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.

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.

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.

摘要:
A magneto-optical recording medium includes a substrate on which light is incident, a first magnetic layer provided at the substrate side, and a second magnetic layer provided on the first magnetic layer. The first magnetic layer is an in-plane magnetization film at room temperature and becomes a perpendicular magnetization film at a temperature between room temperature and a Curie temperature thereof. The second magnetic layer has a Curie temperature lower than that of the first magnetic layer and is a perpendicular magnetization film. The direction of magnetization of the first magnetic layer is anti-parallel to the direction of magnetization of the second magnetic layer in a state in which the first magnetic layer and second magnetic layer are stable with respect to each other by exchange-coupling.

Disclosed herein is a tapping screw (1) exerting an excellent anti-loosening effect with regard to a workpiece made of a soft material such as resin and an aluminum alloy. The tapping screw (1) includes a shaft part (3), and a normal thread (10) which is formed on the outer circumferential surface of the shaft part. A clearance groove (20) is formed by cutting out a portion of a ridge of the normal thread, and an engaging protrusion (30) is provided on a bottom of the clearance groove along a portion or an entirety of an edge of the bottom that continuously extends from a flank surface of the normal thread. The tapping screw (1) exerts an excellent anti-loosening effect even when a workpiece expands, contracts or oscillates because the engaging protrusions (30) are embedded into portions of the workpiece which have been embedded into the clearance grooves (20).

The object of the present invention is to provide a rubber crawler in which a shape of the central lug viewed from a lateral side of the rubber crawler is approximately in the form an arc. Therefore, at a time of driving of the rubber crawler repeating back and forth movement, even if a large resisting force from the road surface due to an impediment, such as gravel, is subjected to the central lug particularly disposed close to a sprocket engagement section, the resisting force can be parried for dispersion to a suitable degree by such arrangement, so that there is no possibility of early peel occurring in the central lug or such peeling is prevented from extending to tread members connected thereto; thus, the life is prolonged.
