    摘要: A picture signal conversion device arranged to obtain an interpolation signal by using a scanning line signal of a first picture signal which has scanning line signals corresponding to a predetermined number of scanning lines within one field period and to convert the first picture signal into a second picture signal which has a greater number of scanning lines than that of the first picture signal comprises: first interpolation signal generating means which generates a first interpolation signal for the present field by using a scanning line signal obtained within the present field; second interpolation signal generating means which generates a second interpolation signal for the present field by using a scanning line signal of another field; output means arranged to detect the correlativity of scanning line signal between fields and to selectively produce, according to the detected correlativity, the first or second interpolation signal generated from the first or second interpolation signal generating means; and detection characteristic control means for controlling the correlativity detecting characteristic of the output means according to the inclination of the correlativity among scanning lines obtained within a predetermined period.

    摘要: A piping travelling apparatus having a plurality of continuous treads driven by motors through transmission gearing. The continuous treads are mounted to a frame and spaced apart a predetermined distance peripherally of the inner wall surface of the piping. At least one of the continuous treads is kept in contact with the inner wall surface of the piping no matter what the posture of the apparatus may be, so that the apparatus can travel without any trouble even if its posture undergoes a change when it moves along elevations and depressions on the inner wall surface of the piping or negotiates the boundary between different levels of the inner wall surface or bends of the piping. The apparatus enables a travel through piping of relatively small diameter having vertical or steeply slanted pipes to be made without any trouble.
