  • Patent number: 9767981
    Abstract: This fluorescent display tube includes an anode and a plurality of filament-shaped cathodes both provided in an envelope, a support as one of a pair of support bodies which support the cathodes is electrically divided for each of the cathodes and at the time of driving, and a cathode driving IC gives pulse voltages to the cathodes at different timing. Since the voltages are applied to the arranged cathodes sequentially, current flowing through the cathode driving IC can be small as compared with a case where voltages are simultaneously applied to a plurality of cathodes. Heat generation of the cathode driving IC is suppressed, and costs required for the cathode driving IC are reduced.

  • Patent number: 9662633
    Abstract: The invention relates to a desiccant suitable for being used with an organic EL element having a solid sealing structure. The desiccant is provided for suppressing any effect on an organic layer, and guaranteeing flowability while being filled. An organic EL element has a container, which includes an element substrate on which a laminate of a pair of electrodes and an organic layer located between the pair of electrodes is disposed, a sealing substrate spaced apart from the element substrate, a sealing agent disposed between the element substrate and the sealing substrate thereby hermetically sealing the container, and the desiccant disposed inside the container. In this configuration, the container is filled with the desiccant, and the laminate is thus surrounded by the desiccant. The desiccant is obtained by mixing a water-trapping agent with silicone.

  • Patent number: 9648712
    Abstract: In an X-ray radiation source, a counter wall made of alkali-containing glass, out of walls of a housing of an X-ray tube, is arranged opposite to a high-voltage region VH of a power supply unit including a high-voltage generation module which generates a negative high voltage to be applied to a filament. This configuration prevents an electric field from being generated in the counter wall and thus suppresses precipitation of alkali ions from the glass. Therefore, it prevents change in potential relationship between electrodes at different potentials such as the filament, grid, and target and prevents occurrence of a trouble of failure in maintaining a desired X-ray amount, thus enabling stable operation to be maintained.

  • Patent number: 9263227
    Abstract: An X-ray tube includes a radiopaque substrate including a window portion, an X-ray transmission window closing the window portion, an X-ray target provided at the window portion from an inner surface side of the substrate, a highly-evacuated container portion attached to the inner surface of the substrate, a cathode, a first control electrode and a second control electrode provided inside the container portion. A shielding electrode is provided at the inner surface of the substrate so as to surround the window portion. Electrons collide with the X-ray target to generate X-rays. Electrons reflected on the X-ray target between the shielding electrodes are absorbed by the shielding electrodes, so an inner surface of the container portion is not charged. The electron emission from the cathode is not affected by the reflected electrons, so a change in target current is small, and thus X-rays of substantially constant intensity can be radiated.
