Abstract: A printing machine driven by one electric motor or by individual electric motors controllable by their own respective associated control systems. The control systems contain a subsystem observer or a total system observer, which obtains from the actual rotational angle speed (.omega..sub.ist) or the actual rotational angle (.phi..sub.ist) as well as from the electric-current or moment target value or actual value of the electric motor, an observed load torque (M.sub.LAST), which is supplied to the adjustment element as a component of the target moment (M.sub.soll). This signal can be applied via a differentiating filter or, in addition, via the proportional element, to the summing point. Alternatively to or in conjunction with the observer, a periodic compensation controller is provided in the control loop. The periodic compensation controller provides deviation-control for periodic disturbances and obtains, from the differential angular speed (.omega..sub.D), a component (M.sub.

Abstract: An object of the invention is to provide a seamless ink ribbon which makes it possible to markedly prolong the printing life, even with rather rough-faced printing paper such as paper made in China as well as a method of manufacturing the same.The seamless ink ribbon of the invention comprises a statically hot-pressed seamless woven fabric with multifilament yarn as warp and as weft. This ribbon is manufactured by subjecting a seamless woven fabric obtained by double weaving using multifilament yarn as warp and as weft to static hot pressing, without applying any shearing force, to thereby reduce the thickness of the fabric by 15 to 50% as compared with the thickness before pressing. The seamless fabric is fuse-cut to the ribbon width either before or after hot pressing.

Abstract: An ink jet recording apparatus, which is provided with a blade for wiping the surface of discharge openings of an ink jet recording head, and a blade cleaner for removing ink adhering to the blade, comprises a cleaning device for cleaning the blade by enabling the blade cleaner and the blade to reciprocate correlatively. This cleaning device causes the blade cleaner to be in elastic contact with the blade intensively without rotating the blade cleaner when the blade moves forward, and for causes the blade cleaner to rotate to be in elastic contact with the blade weakly when the blade moves backward. With the structure thus arranged, it is possible to reduce the spraying of ink from the blade into the interior of the ink jet recording apparatus significantly. Therefore, the surface of discharge openings of the ink jet recording head can be cleaned by a blade in good condition to make it possible to operate cleaning in the most suitable mode.

The controller and remaining paper detection controller inhibit the print switch from setting the printing operation mode when a remaining paper sheet is detected by the remaining paper detection apparatus.

Abstract: An improved end-seal carrier assembly for supporting a seal in a seal-type continuous dampener. The seal is supported by a backing plate and pressed against the ends of the dampener's rollers. A carrier shaft is fixedly mounted to the backing plate. A shaft housing is mounted to the sideframe and has a hole extending longitudinally there through into which the shaft is mounted so to rotationally and longitudinally translate with respect to the sideframe. A coil spring is wound about a portion of the carrier shaft and has a first spring end operatively engaging the backing plate and a second spring end operatively engaging the shaft housing. The coil spring is configured to induce both a compressive and torsional bias between the backing plate and the sideframe. The shaft housing is rotatable for winding the coil spring and thereby establishing the torsional bias.
