摘要:
In a continuous vacuum vapor deposition system, a reduced-pressure chamber is partitioned into a plurality of sub-chambers by seal devices each formed by one set of three pinch rolls arrayed in parallel on one plane or a single seal roll, and a pair of seal bars positioned on the same plane on the respective sides of the pinch roll or seal roll. Gaps between the pinch rolls or seal roll and seal bars are adapted to allow the base plate portions on the inlet side and on the outlet side, respectively, to pass therethrough. In each of the reduced-pressure sub-chambers are disposed a pair of deflector rolls so that the base plate portions on the inlet side and on the outlet side may be wrapped respectively around the pinch rolls or seal roll with a wrapping angle of 10 degrees or more.

Disclosed is a combined continuous plating apparatus for hot-dip plating and vacuum deposition plating characterized in that the outlet of the gas reduction annealing furnace of a conventional continuous hot-dip plating apparatus and the inlet of the seal roll chamber of a known continuous vacuum deposition plating apparatus are connected through a pressurized chamber in order to prevent invasion of hydrogen-containing reduction gas into the vacuum deposition chamber, whereby is prevented the possibility of the hydrogen-containing gas causing an explosion should air leak into the vacuum deposition chamber.

摘要:
For vacuum deposition plating steel strip, a vacuum deposition plating apparatus is used including an inlet-side vacuum sealing device provided in front of a vacuum deposition plating chamber, with an inlet-side inactive gas replacement chamber provided between the inlet-side vacuum sealing device and an annealing furnace. An outlet-side vacuum sealing device is provided at the rear of the vacuum deposition plating chamber, with an outlet-side inactive gas replacement chamber provided between the outlet-side vacuum sealing device and the atmosphere. An inactive gas circulating/purifying device circulates an inactive gas from vacuum chambers of both the vacuum sealing devices to atmospheric pressure chambers of both the vacuum sealing devices and removes water, oil and oxygen from the inactive gas. Oxygen and hydrogen in the inactive gas are regulated to provide 60 ppm or less of oxygen and 0.2 to 2.0% of hydrogen, and also to regulate the dew point of the inactive gas to -50.degree. C. or less. Further, a pressure P.sub.1 in the annealing furnace, a pressure P.sub.2 in the inlet-side inactive gas replacement chamber, and a pressure P.sub.3 in the outlet-side inactive gas replacement chamber are maintained at atmospheric pressure or more. A value of P.sub.1 -P.sub.2 can be kept at 0 mmAq or more, and the concentration of hydrogen in the inlet-side inactive gas replacement chamber is held to 2.0.degree. or less.

In the continuous vapor deposition coating of a metal strip, the coating amount can be rapidly changed by keeping the vapor flow at acoustic velocity and changing the cross-sectional area of the vapor path.
摘要:
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.
摘要:
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.
摘要:
An improved vacuum vapor-deposition apparatus comprises an evaporation tank for holding and evaporating vapor deposition material, a hood covering the top of the evporation tank and extended up to its outside in the horizontal direction, inlet and outlet ports of a band to be vapor-deposited, which are opened in the hood so as to penetrate a central portion of the extension on the outside of the evaporation tank, and a vacuum tank covering the evaporation tank and the hood entirely and having sealing devices for carrying in and carrying out the band to be vapor-deposited at the positions corresponding to the inlet and outlet ports in the hood. Vapor deposition is effected within the hood simultaneously onto the both front and rear surfaces of the band to be vapor-deposited. Preferably, the vacuum vapor-deposition apparatus further comprises a vapor amount control device for controlling a vapor amount of the evaporated material led to the both front and rear sides of the band to be vapor-deposited within the hood, and a vapor-deposited surface area control device provided at least on one side of the front and rear sides of the band to be vapor-deposited within the hood for controlling a vapor-deposited surface area of the band to be vapor-deposited. Then, vapor-deposition of different thickness is effected within the hood onto the front and rear surfaces of the band to be vapor-deposited.
