Abstract: A multi-layered heat resistant metal tube is disclosed. This tube has excellent anti-coking characteristics and is suitable for use under the conditions where carbon tends to deposit and accumulate thereon due to contacting with hydrocarbons at a high temperature. The tube is made by forming weld-mounted overlaid layer of a Cr—Ni—Mo alloy by building-up welding over the inner surface and/or the outer surface of a substrate tube made of a heat resistant metal. The Cr—Ni—Mo alloy consists essentially of, by weight %, Cr: 36-49 wt %, Ni: 35-63 wt % and Mo: 0.5-5 wt %. Building-up welding is preferably carried out by PPW (Plasma Powder Welding) in which the filler metal is supplied in the form of powder.

Abstract: A magnetic thin film memory includes a stack of magnetic thin film devices each comprising a first magnetic layer, a second magnetic layer of higher coercive force than the first magnetic layer on the first magnetic layer, and a non-magnetic layer between the first magnetic layer and the second magnetic layer. A conductive write wire separated from each magnetic thin film device by an insulator enables the application of a magnetic field. A pair of electrodes enables electric current flow through the magnetic layers in order to detect changes in magnetoresistance dependent on information recorded in the devices.

Abstract: A magneto-optic recording medium of the present invention has a transparent substrate. A reproducing layer is stacked on the substrate, and remains in an in-plane magnetic state at room temperature and is transformed into a perpendicular magnetic state at an increased temperature. A first recording layer for storing information therein is stacked on the reproducing layer. In the first recording layer, the perpendicular magnetic state is maintained in a temperature range of from room temperature to the Curie temperature. A second recording layer for storing information therein is stacked on the first recording layer. In the second recording layer, the perpendicular magnetic state is maintained in a temperature range of from room temperature to the Curie temperature. The sub-lattice magnetic moment of an element forming the second recording layer is oriented in the direction opposite to the magnetic moment of the first recording layer. A same type of elements being used for the first and second recording layers. The rotation of the plane of polarization of incident light generated in the reproducing layer at a magnetic wall domain is canceled by the rotation angles of the planes of polarization of the incident light generated in the first and second recording layers.

Abstract: A method of recording and reproducing information on a magnetooptical recording medium includes the steps of irradiating the medium with laser light to heat a reproducing layer at least to a predetermined temperature at which the layer is vertically magnetizable, thereby rendering the reproducing layer vertically magnetizable and causing it to effect exchange coupling with a recording layer. The method also includes the step of applying a vertical external magnetic field to a portion of the medium irradiated with the laser light and applying a horizontal external magnetic field, weaker than the vertical external magnetic field, during recording and reproducing of data.
