摘要： Image signals of moving subjects which are imaged by a slit camera, and time information generated by a time information generator after it has been reset by a start trigger signal, are successively stored in and erased from a large-storage-capacity memory on a first-in, first-out basis. After elapse of a predetermined time period after a record trigger signal has been supplied from a record trigger generator, a storage time control circuit controls the memory to stop storing and erasing the image signals and the time information, and keeps the image signals and the time information stored which have been stored before the memory stops storing and erasing the image signals and the time information. The image information of the subjects and the time information associated with the image information can be stored in the memory within a storage time that depends on the storage capacity of the memory.

摘要： In a camera section, a luminance signal and the predetermined hue gate signal are modulated by a modulator in a quadrature modulation manner and the modulated signal is transmitted to a camera control unit via a cable. The modulated signal is separated by a branching filter in the unit and demodulated by a demodulator to generate the luminance signal and the detection signal. A signal to which the luminance signal and the detection signal are added, is used as a monitor video signal and a white image is displayed on a monitor screen within a range for the detection signal. Thus, the range detection signal can be observed with the monitor screen. Since the unit uses the added signal as the monitor video signal and the luminance signal for another purpose, the range of the detection signal can be observed by the monitor screen while using the luminance signal for another purpose.

摘要： The present invention relates to a method which may decarburize high Cr molten metal for a short period of time under an atmospheric pressure, while checking loss of Cr by its oxidation. A basic feature of the invention is to blow from the furnace top lance a decarburizing O.sub.2 diluted by an inert gas into the high Cr molten metal supported in a container as well as blow the inert gas from bottom tuyeres so as to forcibly agitate the molten metal. Another feature of the invention is to control a slag amount during the above decarburizing blowing so as to check the Cr oxidation loss. A further object of the invention is to carry out a denitrification in the above decarburization, thereby to produce low N molten metal while checking the loss by Cr oxidation.
