Abstract: A plasma gun of the present invention includes: a container having a plasma outflow opening; a cathode (18) which is disposed inside the container to generate plasma by discharge; an auxiliary anode which is disposed to be able to be located between the plasma outflow opening and the cathode and is able to receive the plasma generated by the cathode; an exhaust valve for exhausting air from and sealing an inside of the container; and a plasma flow-out preventing/allowing device which prevents the plasma, having been generated by the discharge of the cathode, from flowing out from the plasma outflow opening and allows the plasma to flow out from the plasma.

Abstract: A sheet plasma film forming apparatus includes: a pressure reducing container; a plasma gun; an anode; plasma flowing means; a sheet plasma converting chamber as part of the pressure reducing container; a pair of permanent magnets which forms a sheet-shaped plasma; and a film forming chamber as a part of the pressure reducing container. The pressure reducing container includes first and second bottle neck portions that are openings of the film forming chamber formed such that the plasma flows from the sheet plasma converting chamber through the first bottle neck portion to the film forming chamber, and the flown sheet-shaped plasma flows through the second bottle neck portion to the anode. In the thickness direction of the sheet-shaped plasma, a size of the first and second bottle neck portions is smaller than an internal size of the film forming chamber.

Abstract: A sheet plasma film forming apparatus (100) of the present invention includes: a plasma gun (40) which can emit source plasma (22) in a transport direction; a sheet plasma converting chamber (20) including a transport space (21) extending in the transport direction; a pair of first magnetic field generating means (24A, 24B) disposed so as to sandwich the transport space (21) such that same poles thereof face each other; a film forming chamber (30) including a film forming space (31) which communicates with the transport space (21); and a pair of second magnetic field generating means (32, 33) disposed so as to sandwich the film forming space such that different poles thereof face each other, wherein: while moving in the transport space (21), the source plasma (22) is converted by a magnetic field of the pair of first magnetic field generating means (24A, 24B) into sheet-shaped plasma spreading along a main surface S including a center; and while moving in the film forming space (31), the sheet-shaped plasma 2

Abstract: A plasma film deposition system increases plasma density and improves sputtering efficiency by not generating a corner of a sheet plasma and can be operated safely by preventing occurrence of the corner in sheet plasma. The system comprises: a plasma gun capable of discharging source plasma toward a transport direction; a sheet plasma deformation chamber; a pair of magnetic field generating means provided such that same polarities thereof face each other; a film deposition chamber; and a forming magnet coil provided upstream of the pair of magnetic field generating means in the transport direction. The magnetic field generating means and the forming magnet coil generate a magnetic field whose magnetic flux densities in the transport direction are substantially constant at portions of a transport center and their vicinity portions, the portions corresponding to the forming magnet coil and the magnetic field generating means.

Abstract: To extend the service life of a latch of a plug housing and facilitate assembly and aligning operations of an optical connector. The optical connector includes a latch provided in a cantilever form on an external surface of the optical connector and deformable for attachment/detachment with respect to an adaptor, and an excessive deformation preventing unit that prevents excessive deformation of the latch.
