摘要： An X-ray analysis apparatus has a charged particle beam generator (1,2), an X-ray generating target (3) bombarded by the beam and a detector (8) for X-rays from said target (3) transmitted by a test piece (6). To improve the spatial resolution of the apparatus, the beam size is reduced at the target by locating the target (3) outside a vacuum chamber of the beam generator (1,2) by providing the target (3) as a non-circular narrow track of X-ray generating material exposed at both surfaces of the target, and by providing the beam generator with a beam accelerator and means (2) for reducing the beam diameter between the beam accelerator and the target (3).

摘要： A system for discriminating radiation-contaminated fragements (1) on the basis of a predetermined radioactive concentration includes a detection device (7) for detecting the radiation of the fragments (1), the detection device (7) having a path (88) of transfer of the fragments (1), at least one radiation detector (2) disposed at one of the inside and outside of said transfer path (88), and a transfer device (83; 90; 98) for sequentially transferring the fragments (1) in the transfer path (88); a convey device (42) for conveying the fragments (1) to said detection device (7); and a controller (100) for determining the radioactive concentration of the fragments (1) in accordance with the radiation detected by the detection device (7) and for judging whether or not the radioactive concentration of the fragments (1) is the predetermined radioactive concentration. The controller (100) is also operable to control the transfer device (83; 90; 95; 98) so as to adjust the speed of transfer of the fragments (1) in the transfer path (88). The system further includes a density detecting device (39) for detecting the density of the fragments (1) to be conveyed to the detection device (7). The controller (100) corrects the above determined radioactive concentration by the density detected by the density detecting device (39).

摘要： A safety control safeguard system includes sensors (A₁, A₂, A₃, A₄) disposed in a quadruple array. First, second third and fourth signal processing channels (25A, 25B, 25C, 25D) provided in parallel each include signal processing means for receiving output signals from the associated sensors for producing a trip signal. First and second actuating means (16, 17) operable independent of each other are provided for actuating an apparatus to be controlled. A first switch means (5A) operatively connected to the first, second, third and fourth processing channels for activating the first actuating means in response to reception of the trip signal produced by the signal processing channels and second switch means (5B) operatively connected to the first, second, third and fourth processing channels for activating the second actuating means in response to reception of the trip signal produced by the signal processing channels. The first and second switching means are operable independent of each other and constitute a 2-out-of-4 logic circuit in cooperation with the first and second actuating means.
