    Abstract: A lowering collision avoidance device includes a container detector, a rope winding speed detector, a rangefinder for detecting the distance to an adjacent container, a rope length detector, and a controller which controls a hoisting/lowering drive motor, thereby controlling the lowering speed, in such a manner that when the container detector becomes ON, a lowering stop action is performed to start decreasing the lowering speed at a predetermined rate; even during this period, the remaining lowering distance and a normal stopping distance are computed; and when the container detector becomes OFF for one period of swing computed from the rope length detected by the rope length detector, and after a judgment is made that the risk of collision of a lowered container with the adjacent container has vanished, lowering is resumed if the remaining lowering distance is larger than the normal stopping distance, or an emergency stop action is performed if the remaining lowering distance is not larger than the normal stopping distance. Thus, the container can be lowered rapidly to a place where obstacles such as containers stacked in layers are located, with the collision of the container with the obstacle being prevented.

    Abstract: A sputtering apparatus including two electrodes, a sputtering target disposed on one of the electrodes, and a gas supply for supplying a discharge gas in a vacuum to produce an electric discharge between the two electrodes and whereby particles sputtered from the target due to impact thereon of ions produced by the discharge, are deposited on a substrate. The target disposed on one electrode is formed into an elongated band and the other electrode is disposed so as to enclose the target. The other electrode is also provided with a magnet for producing a magnetic field thereon, and further includes a narrow elongated slot which defines a narrow sputter particle outlet. The narrow sputter particle outlet permits a pressure to exist near the electrical discharge which is higher than the pressure near the substrate. According to a preferred embodiment, the sputtering apparatus has an ion source combined integrally therewith.

    Abstract: A lowering collision avoidance device includes a hoisting accessory swing detector, a rope winding speed detector, an arithmetic unit, a rope winding speed controller, and if desired, a rope length detector. The arithmetic unit computes a command value for the lowering speed based on the results of comparison between the amount of swing of a hoisting accessory detected by the hoisting accessory swing detector and a predetermined threshold level or a plurality of predetermined threshold levels; the direction of changes in the amount of swing computed based on the amount of swing of the hoisting accessory; and the lowering speed detected by the rope winding speed detector. The rope winding speed controller controls the lowering speed based on this command value. The arithmetic unit also predicts maximum displacement by swing based on the amount of swing of the hoisting accessory, the positional change rate of the hoisting accessory computed based on this amount of swing, and the period of vibration of the hoisting accessory computed from the rope length detected by the rope length detector, and computes a command value for the lowering speed based on the results of comparison between the maximum displacement and a predetermined threshold level. The rope winding speed controller controls the lowering speed based on this command value as well.

    Abstract: A handwriting storing and reproducing method which takes small images including a leading edge for writing and stores the small images in a time sequential manner following a movement of a writing device. The method then reads out the stored small images and overlaps a just read out small image to a previously read out small image so as to obatain a partial image when both small images include portions which include partial handwritings coincident to one another. Thereafter, the method overlaps one partial image to another partial image-so as to obtain a larger image when both partial images include portions which include partial handwritings coincident to one another.

    Abstract: A control system for an AC excited synchronous machine for use in an electricity generator/motor system. The AC excited synchronous machine can be driven not only in a variable-speed operation based on 2-axis current control but also in a constant exciting frequency operation based on only direct-axis current component control. A phase signal is switched to drive stably the AC excited synchronoius machine in a self-excited operation or in a rotary phase modifying operation. Further, when it is desired to start pumping-up water, a synchronizing power is provided to keep constant the rotational speed of the machine at the time of establishing a desired water pressure. Because of the switching arrangement of the phase signal, the AC excited synchronous machine can be operated as an ordinary synchronous machine exhibiting ordinary synchronous characteristics, that is, self-excited operation characteristics, rotary phase modifying operation characteristics and pumping-up start characteristics. Even when the synchronous machine is cutoff from an AC power system and the voltage of the synchronous machine is abruptly changed, the stable self-excited operation of the machine can be realized.
