  • Patent number: 9972473
    Abstract: In an envelope rotation type X-ray tube apparatus, a cathode releases electrons, and the electrons released from the cathode are deflected by deflection coils. A target generates X-rays by being bombarded with the electrons deflected by the deflection coils. Here, a shield ring, while allowing passage through a ring interior of those of the electrons deflected by the deflection coils that head for an area of the target set beforehand, blocks electrons heading outward of the area. Consequently, the electrons are inhibited from bombarding on areas of the target outward of the area and an envelope. This can prevent damage to the envelope.

  • Patent number: 8114685
    Abstract: A method is provided, of manufacturing a material to be etched that can more preferably prevent a region to be etched from remaining as an un-etched region and reduce deviation of etched/un-etched regions. Patterning (a method of manufacturing a material to be etched) of a substrate 100, which is manufactured by performing etching through an opened region 10 by an etching mask M1, is performed by a first etching process and a second etching process that is performed after the first etching process. The second etching process is a process for etching a region including a region that is not etched by the first etching process. An un-etched region, which is the same as etched using a virtual etching mask M1?, is formed on the surface of an object to be etched by the first and second etching processes.
