Abstract: An on-vehicle data processing system is provided which can cause the vehicle information to be displayed on a display device 10. The on-vehicle data processing system has a mode setting unit 32 for setting the running and stop modes and a data processing unit 34 for computing the mode images. The data processing unit 34 computes the running mode images representing the running states of the vehicle in real time while in the running mode and the stop mode images representing the details of the vehicle information while in the stop mode. Thus, the running mode images, more easily viewed by the driver, can be displayed on the display device in the running mode while the stop mode images, preferentially displaying the contents of the vehicle information, can be displayed on the display device in the stop mode.

Abstract: A solenoid valve used in a brake fluid circuit of an anti-lock braking system of an automotive vehicle. The solenoid valve comprises a plunger which is axially movable upon energizing and de-energizing of an armature core located inside a solenoid coil. The plunger is formed of a sintered metal and formed at its tip end with a fitting groove. A spherical metal valve member is fixedly fitted in the fitting groove by caulking an outer peripheral wall surrounding the fitting groove. The valve member is brought into contact with a valve seat member formed with an oil passage through which oil is flowable, upon movement of the plunger toward the valve seat member.
