Abstract: The invention provides a novel apparatus for manufacturing electronic parts each incorporating a plurality of lead wires fully wrapped with conductive foil like noise filters for example. A turn table is intermittently shifted from the first work station to the seventh work station in the state in which an individual-unit lead-wire member is retained by a holding unit on the turn table. A predetermined lead wire is folded by respective work stations, whereas the remaining lead wires are adhered with conductive foil tapes via spot-welding process, and then these lead wires are fully wrapped with conductive foil tapes. Next, the predetermined lead wire is restored to the initial posture, and then all the lead wires are fully wrapped with insulation tapes. In this way, all the lead wires are properly processed so that they can be integrated in perfect alignment with constant pitches.

Abstract: The invention relates to a cooling apparatus for hot bulk material, such as sintered ore. Gaps are defined between respective lower ends of side wall portions of a moveable annular air duct and respective upper ends of side wall portions of a stationary annular air duct, which gaps communicate the air passage in the stationary annular air duct with annular water seal chambers. First seal plates are disposed at respective upper ends of the side wall portions of the stationary annular air duct in relation to respective lower ends of the side wall portions of the moveable annular air duct. Second seal plates are disposed at respective lower ends of the side wall portions of the movable annular air duct. Labyrinth seals are formed by the first seal plates, the side wall portions of the moveable annular air duct, and the second seal plates in combination. This seal arrangement is entirely different from the conventional seal structure which involves sliding contact of seal members with other surfaces.

Abstract: The present invention provides an apparatus to prevent the entrance of aquatic species into the intake watercourse having a U-shaped cross section with a narrow bottom and a wide surface, in which oppositely facing electrodes are installed vertically along the side walls on both sides of the intake watercourse, and the distance between the upper ends of the electrodes is made greater than the distance between the lower ends of the electrodes, and a voltage is impressed between the both electrodes. Since the electric barrier intensity is smallest at the surface of water and becomes greater as it goes toward the bottom of water, the river fish moving around the bottom of water make a U-turn when they reach the strong electric barrier, or alternatively, after reaching the strong electric barrier, they move upward to where the electric barrier is weaker and then make a U-turn, thereby the entrance of aquatic species into the intake watercourse can be prevented.
