  • Publication number: 20230125127
    Abstract: A metal titanium production apparatus includes: a reductor that subjects titanium tetrachloride to a reduction process in presence of bismuth and magnesium to obtain a liquid alloy containing titanium and the bismuth; a segregator that subjects the liquid alloy to a segregation process to obtain a precipitate; and a distillator that subjects the precipitate to a distillation process to obtain metal titanium, and the distillator sets an atmosphere so as to preferentially vaporize the bismuth attached to the precipitate and then sets the atmosphere so as to vaporize the bismuth forming the precipitate.

  • Patent number: 11359298
    Abstract: A titanium foil or a titanium sheet is produced by electrodeposition from molten salt using constant current pulse, the method comprising: forming an electrodeposited titanium film on a surface of a cathode electrode made of glassy carbon, graphite, Mo, and Ni, and separating thereafter the electrodeposited titanium film from the cathode electrode by performing one or both of applying an external force to the electrodeposited titanium film and removing the cathode electrode. This enables the electrodeposited titanium film electrodeposited on the cathode electrode to be peeled from the cathode electrode simply and at low cost.

  • Patent number: 9030928
    Abstract: In an example of the invention, network devices are classified into areas. Each of the areas includes edge nodes. A network management apparatus retains fault information including values each indicating whether or not a fault has occurred in each of the areas, retains detour path information including values indicating edge nodes, values indicating alternative areas to the areas and priorities assigned to the alternative areas, identifies, when determined that a fault has occurred in a first area based on the fault information, an alternative area to the first area based on the detour path information, determines, when determined that the fault has not occurred in the identified alternative area, the identified alternative area as a second area through which the active path passes, determines two edge nodes included in the second area, and detect network devices through which the active path passes between the two edge nodes.

  • Patent number: 8774620
    Abstract: An OADM device without a transponder unit does not mount the transponder in charge of separating a fault between the OADM device and an external device and is difficult to perform fault separation and to identify a fault interval. To solve this problem, for the OADM device without the transponder unit, the optical loop back function is provided by using such a switch as, for example, 2×2 optical switch. By identifying a fault developing interval by the use of the optical loop back function, fault separation at the time of occurrence of a fault can be facilitated.
