Abstract: An apparatus for testing an anti-lock brake system has rolls and device for detecting rotational changes of the rolls. The test is performed by running a vehicle having mounted thereon the anti-lock brake system while wheels of the vehicle are placed on the rolls, actuating the anti-lock brake system when a predetermined speed has been attained, and judging operating conditions of the anti-lock brake system from rotational changes of the rolls at the time of braking. In the apparatus, the friction coefficient of each of the rolls is set to such a value that a frictional force to act between each of the rolls and each of the wheels at the time of braking exceeds an inertia force of each of the rolls.

Abstract: A running control function of a motorcar is inspected on an inspecting apparatus which is provided with rolls for mounting thereon each of wheels of the motorcar. The control function operates to control rotational speeds of wheels depending on a difference in rotational speed between front and rear wheels or right and left wheels of the motorcar. The motorcar is caused to run in a condition in which each of the wheels of the motorcar is mounted on each of the rolls. When a rotational speed of a first roll for mounting thereon one of front and rear wheels or one of right and left wheels and a rotational speed of a second roll for mounting thereon the other of the front and rear wheels or the other of the right and left wheels have both increased to a predetermined speed, the first roll is decelerated.

Abstract: An apparatus for securely fastening a boot to a driving shaft in which a boot is fitted over each of both ends of driving shaft so as to cover an open end of a joint attached to each end of the shaft, and a band is wound around each of both ends of the boot by a band winding device so as to fasten both ends of the boot securely to the shaft body and the joint respectively, the apparatus comprising an assembly line along which the driving shaft is conveyed; a conveying jig movable along the assembly line, conveying jig having clampers for clamping a shank portion of each of the joints and the shaft body; the assembly line having a plurality of assembly stations, each of the assembly stations having at least one band winding device for winding a band around each of the predetermined end portions of the boot, and a positioning device for positioning the conveying jig at the assembly station; a loader device for setting the driving shaft on the conveying jig standing in a charging station located at a starting en

Abstract: An apparatus for fastening parts securely in place by a band having a band winding device for winding a band around each of tight-binding portions of plurality of parts fitted over an article to which the parts are to be fastened and a laser beam irradiation head applying a laser beam to the overlapped portion of both ends of the band, the apparatus comprising a plurality of working stations to which the article is conveyed successively, means for successively conveying the article through the plurality of working stations, a band winding device provided at each of the working stations, the band winding device being applicable to the corresponding predetermined tight-binding portions of the parts, a laser beam irradiation head provided for each of two groups of the band winding devices disposed in the plurality of working stations, one of which groups comprises those disposed in front along the conveying direction in which the article is conveyed and the other of which groups comprises those in the rear, each

Abstract: A robot apparatus is operable in a Cartesian coordinate system for moving a workpiece gripped by a hand thereof. The robot apparatus includes a self-propelled X-axis slide unit movably mounted on an X-axis rail unit extending in the direction of the X-axis of the Cartesian coordinate system. A Y-axis slide unit extending in the Y-axis direction normal to the X-axis direction has one end fixed to the X-axis slide unit. A self-propelled Z-axis slide unit is movably mounted on the Y-axis slide unit, and a slide base to which the robot hand is attached is mounted on the Z-axis slide unit. Lead wires connected to drive mechanisms for driving the X-axis slide unit, the Y-axis slide unit, and the Z-axis slide unit pass through case members, and are housed in the X-axis rail unit and connected to a terminal box secured to an end of the X-axis rail unit.
