Abstract: A palletizing method for articles by a robot wherein a final stacking pallet is moved as a hand portion of the robot moves, and when an article is loaded on the pallet, the final stacking pallet is made to assume a position in the neighborhood of a position where the article is gripped up by the robot hand to transfer the article.

Abstract: A robot system for encasing conical articles, having along a moving path of a robot a conical article arraying and feeding device, an empty case for enclosing therein said conical articles and an inverting device for carrying and inverting a plurality of said conical articles, the robot having two kinds of grippers, one functioning to grip and convey the conical articles arranged on the arraying and feeding device and the other functioning to grip and convey the conical articles inverted on the inverting device.

Abstract: The transportable robot system comprising a plurality of robot working areas, an unmanned transporter for transporting a robot mounted thereon and moving between the robot working areas and a travel track for the unmanned transporter to provide a communication between the areas. The unmanned transporter provides a base to which to robot is mounted and secured, and a locating station for the base is provided near a machine tool in the working area so that the base may be put on the locating station at a predetermined position.

Abstract: An alternating current limiting apparatus is disclosed which normally forms first and second series circuits connected in parallel with each other between different kinds of power system lines. The first series circuit is resonated with a reactor and a capacitor at a line frequency to directly interconnect the power system lines. The second series circuit is composed of a capacitor or a reactor and two resistors. Between the interconnection of the reactor and the capacitor of the first series circuit and the interconnection of both resistors, a closing device is connected. Upon the occurrence of a fault of either of the power systems, the closing device is thereby actuated to form a parallel resonance circuit with the combination of the reactor or capacitor of the first series circuit and the capacitor or reactor of the second series circuit to limit current flowing between the power system lines.

Abstract: An record medium bearing toner images is intermittently moved at different speeds toward a fixing unit including a flash lamp. Each time one portion of the record medium occupies the effective fixing section of its run for the lamp as determined by a sensor device, the flash lamp is lighted to fix the toner images on that portion of the record medium. This fixing is repeated with the succeeding portions of the record medium until all the toner images on the record medium are successively and continuously fixed.
