    • PROBLEM TO BE SOLVED: To provide an inexpensive electronic water meter by eliminating metering errors and reducing the current consumption of the meter.
      SOLUTION: The electronic water meter is constituted in such a way that a magnetic sensor section 22 sends an electromagnetic induction pulse 22 obtained from the rotation of a permanent magnet 21 and a pulse shaping section 23 sends a rectangular-wave signal 23w by shaping the pulse 22p, a normal/reverse discriminating section 24 sends a normal/reverse rotation signal 24s based on the signal 23w, and a reversible counting section 25 finds an integrated value by counting counting pulses based on the signal 24s. In addition, a displaying section 26 displays the integrated value and a main control section 27 calculates the used amount of water from the integrated value. Moreover, a communication section 28 transmits and receives signals from and to the outside and an electromotive force generating section 29 generates a voltage and supplies the voltage to the section 23, 24, 25, 26, 27, and 28. Furthermore, an electricity storing section 30 stores electric charges from the electromotive force generating section 29 and a battery section 31 supplies a voltage to the sections 23, 24, and 25 when no voltage is supplied from the sections 29 and 30.

    • PROBLEM TO BE SOLVED: To suppress a seizure of a X-ray image tube output part by a method wherein the X-ray image tube is rotated around the axis of an electron lens. SOLUTION: A vacuum enclosure 12 constituting an X-ray image tube can be rotated independently against a TV camera 20 around the axis of an electron lens formed by grid electrodes 15, 16 or an anode 17. For example, to the rear end part of the X-ray image tube is fixed with adhesive agent a supporting mechanism 21 for a circular gear-like stainless steel ring mounted in a coaxial manner in respect to an axis of the tube and in parallel with an outer surface of an output window 18. A rotating drive mechanism 22 for an electric motor having a high torque capable of rotating a bulb is arranged to be electrically connected to have a ground connection with the gear-like supporting mechanism 21 or mechanically connected under a mechanical connection so as to enable its cooperative operation to be carried out in such a way that the narrowed and fine rear end in the vacuum enclosure 12 may be enclosed. As required, a rotational speed of the X-ray image tube is changed and further the X-ray image tube is rotated in two-way directions opposite to its former direction.

    • PURPOSE:To provide an X-ray image tube having improve resolution to improve image quality. CONSTITUTION:An X-ray image tube 1 has a vacuum enclosure 2, and an input window 3 is installed on the input side of the vacuum enclosure 2 to be in pressure-contact with a metal holding ring 4. The metal holding ring 4 is installed on a covar ring 5 by welding. Thickness of the input window 3 is set to be 0.2% or more and 0.4% or less of an effective view field, and an input fluorescent surface 6 is formed on the inner surface side of the input window 3. Focusing electrodes 11, 12, a positive electrode 13, and an output phosphor body 15 are provided on side walls inside the vacuum enclosure 2, and an output window 14 is formed on the output side. A radial ray source 21 is disposed facing the input window 3 of the X-ray image tube 1, and a sample 22 is disposed between the X-ray image tube 1 and the radial ray source 21. A TV camera 23 is disposed facing the output window 14 of the output phosphor body 15. When a ratio of the thickness to the effective view field is 0.2% or more and 0.4% or less, a transmission ratio is improved sufficiently, compared to that of more than 0.4%. The input window 3 is crushed by an atmospheric pressure when the ratio is less than 0.2%.

    • PURPOSE:To provide an X-ray image tube in which deformation of an input window is prevented, and in which a correct image can be obtained even where an input phosphor layer and a photoelectric surface are provided to be tightly applied on the input window for improving contrast. CONSTITUTION:In an X-ray image tube 1, a metal holding ring 3a is pressure-welded around an input window 3 of a glass tube 2, and the metal holding ring 3a is welded with a KOV ring 4 to compose a vacuum enclosure 5. On the outermost circumference of the input window 3, a vertically and sharply standing shock absorbing part 3b is formed, and the metal holding ring 3a is pressure-welded and jointed. On the other end side of the glass tube 2, an output window 6 is formed, and an output screen 7 is formed inside the output window 6. An input phosphor layer 8b of cesium iodide including activator, and a photoelectric surface 8c are formed at a part of an effective view field of the shock absorbing part 3b of the input window 3. A focusing electrode 9 and a positive electrode 10 are disposed between the photoelectric surface 8c and the output screen 7. A lot of effects are not given to the effective view field on the inner side of the shock absorbing part 3b even when the shock absorbing part 3b is deformed at the time of jointing, thereby a correct image can be provided.
