    摘要： Disclosed is a magnetic material which exhibits an improved saturation magnetic flux density and an improved magnetic anisotropy and, thus, is adapted for use as a raw material of a permanent magnet or a bond magnet of a high performance. The magnetic material is represented by a general formulaR.sub.x Co.sub.y Fe.sub.100-x-y (I)where R is at least one element selected from the rare earth elements, x and y are atomic percent individually defined as 4.ltoreq.x.ltoreq.20 and 0.01.ltoreq.y.ltoreq.70, and Co and Fe occupy 90 atomic percent or more in the principal phase of the compound.

    摘要： There is provided a four-cycle engine which can appropriately circulate oil in an engine regardless of a tilted condition with a simple structure. A crankcase (4) of a four-cycle engine (1) has a crank room (41) which rotatably supports a crankshaft (10) and an oil room (42) which is provided adjacent to the exterior of the crank room (41). The crankcase (4) also has partition walls (43) and (44) which partition the interior of the crankcase (4) into the crank room (41) and the oil room (42), respectively, and a communication path (45) which communicates the crank room (41) with the oil room (42). The partition walls (43) and (44) each has a cross section formed in a substantially V shape, and the communication path (45) is formed at an apex between the partition walls (43) and (44).

    摘要： A magnetic recording element includes a first fixed layer having a first and second face and having a magnetization direction fixed in a direction penetrating the first and second face. A free layer has a third and fourth face, a magnetization easy and hard axis both extending along the third or fourth face, and a magnetization direction which changes according to a direction of a current flowing through the first and fourth face with a magnetic field applied in a fixed direction or according to a direction of a magnetic field applied to the free layer with a current flowing through the first and fourth face in a fixed direction. A nonmagnetic first intermediate layer is provided between the second and third face. A magnetic field generating layer applies a magnetic field smaller than the anisotropy field of the free layer to the free layer along the magnetization hard axis.

    摘要： A magnetic recording element includes a first fixed layer having a first and second face and having a magnetization direction fixed in a direction penetrating the first and second face. A free layer has a third and fourth face, a magnetization easy and hard axis both extending along the third or fourth face, and a magnetization direction which changes according to a direction of a current flowing through the first and fourth face with a magnetic field applied in a fixed direction or according to a direction of a magnetic field applied to the free layer with a current flowing through the first and fourth face in a fixed direction. A nonmagnetic first intermediate layer is provided between the second and third face. A magnetic field generating layer applies a magnetic field smaller than the anisotropy field of the free layer to the free layer along the magnetization hard axis.
