摘要： Disclosed is a rare earth-based, magnetically anisotropic permanent magnet material consisting of a rare earth element, e.g., neodymium or praseodymium, iron optional in combination with cobalt and boron and having excellent magnetic properties by virtue of the magnetic coupling between the magnetically hard and soft phases. The magnet material has a structure consisting of crystalline particles of, e.g., Nd.sub.2 Fe.sub.14 B, having a particle diameter of 1 .mu.m or larger and fine crystals of iron of submicron size in a rod-shaped or platelet form precipitated within each crystalline particle of Nd.sub.2 Fe.sub.14 B. This magnet material can be prepared by several different methods including, for example, a solid phase reaction of an intermetallic compound of Nd.sub.2 Fe.sub.17 with boron to effect a double decomposition reaction producing Nd.sub.2 Fe.sub.14 B and iron.

摘要： A soft magnetic under layer (SUL) is formed on a non-magnetic substrate by an electroless plating method. The SUL formed by plating is subjected to magnetic field heat treatment on conditions that the heat treatment temperature is 150° C. to 350° C., a magnetic field applied to the substrate has a strength of 50 oersteds (Oe) or more, and the treatment time is selected within a range of five minutes to ten hours. Through the magnetic field heat treatment, magnetic anisotropy is obtained with a difference (δH=Hd−Hc) of 5 oersteds (Oe) or more in terms of absolute value between a magnetization saturation magnetic field strength (Hd) in the in-plane radial direction of a soft magnetic film and a magnetization saturation magnetic field strength (Hc) in the in-plane circumferential direction of the soft magnetic film, and the magnetic anisotropy is symmetric with respect to the axis of the substrate.

摘要： A seal structure has one metal gasket arranged between a pair of casings. The metal gasket is provided with a planate outer peripheral portion and a bead portion which is formed by rising up from an inner peripheral end portion of the outer peripheral portion, and is arranged so that the bead portion comes into contact with the one casing, and the outer peripheral portion comes into contact with the other casing. The bead portion elastically deforms so as to reduce its height and the outer peripheral portion elastically deforms on the basis of the elastic deformation of the bead portion, when the metal gasket is pinched by the pair of casings, and a leading end of the outer peripheral portion comes into contact with one casing at this time, whereby any gap in which salt water stays is not formed between one casing and the metal gasket.

摘要： A vehicle drive unit, for quickly recovering a grip even if a wheel slips, in which in a slip state or at a time when the slip state is going to be generated, by pulsating a torque applied to the wheel, an angular velocity W of the wheel is changed so as to change the slip ratio S close to a slip ratio at which a friction coefficient becomes maximum, and thus, an average of a friction coefficient μ is enlarged and an average of a vehicle driving force F generated by a wheel is enlarged. Since the vehicle driving force is enlarged, the vehicle is accelerated and is easily gripped. Further, in a grip state or at a time of traveling at a high velocity, a vibration and an undesired sound are suppressed by doing away with the torque pulsation or making the fluctuation band of the torque pulsation small.
