  • Patent number: 10998161
    Abstract: A thickness of a bonding material (8) is varied in a radial direction orthogonal to a central axis (P) of the tubular anode member (6), the bonding material (8) being used for bonding a transmitting substrate (7) for supporting a target layer (9) and a tubular anode member (6) in a direction along the central axis (P). Thus, a region in which a circumferential tensile stress of the bonding material (8) is alleviated is formed in the direction along the central axis (P) to prevent a crack from developing in the bonding material (8).

  • Patent number: 10504679
    Abstract: Provided is an X-ray generating apparatus in which a likelihood that an anode member may be deformed by heat deformation of a container is eliminated or reduced to maintain a positional relationship between an electron source and a transmission target within a predetermined range, and stable output of X-rays is achieved. The X-ray generating apparatus includes an X-ray generating tube and the container that accommodates the X-ray generating tube. The X-ray generating tube includes an anode that includes the transmission target and an anode member holding the transmission target. The anode member is sandwiched together with a deformable member between the container and a retaining member secured to the container, thus connecting the X-ray generating tube to the container.
