in opposed relation to the monitoring water tank 5. Also included are a fish detecting sensor 10 for detecting an actional pattern or the like of the fish under observation on the basis of a picture from the video camera 8 and a computer 11 for detecting the abnormality of the water quality on the basis of the detection result of the fish actional pattern or the like. The raw water supply and discharge unit 7 is made to be drawn from the rack 1 lower section, for example, at the time of cleaning its tanks. Thus, the maintenance thereof becomes easily possible, besides the entire apparatus becomes reducible in dimension to make the space necessary for the installation smaller.
    • 一种水质监测装置,包括:原料供水单元7,其配备有用于养殖观察鱼的监测水箱5。 原水供给和排出单元7可拆卸地放置在架子1的下部,并且摄像机8设置成与监视水箱5相对。还包括用于检测动作模式的鱼检测传感器10 基于来自摄像机8的图像观察的鱼等,以及基于鱼类动作模式等的检测结果来检测水质异常的计算机11。 原水供给排出单元7例如在清洗其箱体时从架子1的下部被拉出。 因此,除了整个装置的尺寸变小,使得安装所需的空间更小之外,其维护变得容易。
