Abstract: An apparatus for adjusting the position and/or angle of each movable equipment of a motor vehicle comprises sensors to produce electrical signals indicative of the position and/or angle of each movable equipment, memory circuit including a plurality of memory units for respectively storing sensed information indicative of the optimal positions and/or angles of the equipment for each driver, comparators responsive to the sensed information and the stored information, and driving circuitry responsive to output signals of the comparators to adjust the positions and/or angles of the equipment. When the drivers are changed, the sensed information is compared with the stored information and then the position and/or angle of each equipment is adjusted until the sensed information equals the stored information to provide the driver with the optimal position and/or angle.

Abstract: An electronic trip meter for an automotive vehicle comprises an up-down counter, a memory circuit, an adder-subtractor, a display circuit, and other auxiliary circuits. The up-down counter produces a signal indicative of a remaining distance to a goal by subtracting an actually travelled distance from a preset distance between two points for displaying the remaining distance by the display circuit. When the vehicle reaches the goal, the adder-subtractor produces a signal indicative of the actually travelled distance in accordance with the output signals of the up-down counter and the memory circuit in which the preset distance is stored. The adder-subtractor output signal is then fed to the up-down counter for displaying the actual distance between the two points and to the memory circuit for correcting the preset distance whereby a remaining distance to the starting point in a return trip is easily and accurately obtained. The trip meter may be also utilized for a trip beyond the goal.

Abstract: An item selection signal input system comprising a keyboard panel including a plurality of matrix aligned, transparent touch sensitive switches. An item list setting mechanism is provided for placing a desired item list below the keyboard panel in order to mark each of the touch sensitive switches. The item list setting mechanism comprises an item list carrying drum to which one end of a plurality of item lists are fixed. The desired item list is selected while the item list carrying drum is driven to rotate.

Abstract: An electronic trip meter for a motor vehicle comprises an up-down counter, a memory circuit, display circuit, and other auxiliary circuits. The up-down counter produces an output signal indicative of a distance travelled by the vehicle by counting a number of pulses generated each time the vehicle travels a predetermined distance or a distance remaining to an objective point of a predetermined course by subtracting the travelled distance from a preset distance. The counting up and down functions of the up-down counter is manually controlled for compensating for a travelled distance along a wrong course. The output of the up-down counter is fed to the display circuit for displaying a distance indicated by the output signal thereof. A plurality of distances of legs of a predetermined course may be stored in the memory circuit so that each distance is fed to the up-down counter as the predetermined distance.

Abstract: An electronic trip meter with a correction circuit for an automotive vehicle comprises a counter for producing an ouput signal indicative of a measured distance, an error detector for deriving an error factor of the measured distance with respect to a reference distance, a correction circuit for correcting the measured distance by the error factor, and a display circuit for displaying the corrected distance.

Abstract: An electronic trip meter with an alarm for an automotive vehicle comprises a travelled distance sensing circuit, a memory circuit, a modification circuit, comparators, an alarm, first and second counters, a subtractor, a display circuit, and other auxiliary circuits. A plurality of sub distances defined by guide points along a course and a total distance of the course are respectively preset in the memory circuit and the second counter. The second counter output signal indicates a distance remaining to the goal of the course for displaying the remaining distance. The modification circuit output signal indicates a distance shorter than a sub distance while the first counter output signal indicates a distance actually travelled. When the vehicle travells over the distance shorter than the sub distance, the alarm is energized, by means of a comparison of the distances for informing the driver that a next guide point is near.

Abstract: A navigational information indicator for supplying a vehicle driver with make-turn instructions comprises a first memory for storing each information indicative of each distance travelled by the vehicle as far as a point at which a turn is made, a second memory for storing each information indicative of the direction of each turn, and a display circuit for displaying a directional sign. When the vehicle travels from a first point toward a second point, the distances and directions of turns are respectively stored in the first and second memories in a sequence and these pieces of information are read out in the reverse sequence when the vehicle travels back to the first point from the second point along the same route. The stored information is read out to display each directional sign so as to supply the vehicle driver with make-turn instructions along the return trip.

Abstract: A speed alarm system for a motor vehicle comprises a speed sensor, a plurality of comparators responsive to the vehicle speed and respective preset reference speeds, and a plurality of lamps responsive to the output signals of the comparators. The threshold values which are defined by said reference speeds, are stepwisely arranged to change the number of the lamps energized. The number of energized lamps varies in accordance with the difference between the vehicle speed and a reference speed.

Abstract: A navigation instrument for roadway vehicles comprises a first counter for counting pulses each occurring in response to the vehicle moving a predetermined distance to detect the distance travelled from the starting point of a trip, a second counter for counting clock pulses to detect the time elapsed from the start of the vehicle. A microcomputer or digital circuitry is provided to compute on the data received from the first and second counters to derive an output data representative of the average speed of the vehicle over the distance so far travelled and to compare the computed average speed with a desired speed to detect the deviation of the actual average speed from the reference. A comparator is provided to detect when this deviation exceeds a predetermined value to generate a warning signal to alert the vehicle driver to correct the vehicle speed.

Abstract: A sheet material is initially formed into a flat and quadrilateral bag, the four sides of which are sealed. Each of the front and back sheets of the flat bag is pinched up and folded in two parts at each corner region along a line running through a point placed at a selected distance from the corner such that two imaginary and symmetrical lines drawn on the inner surface of the sheet meeting at this point and terminating respectively at the two adjacent sides of the corner region are overlapped each other, and then a joint is formed in the folded region of the sheet along the overlapped lines.

Abstract: The device for providing electric connection between a rotatable member and a stationary member has a doughnut-like housing of an insulating material and an annular and insulating base plate disposed in the housing coaxially and movably both in the circumferential and axial directions. Two annular contact plates are placed on a front face of the base plate, and two contact pins are held in the housing and urged always to stand on the contact plates, respectively, by means of compression springs. Both the housing and the base plate are locally shaped such that one of them can be fixed to the rotational member while the other can be engaged with the stationary member so as to be restrained from rotating together with the former.
