  • Publication number: 20190021157
    Abstract: An X-ray imaging apparatus operates by selecting an appropriate exposure sensitivity corresponding to the X-ray detector to be used. In the apparatus, an exposure sensitivity corresponding to the flat panel detectors used for an X-ray imaging is selected from multiple exposure sensitivities stored in an exposure sensitivity memory unit of the console, and the selected exposure sensitivity is displayed on the display unit of the high-voltage unit. An exposure control is executed based on the exposure sensitivity corresponding to the flat panel detectors used for the X-ray imaging, which is selected from multiple exposure sensitivities stored in an exposure sensitivity memory unit. The exposure control unit of the high-voltage unit suspends the X-ray irradiation from the X-ray tube when an integrated value of the X-ray detected by the X-ray dose sensor reaches to the setting-value set relative to the selected exposure sensitivity.

  • Patent number: 9884229
    Abstract: The present invention provides, as a material for a golf club face of a driver, an iron or the like, a titanium alloy which satisfies the regulation for a coefficient of restitution, and has high Young's modulus and tensile strength and also has excellent hot and cold workability. The titanium alloy for a golf club face according to the present invention comprises, in percent by mass, 1.0 to 3.5% of Al, 0.5 to 1.4% of Fe, 0.2 to 0.5% or O and 0.002 to 0.030% of N, and the balance of Ti with inevitable impurities, wherein an ?-phase is strengthened by combined addition of O and Al, and inexpensive Fe is selected as a ?-phase stabilizing element, leading to high strength and high Young's modulus in combination. The content of Al causing deterioration of hot workability is limited to a low value, leading to low rolling load during hot rolling, and thus flaws and edge cracking are unlikely to occur during hot rolling.

  • Publication number: 20180000436
    Abstract: A radiography apparatus is provided in which delays in it do not occur due to the influence of preliminary preparation of a radiation detector. The FPD 4 receives a signal from an X-ray tube control unit 6 and then completes preliminary preparation for the detection of radiation during accelerated movement of an X-ray tube 3 or the FPD 4. That is, the accelerated movement of the X-ray tube 3 or the FPD 4 and the preliminary preparation for the detection of radiation are carried out simultaneously. This enables imaging to be started immediately after the start of constant speed movement of the X-ray tube 3 or the FPD 4 without having to wait for constant speed movement thereof to start preliminary preparation of the FPD 4 as in conventional apparatuses. As a result, delays in imaging do not affect the radiation image.
