    Abstract: [Object] To provide a high-performance rare earth-based magnet exhibiting a high coercive force or a high residual magnetic flux density even when the content of a rare earth element such as Dy or the like which is scarce is reduced. [Construction] A rare earth-iron-boron based magnet includes a crystal grain boundary layer enriched in element M (M is at least one rare earth element selected from Pr, Dy, Tb, and Ho) by diffusion of the element M from the surface of the magnet, wherein the relation between the coercive force Hcj and the content of the element M in the whole of the magnet is represented by the following expression: Hcj≧1+0.2×M (wherein 0.05≦M≦10) wherein Hcj is the coercive force (unit: MA/m), and M is the content of the element M in the whole of the magnet (% by mass). Furthermore, the magnet satisfies the following expression: Br≧1.68−0.17×Hcj wherein Br is the residual magnetic flux density (unit: T).

    Abstract: A fuel injection control apparatus is capable of supplying a proper amount of fuel by improving response when the throttle position is abruptly changed. The fuel injection control apparatus includes an electronic control unit for determining a fuel injection time period for a fuel injection system, based on the engine speed and the throttle position. The electronic control unit is operable to determine a base fuel injection time period based on engine speed and throttle position to start fuel injection, and adjusts the initial fuel injection time period thereafter, based on changes in the engine speed and the throttle position.
