A lowering collision avoidance device includes a container detector, a rope winding speed detector, a rangefinder for detecting the distance to an adjacent container, a rope length detector, and a controller which controls a hoisting/lowering drive motor, thereby controlling the lowering speed, in such a manner that when the container detector becomes ON, a lowering stop action is performed to start decreasing the lowering speed at a predetermined rate; even during this period, the remaining lowering distance and a normal stopping distance are computed; and when the container detector becomes OFF for one period of swing computed from the rope length detected by the rope length detector, and after a judgment is made that the risk of collision of a lowered container with the adjacent container has vanished, lowering is resumed if the remaining lowering distance is larger than the normal stopping distance, or an emergency stop action is performed if the remaining lowering distance is not larger than the normal stopping distance. Thus, the container can be lowered rapidly to a place where obstacles such as containers stacked in layers are located, with the collision of the container with the obstacle being prevented.

A lowering collision avoidance device includes a hoisting accessory swing detector, a rope winding speed detector, an arithmetic unit, a rope winding speed controller, and if desired, a rope length detector. The arithmetic unit computes a command value for the lowering speed based on the results of comparison between the amount of swing of a hoisting accessory detected by the hoisting accessory swing detector and a predetermined threshold level or a plurality of predetermined threshold levels; the direction of changes in the amount of swing computed based on the amount of swing of the hoisting accessory; and the lowering speed detected by the rope winding speed detector. The rope winding speed controller controls the lowering speed based on this command value. The arithmetic unit also predicts maximum displacement by swing based on the amount of swing of the hoisting accessory, the positional change rate of the hoisting accessory computed based on this amount of swing, and the period of vibration of the hoisting accessory computed from the rope length detected by the rope length detector, and computes a command value for the lowering speed based on the results of comparison between the maximum displacement and a predetermined threshold level. The rope winding speed controller controls the lowering speed based on this command value as well.

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. A heater is also provided for heating the surfaces of the hood and the covers up to a temperature equal to or higher than such reevaporation temperature of the metal so that metal will not be deposited onto the hood and the covers.

A sputtering apparatus including two electrodes, a sputtering target disposed on one of the electrodes, and a gas supply for supplying a discharge gas in a vacuum to produce an electric discharge between the two electrodes and whereby particles sputtered from the target due to impact thereon of ions produced by the discharge, are deposited on a substrate. The target disposed on one electrode is formed into an elongated band and the other electrode is disposed so as to enclose the target. The other electrode is also provided with a magnet for producing a magnetic field thereon, and further includes a narrow elongated slot which defines a narrow sputter particle outlet. The narrow sputter particle outlet permits a pressure to exist near the electrical discharge which is higher than the pressure near the substrate. According to a preferred embodiment, the sputtering apparatus has an ion source combined integrally therewith.

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.

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.
