    摘要: The present invention relates to a method and an apparatus for mounting a part at a specific position, particularly a chip part onto a substrate such as a printed circuit board, wherein a movable mounting head unit having at least one attracting nozzle unit picks up at least one part from a part supply unit, transfers the part and places same in a detection area of an optical detecting means at a recognition height, said optical detecting means emits parallel light beams for detecting a projected width of the part, the parts are subjected to a recognition process wherein projected width data are obtained under rotation of the part, and the part is mounted at the desired position. In order to determine a recognition height suited for each part quickly and with good accuracy, the method is improved in that optimum recognition height of each part attracted by said nozzle unit is determined by detecting a recognition height range with a projected width of the part that is more than or equal to the reference value and calculating a specified position within said recognition height range as the optimum recognition height of the part. The apparatus is improved in that a determination means is provided for determining whether the projected width of said part is more than or equal to reference value, and in that an operation means is provided for determining a recognition height range in response to an output of the determination means and for calculating a specified position within the recognition height range.

    摘要: An automatic electronic parts-mounting apparatus for mounting chip-like electronic parts having been supplied from a parts feeder at predetermined positions on a printed substrate. For accurately and quickly determining angular positions of the electronic parts by rotating adsorptive nozzles, the adsorptive nozzle being capable of adsorbing the electronic parts one by one is connected to a rotor of a nozzle-rotating motor for rotating the adsorptive nozzle within a plane being perpendicular to an axis of the adsorptive nozzle, and the rotor is rotated in accordance with the adsorbed state of the electronic parts to make fine adjustment for determining the angular position.

    摘要: Lorsque l'on effectue le service d'un moteur (10), il arrive fréquemment de devoir changer une chemise de cylindre (12) et un piston (18). Il est difficile, et cette opération prend du temps, d'installer tout d'abord la chemise (12), puis le piston (18) avec les segments (20) et la bielle (22). Une unité prémontée (36) comportant la chemise (12) et le piston (18) peut être installée sur le moteur selon un procédé décrit. Le montage unitaire simplifie les opérations à l'installation de service et, si on le désire, permet l'assemblage de l'unité (36) avant son expédition à l'installation de service afin de réduire l'encombrement et les coûts d'expédition.
