Abstract: A holder for holding a TV camera or like camera selectively serves as a clamp, a breast support arm, a tripod and a grip. The camera is mounted on one end of a first pipe, while a second pipe is telescoped in the first pipe to be slidable therealong. First and second clamp seats are mounted on the second pipe. The second clamp seat is provided with a rotatable arm which is slidable along and rotatable about the axis of the second pipe. The clamp, breast support arm or grip function is attained by rotating the rotatable arm to a predetermined fixing position and moving the second clamp to be predetermined fixing position on the second pipe. Two legs are nested in the second pipe such that when the tripod function is desired the legs are pulled out from the second pipe, opened by a predetermined angle away from each other, and fixed in the opened position.

Abstract: A method for controlling the width of material in hot strip rolling through a train of alternately arranged vertical and horizontal roughing roll stands. The method restricts the width variation of the strips at the delivery side of the roughening rolls caused by the difference in temperature distribution in the widthwise direction of the strips between skidded areas and non-skidded areas by controlling the degrees of roll opening of a vertical roll stand based on the measurement of the width of the material to be rolled measured by a width meter, the vertical roll stand being disposed downstream of the measuring point.
