Abstract: To provide a user with an effect switcher having improved usability. The effect switcher includes an output terminal that outputs a plurality of first video signals to be transmitted to a multi-view processor, as an optical multiplex signal. For example, the effect switcher further includes: an output terminal that outputs a single second video signal to be transmitted to the multi-view processor; and an information insertion unit that inserts, into the optical multiplex signal, information for designating a display region of an image based on the single second video signal on a screen on which an image based on each of the first video signals is displayed.

Abstract: A tension balancer which includes an axis body including a latch part, a column shaped main body including a bottom part which has at least two first through holes arranged at equal intervals in a concentric circle from the center, and an open upper part, a spring base housed within the main body and having an aperture for joining an end of the axis body to the center, and at least two second holes arranged at equal intervals in a concentric circle from the center, an upper lid having an aperture for pushing through the main body of the axis body to the center, and at last two second through holes arranged at equal intervals in a concentric circle from the center, the upper lid being screwed to the main body by a bold and nut which passes through the first, second and third through holes, and at least two or more spring unit groups sandwiched between the spring base which is housed within the main body and the upper lid.

Abstract: A digital processing circuit for a video signal digital by processing a composite video signal. More specifically, a composite video signal is separated into a luminance signal and a color signal by means of a Y/C separator (10). The color signal separated is converted into a signal having low frequency by means of a low frequency converter (11) that the signal having low frequency is converted into a digital signal by means of an A/D converter (13). The luminance signal separated is converted into a digital signal by means of an A/D converter (12). Digital signals are transmitted through a transmission line (5). The transmitted luiminance signal is converted into an analog signal by means of a D/A converter (14) so that the analog signal is supplied to a Y/C mixer (17).

Abstract: An apparatus for heat-treating pipes comprising a furnace chamber for accommodating a plurality of pipes as arranged in parallel, a chain conveyor disposed in the furnace chamber for transporting the pipes in a direction at right angles to the axes of the pipes, and a plurality of stopper means for stopping the pipes intermittently at suitably spaced-apart positions in the path of transport by the chain conveyor and causing each of the pipes to rotate about its own axis in cooperation with the chain conveyor. Since the pipe is intermittently stopped and rotated about its own axis during heat treatment, the pipe is free of thermal deformation to an elliptical shape. Pipes can be heat-treated in succession in a small space, therefore with a very high efficiency. The motion of the chain conveyor is utilized for rotating the pipe without necessitating any additional device for the rotation.
