摘要： PROBLEM TO BE SOLVED: To suppress the influence on emission by discharge or to improve the withstand voltage characteristic to provide an image of stable quality by using a non-magnetizable material as a focusing electrode situated between an input part and an output part, and forming an insulating material layer on the surface. SOLUTION: A photoelectron emitted from an input part 13 is accelerated and focused to first to third focusing electrodes 14-16 and an anode 17, and incident on an output part 18. The first to third focusing electrodes 14-16 are formed of, for example, aluminum, and a black insulating film 20 is formed on the third focusing electrode 15 by alumite treatment. According to this structure, electric connection of cutting foreign matters or burrs left in the vicinity is prevented by the insulating film 20, so that no intermetal compound is formed, and fixation of the cutting foreign matters or burrs to the third electrode 16 is suppressed. Thus, the discharge or minute emission between the cutting foreign matter part on the surface or the tip part and the anode 17 is eliminated, and deterioration of a diagnostic image can be prevented.

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.

摘要： 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.
