    摘要: A DC or high frequency ion source comprising a hollow cathode and a substantially hollow anode for applying a DC or alternating voltage; a gas inlet disposed at a first side of the cathode for supplying a discharge gas into the cathode; a cathode heater disposed between the anode and the cathode; a magnet disposed adjacent the anode to thereby improve the uniformity of a plasma; an ion extraction outlet disposed at a second side of the cathode opposite to the gas inlet and having an elongated rectangular shape; and an ion extraction electrode and an acceleration electrode for controlling the energy of extracted ions. Both the anode and cathode comprise substantially hollow boxes. The cathode includes an elongated rectangular cross section and is disposed inside the substantially hollow anode. The ion extraction electrode and the acceleration electrode have an elongated rectangular shape and an opening coextensive with the ion extraction outlet. The ion extraction electrode and the acceleration electrode are disposed adjacent, and aligned with, the ion extraction outlet. The ion source can be formed with an arcuate shape to accommodate round objects. The ion source can also be formed integrally with a sputtering device.

    摘要: 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.

    摘要: 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.

    摘要: 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.

The locations of the evacuation ducts closest to the opposite ends of the casing are spaced apart from the ends of the casing by distances greater than the length of the container. The intervals between the locations of the evacuation ducts are preferably longer than the length of the container. There can also be provided a plurality of tunnel-like casings, the insides of which are evacuated by a single evacuation facility through the evacuation ducts.
