A road map displaying system for an automotive vehicle for displaying road information transmitted by a radio beacon transmitter (1) on a display unit (6) of an automotive vehicle comprises: a radio receiver (3) for receiving road information including position data and traffic snarl data transmitted by the radio beacon transmitter; a memory unit (4) for storing various road maps; and a processing unit (5) for selecting a current road map on the basis of the received position data, displaying traffic snarl information on the selected road map on the basis of the received traffic snarl data, measuring time elapsed after the road information has been received, and in particular, deleting the traffic snarl information displayed on the selected road map, when a predetermined timer or distance-related condition is satisfied after the road information has been received. Since the old traffic snarl information can be deleted, a more reliable traffic information can be provided to the driver, without confusing the driver with the old road information.

A plane antenna comprising first and second plates made of a synthetic resin. The first plate has a first metal film formed thereon and the second plate has a second metal film formed thereon. A plurality of pins extend between the first and second plates for maintaining the first and second plates in spaced-parallel relation to each other with the first and second films facing to each other. The pins include at least one first pin for providing an electric connection between the first and second metal films and a second pin insulated from the second metal film for providing an electric connection of the first metal film to a lead wire. The first and second metal films have a spacific resistance .rho. [m] and a permeability .mu. [H/m]. The first and second metal films have a thickness greater than a value t [m] calculated from an equation as follows: ##EQU1## where f is a signal frequency [Hz] for which the plane antenna is used.

In a production supervising system of a work, a wireless type production supervising data processing apparatus is mounted on the work. The wireless type production supervising data processing apparatus includes a wireless type interface unit, and an IC card. The IC card includes CPU, EEPROM for storing the production supervising data, ROM for storing the program data, and RAM capable of storing other data than the production supervising data. The wireless type interface unit includes antennas, a receiver, a transmitter, a demodulator connected to the receiver, and a modulator connected to the transmitter. During the production of the work, the production supervising data previously stored in EEPROM are read from the IC card and processed in the interface unit and thereafter transmitted from the interface unit toward the external data controlling apparatus.

A road map display system for an automotive vehicle displays a mark representative of a vehicle's position and direction. The mark is positioned at the center of a display screen and the coordinate system of the map is transformed depending on the vehicle's direction so that the mark indicative of the direction is always directed upward along the y-axis of the display. The system further includes a scale selector which is manually operable. Depending on the selected map scale, the displayed map is magnified or reduced.

An automatic seat positioning device for a vehicle driver's seat wherein a reversible motor is engaged with one of electromagnetic clutches and rotates so that an associated seat member actuating mechanism moves one of the seat members to a desired position for a specific driver from an initial position upto a maximum movable end. In such an automatic seat positioning device of the construction described above, a seat position detector corresponding to the seat member for detecting that the seat member arrives at a specific position at which the detector is located and a preset control circuit for presetting a counter, which indicates the set position of the seat member by counting the number of rotations of the motor, to a value corresponding to the number of rotations of the motor by which the seat member is moved from an initial starting position to the specific position are provided so that an indication error of the counter can be canceled due to slips which occur whenever the motor is repetitively started and stopped, engaged with the electromagnetic clutch. In addition, the automatic seat positioning device stores the positional data of the seat member set at the desired position from the counted value of the counter in a memory provided therewithin in order to return the current set position of the seat member to an originally set position on a basis of the stored data. In this case, a memory correction circuit is provided which corrects an erroneous stored data to an accurate value corresponding to the actual position in response to the presetting of the counter according to the number of times by which a manual switch which energizes the motor in a normal or reverse direction is operated. Therefore, the seat member can more accurately be returned to the originally set position.

A navigation instrument comprises a first counter for counting travelling distance from a start point, a second counter for counting travelling time from starting, a means for setting a scheduled average vehicle speed, an arithmetic means for calculating average vehicle speed, the deviation of travelling distance from the scheduled distance and the deviation of travelling time from the scheduled time, and a display means for displaying the result of calculation. The first counter is capable of subtractively counting travelling distance in response to switching operation of a switching means which is incorporated to the first counter. The first counter is also incorporated with a means for stopping navigating operation which is operative when the first counter counts down the travelling distance until a given value.

Navigation instrument

A navigation instrument for use with a roadway vehicle comprises an arithmetic means producing three data signals showing the average speed of the vehicle, the deviation of the travelling distance from a scheduled one, and the deviation of the travelling time from a scheduled one, and a display means for displaying the three data sequentially fed from the arithmetic means through a signal selector means. The arithmetic means includes travelling distance/time deviation accumulating means for adding the deviation of the travelling distance/time with respect to the average speed initially set to the deviations of the travelling distance/time whenever the average speed is altered. Thus, the navigation instrument of the present invention makes it possible to calculate and display the travelling distance/time deviation accumulated value when the average speed of the vehicle is altered on the way of vehicle travelling.
