摘要： The invention relates to a valve structure which can be easily worked, does not increase a producing cost, can reduce a dispersion in a side gap by restricting an eccentricity and an incline of a valve body and can maintain an injection accuracy high. In particular, the invention relates to an electromagnetic fuel injection valve (1) which is advantageous in view of production even in a narrow valve structure. In the electromagnetic fuel injection valve (1), at least one guide portion having one end fixed to an injection valve main body and guiding an axial sliding motion of the valve member in the inner portion is provided, and a nozzle guide body (5) constituting a magnetic passage portion formed so as to surround a magnetic member connected and fixed to one end of the valve member by the same material is provided. Accordingly, it is possible to reduce a dispersion of a sidge gap constituting the magnetic passage, and it is possible to stabilize an axial motion of the valve member, whereby an injection accuracy is maintained high and an inexpensive injection valve is obtained.

摘要： The system (1) has a rear wheel actuator control unit (17), which controls a drive of a rear wheel side actuator in such a manner that opposing driving torques are produced on respective rear wheels based on a steering condition in a halting condition of a vehicle, in normal and backward conditions. The driving torque is produced on one of the wheels, when braking force is produced on the other wheel.

摘要： The invention relates to an electromagnetic fuel injection valve having a needle (5) equipped with a valve body, a return spring (7) for applying a spring load to a valve seat side of the needle (5), an electromagnetic coil (2), and a magnetic circuit for magnetically attracting the needle (5) in the opening direction of the valve by the excitation of the electromagnetic coil (2). The needle (5) has a movable core (14) operating as an element of said magnetic circuit. The movable core (14) and the valve body are connected via a joint having a spring function. A plate spring (50) is built into the needle (5), and an axially movable mass body is positioned, independently of the needle (5), between the return spring (7) and the plate spring (50).

摘要： A system for detecting a physical amount of behavior of a vehicle includes, acceleration sensors arranged on at least two longitudinal axes of the vehicle, the vertical axis Of the vehicle and the lateral axis of the vehicle, a plurality of the acceleration sensors being disposed on each of the axes. A unit is provided for establishing a conversion equation for determining acceleration values of linear motion at an arbitrary point of the vehicle in the direction of each axis of an arbitrary coordinate system and acceleration values of rotational motion with respect to the each axis of the coordinate system while simultaneously using acceleration values detected by the acceleration sensors disposed on at least two of the vehicular longitudinal axes, the vertical axis and the lateral axis. There is also provided a unit for calculating the conversion equation to obtain the acceleration values of linear motion at an arbitrary point of the vehicle in the direction of each axis of the arbitrary coordinate system and acceleration values of rotational motion with respect to each axis of the coordinate system, a unit for establishing a motion equation expressing a plurality of freedom motions, and a unit for calculating the motion equation with the acceleration values of linear motion at an arbitrary point of the vehicle in the direction of each axis of the arbitrary axis of the arbitrary coordinate system and acceleration values of rotational motion with respect to the each axis of the coordinate system to obtain the physical amount associated with the behavior of the vehicle.
