Abstract: The present invention provides a film deposition system capable of effectively cooling a work having a large volume, and a film deposition method using this system. The film deposition system has, within a vacuum chamber 1, an evaporation source 3 for forming a film on a work 2 and a cooling device 4 for cooling the work 2, characterized in that the work 2 has an internal space 15 communicating with the outside through an opening part 14, and the cooling device 4 is insertable to and drawable from the internal space 15 through the opening part 14 of the work 2 to cool the work 2 from the inside.

Abstract: An ion implantation apparatus is intended to perform the ion implantation for the desired surface of a target irrespective of the surface geometry thereof, and to simplify the structure. The apparatus includes a vacuum chamber, and a plurality of arc ion sources for emitting ion beams on the surface of the target disposed within the vacuum chamber. A plurality of arc ion source mounting openings are formed on the vacuum chamber. One or more of arc ion sources necessary for emitting ion beams on the desired surface of the target are airtightly mounted on the openings opposed to the above surface.

Abstract: A cathodic arc deposition system includes a cathode made of a film forming material, a shield surrounding a circumferential side of the cathode with a gap, a vacuum chamber having the cathode and the shield therein, and a substrate to have deposited at a surface thereof an ionized film forming material by generating an arc discharge between the cathode and the anode. Either the cathode or the shield is adjusted in height so as to keep the upper edge of the shield at substantially the same vertical level as the upper edge of the cathode.

Abstract: This invention relates to a joint for risers, and particularly to a telescopic joint suitable for expandably connecting composite-pipe type riser pipes provided internally with tubing pipes. Its structural features reside in that connectors adapted to connect risers in up-and-down relationship are slidably engaged with each other and air cylinders capable of cancelling volume changes of the engaged portions, which volume changes occur due to expansion and contraction movements of the connectors, are communicated to the spacing of the engaged portions, and hydraulic cylinders adapted to cancel volume changes of the engaged portions of an internally-threaded nose portion and an externally-threaded nose portion, which engaged portions serve to communicate the upper and lower tubing pipes to each other, is communicated with the spacing of the engaged portions of the nose portions.
