Abstract: The present invention provides a positioning method and layout that can be used to dispose robots efficiently in an automobile painting and sealing line. This invention relates to the positioning of robots in an automobile painting line in which a downflow circulatory system is established. The main body of a sealing robot is positioned in a location at which it does not cause a large disruption in the downflow circulation along the side of an automobile body, and a robot for painting the under-surface of the floor of the automobile body is provided therebelow. Sealing and painting of the under-surface are performed in parallel.

Abstract: A joint device enables to join a brace member, into which regulated pretension is exactly introduced, to unmovable connector nodes, comprising a steel rod 1 having a swelled portion 1A and a threaded connector portion 1B formed on the end thereof, respectively, one sleeve 3 providing an external threaded part 3A joined to one node 2M, which contacts a swelled portion 1A: and another sleeve 4 providing an external threaded part 4A joined to node 2N, which engages threaded connector portion 1B. The length from a node-contact face 3c of sleeve 3 to a node-contact face 4c of sleeve 4 is selected equal to difference of length between both nodes 2, 2 from length for generating a preferable elongation enough to introduce regulated pretension into steel rod 1.

Abstract: Apparatus and method for expediting the starting of an internal combustion engine in which a vacuum-operated throttle actuator is controlled by a vacuum passage connected therewith and extending from an intake vacuum outlet located adjacent to the throttle valve. According to the invention, a second vacuum passage to the actuator communicates with the intake duct downstream of the throttle valve and a solenoid type switching valve is arranged between the two vacuum passages so that, when a warmed engine is restarted, the actuator is fed with vacuum through the second passage to actuate the throttle valve to a more open position than its normal idling position to yield a mixture of optimal air fuel ratio.
