    摘要: An electroless copper plating solution using glyoxylic acid as a reducing agent, which is small in the reacting quantity of Cannizzaro reaction, does not largely cause precipitation of the salt accumulated in the electroless copper plating solution by the plating reaction and Cannizzaro reaction, and can be used stably over a long period of time.

    摘要: A magnetooptical recording medium has a first magnetic layer which is an in-plane magnetization film at both room temperature and high temperatures and changed to a perpendicular magnetization film at intermediate temperatures, and a second magnetic layer which is composed of a perpendicular magnetization film. The recording medium enables realization of high S/N reproduction of information recorded at a pitch below the diffraction limit of light with a simple structure, and further improvement in linear recording density and track density.

    摘要: Disclosed is a guide lug composition for a rubber track comprising 5 to 40 parts by weight of a fatty acid amide based on 100 parts by weight of a raw rubber material; or comprising 5 to 40 parts by weight of a Ultra High Molecular Weight Polyethylene (UHMW-PE) powder based on 100 parts by weight of a raw rubber material; or comprising 5 to 40 parts by weight of a fatty acid amide and 5 to 40 parts by weight of a UHMW-PE power based on 100 parts by weight of a raw rubber material. The guide lug composition serves to reduce abrasion of or damages to a guide lug, to improve the characteristics in preventing the rubber track from slipping off a wheel, which is called “detracking”, to reduce friction loss when the guide lug contacts and collides with the wheel thereby reducing energy losses.

    摘要: A magnetic thin film element is provided with a magnetoresistive film including a first magnetic layer composed of a perpendicular magnetization film, a second magnetic layer composed of a perpendicular magnetization film having a higher coercive force than that of the first magnetic layer, and a nonmagnetic layer interposed between the first magnetic layer and the second magnetic layer. The resistance of the magnetoresistive film varies depending on whether or not the magnetic spins of the first magnetic layer and the second magnetic layer are in the same direction.

    摘要: A magneto-optical recording medium includes a first magnetic layer and a second magnetic layer. The first magnetic layer is a horizontal magnetization layer at room temperature but a perpendicular magnetization layer at a raised temperature. A transition temperature of the first layer continuously or stepwise increases from a light incidence side thereof light in a film thickness direction. The second magnetic layer is a perpendicular magnetization layer both at room temperature and at the raised temperature. In reproduction of information, an optical beam is applied onto the magneto-optical recording medium in which information is recorded by directions of magnetization. The information recorded in the second magnetic layer is transferred to the first magnetic layer and the information is read by the magneto-optical effect.

    摘要: In a magneto-optical recording medium, a first magnetic layer for participating in reproduction of information is laminated on a substrate. A second magnetic layer for storing information is laminated on the first magnetic layer. A third magnetic layer having a Curie temperature lower than those of the first and second magnetic layers is disposed between the first magnetic layer and the second magnetic layer. A magnetization of a region of the first magnetic layer adjacent to a region of the third magnetic layer the temperature of which is above the Curie temperature of the third magnetic layer is aligned with the direction of magnetization of a region around the region of the first magnetic layer.
