During sputtering for use in thin film deposition, anomalous discharge is prevented from generating between a target and a backing plate, and a target presser. In the target presser also serving as an earth shield and a deposition preventing plate, an insulating member staying in contact with the sputtering target or the backing plate is provided with a recess constituted of two or more different depths so that the recess does not come in contact with the sputtering target or the backing plate.

There is disclosed a prepreg including noncircular cross-section carbon fibers and a matrix resin having a flexural elastic modulus of 2.7 GPa or more and a water absorption of 3.4% or less under hot-wet conditions after curing; and another prepreg including carbon fibers and a matrix resin having an open-hole compression strength under hot-wet conditions and a compression strength after impact under room-temperature conditions of a quasi-isotropic material after curing of each 275 MPa or more. Carbon fiber-reinforced composite materials produced by curing these prepregs are excellent in open-hole compression strength under hot-wet conditions and in compression strength after impact, and can be suitably used especially as an aircraft primary structure material.

摘要:
The object of the present invention is to provide carbon fibers with high tensile strength as a resin impregnated strand even if the single filaments constituting the carbon fibers are thick. The carbon fibers of the present invention consisting of a plurality of single filaments are characterized by satisfying the following relation:.sigma..gtoreq.11.1-0.75dwhere .sigma. is the tensile strength of the carbon fibers as a resin impregnated strand (in GPa) and d is the average diameter of the single filaments (in .mu.m). The carbon fibers can be preferably used as a material for forming energy-related apparatuses such as CNG tanks, fly wheels, wind mills and turbine blades, a material for reinforcing structural members of roads, bridge piers, etc., and also a material for forming or reinforcing architectural members such as timber and curtain walls.

More than two pressure reducing chambers 6 to 9 are located on both the upstream and the downstream of vacuum processing housings 11 and 12. Each of the pressure reducing chambers 6 to 9 includes a film conveying means 30, a vacuum exhausting means, and a gate valve 20 provided with a resilient member for closely holding down the running film 1 to seal off the vacuum state of a belt-like passage of the gate valve 20. As the pressure reducing chambers 6 to 9 are protected with their specific gate valve belt-like passage arrangement from reduction of the vacuum state and located respectively on the upstream and downstream sides of the vacuum processing units 11 and 12, the vacuum state in the continuous vacuum processing apparatus will be maintained to a desired level. While the running film 1 is being conveyed, the gate valves 20 at the first and second stages are actuated alternately for opening and closing after vacuum evacuation.

When forming a conductor film of Ag, Au, Cu, Al on a substrate of ceramics or glass, an adhesive layer of Cr, NiCr is formed on the substrate, a mixed layer of adhesive layer material and conductor film material is formed on the adhesive layer, and a conductor film is formed on the mixed layer. According to this method, even if film forming is conducted below the temperature for inducing diffusion on the interface of the conductor film and adhesive layer, for example, below 100.degree. C., an alloy layer of adhesive layer material and conductor film material is present on the interface of the adhesive layer and conductor film to be closer to bulk state, and the attraction between molecules is increased, so that the bonding strength of the conductor film and adhesive layer is enhanced. Therefore, at 100.degree. C. or more, a conductor film which hardly causes peeling may be formed on the substrate to be used in electronic components which vary in electric characteristics or on the film form substrate which deforms thermally.
