摘要： Disclosed is an information and electrical power transmission system. In this system, when required, i.e., when an ignition keyswitch is in an ON state, a plurality of information and electrical power are transmitted from an electrical power supply side to an electrical power receiving side through a signal line, and, at the same time, a plurality of information can be transmitted through the signal line from the electrical power receiving side to the electrical power supply side. When the ignition keyswitch is in an OFF state, information which is required to be always transmitted can be transmitted with a low power consumption, so that the information and electrical power necessary for a vehicle are suitably transmitted.

摘要： An apparatus for displaying the driving direction and distance coverage of a motor vehicle, wherein a unit distance coverage signal is generated each time the motor vehicle covers a unit distance, a direction signal indicating the present driving direction of the motor vehicle is generated, and the distance and the direction from a starting point to a destination point can be set and the resulting setting signals are generated. The distance coverage for each driving direction of the motor vehicle is accumulated on the basis of the unit distance coverage signals and the direction signals, and from the accumulated values the vector from the starting point to the present position is calculated. The calculated vector and the vector from the starting point to the destination point which is obtained from the setting signals are used to calculate the vector from the present position to the destination. The present driving direction of the motor vehicle is indicated on a first display section in response to the direction signal, and the direction and the distance of the vector from the present position to the destination are displayed on a second display section on the same display panel on which the first display section is provided.

摘要： A brake oil pressure control device including a main line system for a normal braking operation, and a subline system for antiskid control and acceleration slip control. The main line system connects a master cylinder to a wheel cylinder, and has a first valve which opens the main line for a normal braking operation, and closes the main line when an antiskid control or acceleration slip control is in effect. The subline system has an oil pump connected to the wheel cylinder through a subline having a second valve, which is controlled to open and close the subline for the antiskid control or acceleration slip control. Inlet and outlet ports are connected by a relief pipe having a third valve and a relief valve. The relief valve opens the relief pipe under pressure from the master cylinder when a discharge pressure from the oil pump is higher than the pressure at the master cylinder, to restrain the discharge pressure from the oil pump. The third valve opens the relief pipe for an antiskid control, and closes the relief pipe for an acceleration slip control.

摘要： Disclosed is an anti-skid control system incorporated in the hydraulic pressure braking apparatus of a motor vehicle including a wheel braking cylinder responsive to a hydraulic pressure developed by a master cylinder for braking a wheel of the vehicle. The anti-skid control system comprises a hydraulic pressure supplying device and a directional control valve provided between the wheel braking cylinder and the hydraulic pressure supplying device. The directional control valve is actuated to shut off the communication therebetween and the actuation thereof is controlled in accordance with a duty cycle, which is in turn updated in accordance with the difference between a wheel speed and a target wheel speed so that the slip ratio of the wheel becomes equal to a target slip ratio.

摘要： PURPOSE:To automate a return to the initial state during supplying of air by forming a wire pressure detecting device by a movable member having a magnetic material capable of moving by centrifugal force or vibration, a means for switching the movable member to a locked or loosened state, and means for detecting magnetic flux of the magnetic material to judge whether the magnetic flux is regular or irregular. CONSTITUTION:Air pressure in an internal air chamber 49 is increased or decreased by the tire internal pressure to expand or contrast a bellows part 51 to lock or loosen a magnet-presser part 53 and a cap 57 to/from a spherical magnet 55. When the spherical magnet 55 is loosened due to the tire pressure drop, it is moved at random by centrifugal force or vibration. A magnetism detecting unit 31 detects the movement of the magnet to judge the tire pressure drop. On the one hand, when air is injected, the spherical magnet 55 is locked to any position by the magnet-presser 53 and the cap 57. Thus, signals detected by the magnetism detecting unit 31 are stabilized during travelling so that it is judged whether the air pressure is normal or not. As a result, a return to the initial state is automated.
