Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A road map display system comprises a map memory for storing map image data, a sensor for detecting the travelling distance and travelling direction and outputting a signal representative of the angular offset between the direction of travel and an axis of a map coordinate system, an arithmetic means for calculating the map coordinates of a point halfway between the vehicle position and the destination, a coordinate transforming means which transforms the map image data to a display coordinate system, the origin of which lies halfway between the vehicle and the destination and the y-axis of which lies parallel to the direction of travel, a display memory in which the map data and symbols representing the destination and the position and the direction of travel of the vehicle are stored in terms of the display coordinate system, and a display means displaying the information stored in the display memory on the display screen.

Abstract: A display of images on a screen which is installed in an automotive vehicle for displaying the driving direction and location of the automotive vehicle within a graphic pattern, such as a drive map, comprising: (a) a screen device; (b) a first memory unit in which data of a graphic pattern to be displayed on said screen device is stored; (c) a second memory unit in which at least one word and mark to be superimposed on the graphic pattern and those positional data on the graphic pattern are stored; (d) a signal generator which outputs a command signal to rotate the graphic pattern on said screen unit by an angle with respect to an original position; (e) a shift circuit which shifts the positions of all words and marks stored in said second memory unit to those rotated at the angle corresponding to the command signal from said signal generator; and (f) an image control unit which controls the display of graphic pattern rotated by the angle corresponding to the command signal from said signal generator on said

Abstract: 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.

Abstract: An electronic liquid level gauge for measuring the level of a liquid contained in a vessel by employing an electrode pair immersed in the liquid. The electrode pair is associated with an oscillator which generates pulses of a repetition period directly proportional to the electrostatic capacity of the electrode pair. A counter is provided which is reset by an oscillator pulse and starts counting reference pulses of a predetermined repetition rate with a predetermined time delay relative to the occurrence of the oscillator pulse.

Abstract: 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.

Abstract: 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.
