摘要： A swing angle measuring apparatus generates feedback signals for closed loop regulation of a load swinging motion in operation of a crane. The swing angle measuring apparatus measures two-dimensional swing angles, and includes a rope fixed to a hoisting device, two laser displacement sensors, laser reflecting plates, and a rectangular box attached to a hoisting device. Two steel reflecting plates are installed on the periphery of the fixed rope. Two laser displacement sensors are installed in a rectangular box such that the heading of the sensors are configured to perpendicularly intersect the faces of the laser reflecting plates. The configuration of the displacement sensors and the reflecting plates can be reversed. The rectangular box is attached to the hoisting device, and the laser reflecting plates are placed at an offset distance away from the face of the laser displacement sensors, at which a sensor signal of 0 volts is obtained. The swing angle of the rope or cable is determined from the distance between the laser displacement sensors and the laser reflecting plates.

摘要： The present invention relates to a radioactive electron emitting microchannel plate. More particularly, to a radioactive electron generating microchannel plate comprising (a) a pair of parallel substrates; (b) at least one radioactive material layer deposited on an inner surface of the substrates; and (c) at least one electron ray-amplifying layer deposited on the surface of the radioactive material layer. The emitted electron ray is amplified by penetrating into the cavity formed by a pair of parallel substrates and is further amplified by reflecting from the electron ray-amplifying layer. As the substrate in the microchannel plate, use can be made of a capillary tube or a thin plate. The microchannel plate of the present invention can be applied as an electron ray source in an electron ray-generating device, an image display device, and electron ray-etching device.

摘要： Disclosed is a fiber bundle contactor in which fibers are packed in high density within a column. When two liquid phases flowing in parallel, one of which contains the desired components, are contacted with the entryway of the highly packed fiber bundle, the two liquid phases are very thinly dispersed among gaps around the respective fibers by capillary action induced by the clearance between the fibers. By means of this capillary action, the two liquid phases are maintained as a continuous stream, and the two phases are brought into very intimate contact, thereby ensuring a very large surface area for liquid-liquid extraction to proceed.
