摘要： A horizontal deflection circuit for a multiple scan display, capable of controlling the horizontal deflection voltage for a plurality of horizontal scanning frequencies. The output power of the amplifier is controlled on the basis of the result of detection of the data of horizontal size of the image plane so that the horizontal size of the image plane is adjusted to a predetermined size. The data of horizontal size of the image plane is obtained through the detection of the amplitude of a flyback pulse signal. The amplitude of a sawtooth signal for horizontal scanning is controlled according to the deviation of the detected amplitude of the flyback pulse signal from a predetermined value. The horizontal deflection circuit is very simple in construction and is capable of carrying out continuous horizontal deflection according to the horizontal scanning frequency varying in a plurality of levels.

摘要： A desired number of cables are drawn, along with the falling charge, into a blast furnace from its top and the forward ends of the cables are melted upon reaching the melting zone in the furnace. The length of each of the cables to its melted end is measured in accordance with the result of a voltage pulse response measurement utilizing the distributed constant circuit characteristics of the cable, and the height level of the melting zone inside the furnace is measured from the cable length by correcting it for the amount of deflection of the cable within the furnace. By measuring the cable length at each of a plurality of radial locations of the furnace, it is possible to estimate the three-dimensional shape of the upper boundary of the melting zone with a high degree of accuracy.

摘要： There is disclosed a molten metal level monitoring and controlling apparatus for continuous casting machines which employs an eddy-current type distance measuring device for measuring the level of the molten metal in the mold of a continuous casting machine. The eddy-current type distance measuring device generates a molten metal level signal by detecting in a noncontact manner the distance between its detecting mechanism fixedly mounted in place just above the surface of the molten metal and the molten metal level. According to another embodiment of the invention, the detecting mechanism of the eddy-current type distance measuring device is arranged so as to be vertically movable just above the surface of the molten metal, whereby the detecting mechanism is moved in response to variations in the level of the molten metal to always maintain constant the distance of the detecting mechanism from the molten metal level, and the potentiometer attached to the detecting mechanism generates a molten metal level signal indicative of the distance travelled by the detecting mechanism. The thusly generated molten metal level signal is displayed on a recorder and it is also used for adjusting the pouring rate and the casting withdrawing rate through a monitoring and controlling mechanism so as to maintain the level of the molten metal in the mold within a predetermined range.
摘要翻译：公开了一种用于连续铸造机的熔融金属液位监视和控制装置，其使用涡流式距离测量装置来测量连铸机的模具中的熔融金属的水平。涡电流型距离测量装置通过以非接触的方式检测其固定地安装在熔融金属表面上方的位置的检测机构与熔融金属水平之间的距离来产生熔融金属液位信号。根据本发明的另一个实施例，涡流式距离测量装置的检测机构布置成可以在熔融金属的表面正上方垂直移动，由此检测机构响应于水平的变化而移动的熔融金属总是保持检测机构距离熔融金属水平的距离恒定，并且附接到检测机构的电位计产生指示由检测机构行进的距离的熔融金属水平信号。这样产生的熔融金属水平信号显示在记录器上，并且还用于通过监视和控制机构来调节浇注速度和浇铸速度，以便将模具中的熔融金属的水平保持在预定范围内。
