摘要:
A magneto-optical recording medium having an improved durability or reliability is obtained by providing a protecting layer of an alloy of titanium with one or more of chromium, rhenium and tantalum. This titanium alloy protecting layer has an improved resistance to oxygen, water, chlorine, and acids, etc. and provides an improved resistance to the environment and attacks from the synthetic resin substrate or other layers constituting the medium, such as a dielectric layer and a reflecting layer.

A magneto-optical layer sensitive to a light with a short wavelength such as 400 to 550 nm and having a perpendicular magnetization can be deposited on a substrate at a room temperature. The magneto-optical layer is of a tertiary polycrystalline having a composition, for example, Co.sub. aPt.sub.b Ru.sub.c where 20.ltoreq.a.ltoreq.70, 10.ltoreq.b.ltoreq.70, 10.ltoreq.c.ltoreq.60 and a+b+c=100 or Co.sub.d Pt.sub.e Re.sub.f where d.ltoreq.80, 5.ltoreq.e, 5.ltoreq.f, 40.ltoreq.4d-5f and d+e+f=100, and has an easy magnetization axis perpendicular to the main surface of the layer.

A plasma treatment apparatus for forming a thin film on a substrate in a vacuum vessel includes a magnetic field generator which can be positioned inside or outside the vacuum vessel, and a microwave source. The magnetic field strength is controllable such that an electron cyclotron resonance (ECR) area is defined near the substrate. The magnetic field generator can be arranged so that plasma and reactive gas introduction ports are on the microwave introduction side of the ECR area and the substrate is on the opposite side of the ECR area. Alternatively, a gas introduction port can be positioned such that reactive gas is introduced into the ECR area or onto the substrate.

An amorphous alloy consists of iron and tellurium and has a tellurium content of from about 14 to 90 atomic%. The amorphous alloy can be utilized as an information material for optical recording and the like, and as a magnetic material and the like. The corrosion resistance and particularly heat resistance are excellent.
摘要:
Heat-resistant filters 6, 7 are disposed at the upstream side of a catalyst bed 9. These heat-resistant filters 6, 7 perform filtration to completely catch and remove the smoke particles suspended by the exhaust gas, so that the undesirable attaching of the smoke particles to the catalyst bed 9 is fairly avoided. Also, means are provided to regenerate the heat-resistant filters simply by burning the smoke particles attaching to these filters. In another embodiment, a heat-resistant filter 24 and a catalyst bed 26 are shaped to have hollow cylindrical forms and are superposed to each other. For regenerating the heat-resistant filter 24, hot air is introduced into the filter 24 by the action of a high pressure burner 28 or a vacuum generating section 33. The heat-resistant filter 24 and the catalyst bed 26 are accomodated by a single case 21.

摘要:
When a file having coated thereon an electrically conductive coating which is transparent in a highly oxidized state and non-transparent in a lowly oxidized state or in a reduced state, such as a coating of indium oxide, is heated electrically or by laser beams or oxidized and/or reduced by electrolytic reaction, images consisting of transparent and non-transparent areas are formed on the film. This can be utilized, for example, in a facsimile system.
