Abstract: A method of preventing the subsequent breakage of webs running in a rotary press which would be caused by a first broken web. In this method, when a signal of web breakage is received from any one of web breakage sensors which are provided to sense the breakage of any of the running webs, a nip pressure signal is changed in accordance with the number of webs still running, and is sent to a nip pressure controller to decrease the nip pressure of a triangular former drag pressing roller and nipping roller, to prevent the multiple breakage of webs.

Abstract: This invention relates to an improved sprayer cap structure associated with a neck portion of a bottle-shaped container for providing a liquid spraying operation or a liquid streaming operation. The sprayer cap includes an inner plug integrally formed adjacently with first and second hollow cylindrical portions in a top-walled cylindrical section. The cylindrical section is perforated with a first hole communicating with the bottom of the container through a pipe, and is also formed with a first valve chamber provided with a blocking valve at the upper position thereof and with a check valve at the lower position thereof. The cylindrical section further is perforated with a second hole and a third hole spaced longitudinally, and formed with a second valve chamber under the second hole, the second valve chamber being provided with a blocking valve at the upper position thereof. A nozzle unit is formed with a spinner slot capable of communicating with the first and second holes of the inner plug.

Abstract: A vacuum vapor deposition system including a high-vacuum vapor deposition chamber provided with a rotary cell around which band steel is wound as it is passed through the chamber. A crucible for molten metal has a hood for guiding vapor of said metal to a vapor deposition port opposed to the rotary cell, and arcuate covers connected to the hood at the entrance and exit positions of the band steel. The vapor deposition port is spaced slightly from the rotary cell so that the covers will not come into contact with the band steel. A heater is provided for heating the surface of the rotary cell up to a temperature equal to or higher than a reevaporation temperature of the metal under a vapor pressure of the vapor of the metal in the proximity of the rotary cell so that the metal will not be deposited onto the opposite end portions of the rotary cell which are not covered by the band steel.

Abstract: A container in which a recess for containing a coiled spring is formed at a shaft hole opening in a cover and a container. A connecting portion for connecting the other end of the coiled spring is formed at the other of the cover and the body in such a manner that the connecting portion is substantially oppositely formed to the recess at the shaft hole opening. A connecting piece capable of temporarily connecting the other end of the coiled spring is formed, and a packing elastically contacted with the lower surface of the cover of closed state is associated intimately with the upper end of the bottomed cylindrical container body. Thus, the container can by simply produced by readily associating the cover and the container body and can also assure the sealability between the cover and the body.
